Is my PSU causing my computer to restart when gaming?

[Thomas Standen]

Hello.

over the past 3 day's my computer has been randomly shutting down during gaming. I have had the same components in my PC for the last 2 years and all has been good.

Here is a quick Screencap from HWmonitor

So I'm thinking either my Graphics card is failing or my PSU is crap. My PSU is a Hiper 625w. Graphics card heatwise seems to be reaching about 60c In game which I don't think is too high. Idle it is about 30c.

I've done a lot of research and I think that maybe I don't have enough watt or vaults (whatever) on the +12v but it has been fine for the last 2 years and I also know that some hardware monitoring software is not always perfect.

Thanks

Tom

Edit: Would a 500watt PSU be ok to do a quick test to check if it is the graphics card?

PSU is shit quality. Get an Antec, Corsair, Seasonic, or XFX PSU that has 500w or greater.

PSU wattage is sufficient, and it's of fairly decent quality (as per Johnnyguru). But PSUs do go bad sometimes, especially over time (and this one doesn't have Japanese caps, making it that bit more likely).
