Question Need help with my gpu and my power supply pins that connect to my gpu

[Arismendy]

So I got a a new power supply and I got a redeon 5500 4g gpu and when I connected it to the new power supply it turns on then turns off but I connected back to my old power supply and it worked so I think it’s because the gpu cable is a 8 pin and my old one was 4 pin so what can I do

What is the new PSU?

If it has an 8-pin PCIe or 6+2 PCIe power connector that should work.

If you are using 4-pin to 6-pin or 8-pin adapters, you should not do that.

The psu is a cooler master 600w

Not really specific enough, they have quite a few products that are 600W and none of them are that recent.

The Psu is cooler master 600w lite

That should work, though it is an old unit.

Where did you get the GPU from?

Is there a difference way that I could show the problem to you and you could help like on discord or sum

It is possible your 'new' PSU is many years old and sat on a shelf and it never worked. You say the GPU works with an older power supply, but you mention 4-pin power, which would not apply to any recent GPU (like over a decade). You did not respond to my comment regarding that so it is not clear what your old setup was like and under what circumstances the GPU works.

With what I know so far, either you have purchased a bad PSU, or you are connecting an EPS 12V 8pin or 4+4 pin connector to the 8-pin PCIe GPU connector which should be a 6+2 pin cable coming off the Cooler Master unit. EPS connectors are the ones that plug in near the CPU. But I also don't know what CPU or motherboard you have.

Does the system work with the new PSU but without the GPU installed?
