7970 and cpu requirments for oc

post #1 of 3
Thread Starter 
Ok, I originally bought a msi 7950 twin, which was not not compatible with my gpu water block. Thus, I bought a msi r7970, which has a reference 7970 pcb. My question is will a 550W psu be enough for a oc 7970 and 3570k ?


My exact psu is a KINGWIN Lazer Platinum Series LZP-550 550W.

GPU Link :

I'm fairly confidant my psu can handle a non oc set up, but if I plan to oc a lot on both my cpu and gpu will it be enough?
My psu supposedly can oc to 650W, but will drop to gold efficiency.


My comp specs are as follows:


Asrock extreme4
intel 3570k
msi r7970
256GB 830 Samsung
8 gb of ram
2 corsair 140mm fans
3 gentle typhoons ap-15
1 swiftech mcp655
1 Creative Sound Blaster X-Fi Titanium Fatal1ty Professional
1 Deck keyboard plus razer mouse
1 dvd drive

I also plan to add a fan controller later.

That is one of the best units on the market at that output level, it will comfortably deal with your hardware at Any clocks.

I had this power supply for a short time and can say it can run two 7970s( stock clocks ) with that cpu easliy. Does 650w gold rated.

Might not be healthy to run two 7970s on this psu for long term, but I was just giving the idea that one 7970 and a 3570k is nothing for the unit.
