Hello everyone first time posting here.
So, I bought new PSU because my old PSU had 6 pin GPU connector but my GPU (Rx580) needed 8 pins. My new PSU arrived today it's coolermaster mwe 650 80+ bronze. Of course everything was working fine before installing new PSU. I installed the unit tried booting but fans start for a second and then no response. I rechecked all cables for proper connection. Tried bare minimum to boot 1 stick RAM, cpu, and my GPU. Right now I have 2 GPUs older one (1050ti) and newer (rx580) Tried with both GPUs still no success. Tried resetting bios by removing cell from Mobo and holding down power button for 30-50sec to drain all electrical charge. I'll try to plus my old psu now if that works does that mean I got faulty unit? Or I should try something else? I don't have differe Mobo or cpu so can't try with different Mobo.
Update: Tried with old psu everything is working fine. So I guess new PSU is faulty unit. Although when I plugged in new PSU motherboard light was working (it only takes 5v but still...) Any way to know for sure that new PSU is faulty here? Paperclip test will determine that?
Update 2: Tried paperclip tests on both PSUs old one started spinning no problem. New PSU gave one click sound and fan didn't even spin. (This was done on wooden table.) Motherboard was still in case.
Update 3: removed new PSU & installed old one. Now my pc won't boot. I'm back to square one. Fans spin for a sec and then no response. Double checked all cables/connectors, Tried with one ram stick no data and all that. Tried paperclip test on old psu when it was inside case no success. I guess there's some issue with my case grounding and current discharge and all that maybe? Now I'm not even sure if new PSU is faulty or not. What should I do?
Thank you.
