Title: 5 HD 7870s
Post by: MZD on December 31, 2013, 02:12:54 AM
Just ordered 5 of these for a sweet price. Now I just need to order everything else.  ;D

What would be the minimum PSU to get to run all five cards? Using online calculators it seems like anything over 800 watts should be enough. Close?

And second, is there any recommended board to use with five cards or will anything with five slots work?

I run 4 7850s off a 760w with plenty of power to spare. I think a good 850W should be good.

Awesome!

Now I just need a cheap mobo to run it on.

Anyone have suggestions for that?

where'd you get them if I might ask?

get a good psu
180 watt * 5 = 900
Evga Supernova 1000w can be had for $130
