[SOLVED] PC Won't start because of GPU?

[Filip4000]

Today my PC just randomly shut down and won't start up again. I thought it was the psu since I replaced one recently. Turns out it wasn't. My next guess was the power switch not working. The problem was that the pins for the buttons are under my gpu so I had to take it off. I did and I checked the pins with a screwdriver. The computer powered on. So i changed the reset button to be my new power one. I checked and it worked. Next I put in my gpu and nothing. I was very confused. Now it didn't power on even if I took off the gpu. So I unplugged the 24pin and plugged it back in and now it worked again. So I put in my gpu again and still nothing. I have no clue on what could be an issue. I don't see any blown caps on my gpu or mobo.
EDIT: When I press the power button while the gpu is in the gpu fans move very slightly but that's about it.
Specs:
RX 460 2gb Windforce
AMD Athlon X4 840
8gb RAM DDR4
Psu 500w
ASUS A68HM-K MOBO

Can you tell me the specs of your power supply?

Your rx windforce graphics card uses 75w and your atholon uses 65w and your psu is a 500w. You are going to need a better power supply if you want a working computer.

How do i need more than 500? The recommended wattage for my pc is 325.

So your pc was pre-built?

Yep

pre-built computers come with a downside(s). One, all the specs may not be right. Two, faulty wiring. Three, some things may not be compatible.

What are you saying? I haven't changed any components except the psu but I replaced it with the exact same one.

If this is a modular PSU then the pinouts may have changed during production runs or been sourced from another supplier. Never reuse modular PSU cables.

Your PSU image shows 24a on the 12v rail which is only 288w. Subtract 150w for motherbd and cpu leaves you with 138w for the GPU which can use over 150w... that's running too close for comfort IMO.

Perhaps the old PSU had more amps available on the 24v rail?

Doubt it, it did blow up on me but it lasted way longer than the new one, even though this new one still works-ish. I've used the new one for a couple of weeks. The PSU is the issue, I'm 90% sure. Gonna get one tomorrow. Wish me luck. It aint modular btw.
