Hi,
Recently my PC has been restrting during games after I recently built it. My suspicion is that it is my PSU, as I have had no temperature warning from my Graphics Card or elsewhere, so it is not that issue. Is it sensible to assume it is the PSU?
Specs:
i5 4690K un-overclocked
Cpu fan cooler two fans
Sapphire AMD R9 290 Tri X OC
1x SSD
1x7200rpm hdd
2x Case Fan
2x sticks of RAM (8GB)
3x peripherals

Thanks
All feedback is welcome.
 
It could be the PSU, but if it's a new build then obviously there could be other culprits.

Memtest the RAM?
Do you have a spare PSU you could try?
Is the PSU rated for full load?
 
I will be buying a new PSU anyway as I am upgrading my brother's computer and he needs a new PSU for the graphics card. SO I could test that.There is only about 15 W overhead after an upgrade I made, so I highly suspect it is the PSU, just running a stress test whilst changing power options on the GPU.
Will probably run a memtest at some point.
 
Hm, are we talking about complete shutdown just sudden poof and the PC has turned off, or we talking bluescreens and the likes?

Has it happened at Idle/light usage such as youtube?
Any other issues with the PC?
How old is the PSU?

I wouldnt be stress testing with anything too extreme like furmark or combined CPU and GPU tests. 550w is certainly on the low side for your setup when running those kind of torture tests. Stick to benchmarks like valley 4 or the likes.


If Im correct i think that powersupply is a multi rail PSU. Make sure your spreading the load across both rails. Maybe you have the GPU just plugged into one rail and its overloading it at peak causing the shutdowns.

At the moment the PC is just restarting during some moderately high load processes, such as modded Skyrim and DayZ standalone, but never any time else. The PC simply restarts like normal, no BSOD. The power supply is multi rail, I haven't got any daisy chain cables or the likes, so I don't think that is the issue, just two PCIex to the GPU (PSU is modular). The PC and PSU are home made, as of 2 weeks ago, with moderate usage. The time taken to shut down also varies, but not sure why.
 
You're not using a two headed power cable (6 pin and then a 6+2 on the same cable) right? You have two independent power cables from PSU to your gpu right?
 
Yeah
I ordered a new 650W PSU last night as I need a new PSU for an old PC anyway, so I'll check tomorrow.
