Building my gaming desktop this past few weeks then when I got my psu (LOGISYS Computer PS575XBK 575W ATX12V SLI Ready Power Supply) arrived, hooked up all the cables it worked but while installing OS my desktop turned itself off ,heard a loud bang followed by a smoke I asap removed power cable from the socket and take out the psu which was smells like burnt. I checked the motherboard there is no visible damage that i can see, so I assumed it was the PSU did that. So I bought a better a new PSU(SeaSonic M12II 620 Bronze 620W ATX12V V2.3 / EPS 12V V2.91 SLI Ready 80 PLUS BRONZE Certified Full Modular Active PFC) but when I got the new PSU it did not work at all the fan is not spinning or no lights on the CPU. So I decided to return it as DOA( dead on arrival) and get a replacement . if the PSU did not work again so the problem is the MOBO bec. of what happened ?? I need some ideas guys please help me im really stress and spent a lot of money on this gaming desktop.
