Great review by jonnyguru, almost hitting Platinum! Got the XFX 850w Seasonic unit otherwise i would get this.

I thought you got 10 year warranties with 750w+ from EVGA?

The G1 1000W has a 5 year warranty as far as I can see.

Thanks for posting bazpantsphil, looks like a sweet deal :wink:

I've got one of these, they're fantastic PSUs. If anyone has any questions I'd be happy to answer them. :smiley:

850w is way more power than most people (myself included) actually need, but it's nice to know that your PSU won't need upgrading for years and years. If your choice is between this and the G2 I'd say go for whichever is cheaper at the time you're buying, both are "tier 1" PSUs with long warranties (albeit longer for the G2) which are made by very reputable manufacturers (Seasonic and SuperFlower, respectively).

Heat added, OP.

What's a good site to calculate power requirements?

I've never managed to work out which ones are telling the truth; they all seem to come out with different wattages for the same components. If I need to use them, I try several from different reputable brands and take a mean average of their results.

Just Google "PSU calculator" and use a few from reputable companies, such as: Corsair, BeQuiet, Cooler Master, Asus etc.

Or let me know your system specs and I'll let you know if this PSU is up to the task (it probably will be, 850w is way more power than most people will ever need).

:smiley:

EVGA's own one is actually quite good, it's gets quite specific with the components and after trying a few builds on it the results were the same as supposed expert recommendations.

Generally considered a PSU should be should be working at around 60% of rating at max load for best efficiency... you can have more than is good for you :smiley:

Just ordered mine. Hot.

Are the cables fully black? Any ketchup/mustard action going on?

You'll be pleased to hear that the cables are all black with black sleeving and black connectors. The only part which isn't black is white writing on the connectors which says what that cable is for (CPU, SATA, VGA etc). I suspect you could probably remove that with some nail polish remover if you wanted to, though.

You also get loads of cables, I think you get something crazy like five PCI-E power cables, each with two 6+2 pin connectors! I'm not sure what on Earth anyone would be connecting which needs that many PCI-E power connectors, but doesn't exceed 850w.

My only issue with the cables is that they're a bit stiff, but I'm not sure that's an avoidable issue without EVGA including cable mod style individually sleeved cables, which would massively increase the cost of the PSU for no extra performance.

If you don't need this sort of capacity go for the 750w G2. It does edge it, especially the fanless mode.

To require this level of PSU performance, you basically need an overclocked X99 platform and overclocked SLI GTX980's

anyone know why supernova g/p2 psus are seemingly sold out everywhere?

popularity?

The G2 is arguably better built with a better fanless mode. This says fanless but it doesn't really work as well, which isn't a problem but the G2's can stay off for ages even at 350w+ load. It also probably explains why the G2 has a 10 year warranty vs 7 for this.

850w is super overkill for anything but high end multi GPU systems, which is really the only kind of multi GPU system you should have. Good I suppose if you have future upgrade plans.

When I got my GS I used OCCT and Heaven in unison to try and pull as many watts as possible from the wall and I got bored waiting for the fan to turn on. However, I do only have a single GTX 970 and an i5 4690k @ 4.7Ghz, so I don't know how much power I was actually drawing (I don't have a kill-a-watt power meter thingy). Also, I do keep the room my PC is in as cold as possible, I absolutely detest being warm (yeah, I hope today's "lovely weather" sods off sooner rather than later :stuck_out_tongue:...).

At the same price and wattage I'd probably take the G2, if only for the extra 3 years of warranty. However, when it's the same price but the G2 is 100w down, I'm more conflicted. I bought my GS because it was £85 for the 850w, which made the decision easy, but this is more difficult.

That all said, we're really talking about something along the lines of Ferrari or Lamborghini here; both the GS and G2 are leagues ahead of the average PSU and both are more than capable of powering high end systems for years on end with ease.

yeah i meant both, g2 and p2. i found one relatively safe retailer with a p2 and they were charging nearly fifty quid more, whereas other places are expecting stock next week. never seen a psu oos like this, i'm looking to upgrade after nearly 8 years so a bit out of the loop.

The GS, PS (not sure if they're sold in the UK and a bit pointless as the GS nearly achieves 80 Plus Platinum anyway), G2 and P2 (again, generally a bit pointless considering how good the G2 is) are the best high end PSUs for the money. I suspect that's why they're relatively hard to find and are often on back order.

Unless you're desperate to have Corsair Link or happen to find an absolute bargain on another high end PSU, the GS/PS and G2/P2 are most often the best option for most high end systems.

Great psu but same price it's been for months.

A 4690k even with a little volt bump and a GTX970 in an average system, few drives etc will never pull down more than ~400w on extreme stress testing full load. Probably more like under 350w when gaming.

I know that the G2 750w at this sort of load runs fanless all the time at 'normal' environment temps, and around 400w for a PSU like the G2 is also peak efficiency.

Basically even a 750w G2 is waaaaaaaaaaaaaay more than enough for OC GTX970 SLI and a more power consuming platform like X99. People do tend to overestimate their requirements!

If you step up to like X99 + GTX980Ti SLI, then you should certainly think about an 850w though assuming you overclock.

Yes, above comments on power requirements are valid. I am currently using a XFX 550W in my 6700k and MSI R9 390 without any issues even when gaming or OC'd.

The problem/requirement that caused me to order this GS is that I am currently running a 40' 4k monitor and need to connect another 27' for my needs.

At 4k/60Hz DP1.2 has certain limitations which causes resolution and/or refresh rate dropping when a second monitor is connected (even via DVI or HDMI).

Unless or until there are further advancements in DP1.2 or an upgrade to DP1.3 (which I am not banking on, it looks like I will need a second R9 390.

New cards and DP1.3 somewhat immature at this stage Imo. DP 1.2 still not fully refined! Prefer to stick with current gen for now....
