RX580 Power Cable Burnt? I replaced PSU, is my GPU okay?

Edgrd · July 16, 2021

so the title is pretty self explanatory, my psu seems to kill itself and the pcie cable burns itself, i already bought a new PSU which is a coolermaster MWE v2 bronze 550w, my friends seem to say that this psu is atleast okay and miles better than my previous cheap 30$ psu, the real question is has anyone experienced this? will my gpu be damaged too or what?

issue started couple months back, i play some games and PC suddenly goes no signal (or was it no display??) on my monitor, i ignored it and a few weeks ago it got worse so i just straight up turned off the PC and guessed its the PSU, last time it seems fine, then i shut it off, today when im changing psu i just realized it.

P.S some plastic from the PCIe connector seems to be left over on the GPU, can i just replace the power socket? or is my GPU dead?

as is ran ok the last time your gpu is probably fine.

you REALLY want to clean the pcie connector on the gpu thoroughly. having dirt, residue or anyththing in there can cause little arcs that melt the connector (likely what happened before)

any tips on how to clean the gpu power socket as the plastic melts in there? do i just change the power socket or is it okay to just clean it up?

if you are able to and trust yourself soldering tho the pcb you sure can.

i myself wouldn't as i am definetly not skilled enough

as for getting it out, using something thin and hard should do the trick. got a mates old mobo once which 8pin looked the same. was able to clean it out with a thick needle

is asking for problems like this.

If it's not possible to fully fit in the connector into the GPU you get the same issue: the connector gets to hot and melt. The 8 pin connector on the GPU is replaceable and I think that's the best way to solve the problem.

im sorry, when i first bought the psu (a year back i think?) im really tight on money, and its not like saving up for a better psu is easy considering im just a college student, and i also don't have much experience with PCs so i thought any 500W psu should do the trick, seems that i learned the hard way that i was very wrong, haha. the connector itself is fine since its 8 pin just like what the gpu asked for.
