EVGA SuperNOVA 650 G3 PSU Review: Excellence Evolved
Why you can trust Tom's Hardware
Ripple Measurements
To learn how we measure ripple, please click here.
The following table includes the ripple levels we measured on the 650 G3’s rails. The limits, according to the ATX specification, are 120mV (+12V) and 50mV (5V, 3.3V, and 5VSB).
Test | 12V | 5V | 3.3V | 5VSB | Pass/Fail |
---|---|---|---|---|---|
10% Load | 5.5mV | 4.0mV | 4.5mV | 6.5mV | Pass |
20% Load | 8.0mV | 5.6mV | 5.4mV | 8.2mV | Pass |
30% Load | 8.7mV | 5.8mV | 5.7mV | 9.2mV | Pass |
40% Load | 9.3mV | 6.9mV | 6.6mV | 10.7mV | Pass |
50% Load | 10.5mV | 7.5mV | 7.0mV | 12.2mV | Pass |
60% Load | 10.5mV | 8.8mV | 7.9mV | 13.8mV | Pass |
70% Load | 11.1mV | 9.8mV | 9.0mV | 17.0mV | Pass |
80% Load | 11.3mV | 11.1mV | 9.5mV | 18.8mV | Pass |
90% Load | 12.3mV | 11.9mV | 10.6mV | 20.5mV | Pass |
100% Load | 13.1mV | 13.4mV | 12.0mV | 27.5mV | Pass |
110% Load | 14.3mV | 14.5mV | 13.3mV | 30.1mV | Pass |
Cross-Load 1 | 7.5mV | 6.0mV | 7.6mV | 20.2mV | Pass |
Cross-Load 2 | 12.8mV | 12.7mV | 10.6mV | 20.3mV | Pass |
As we've come to expect from Super Flower designs, the 650 G3's ripple suppression is excellent. We did hope for lower ripple at 5VSB, but SF is apparently planning to improve this circuit in the future.
Ripple Oscilloscope Screenshots
The following oscilloscope screenshots illustrate the AC ripple and noise registered on the main rails (+12V, 5V, 3.3V and 5VSB). The bigger the fluctuations on the screen, the bigger the ripple/noise. We set 0.01 V/Div (each vertical division/box equals 0.01V) as the standard for all measurements.

Ripple At 110-Percent Load

bit_user I'm sure it's been said before, but it's worth repeating: SuperNova is a terrible name for a PSU!Reply
A supernova ... is a transient astronomical event that occurs during the last stellar evolutionary stages of a massive star's life, whose destruction is marked by one final titanic explosion.

Co BIY "If you want to install a pair of high-end cards, the SuperNOVA 650 G3 is simply not an option."Reply
Wouldn't 650 watts be too little for a system with two high end cards anyway?
Nvidia recommends 600W for a system with a 1080 Ti in it. -
Aris_Mp You will only have problems if you try to feed 2x VEGA cards with a 650W PSU. The Nvidia high-end cards have low consumption.Reply
this article contains power consumption for all high-end Nvidia GPUs. Another one including AMD ones will be released soon.

gosubuilder I've had this PSU in my build sine around June 2017. Its been solid, haven't had any issues. Its noise isn't as bad as described in this article. I don't think I've stopped once thinking, "damn this PSU is loud" once.Reply -
jpe1701 They stopped putting 2 eps connectors in the 650 g2 as well. Mine came with only one and it was bought just a few months ago. Coincidentally would it be safe to use a splitter on that eps cable or was the original wired with connectors on different wires inside the sleeving?Reply -

LOL I haven't thought of it that way, but Chevrolet sold a lot of Nova cars (started out as the Chevy II in 1962) between 1968 and 1987. They sold 1.7 million between 1968-1974 in 3rd generation alone so the name didn't bother the customer too much.
Anyway I'm assuming the same G3 series that plagued Aris' review of the G3 450 is now okay with the 650.
EDIT: I saw in that original review an update stated that EVGA advised all units since that review are made by SF and not outsourced to RSY. Aris does that mean the first batch of those G3 450s were RSY built?

Maybe b/c regular novas don't produce black holes? Also, not sure how violent they are, as a supernova is thought to be different from novas in more than just scale.20899713 said:20898091 said:I'm sure it's been said before, but it's worth repeating: SuperNova is a terrible name for a PSU!

powernod nice PSU but it's unacceptable for a 650watt PowerSupply to have only 1 EPS connector.(EDIT: BeQuiet's 550watt DarkPowerPro11 has 2-EPS!! https://www.bequiet.com/en/powersupply/611 ) Even older AM3+ motherboards such as the ASUS CrosshairV Formula-Z that my brother has, use an 1x8 & 1x4 ATX12V power connector , so this PSU would be unable to power this kind of mobo!!Reply
Once again, excellent review by @Aris !! The best & most thorough PSU reviewer currently !!
