Cross-Load Tests & Infrared Images

Our cross-load tests are described in detail here.

To generate the following charts, we set our loaders to auto mode through our custom-made software before trying more than 25,000 possible load combinations with the +12V, 5V, and 3.3V rails. The load regulation deviations in each of the charts below are calculated by taking the nominal values of the rails (12V, 5V, and 3.3V) as point zero. The ambient temperature is between at 30°C (86°F) to 32°C (89.6°F).

Efficiency Chart

The 650 G1+'s efficiency landed in the 90-92% range from 125W to 490W on the +12V rail, with load on the minor rails staying below 90W.

Infrared Images

We apply half-load for 10 minutes with the PSU's top cover and cooling fan removed before taking photos with our modified FLIR E4 camera that delivers 320x240 IR resolution (76,800 pixels).

Temperatures inside of the PSU were normal, meaning that EVGA's SuperNOVA 650 G1+ could have easily supported semi-passive operation.

    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....
