A Detailed Look
The EVGA SuperNOVA P2 power supply enclosures are painted with a matte black hammertone finish and measure 165mm (6.5”) long. The back panel includes an On-Off switch, AC receptacle and open honey-comb grill.
Around on the front side, you will note a small 2-position switch up in the top-right corner in the photo above labeled “ECO OFF/ON”. The SuperNOVA P2 power supplies incorporate EVGA’s ECO Intelligent Thermal Control System for fan speed control. This allows the end user to select silent, fan-less operation for low to mid power applications if desired. Unlike some previous SuperNOVA PSUs, the switch is located on the front of the power supply instead of the rear, which makes the switch harder to access once the PSU is installed.
With the ECO Thermal Control System turned ON, the power supply cooling fan does not start spinning until the internal component temperatures reach a pre-programmed setting. The fan then starts out at low speed and gradually ramps up based on load and temperature (see graph above).
Both power supplies use a 140mm, seven blade fan on the bottom for cooling. The Globe Fan (RL4Z B1402512HH) is rated for 0.50A at 12 VDC and is controlled by the ECO Thermal Control System. It features dual ball bearings for long life and quiet operation.

(EVGA SuperNOVA 750W P2)
The front panel on the 650W P2 incorporates nine modular cable connectors while the 750W P2 has twelve, along with the ECO fan mode control switch, all nicely labeled.
All of the modular cables are sleeved with a black nylon mesh covering. The cable sets for the 650P2 and 750P2 are very similar, except the 750P2 gives you one extra EPS (CPU) cable, two additional 8-pin PCI-E cables/connectors, and an additional SATA cable.
I can add to the list of
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
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?
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 (https://www.glinkster.com/best-power-supply-for-gaming/)
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.
