(Ultra X-Connect/OCZ PowerStream) PSU Deathmatch

*AndyOCZ* · Sep 19, 2004, 06:59 AM

Well, the OCZ PSU was designed NOT to intake air from your CPU. Heating up the PSU is a bad thing. It causes your available power output to decrease dramatically. The original ATX spec called out to intake fresh air from outside into the PSU, and then to blow the air onto the CPU. Needless to say that only heated the entire case up and caused problems. It was then reveresed to draw air from inside the case.

In the BTX design, the cold intake air from the front of the case blows over the CPU first, since the CPU has been moved to the front of the case. Therfore the PSU can not draw hot air off of the CPU because it's not there. As I stated earlier, it is not good to draw hot air through the PSU for ATX either. You should be removing this hot air with a case fan.

agreed.... understand now were you coming from.... i'm not currently aware of the way the BTX full Form Factor case will mount the PSU...... i knew of the cpu being moved and the arrangement of other components....

thanks for that input.. greatly appreciated....

Gah. I've pondering this decision for many days now and I have to decide today. Why must both products pwn so much

I was so torn when the Ultra came out because it was so stable and had all the cables sleeved.

But ultimately I would go with the OCZ since they can go WAY past their rated wattage (520W PSU able to reach 600+ watts!!)

I look at it like this - I could always sleeve those OCZ cables myself, but I could never be able to get that extra wattage later with the Ultra.

can you tell me if the ocz powersupply is ATX12v v2.0 Compliant? (like the neopower)

Is it important/futureproof?

The ATX12v v2.0 change very little. Elimination of the -5v line was about it. The -5v line is no longer used by systems, so it's elimination was likely a cost saving feature.

The OCZ PSU will work in any situation that an ATX 12v v2.0 PSU will and some that it won't, so if that makes it compliant then the answer is yes.

The OCZ Powerstream is BTX ready. This is why it comes with a 24 pin connector. SO, this makes it as future proof a PSU as there is available.

Either way I'm sure your in a win\win situation either way which ever you decide. I choose the Ultra X-Connect due to it's solid rails and of course the modular cables. I don't regret it; but I'm sure OCZ makes a good product as well.
