Is 1000w PSu enough for 290x crossfire and 3930k ?

[Spook187]

Cutting it close there and we've not had good results with the Corsair units, for example their 1200W Platinum struggles with three cards, whereas other 1200W's like Seasonic, Superflower, Antec don't have an issue.

So I'd say no, go with a 1000W, Gold or higher.

Cheers Gibbo, i suppose i could get another 860i as i have the 900D case, two psu's fits in nice.

Why even bother with hassle they are not that good, sell it and buy a decent 1000-1200 unit (Gibbo even hints above).

How much power would turning HT off save ?

And the psu I've got is the biggest one I can fit in my case lol

Looks like your case has the same PSU limitation as mine (max length 180mm), so a Silverstone Strider 1200W fits in just fine. They were on offer a few days ago, wonder if you could persuade Gibbo to get them on This Week Offer tomorrow?

Could i jump in and say would a corsair 860i with a overclocked i5 3570k at 4.6 with two of these be enough power.

I can definatly tell you no.... I have the same cpu at stock... and I just got 2 x 290 today and it shuts off with a AX860 PSU so 2 x 290x definatly wont work.

Fractal Design Newton R3 1000w Platinum is one hell of a PSU and it's semi passive. The fan only activates when the units delivers more than 700watt.

I got it in my 2nd rig with two pretty OC'ed GTX 780's (1150MHz core /7GHz vram) and a Core i7 3820 OC'ed to 4.6GHz (just testing out atm). And it's all stable. When I get a 4930K for my main rig, I'll install the 3930K into this machine and test further with the wattage usage.

I think you problem lies elsewhere.

1000w is enough, Enermax Platinum are solid units, unless you have a defect.

What is your issue anyway? Does it restart as soon as you apply the overclock or during a certain load time?

Do you have a kill-a-watt?

The 860i is a very good psu, just when i bought it GPU's were not that power hungry as they are now so i may have underestimated the lifespan of power with that psu if i continue with crossfire, only on 7850 CF still and looking at my next upgrade
