Which PSU for i5 + GTX 970 (how much W?)

ShakeNBake · 9 Oct 2014 at 16:11

i5-2500k (overclocked)
Single GTX 970 (potentially overclocked)
4 case fans with LED's
2 hard drives, 1 SSD

550W enough, or need more juice?

Corsair or SuperFlower?

Thanks

550w should be more than enough and I would go with Superflower over Corsair any day. The rig in my siggy pulls a max of 420w at the wall while gaming. The Golden Green HX 550w if you don't mind fixed cables. If you want modular though it's going to have to be the Leadex 650w Gold as OCUK doesn't sell any of the smaller capacity modular units which is a big mistake in my opinion.

Just bought a SuperFlower Leadex GOLD 650W and could not be happier with it.

ok thanks guys, I had an eye on that one, reviews look really good for it.

one more question: in HWMonitor, my power readings for CPU are fluctuating quite a lot (1.28-1.32V), despite CPU voltage being set to 1.30V in motherboard BIOS. is this usual, or sign of a power supply that's on its way out? I don't remember seeing this in the past, but maybe an update to HW monitor or something made the readings more accurate?

I have an OCZ PSU, but it was one of the decent ones, I have had it for quite a while now, at least 5 yrs, so just wondering if it would be a good idea to get a new one just to be safe?

Software isn't particularly accurate anyway and I have found HWmonitor to be pretty poor for voltage readings. The only real way to test voltages is with a multimeter.
