Is a VS550 enough for a GTX 770?

[Xyrophlex]

Recently I've been having issues with my PC where it would randomly restart for no reason. There's no blue screen or warning, it just reboots. I'm currently using a VS550 for a GTX 770 despite the NVIDIA website recommending a 600W power supply, and this worked fine for about a year or so. Could it be, due to old age, that my power supply is no longer up to the task of providing enough power?
My computer can restart without any strain on it and the CPU doesn't seem to have an overheating problem.
Thanks!

VS-series PSUs are extremely unreliable units, meant for office-systems with either no GPU or a very low end one. It is the absolute lowest line in Corsair's lineup. It is a BAD PSU to have in any sort of gaming system.

I definitely recommend a new PSU, preferably a Corsair CX550M or CX650M.

VS are a low quality range with a poor reputation , it’s probably just dying. I would change it before it fails completely and possibly damages other components.

Could very well be the PSU. The VS units use cheaper capacitors and have a low temp rating and the most common indication of them failing is shutting down/restarting, when it it gets hot and or is under load.

Looking at your system specs(from an older thread), the 760g motherboard(if you are still using it) could also be suspect as that weak 4+1 VRM setup could have degraded to the point of no longer being able to handle that 125w cpu. However that problem usually starts out as a performance issue because the VRMs will throttle the cpu to ~1.4Ghz.

Given you have a power hungry cpu with a power hungry gpu powered by fairly poor quality PSU.

I'd try a better PSU first and see if that helps.
