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).

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:
