looking into upgrading PSU

post #1 of 15
Thread Starter 
So far my psu is handling my SLI 8800GT's and a CPU OC of 3.0ghz without any major obvious problems but it does seem borderline. I want to OC my processor further and have had it 1 hr. OCCT stable at 3.1ghz but in gaming right after that it crashed, temps were great. One thing in my favor is extreme airflow in my CM690 with 8x120mm fans and my PSU on the bottom drawing cool air up from the bottom and exhausting it out the back. I think that to be able to push much further I need more power. I am looking at a 750W PSU and was looking for advice:

CORSAIR CMPSU-750TX http://www.newegg.com/Product/Produc...82E16817139006

I like the single rail with high amps, most multi-rail PSU's I have looked at only have max of about 22A (like mine does) on +12v rails, the Silverstone 750 I was also looking at only had 18 but had 4.

Would this PSU be able to handle the SLI GT's with high OC and the CPU OC?

Im surprised 600W isnt enough, im pretty sure my PSU could handle 8800GTS's in SLI and still power my quad etc easily, my preference is Silverstone PSU's but i heard the corsairs were pretty good too , 750W should handle that rig NO problem

well you also have to take into account that he is pushing 8 fans, and all of his other external parts, like a printer, external h/d, ect. ect.

Yea the corsair has 60 amps on the 12v and your current one has 35 amps on the 12v,should be plenty.That Enermax isn't very good.

I've never been too fond of Enermax and that Noisetaker is pretty weak on the 12V rail. With overclocking I'm sure it's starting to max it out. You would be fine with the 650 Corsair but the link jameskelsey posted is a great deal.

thanks for the link, just bought it using google checkout for the first time so I got a $10 off for that, and there is a $10 mail in rebate, not bad for the price. Aren't the corsairs made by seasonic?
