Corsair TX650W PSU

by Grace | 20th January 2008

Attempts to diversify are common among PC component manufacturers, but these are not always marked by success. One of the most successful diversification attempts was made by Corsair nearly a year ago. Corsair, being a highly reputable RAM manufacturer at the time, released a small range of high class PSUs aimed towards enthusiasts, with the "HX series" moniker. We reviewed the HX620W unit back then which we found an excellent choice for enthusiasts and a year later the HX620W is still one of the best choices for performance systems. Because of the great success of the HX series, Corsair launched the VX series back in August and the TX series shortly after that. The VX series units are aimed towards the value-conscious PC users, however our review of one of the first VX450W units was a surprise because of its remarkable performance.

by Grace | 14th December 2007

Not everyone needs a monstrous 750W+ power supply unit for their everyday home or office PC, but most people would pay for a little extra in order to own a low power, high quality unit. Silverstone hope to address this with the release of the ST35F. The ST35F has a maximum power output of only 350W, more than enough for an average home or office PC which is not designed for heavy gaming or overclocking. Let us have a closer look at it and see if it’s worthy of the extra money over an OEM unit.

Hiper Type M 4M630

by Grace | 6th December 2007

Hiper were first known within enthusiast cycles for their Type-R PSU series released back in early 2005. We reviewed two of these units a few weeks ago and found them to be good products. That said, the Type-R units were marketed firmly at enthusiasts and could not compete against aggressively priced units in the value conscious sector. To address this Hiper introduced the Type-M series back in early 2007. We have a Hiper Type-M 630W unit for review today.

These MKII units are entirely different than their predecessors, both in terms of features and appearance. Today we will thoroughly examine two Type-R MKII units, the HPU-5K880 and the HPU-5B680.

by Grace | 23rd October 2007

We reviewed the powerful 800W, 1000W and even the monstrous 1600W X3 units in the past, and we found them to be excellent performers. Not everyone has the funds to buy one of these units however so today to complete our coverage we will review the Ultra X3 600W. The Ultra X3 600W unit is the only unit of the series which offers a very competitive price/performance ratio with its price tag being nearly half that of the 800W unit directly above it.

NorthQ Silent Lightning 400W

by Grace | 28th September 2007

We have tested and reviewed many top end power supply units here at Driver Heaven. However, most people do not need a wallet sapping 1kw unit. For example, buying a unit which can output 800W+ for a PC which is used for office applications or web browsing is insane. Today we have an interesting unit from NorthQ for review, the Silent Lightning 400W. While the 400W maximum output makes it suitable only for low to middle range systems, NorthQ have attempted to create a good looking unit, to make it stand out from the crowd.

The M1000 is a high class modular unit capable of delivering 1kW continuous power and has a peak power rating of 1.2kW.

The big question, "So is it any good?" will be answered today.

It has four 12V lines and boasts a load of features. Through the review we will try to find out if this particular unit can live up to the Akasa’s hard earned reputation throughout enthusiast circles.

Hiper Type M 670w Power Supply

by Grace | 3rd May 2007

Here at Driver Heaven we strive to provide you with useful and thorough reviews and for that we have built a custom power supply testing station which allows us to efficiently analyse any consumer and industrial AC to DC power supply unit available. "High Performance Group, most commonly referred to as Hiper, is a newly found UK based company which has became well known for their high performance power supply units. Hiper acquired most of their fame for the Type-R series which was released a few years ago. The Type-R series were high performance modular units but a lot of attention was given on their aesthetics factor. Today we will take a look at another approach from Hiper, the Type-M series. The Type-M series are not modular and look quite simple, but they are considerably cheaper than the Type-R series and apparently perform just as well or even better. We will soon see if they are worth your time and money."

NorthQ Pacific 400W Fanless PSU

by Grace | 30th March 2007

If you want to build an entirely silent PC, you have to (logically) either take out or replace everything that generates noise. Every moving part inside a PC generates noise, mainly fans and hard disk drives. A common source of noise that comes from a PC is the power supply unit. These high power devices require cooling and so there are fans installed inside them. A cheap, less efficient or extremely powerful unit is commonly cooled by a fast, noisy fan. As of late, companies try to make their units more ‘user friendly’, making them more efficient so as to require less cooling, and therefore to be as quiet as possible. Nevertheless, for something to be entirely quiet, it has to be missing any moving parts. And so some companies introduced extremely efficient, fanless power supply units which generate no noise at all, for the most demanding of users.

Zippy Emacs 500w PSU

by Stuart Davidson | 13th March 2007

When it comes to power supplies in the mainstream market it would be fair to say that the name “Zippy” wouldn’t be the first to spring to mind, however since 1993 they have been manufacturing PSU’s for servers as well as redundant power supplies. They also produce a range of keyboards, mice, ceramic components and switches - they are a versatile company in the truest sense of the word. Recently Zippy launched a range of Gaming PSU’s and today’s review product is one such model. The (HP2-6500PE(G1) ) is a 500w SLI certified model which is aimed at mainstream systems rather than the ultra high end. Let’s see if Zippy can take the reliability of their server PSU’s and add gaming performance to the mix.

Ultra X-Finity 800W QR ATX PSU

by Dyre Straits | 28th February 2007

Today’s PC gaming rigs require Herculean muscle to get things working like they should. This is especially true with the recent next-gen games. This constant increase in demand is causing a lot of debate among gamers as to whether it’s worth the effort and cost to keep upgrading a PC to take advantage of all the new eye candy and physics that are evident in the 3D environment. Many previous die-hard PC gaming fans have opted to go with consoles in an effort to avoid the constant cost of upgrading. However, those of us who love our PCs and love the games they play, eventually bite the bullet and put out the funds to keep feeding the beast. The rewards are often received with mixed reviews, but, once the dust settles, many of us find no better satisfaction in gaming than on our own private PC. One company that is very keen to listen to the demands of the PC gamer is ULTRA. Arriving on the scene very recently, ULTRA has pushed the envelope to provide what the demanding public wants: More POWER and then some!

Ultra X Pro (QR) 800w AST PSU

by Dyre Straits | 6th February 2007

We’re going to be reviewing one of the Ultra Power Supplies (PSU) today. They offer a Limited Lifetime Warranty on all their Power Supplies. Keep in mind, however, that to qualify for the extended lifetime warranty, the product does have to be registered with the company within 30 days of purchase. We have yet to determine how stringent this requirement is, but it does pay to read the fine print.

Enermax Galaxy 850W PSU

by Stuart Davidson | 13th January 2007

We have been using an Enermax Noisetaker PSU in one of Driver Heaven’s benchmarking rigs for some time now and it has performed flawlessly. Since we installed that PSU every component in the system has been upgraded and while the Noisetaker still performs admirably (even when powering a 8800GTX SLI system) we felt it was time to move to something more powerful for futureproofing … their Galaxy 850w supply.

Ultra X Connect VS 700w

by Grace | 8th December 2006

The introduction of quad core processors along with multi CPU and multi GPU systems has dramatically raised the demand for strong power supply units. With the introduction of units rated as high as 1KW, it is clear that 300-350W power supply units are becoming a thing of the past. Today we will take a look at the Ultra X-Connect VS 700W power supply, those with good memories will remember Ultra introduced modular power supply units to the PC world. As strange as this may sound to some, this is not a power supply unit for the hardcore enthusiast but mostly aimed towards gamers and modders.

Corsair HX620w

by Grace | 23rd October 2006

Corsair is a company whose name is synonymous with quality RAM, however they have slowly tried to diversify by creating water-cooling systems for enthusiasts (the highly acclaimed Nautilus). Today we are looking at another product in this expanded range, one of their new high quality power supply units, they offer two models in this range, the HX520W and the HX620W. We received the higher specification 620w unit for testing today, so let us see if it lives up to the high standards we associate with the Corsair brand name.

Ultra X-Finity 500W and X-Finity 2G 600W

by Grace | 11th October 2006

Ultra is a well-known manufacturer of computer components even though they are relatively new on the scene. They has a vast product line and mostly focus on power supply products, since these are the products that put them squarely on the map. Ultra virtually invented the modular power supply units after all and their first modular power supply units were a great success. Today we have two new power supply units from Ultra, the X-Finity 500W and the X-Finity 2G 600W. Ironically, neither of them are modular, but still both of them are high class units.

Spire Rocketeer VI

by Grace | 28th September 2006

Spire is an old and well known company specializing in creating computer component cooling products. They have a very wide range of cooling products consisting of various heatsinks, fans and special accessories. Recently Spire expanded their products range with designer computer cases and power supply units. Today we are going to have a look at their best power supply unit, the Rocketeer VI. The Rocketeer VI is the most powerful unit Spire currently offers and by far the one with the most features.

Enermax Noisetaker 600w PSU

by Stuart Davidson | 24th September 2006

When building a high performance system quite possibly the most important choice of component is the power supply. There is no point in building your very own home made supercomputer to have it powered by a low end supply that has problems holding a good rail. Many users fall foul of the misconception that “the higher the wattage the better” where as others feel they can save money on something they deem as unimportant. When building our Driver Heaven review systems we take time to look at the variety of supplies and to decide whether they can take the extreme load we have to throw at them when reviewing the highest end hardware. When deciding to build a gaming system based around the latest array of hardware such as AM2 and Conroe with either SLI or Crossfire delivering the graphics it is extremely important to purchase a unit which will ensure you end up with a stable system.

NorthQ 4800-400

by Grace | 15th September 2006

There are hundreds of power supply units currently on the market ranging from the cheap to the expensive, from the beautiful to the ugly and they all come with various output ranges in classic or modular design. Only a few of them however offer special features and functions which can make them that little bit different. Today we will take a look at a unit from NorthQ which comes supplied with a remote control. A pioneering feature for a power supply unit, meaning you do not have to keep your case close to you (or even a case at all) in order to turn the system on and off.

Cooler Master iGreen 500 watt PSU

by Chaos | 7th August 2006

Today we get to look at a new power supply from Cooler Master in the form of the the iGreen 500w PSU. This power supply is designed to meet the latest environmental emissions regulations by adhering to both Energy Star and Blue Angel standards.

Zalman ZM460B-APS

by Asmoday | 3rd August 2006

We recently reviewed the Zalman CPU coolers CNPS8000 and CNPS9500 AM2 here at Driver Heaven, and were very pleased with how they performed. Now its time to have a look at another of Zalmans recent products: the 460W Noiseless Switching Power Supply.

Be-Quiet Straightpower series

by Grace | 31st July 2006

Be-Quiet have impressed us in the past with their high quality power supply units. Their DarkPower series have always been a very good choice for power users, enthusiasts and those of us addicted to silence. It would be fair to say that Be-Quiet have not been able to compete in the mid range sector because their power supply units, although very reliable and powerful, tend to cost too much for the “average” user. Be-Quiet have decided to address this situation by releasing the StraightPower series, which retain many of the features of the DarkPower series with extremely competitive pricing.

North Q 4775-500S PSU

by Grace | 16th July 2006

Today we have another product from North Q on our review bench, the best power supply unit they offer, the 4775-500S “Godzilla”. While it is not likely to be crowned the best power supply unit that was ever built, it has several distinctive features and boasts specifications which should satisfy all but the most demanding enthusiasts.

Ultra X-Connect X2 550w SLI Modular

by Chaos | 28th June 2006

Today we get to take a new offering from the folks at Ultra. We are going to take an up close look at their newest modular SLI ready power supply the Ultra X-Connect X2 550w PSU. Unlike the standard power supplies that have all the cables attached, the Ultra X-Connect comes “naked” with no cables attached. Thanks to the modular approach that Ultra takes, the cables are separate and can be plugged in only as required. Not only will this help reduce clutter inside your PC but it also leaves you with the option to add additional cables only if you add new devices to your system. Another beauty of the modular design is increased airflow within your PC chassis.

Cooltek CT 600 Ultra Silent PSU

by Asmoday | 22nd June 2006

Cooltek is a European based brand with various cooling products but with Main focus on power supplies. The products are designed in Scandinavia and Germany and produced in selected factories in China. Here are some words from our Swedish Cooltek representative Jesper Brenner: “We are dedicated in using high quality components inside our power supplies and only working with manufacturers we know can make products with a high, consistent quality. We visit all manufacturers’ factories as well, to control their routines and to ensure that the employees have a decent working environment. I'm telling you all this because I would like you to know that we are not just another "re-labelling" brand! Our power supplies may be a little bit more expensive than the competition, but they offer real wattages and stable voltages combined with low-noise, quality (Papst) fans."

OCZ Game XStream 600W PSU

by Zardon | 14th June 2006

It’s always fun to wake up at the crack of noon after hearing a loud knock at the door and opening it to discover the postman bearing gifts, and I didn’t even have to blackmail him for a change! Clutched in his sweaty hands was the object of my review, the Game XStream PSU sent to me from the nice folks at OCZ. OCZ are very well known for their excellent line of memory for overclockers and enthusiasts who want to get the most from their machines and have recently branched out into offering other quality products such as power supplies.

Be-Quiet Dark Power Pro 530w

by Grace | 9th June 2006

We recently had the chance of taking a closer look at the Dark Power P6-470W power supply unit from Be-Quiet, a company based in Germany. For this review we will be concentrating on a similar power supply unit by the same company, the Dark Power Pro 530W. The Dark Power Pro line is not intended to replace the Dark Power P6 line; it's merely an evolution of the latter with more features. There are several differences between the two units, with the main difference being the fact that the Dark Power Pro unit is modular, where the older P6 was not. The Dark Power Pro is designed to be as silent as possible while delivering high power loads and reliable enough to be an assessable part in high end systems.

Cooler Master Real Power 550W PSU

by Chaos | 20th May 2006

To follow up on the success of the Real Power 450W PSU, Cooler Master has released the new Real Power 550W SLI. It complies with both the Intel standard ATX 12V V 2.01 and SSI standard EPS 12V V2.1. They recommend the Real Power 550W as a viable solution for high end workstations and gaming rigs that contain those power hungry dual graphic card solutions based on SLI or Crossfire technology. The Real Power 550W PSU has dual output connectors for PCI Express VGA cards and has intelligent fan speed control and “real power" capacity that will help to maintain the stability and reliability of your computer system even at the most demanding moments.

Xion PowerReal 600w

by Grace | 11th May 2006

The Xion PowerReal 600W v2.01 is a high end, SLI ready unit which boasts a number of features, primarily aiming towards the enthusiast sector. The list of features is extensive, ranging from fan speed control to dual 12V rails. The unit is not modular and this might drive away some of the hardcore modders or HTPC users instantly.

NorthQ 4001EXT + 4775-400 PSU

by Grace | 29th April 2006

Today we will take a look at two power supply units from NorthQ in the shape of the 4001EXT and the 4775-400, which are rated for 400W maximum output. Although their rated total power output is the same and their basic architecture is akin, we will soon see that they are two entirely different units. Let us have a look at the specifications first.

Be Quiet P6-470 Darktower

by Grace | 12th February 2006

Many people want or need a completely silent PC for their home or work. Unfortunately, as computers become faster, their power requirements and heat dissipation also grows higher. Both of these problems affect the power supply units, which have to provide more power while remaining quiet and cool. Cheap power supply units have to use powerful fans for cooling, which makes them rather loud for using in HTPC systems or other systems which need to be quiet. Thus many companies strive to design more powerful and efficient power supply units, which not only are able to provide great amounts of power but also to dissipate less heat and require less cooling. Be-Quiet is a rather new German company, subsidiary of Listan, which focuses on creating computer related products, like coolers and power supply units, made to reduce the noise output of your PC without compromising quality and/or performance. Today we have the latest version of their power supply unit line, the P6 DarkPower PSU. Let us take a close look at it.

Antec Neo HE 550w

by Asmoday | 13th January 2006

The Neo HE is somewhat different to most other power supply units and we do not mean that because it is a modular type power supply unit as there are many of these around these days. The Neo HE is relying on its own high efficiency factor to solve all of the problems that a power supply unit may face and it is this that makes the Neo HE so different.

Enermax Liberty 400w PSU (Modular)

by Stuart Davidson | 29th December 2005

We’ve looked at numerous supplies here in the past and on the whole they have all been high specification units and those generally come at an equally high price. It goes without saying not everyone has a huge budget to work with, however stability is still an important factor. So today we are going to look at Enermax’s mainstream model which comes in at 400w. Enermax are not a company known for skimping on quality so we should be in for a treat at a very reasonable price.

Thermaltake PurePower Power Station 520

by WxChaser | 3rd December 2005

In 2005 another of Thermaltake's innovative products entered the retail scene, in the form of a well thought out modular power supply. The Thermaltake PurePower PST 520W series was introduced, and is totally compliant with published ATX 12v 2.0 version standards. The Power Station 520W PSU consists of the 5.25 inch P.S.T. (Power Station) that fits into an available 5 1/4 inch drive bay, and includes a mini-P.S.T. for connection of low power accessories such as case lights, fans, etc. The only connections that are made to the parent power supply are an 8-pin power connector which reaches from the power supply to the 5 1/4 inch Power Station, and dual connections are inherent for the 6-pin PCI Express power connectors on the back of the PSU itself.

XG Magnum 500W

by Asmoday | 30th September 2005

Mike has spent some time with a pretty impressive looking power supply unit from MGE. How does 500w with 30a on the 12 volt rail with almost silent noise levels, a funky looking blue LED, copper heatpipe design backed by a lifetime warranty sound?

Enermax 535W All-In-One

by Stuart Davidson | 3rd July 2005

Based on the results of our testing to say the Enermax 535w All In One has strong +12 and +5v performance would be a complete understatement. The figures shown are actually the highest we have seen achieved by a PSU to date. This includes the higher spec 600w models previously tested. Throughout the testing period there was not one stage where the Enermax unit dropped below +12v, generally maintaining a voltage of 12.16 or above and the +5v results never wavered from 5.107v. These results are spectacular and indicate complete stability within the unit.

MGE Xtreme Gamer Vortec 500w PSU

by Stuart Davidson | 19th February 2005

I’ll be honest, before being given the option to review the Vortec PSU I’d never heard of MGE Company (XG – Extreme Gamer) so was a little sceptical as I headed to their website… what I wasn’t expecting was a product catalogue of such cool looking components as the Vortec PSU and the Dragon/Viper cases. You can’t help but be impressed, So with great anticipation I accepted the Vortec 500w PSU as a review item and waited for it to arrive…

Ultra 600w

by Zardon | 18th December 2004

This 600w varies from the Xconnect model we reviewed in the fact it doesnt use the modular xconnect style connectors but the more traditional design as seen in the images directly below. Ultra also offer a 3 year warranty with their products which isnt to be sniffed at.

Ultra X Connect 500w PSU and UV Kit (Update)

by Stuart Davidson | 3rd December 2004

A few months ago we looked at our first Ultra product, the Ultra Xconnect PSU. The quality of the unit came as a complete surprise to us considering we’d never heard of Ultra before that point. Since then we’ve looked at a few other Ultra components, such as MP3 players and Cases and each time we’ve come away impressed. Today we have an updated model of the X-Connect in for testing. Essentially it’s the same internal components and performance as the older model so we will only be summarising the new PSU design here. We recommend that you read the full Ultra X-Connect review for detailed information on the unit.

OCZ Powerstream 600w

by Zardon | 13th November 2004

The PowerStream range is made for OCZ by ToPower under a close manufacturing deal that means OCZ are the only supplier that will have the PSU with these specs.

Ultra X Connect 500w PSU and UV Kit

by Stuart Davidson | 8th August 2004

When building a PC there are usually 2 schools of thought. The first group just wants a bog standard PSU that "works" and for the most part a generic PSU will suffice and these generally cost £20-£40 ($35-$60). The second group want a high end supply that can handle the highest spec components costing around £100 ($150). The PSU we are looking at today is made by Ultra who claim it delivers high end performance for a reasonable cost ($110/£80). It also sports some unique features combined with a very appealing appearance.

OCZ Powerstream 420W

by Zardon | 29th May 2004

OCZ are famous for making some of the highest quality memory on the market and over the last year ive had the pleasure in reviewing many of their modules, they have also been diversifying their product range with heatsinks, ram-sinks and most recently they have made a bold step into the power supply enthusiast sector. I am taking a look at the new PowerStream 420 (OCZ-420ADJ) PSU.
