Hey
I recieved my friends old PSU. He said it worked in his old pc but it didnt work in his new build.
He said when he started the new pc with this PSU the fans would start to spin but nothing else would happen.
So i decided to test it because my current PSU is underpowered.
I measured the psu before putting in to my case. All the voltages were right.
So i swapped the psus over and tried to start pc up. All that happened was that the fans started but nothing else happened.
I then stripped all the components off the motherboard except processor and the psu.
Still nothing... Not even the usual beeping wich comes if there is no ram memory and video card.
So I measured the voltages again when the psu were plugged in the motherboard and the computer were turned on. Still the voltages were good. I tried my old psu and the pc booted fine and the damn beeping started so i knew my pc was still alive
What should i check next? Im kinda new to electronics.
