Influence of PSU on OC ability

post #1 of 20
Thread Starter 
Does a PSU have any influence on OC'ing capabilities ? If so, how much ?

Thanks

Generally no. If your PSU does effect your overclocking... then your PSU is very very bad.

Howdy,

I am new at this myself, but from personal exp. I found that the PSU has a lot to do with a succesfull OC. When I OCed with a cheap PSU I was not all that successful, but when I upgraded to a HE OCZ with all the same settings it ran like a charm. I guess with the cheaper units the voltages are not all that stable and most do not run at the wattages advertised. Spend the extra $$ on a good PSU, you won't regret it.

Your PSU may have a bit influence on OC'ing. For instance, 12v rail has huge fluctuation liked +/- 6%.

Agreed ^^^

Better PSU's have better quality components, thus better voltage regulation under load [much more important than voltage regulation levels at idle]. Ideally, you want to be using no more than ~85% of your available current..and no less than 50-60%, as components such as capacitors and VR's have a more difficult time, maintaining a marginal load.

The reason I asked this is because of my SLI setup with 9600gt. I have a Enermax Liberty 620 atm ( 600w ) and before I went to SLI I could run my computer at 3.7/3.8 ghz. After I installed SLI, I had to drop back to 3.6gz otherwise I got BSOD's all the time.

:'(

Anyways, wich PSU would you recommend ?

I have a few in mind:

OCZ GameXStream - 850w
Enermax INFINITI - 720w

+/- 6% = Not a PC PSU, it's a bomb!

I wouldn't touch a PSU that is worse than +/-3%

Have you tested your CPU stability? It could be your motherboard.

Price range on PSU?

do me a favor and list the 12v specs [# of rails and amperage] as well as the efficiency rating for both.

Best = Highest efficiency rating, and highest # of amps on the 12v rails.

I think your Enermax Liberty 620 is fine. If you have 4X1GB ram, give 2x1GB a try or run the stress test again.

Well I did some stuff with OCCT yesterday, and I noticed huge spikes on the vcore, and with huge I mean 47% It went from 1,47 to like 2,20..then back to 1,47 ofcourse. And also, I usually dont see the correct readings in PC probe. Like it says my nb is running 4.01v and sb 4.01v too etc...

So thought might have been the PSU..
