EVGA SuperNOVA 650 G3 PSU Review: Excellence Evolved

EMC Pre-Compliance Testing

EMC, EMI & EMS Acronyms

Electromagnetic Compatibility (EMC): The ability of a device to operate properly in its environment without disrupting the operation of other close-by devices.

Electromagnetic Interference (EMI): This represents the electromagnetic energy a device emits, which can cause problems in other close-by devices if it is too high.

Electromagnetic Immunity (EMS): Tolerance to electromagnetic emissions.

Equipment & Standards

To properly measure the EMI that a device emits, you need special equipment defined by the CISPR 16-1-1 specification. To learn more about our EMI testing equipment, please check out How We Test Power Supply Units.

In order to minimize EMI noise, some standards have been established. The corresponding standards for Information Technology products are CISPR 32 and its derivative EN 55032. In the EU, every product featuring the "CE" marking has to comply with EN 55032. Both CISPR 32 and EN 55032 divide devices into two classes, A and B. B-class equipment is for domestic environments, so its allowed EMI emissions are significantly lower than for A-class devices.

CISPR 32 / EN55032 Limits
CISRP 32/ EN 55032 Class A Conducted EMI Limit
Frequency of Emission (MHz)Conducted Limit (dBuV)
Quasi-peakAverage
0.15 - 0.507966
0.50 - 30.07360
CISPR 32/ EN 55032 Class B Conducted EMI Limit
Frequency of Emission (MHz)Conducted Limit (dBuV)
Quasi-peakAverage
0.15 - 0.5066 - 5656 - 46
0.50 - 5.005646
5.00 - 30.006050

EMI Results - Average Detector

EVGA's 650 G3 successfully passes the EMI average detector test.

EMI Results - Peak Detector

We observe no problems in the peak detector test.

    I'm sure it's been said before, but it's worth repeating: SuperNova is a terrible name for a PSU!

    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.

    Indeed it is but thankfully those ones have nothing to do with explosions :)

    "If you want to install a pair of high-end cards, the SuperNOVA 650 G3 is simply not an option."

    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.

    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.

    this article contains power consumption for all high-end Nvidia GPUs. Another one including AMD ones will be released soon.

    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.

    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?

    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.

    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!!
    Once again, excellent review by @Aris !! The best & most thorough PSU reviewer currently !!
