The long tradition of EVGA's G2 line continues with the release of its 550 W and 650 W members. The 650 G2 I evaluated today registered excellent overall performance and was dead-silent under normal conditions. The fan kept its noise output at acceptable levels even when I pushed the unit hard, and I had to apply the full load at a very high ambient (47°C) to make it spin at full speed. EVGA uses a low-speed fan in its lower-capacity G2 members, which works miracles when combined with the unit's relaxed fan profile and semi-passive mode. The 650 G2 also performs slightly better than the 550 G2, though only by 1%. While the 750 G2's relative performance is about 2% better, it is also significantly more expensive ($125) and larger, which can lead to problems in small cases.

EVGA's SuperNOVA 650 G2 also sports excellent load regulation at +12V and good-enough load regulation on its other rails. Ripple suppression is amazing, efficiency levels are on par with the competition, and the 650 G2 is very quiet once the going gets though. There are also its high quality components and seven year warranty to make sure you won't have to worry about it for a very long time. EVGA continues its successful march into the PSU market, and products like this one will only further increase their sales numbers. Many users realized that they don't need PSUs with a monstrous capacity to power their systems and inevitably began to search for lower-capacity units, which, aside from being less expensive, offer higher efficiency levels at light loads. The 650 G2 is a perfect PSU for a gaming system equipped with two high-end Nvidia VGAs (or a couple AMD R9 Nanos), and you will most likely keep it for several system builds if you decide to make the purchase since it uses top-notch components and a platform that has proven to be very reliable. For some of you, 100 bucks for a 650 W PSU might look like a stiff price, and it is, but given its features and the quality of its components, I believe it to be a fair price. After all, this PSU will last you for many years to come, which surely justifies the cost.

There is the 550 G2 unit for 10 bucks less should you need a PSU for a single-VGA system you don't intend to upgrade with a second VGA in the future. However, given the low hold-up time of the 550 G2—at least with my sample—I would gladly pay the small price difference for an upgrade to the 650 G2.
