The EVGA SuperNOVA 650 P2 and 750 P2 power supplies are rated for a combined, continuous output power of up to 650 watts and 750 watts respectively at 50°C operating temperature. Both PSUs incorporate a single +12V rail. The 650 P2 can deliver up to 54.1A (649.2W) on the +12V output while the 750 P2 can deliver up to 62.4A (748.8W).  And both PSUs include universal AC line input (automatically adjusts the AC line voltage) and active PFC, which make the units more environmentally friendly to the local power grid.

I can add to the list of disadvantages: extremely rigid cabling and very tight connectors (caution is advised with Molex in particular). I have first hand experience with EVGA PSUs and while great as a PSU box little details make them highly questionable purchase. Included cabling for example is by miles more flexible with Corsair. Best thing you can do is to buy cable set from CableMod (not EVGA). You will see then how cables should be made for such premium priced PSU.

Perhaps smaller models have different fans, but I can certainly say that EVGA fans are loudest I've heard in a long time - again Corsair is top of the pick for quiet. Noise from 1000 P2 or 1200 P2 dwarfs multiple HDD arrays and ~20 fans in each system. Ecomode is all nice, but its sole purpose is to shut the racket from cooling fan.

Big EVGA fan, but they shouldn't just auto-copy Leadex/SuperFlower without any improvements.

Also an EVGA fan- and my main selling point is the 10 year warranty. PSUs at these ratings with this warranty at this price are a bargain AFAIC. You are into boutique-ville after this.

I would also like to see smarter PSUs. Cabling is not that big of an issue with me and I love modular designs where I don't have to figure out where to put the excess cables any more. The EVGA I have is not noisy at all.

In all, this review agrees with what I've seen. It has been a great product to me so far.

With such low ripple-
Do the cables have in-built caps???????????????

Something one might want to test sometime-
Does a extremely low ripple PSU like this have any
significant benefit for on-board audio compared to
a cheaper noisier PSU?????????????????

Edit: Yes, small capacitors are built into the ends of the CPU and VGA cables - under the heat shrink. The 650W PSU has one CPU cable with both a 4+4 pin and 8 pin connector. The 750W PSU comes with two CPU cables, one with an 8-pin connector and the other with a 4+4 pin connector.

JG must have a slightly different model to you-his has
capacitors in cables-looks the same.

Yes, you are correct (and I was wrong). I have edited the response above - thanks for pointing it out!

What about the torture load? Did you guys check it on how much torture load it can handle. Because that will give the most accurate idea about how much power supply it can sustain through. Please do the torture load test. I have been asked this question by one of my blog readers where I reviewed this power supply. you can see here (

One thing more I don't like about this power supply which I also mentioned in my review is the plastic connectors on one end are split while the other end is not. Apart from that, it is a great looking power supply and it simply amaze me with its low noise. And yes I agree, the 10 year warranty is the main selling point in this PSU.
