The SuperNOVA 650 G1+'s overall performance is pretty high, despite its lousy transient response. Good efficiency levels carry this PSU's score.

Performance Per Dollar

The following chart may be the most interesting to many of you because it depicts the product’s performance-per-dollar score. We looked up the current price of each PSU on popular online shops and used those prices and all relative performance numbers to calculate the index.

The 650 G1+'s value score is lower than what EVGA's own 650 G3 achieves. Seasonic's SSR-650FX sets itself apart as the best buy in our chart. It's also much more compact, measuring just 140mm deep.

Noise Rating

    Your review is based on the $110 MSRP. This PSU is currently selling for $69.99 on Amazon. Would you highly recommend this PSU at this significantly lower price point?

    The EVGA G3 650W can be bought for $69.99 also and it's much preferable.

    Like about 2/3 of the 850 or so individual PSUs EVGA is selling, I can't figure out exactly who the target market is for this.

    Calling this G1 "SUPERNOVA" is a bit on the nose.
    These are manufactured by FSP.

    EVGA's excellent G2 and G3 SUPERNOVA's are manufactured by SUPERFLOWER....
