Furmark crashes comp but games don't

[nillawafers]

Okay, so I just replaced several parts in my computer.

I went from a C2Q and GTS 250 to a Pentium G3258 and an R9 290x.

I have a Xigmatek 750w PSU that came with the computer when I bought it (second-hand, someone else put it together).

Now, my drivers have been updated, but when I run Furmark at any setting my computer immediately shuts down and reboots.

However, when playing games there aren't any issues...not yet any ways. I've been running Tomb Raider and Assassin's Creed IV for the last few hours and it's fine. No issues with temperatures or anything.

I know that Furmark puts around the maximum possible strain on the GPU, and therefore the PSU.

Should I replace my PSU with a more reliable one? And if so, what should I consider?

Stop using 3dmark. Play games instead of benchmarking all day long..hnn Don't worry about 3dmark , worry if your games work or not, If your games run fine then your video card is fine,,

If Furmark is your only crash experience. Then you can avoid doing anything.

But it does sound like your PSU.

I'd replace it with a good PSU on sale. It can't be more than $40-50 replacement, so definitely worth it in my eyes.

A good time to look for PSU deals as well I guess. To and with Monday.

Would a Corsair TX650 be a good buy?
