I have these cards coming in the mail soon and am wondering if I can run 4 of them off my corsair 1000 watt temporally for maybe 2-3 weeks without damaging the psu.

Should work but quad 280x/7970 may exceed the 1000wattage, but it may hold around maybe 1050w

If you watch OC3D Quadfire with 7970 he uses a 1200w power supply from corsair.

If it's to much your computer will just turn off. I can guarantee your going to break 1000w since they have a TDP of 250w each. You might get away with it in light gaming but AAA titles and benchmarks are a no go

Cpu will be at idle and its a haswell pentium, but what I assumed would probably pull 1050 total wattage from the system.

You may be able to run them but you would definitely have to downclock them and lower their vcore.

Get an AX1200i.

How controllable is a haswell pentium? the turbo might kick in to increase the temp/voltagess.

Isn't that darn expensive...but not as expensive as quadfire 7970/280x

I am only running this temporary and already purchased the rm1000 getting another 1350 watt to use as a second psu for the system, but seems I will need to lower voltage and clocks for a bit.

Yes but it's the best 1200 watt PSU you can get.

No it's not. Well as far as 1200w goes yes but there are better cheaper options out there.

Yes it is. Now we can have an argument but it's my opinion so respect it.

I respect opinions but I don't respect it when people just say get item "x" and nothing else because it's my opinion.

I'm assuming you plan to mine with this? You will really want head room and I wouldn't risk it.

Mining eh? Since it will be constantly 250W for each card, you have 1000W there and give other things 100W, just in case, and you're at 1100W. I'd recommend AX1200(i) because a high quality PSU with some headroom is important for the longevity of your mining rig.

Get 3 cards... You're paying too much for a small difference between 3 to 4 cards.

I would just tri-fire them until you can get like a 1200 watt psu :)

The ax1200i is rubbish i know people have had it shut off running 3 titans and 3 290's (not at the same time obviously. A seasonic 1250 or superflower 1300w will be much better and reliable under constant heavy load.

I'm just gonna put 3 in this system for now and the other 2 280x's in my other rig before I get all 7. Then once I get the rest of the cards Run 3 and the system on the 1000 watt then run the other 4 on a 1350 watt psu gives me overclocking room on all the video cards total wattage of the whole system will be around 2100 watts :D. These are not for crossfire btw this rig is for mining.

Can I have the cards in a month after bitcoin mining isn't profitable anymore cause everyone and their mother is jumping on that bandwagon.
