I don't like the fact it uses a passive PFC instead of active but it will power your system.

The general rule of thumb is a high quality 500 to 550 watt power supply with sufficient current (amps) on the 12 volt rail(s) can easily power a system with any single video card made. A high quality 700 to 750 watt power supply with sufficient current (amps) on the 12 volt rail(s) can power a system with two video cards operating in dual mode. There are a few exceptions like the new ATI Radeon HD 5XXX series cards which use less power due to their energy efficiency.

so do you know if this INTER-TECH one is good quality? also lets say i had a Corsair 750w PSU instead, would this run it better than my current PSU and actually if mine can run it, is there any perfomance difference?

EDIT: btw with my current setup im trying to crysis maxed out and it can just barely do it, going SLI would make it a lot better right? ^^

The Corsair TX750 is definitely a superior PSU. PSU's don't have a direct impact on performance, usually. I'm not familiar with the Inter-Tech brand so I'm not sure of its quality though being an unknown brand and using passive instead of active PFC doesn't bode too well for it.

Going SLI will easily bring up your Crysis performance.

hmm what does it mean when it has passive PFC? ^^ :p and what is a PFC? XD

Power Factor Correction. It's an efficiency and power distribution feature.

Passive PFC uses filters to keep the signals clean but is subject to anomalies.
Active PFC uses an actual circuit to correctly draw the most efficient current and do other things.

^5 +1 what the Viper said.

The Corsair TX750 is an excellent high quality power supply.

It has the power to do it.

Just keep an eye on it. If you get any weird screen effects or crashes it might be the PSU.

Depends on the model. Those made by Seasonic for Antec are naturally of good quality. Those built by HEC, Delta, FSP or CWT are not as good.

Que ?
Antec Signature = Delta built
Antec Earthwatts = Delta built ( the oem change for the 380/430/500w (from Seasonic) hasn't caused any lack in quality , the 650 and 750 started off as Delta's )
HEC , FSP and CWT aren't even in the current lineup

Had a few problems with some recent Delta's. That's all.

I have to warn everyone about this PSU, because I still can see this shit on market! I know it's an old thread and I'm not a person who made this thread, but I had same PSU. It died yesterday and burned my video card with it. I had GTX560. I torn apart this PSU and I was astonished what I've seen! This PSU claims to have four rails with 20Amps, yes four! Totaling 80A (80*12=960W, hmmm it would be sweet if true), boldly stating total 650W on 12V... There is something wrong here! But when I opened it the PSU is almost empty! I've pulled out the circuit and followed yellow wires, they come out only from two places! On circuit I can see only 2 12V Rails! OMG! Two! DO NOT BUY THIS UNIT! It can pull 40Amps at most.
