PC wont turn on anymore with GPU connected

dragoshhh · Feb 13, 2017

So yesterday I was watching a movie on TV and suddenly my computer turned off , I tried turning it on but nothing , so I looked inside and when I was pressing the power button a Led on Ez debug turned red for a millisecond(the +CPU led) , so I started disconnecting some componenys one by one and connecting them again , everything was working until I connected my gpu , when the gpu is connected it wont start not a single fan nothing ,just the red led blinks one time..
Can you guys please help? Whats the problem?

I3 6100
8gb ram hyperx
PowerColor rx460 gpu
Psu: deepcool DE480

psu is suspect

never cheap out on the heart of your pc, hopefully it didnt take parts with it

I was thinking about that , but it worked fine for 4 months ..
Sorry accidentaly voted down your answer

yes it's the PSU, the 12V rail that powers your GPU is bad. Never buy a PSU without some 80+ certificate, even if it's bronze.

np

you get what you pay for

you were lucky to get 4 months with such a low tier psu

those certificates have nothing to do with quality

they are about efficiency

you can get platinum units that blow up after a week

So it's the PSU that causes the problem right?
I'm very low on budget so I'm planning to buy a new PSU : CoolerMaster B500 ver.2

Hold your horses gentleman, of course that PSU can be the reason, but it could also be that the GPU simply died. Before doing anything, I would test the GPU in a different rig if possible, to see if the same thing happens there. If it works, replace the PSU. If not, well... RMA the GPU.

To be perfectly honest though, a PSU replacement would be advised regardless, a better quality model will provide peace of mind and much better reliability. Do not get that Coolermaster, use the following list for reference and aim for a tier 1/2 PSU, potentially even tier 3 if the budget is really scarce:

A quality 450W PSU would be more than enough. I'd get 550W to be future-proof for potential GPU upgrades.

Yes I know.. but the problem is that I live in a small country in Europe, Moldova , and there is no big choice of PSU that I can buy , just : DeepCool dn500 , Cooler Master b500 v2 and b700, Antec VP500P , spire ,xilence and a lot of Chinese shit PSU's.. so I don't know what to buy , the good PSU's are 2 times or even 3 times expensive than normal and I can't afford them right now...

Okay so I figured out that PSU fried my GPU.. because I tried another PSU still no result
So planning to buy a new GPU and PSU that will be a Nvidia GTX 1050 and EVGA 430W
