I just got a new GPU and I blug it in and turn it on and start playing Space Engineers to try it. There is a bright pop from my computer and I smell smoke or burnt something. My question is, is it my GPU or my PSU that blew. I assume that since the card I was getting (Rx 470 4GB) needed 450 watts and my PSU was only 500 my CPU intensive game must have used too much power. Thank you for your answers all help I appreciated.

Specs:
Radeon rx 4350 quadcore (3.8 GHz)
Rx 470 4GB ( Previous card was r7 240)
500 watt PSU
Windows 10

your gpu should be just fine Try to find a 550w or 600w psu your gpu only sustained a loss of power(just like unplugging or flipping your off switch) id assume a cap in your psu blew if you feel confident the psu is blown disassemble it and look for burnt/ chard components.

try booting the pc without the gpu be very careful and have means of containing any spark or flame that may happen. i would assume psu is blown due to the bright pop you explained.

Okay I did that and nothing happened, no led's or any fans moving. So does that mean its my PSU and if so could my GPU be dead somehow as well?

You can inspect each component and look for burn scars, but it's likeliest to have been the PSU. If it were me, I'd start by removing the PSU. If the smell in your case quickly dissipates, but lingers in the PSU, it's probably that. You can try a paper clip test on it if you're comfortable doing so.

Far as damage goes, when a PSU goes they're supposed to sacrifice themselves to protect other components...but that doesn't always happen. The next line of defense is your mobo, and so on to each component.

Thank you very much sir. You've been a lot of help. I am ordering a 700 watt PSU for possible further upgrading and I will go looking around my PSU sometime later tonight. Thanks again.
