PSU To Power Two 3870X2s

post #1 of 15
Thread Starter 
I'm trying to plan an update for my current build that involves two 3870X2s. There's no way that my current PSU could power those, so I'm wondering which PSU I should buy when I go through with the upgrade.

Note: I know the IP35 Pro won't take two 3870X2s and it's going to be replaced.

I haven't looked, but try Newegg /psu /advanced search/ 4x pci-e and you should find something.
Pretty rad setup, what mobo has PCI-E slots spread enough to make 2x work?

Well, since they only take up two slots I was thinking something like this. If I actually go through with this I'll get a 30" monitor that runs at 2560x1600 and have some fun.

I'm still not sure if I want to put $3k down on a gaming rig, because I'm not that big of a gamer. I'd rather be having problems with my PC (and I'm bored right now because it's working perfectly).

Then again, I'd have massive bragging rights.

Silverstone DA850 should give it enough power
post #6 of 15
PC Power and Cooling is my PSU brand of choice, they've been around since PCs were invented pretty much, and also own the popular OCZ power supply brand you might know.

Here's their 860 watt PSU, this'll easily power 2 3870s, along with multiple hard drives, ect.

Lol. My original estimate was off by $70.

That's a PC P&C? It's really short. Not like them at all.

I now have a cooler master real power M1000 in my rig and that has 2 sets of 6 & 8 pin pci-e connectors, plenty of power & connectivity via modular units.

SeaSonic M12 SS-700HM should be more than enough, yet it costs only $179.99 at the egg

I would recommend this;

Linky

Ive got the 850W version, but all the reviews of the 1kW version seem good. Its a fair bit cheeper than the one you suggested. It has 2 8pin and 2 6pin pci-e power connectors. Stability on the antec quattro series is excellent. At load the supplied volts and current doesnt deviate from the atx specification at all in any area. A solid psu.
