EVGA supernova g2 850w

[Konstantinos Koutse]

hello guys sorry for disturbing you again BUT FINALLY i came to decision to buy this excpensive psu once and for all and get rid of the psu low quality problem! what do you think about it? isi it a good one or should i change my order? will it be able to do crossfire r9 280x? accompanied with a i7 4790k? and also will it be able to support single graphicks cards for the near future?

It'll be a fantastic PSU. It's in tier one of http://www.tomshardware.com/forum/id-2547993/psu-tier-list.html#xtor=EPR-8886. I just bought one of its 750W little brothers.

It's a great PSU, but it might be about 50w low of what we'd like to see for 280xCF. Personally, I'd say it's fine for it. Very hard to find a better platform than the Super Flower [strike]Golden Green[/strike] Leadex platform used in that unit.

+1, it's a very good power supply, with a good warranty. I think an i7-4790k with 2x 280x (plus HDD, DVD, etc) comes out to a little under 700W, so you should be fine.

Very hard to find a better platform than the Super Flower Golden Green platform used in that unit.

According to Tech Power Up's review, it's based on the Leadex platform (which is better)

Yep, my bad. I meant SF Leadex, not Golden green. The B2 is based on the Golden Green.

But your recommendation of below 700w for 280xCF are low according to common doctrine and this:

There's no way that a card that calls for 550-600w for a single card is going to work well with a 700w unit in crossfire. It will certainly run, but the PSU is likely to be at or near capacity any time it's under load, will run hot most the time and will be loud due to full speed fan operation. Having a unit with enough capacity to eliminate any doubt and allow some measure of headroom for cool, quiet operation and efficiency only makes sense.

Plus, if he decides to overclock that CPU, that's a further consideration and an even higher capacity unit might be necessary depending on the severity of the overclock. Same goes for the GPU cards.

RealHardTech recommend 900W. But there's usually a bit of padding in there. I think 850W from a good quality PSU should be OK.

RealHardTech recommend 900W. .

With this they probably consider the cpu too and when using an AMD 8350 for instance might it be necssary,but with the intel used here should he imo be fine.
