PC PSU question

Gigachip · 12-28-2012, 08:01 PM

Simple, I did a CPU upgrade on one of my rigs, now I'm wondering about GPU. My intel build is sitting with gtx 670 2 way sli and has a 750w psu
AMD build has 3way hd 7970s crossfire. Would I be able to put the AMD cards into the intel build w/o having to upgrade my PSU or would it it be better to just let stand as is.
If I do decide to put it in the intel build whats recommended PSU?

Best to go to the manufacturer websites and look up the wattage needed.

What is the exact specs of your build? That might help because the PSU powers more than just the GPU and CPU.

AMD-fx 8120
16 gig ram
3 SSD cards 3 HDDs
3 7970s crossfire
1250w PSU

Intel- i7 3770k
8gig ram (going to increase to 32 for fun)
1 SSD 2 HDD
2 GTX 670s
750w PSU

both systems stable.
just figured I can squeeze out more putting the 7970s into the intel build

Why not swap the power supplies.

Definitely let it stand as it is. Those 3 HD7970s in a tri-fire consume a lot of power under full load, and you will be cutting it pretty close if not over what the PSU can provide. Why not just buy a new higher wattage PSU, or switch them around? PSUs are pretty cheap and it seems like you have a lot of money to spend. Also, 32GB of RAM is pointless but it's your money

EDIT: Google "PSU calculator"
