So I recently built a new computer mixed some parts from my previous build with some new ones. Today (about 2 days after I built it) I had my computer shut off while I was using it and when it rebooted it gave me the screen saying it had just stopped a power surge.
Mobo- ASUS P8Z77-V
CPU- intel i7 3770k
GPU - XFX Radeon 7970 black edition
Heatsink - Noctua 6 NH-D14
I use a 700w asus PSU (can't say exact model can look up if need be) from my previous build which it worked great on. but now I am wondering if maybe I need to get 800w+ since I haven't really even remotely put any of rig to the test.
A quick estimate of your power needs would put you around 400W total (with overclock). I would think a better PSU like the XFX model would work fine, even a 650W would do (unless you plan on X-fire later).
I don't know that I would replace the PSU just yet although having a backup one on hand probably isn't a bad idea.
I may do crossfire but it won't be in the remotely near future but that leads me into a bit of worry because this PSU was working fine in the other computer which was only roughly 2 years old. I just had the same power surge happen again and I can't seem to find a common factor. I feel I should find the source of the problem before buying new parts
I don't remember who makes Asus PSU's (Asus doesn't), but I don't remember them being very high quality either. That's what worries me. It may not be very old, but if it's a lower quality unit like I believe it to be, it doesn't surprise me at all that it's unstable, at the very least.
