Question about HP ATX-300-12Z, ATX-300-12Z Rev. CDR, HP P/N: 5188-2625, Genuine Bestec 300W PS2 Replacement Power Supp... (ATX30012ZREVCDR) Power Supply
Power supply green light is flashing. What does this mean? ATX-300-12Z Rev. BD
Do yo have a volt meter or an atx psu tester?
you can check voltage to see
If a power supply is bad, your pc will turn off or/and turn on and turn off. As long as your system is running without and shut downs your good.
However if your pc is turing off, I would change it as soon as you can. basically what is happening, when you unplug everything there isn't much of a draw on power so the light remains steady, but when you plug devices in there is a draw and the PSU cannot deliver.
I hope this helps.
