Pros, Cons And Final Verdict
You can't go wrong with a high-end G2, P2 or T2 EVGA PSU. They're all based on cutting-edge platforms manufactured by Super Flower, which EVGA sells hand over fist (especially the Gold-rated G2 models). Only the latest Corsair RMx models look to be worthy opponents, especially now that they have an upgraded warranty that matches EVGA's.
The RMx series mostly competes with EVGA's G2 line-up though, which means the P2s practically play alone in the market. We say practically because, in the 750W category, Seasonic's Snow Silent-750 goes head to head against the 750 P2's performance, although it costs more and has a shorter warranty.
With a wide wattage range, the P2 line addresses a large portion of enthusiasts who don't want to empty their wallets for Titanium-class efficiency, but instead would rather buy a Platinum PSU for less money.
In our opinion, power supplies are investments. Aside from enabling lower electricity bills, good PSUs also protect your PC hardware in case something goes wrong and extend the life of your components through clean power. The more ripple in a PSU's rail, the lower the DC quality and higher the stress on voltage regulation circuitry. The same goes for increased voltage deviations, which also apply huge stress on VRMs. This is why ripple suppression and load regulation are the key factors for a PSU's performance, with efficiency following closely.
The EVGA SuperNOVA 750 P2 registers very high performance in all areas. On top of that, its modular cable design, Japanese caps, reliable fan and hefty 10-year warranty complete the picture. The only area where this unit doesn't come close to the top is noise output. The 750 P2 definitely isn't a noisy unit. On the contrary, with the semi-passive mode enabled, it makes zero noise under light and moderate loads. Still, with a better fan profile and ideally with a fan featuring a lower start-up voltage, its overall noise output would be way lower. EVGA used the same fan in its 850 P2 and we don't think it's the best choice. The company should instead consider the 650 P2's lower-speed fan. At its slowest speed, that model only outputs 26.5 dB(A) compared to the 750/850 P2's 35.9 dB(A). That's a huge difference, which naturally has a major effect on the overall noise output of the higher-capacity P2 models.
