DH Review: Hiper Type-R MKII HPU-5K880 / HPU-5B680

Read The Review Here
________________________

Hiper were first known within enthusiast cycles for their Type-R PSU series released back in early 2005. Its many features, good looks and relatively competitive price made it a very reasonable choice of unit for a powerful system of the time. Three years have passed and Hiper have decided to completely redesign and revive the Type-R series, announcing the Type-R MKII units. 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.

loving the review as always Grace
but, no modular.......
the one thing that tipped the scales for me when I bought my type R mk1, it was modular. so I'm a little disappointed with that. still, the tests speak for themselves, they are awesome performers. and I love the charging point too, thats a great idea
just... something not as "wow. cool" about these... can't explain it really. they're a bit samey..

Just reading the specs and i for one wouldnt touch these with a 10 foot barge pole

Fan Specifications.
Bearing Type Sleeve Bearing

there still useing the same crap sleeve bearing instead of ball bearing fans
this probably woudlnt bother the typical noob but from past experiance its the fans that go first on these psus.

There design might have changed somewhat but there still useing the same types of fans they used in there old hyper psus....

i would stay well away and just knowing that i wouldnt gave given them a editors choice award.....

those that buy it im just warning you now, dont say i didnt warn you.

things to look out for when your buying a new PSU, Internal Build quality and Fan Type and Fan Speed and Noise and Amperage, Not watts Amps. if there not up to the job stay well away.

Hello Virus,

I'm afraid I don't agree with you on that. True enough, ball bearing fans are (supposedly) more reliable than sleeve bearing fans. But:


Ball bearing fans generate more noise across the whole RPM range, require more power, need much higher starting current and in a cooler environment will actually degrade faster than a sleeve bearing fan.

Ball bearing fan engines are truly better when talking about high speed (>3000rpm) fans. When talking about a fan with a top speed of 1800rpm which will be working at 1000-1200rpm under normal circumstances, they make no sense at all.

Yate Loon 135-140mm fans are very popular among PSU manufacturers, and they are pretty reliable too. But no, that's not the same fan as the one used in the previous Type-R series units.


In short, ball bearing makes sense only if we are talking about high speed fans or fans which will be exposed to high temperatures. If you compare two 1200rpm fans, one with sleeve and one with ball bearing, the sleeve bearing fan will actually outlive the ball bearing fan if working at 30 Celsius degrees. The life of the sleeve bearing fan will dramatically degrade if the temperature is above 50 degrees, which is why most cooler fans are ball bearing.


Finally, you won't be able to find many ball bearing silent fans about. All silent fans have a sleeve bearing or other, propertiary bearings (e.g. Hysint bearings). Ball bearing fans even if they are silent at first, their acoustic performance dramatically degrades in matter of months.



Everything has its uses. Sleeve bearing fans have theirs, and using them into a rather cool and quiet unit is one of them.

An interesting paper that examines the Sleeve vs Ball Bearing issue:

Interesting read. Although I don't agree with everything it says (mainly the test results, there is no mention of any of the testing conditions, the fan speeds, the manufacturer of the sleevings, etc. Given that some tests would last like a...decade, that's more theory than practice) it is interesting to note that according to it a sleeve bearing fan will last 52000 hours @ 40C. That's 6 years of 24/7 use.

Quite reliable for a PSU which sadly is expected to be upgraded while it's well within its 3 year warranty, I'd say.

Come on man

Sleeve vs Ball bairing ?

its a no brainer. from past experiance sleeve fans have always failed on me, where as ball bairing has been great.

doesnt matter if they use more power and it doesnt really matter about noise
most if not all psus i have bought that are ball bairing arent noisy at all...
the power issues are a none brainer aswell as the fan draws it power via the psus circut board that draws that from your wall socket not the actual psu current.

Grace

Sorry, no men around my place...


Power and noise are primary concerns of PSU manufacturers. And when under the same circumstances a sleeve bearing fan will last the same as a ball bearing fan, will consume considerably less power, will generate only a small fraction of the vibrations a ball bearing fan does and will be considerably quieter, it is pretty rational to use a fan which will work just as well in that certain environment and will outlast the life of the unit itself.


What you said is not only entirely wrong, but also funny. Of course the PSU fan works with power from the PSU, the same power your PC will get. They are DC 12V fans, not AC 110/220V fans you know! There is no separate power circuit for the fan itself. The fan is powered via one of the 12V lines.


I don't know what your past experiences are, but if all sleeve bearing fans were to fail about 75% of the high end power supply units currently available from reputable manufacturers alone will fail soon enough.

ViRuS2k

woops its a girl, :P howdy lol

anyway yeah pritty funny about the power circut as your right hehe
but your wrong about sleeve vs ball bairing.

sleeve will never outlast ballbairing,
they may have the same MTF but they are just not made to last as long as ballbairing.
its also common knowledge around the net and google that sleeve are not as reliable as ball. its simple that simple.

every psu i have had i have had 3 fail on me 2 becuse of fan rattleing noises and 1 becuse the fan completely stoped and the psu burnt out !

either way i still stand by what i said about sleeve vs ballbairing...

virus, as much as I like you dude, you need to zip up the pants mate and listen to grace, she is a PSU specialist and has worked for a long time in this industry. I don't think she is saying that one specific fan style is "better", rather there are certain applications for both.

Also its "ballbearing" mate.

ViRuS2k

doh

well m8 personaly yes they both function the same but im just going on past experiance with those types of fans. im not saying to grace that i think she is wrong when it comes to the technological side of things im just saying i favor personaly ball *bearing hehe* over sleeve

dont want to step on toes or anything also the debate me and grace where having was not so much about PSUs it was the fans thats inside them.

Necrosis

Sleeve's are quieter too.

Zardon

Yes I know what you are saying, but Grace was explaining the technological differences between the fans rather than what you have personally experienced in the past. I mean going on this theory I would never own an OCZ power supply again as i have had 2 fail on me in a year, but thousands of people have had good experiences with the very same units. You need to just check the way you speak to people rather than saying "ah come on man, its a no brainer", say something like "well I personally have experienced issues and feel more comfortable with ball bearing for xxx reasons". Otherwise it sounds like you are just dismissing technical replies to your queries.

No toes stepped on, I just didn't want this turning into a 3 page debate with you telling Grace she was wrong, when really all you are basing your replies on are your personal experiences rather than technical fact.

If its any consolation, I agree with you on the choice of fan, however there are reasons why some makers choose sleeved, which is really all grace was trying to say in the first place.....

Now that was one bad PSU. You know, every good PSU (matter of fact, almost every PSU which costs more than 30$ nowadays) will simply shut down if overheated. Heating a PSU up reduces its power delivery capabilities. So when the high temperature makes it unable to deliver the power your system needs, its overload circuit will shut it down. In case the PSU is too powerful or if its heatsinks are large enough, it can work without the fan at all if the power load is small compared to its output (up to 25-50% load). Of course it will run quite hot and its efficiency will be pathetic, but still it will simply keep working.
