Final Thoughts and Conclusions
Both the SuperNOVA 650W P2 and 750W P2 power supplies exhibited excellent voltage regulation on all of the DC outputs with outstanding AC ripple and noise suppression. The power supplies feature a good assortment of all modular cables and deliver very good efficiency, meeting the 80Plus Platinum criteria. The only caveat here is that both power supplies struggled a little to meet the Platinum certification criteria while operating on 115 VAC and at elevated temperatures. However, this is not a big deal as the 80 Plus Org certification tests are conducted at room temperature (25°C) and our tests are conducted at elevated temperatures (up to 40°C). Efficiency typically decreases as the temperature increases.
The 650W P2 and 750W P2 PSUs incorporate EVGA’s ECO Intelligent Thermal Control System, which allows the power supplies to operate in silent, fan-less mode at low to mid power levels. During our testing the two P2 power supplies were virtually silent up to mid-power range, even with the ECO fan-less mode turned off.
And last but not least, the new SuperNOVA P2 power supplies are backed by EVGA’s 10-year warranty!
All three of the new EVGA SuperNOVA P2 Platinum power supplies are currently available.
• 650 P2 PSU : $119.99 USD (newegg.com November, 2015)
• 750 P2 PSU : $139.99 USD (newegg.com November, 2015)
• 850 P2 PSU : $179.99 USD (newegg.com November, 2015)
Strengths:
• 650W, 750W and 850W of Continuous DC output at up to 50°C
• Excellent assortment of fully modular cables (flat ribbon-style)
• 80 PLUS Platinum certified, with up to 92% efficiency
• Very clean DC outputs (low AC ripple and noise)
• Tight voltage regulation (±1%) on the three primary outputs
• Very quiet 140mm cooling fan
• ECO Intelligent Thermal Control allows silent, fan-less operation at low to mid power
• NVIDIA SLI & AMD Crossfire Ready
• All Japanese made capacitors for long life and reliability
• 10-Year warranty
Minor Weaknesses:
• Doesn't support EVGA's SuperNOVA monitoring software
• Struggled to meet Platinum efficiency at 115 VAC and elevated temperatures
EVGA SuperNOVA 650W P2 and 750W P2 Platinum Power Supplies
Our thanks to EVGA for sending us the 650P2 and 750P2 PSUs to review – thanks!
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
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.
