Question I need help finding out if it's my PSU or GPU ?

[anrye]

So I got an RX 580 around 3 weeks ago, and it literally is acting like a stubborn child.

It sometimes just doesn't want to startup after a restart, it randomly stutters even when not under load(it takes a few minutes to happen after boot), flashes black and hangs at seemingly random times, etc etc.

If I run a stress test on it, it runs perfectly fine until around the 2 minute mark, then the entire pc just shuts down(Not overheating, I checked with MSI Afterburner and it stays at ~50-60°C). It functions perfectly fine for the first few minutes after a boot, sometimes even lasting for an hour before the problems pop up again.

Thing is, the pc runs perfectly fine on integrated graphics. No problems whatsoever.

I honestly don't know what to do anymore. I've tried:

• Booting into safe mode
• Reseating the GPU
• Resetting CMOS
• Updated BIOS
• Reseated RAM
• Replugging the power connector
• Reinstalled drivers

Specs:
Mobo: ASUS P8H61-M LX
CPU: Intel I5-2400
GPU: AFOX RX 580 8GB
RAM: HyperX 8x2 GB DDR3
PSU: Imperion ATX-500W
SSD: Midasforce 256GB

I would suspect that low end PSU first.

Yeah, me too. But my dad keeps saying it's the Graphics card that's the problem, and I can't test the Power supply because I don't have any money or friends that have a pc.

Such low end PSU most often produce 50% or less of rated power which is always rated as just peak power for short time. Recommenced power for that GPU is (true) 450W , can draw up to 180W alone and PSU ism not one monolith power adapter, it has separate branches for every output and voltage and it may not have enough power on PCIe branch. 180W at 12v means 15Amps. On the sticker you should be able to see how power is divided per branch and or Voltage.
