Diversification is the natural course for a growing company, especially if they reach the point where they cannot grow any further within their target markets, which often happens when markets become saturated. As you might expect, most of the larger graphics card manufacturers have been trying to diversify into other markets lately, as the profit margins continue to diminish and competition is becoming brutal. A few weeks ago, we had a look at XFX's effort to enter the chassis market with a gaming mid-tower case. Today, we are reviewing EVGA's effort to deliver a high performance power supply, the Supernova 850 G2. This isn't EVGA's first PSU, as they first started shipping PSUs over a year ago, but they're still a relative newcomer to the PSU scene.

While naming a power supply after an exploding star may not be the most sensible choice, the Supernova 850 G2 is based on the very popular Superflower Leadex platform, so we are off to a good start here. It features an 80 Plus Gold efficiency certification and, as its name suggests, the rated maximum continuous power output of this particular model is 850 Watts. Pay attention to the details however, as this unit's maximum power rating is at an ambient temperature of 50 °C. Other notable features of this particular model include an "ECO thermal fan control" and a ten-year warranty, all for $129.99 after rebate. Sounds too good to be true? Read on to find out more about the quality, performance and features of the Supernova 850 G2.

Power specifications (Rated @ 50 °C)
AC INPUT 100 - 240 VAC, 10A, 50 - 60 Hz
RAIL +3.3V +5V +12V +5Vsb -12V
MAX OUTPUT 24A 24A 70.8A 3.0A 0.5A
120W 849.6W 15W 6W

Packaging and bundle

EVGA supplies the Supernova 850 G2 inside a large, aesthetically plain cardboard box. All of the unit's major specifications and features are printed on the rear of the box. The PSU is well protected with a combination of polyethylene foam and cardboard pieces.


Inside the box, we find a bag for the modular cables, five long Velcro strips for cable management, black mounting screws, and a typical AC power cable. EVGA also supplies a jump-start ATX connector that may be used to start the PSU without a motherboard, a perhaps unusual but welcome addition to the bundle of the power supply (this can be useful for doing things like running a Bitcoin ASIC, bleeding a water block, or anything else where you need to power on the PSU without booting a PC).

The Supernova 850 G2 is a fully modular unit, meaning that every single cable is detachable, including the main ATX cable. For improved aesthetics, EVGA ditches the color-coded wires for all-black wires; however, they are not using ribbon-like black cables without sleeving but normal free wires wrapped in black sleeving instead.

    Why are all the diagrams in JPEG format?

    Super Flower and Seasonic get into a PSU fight, who wins?
  • jnkweaver - Friday, May 30, 2014 - link

    It is about a tie. Superflower and Seasonic are both high quality manufacturers. They don't make or market budget supplies.

    Surprise surprise. A superflower-made PSU is "stellar".

    Well no shit.
  • JarredWalton - Friday, May 30, 2014 - link

    Actually, it was more a pun on the "Supernova" being "Stellar". Hahaha....
  • Antronman - Friday, May 30, 2014 - link

    I get it.

    But still...

    The poor kid tries and it just goes right over our heads. :/

    This is the cheapest Leadex 850-Watt PSU on the market. Even cheaper than the SF-branded model. I have a PCP&C Silencer Mk III 850W, which is identical in virtually every way to the EVGA Supernova 850 G2, except PCP&C uses a proprietary circular cable plug.

    The problem is, the PCP&C cost $200, almost double the EVGA, for the same internals.

    PCP&C Silencer Mk III 850W uses the Super Flower Golden King platform, so they are not the same internals.

    "...a weird but welcome addition to the bundle of the power supply (useful for doing things like running a Bitcoin ASIC most likely)."

    To the author, if you don't understand the primary reason for the existence of a jumper for the atx connector I would advise against speculating. Or perhaps spend a few minutes reading through the results of a google search before posting a review article on a topic. After all since you're writing a review on a notable hardware blog we presume you are an authority, such comments as those listed above make some of us question that presumption.
