Again I do know that and have tried with both in and get nothing. I only tried with the 24 pin connector to test the psu out to see if it would power on at all. The old old psu is a system builder generic 500w the new one is a gigabyte p650b

So I decided to upgrade my old prebuilt pc. Just adding a graphics card but the psu didn’t have any pci 6+2 connectors so a new psu as well. I get the parts install everything go to turn it on and nothing. No beeps no lights nothing. After an hour or 2 of checking connections and as such I decide to check that I’ve not fried something so reinstall the old psu and everything works fine. I do a paper clip test on the new psu and it works fine. So the psu is not completely dead. So I test a few other things that I can think. if I connect just the 24 pin connector of the old psu to my motherboard and hit the power button I get fans and a power light. If I do the same thing with the new psu I get nothing. System specs im dealing with mother board: msi a68hm grenade cpu: a10 7870k new psu: gigabyte p650b is there anything obvious that I’m missing. Any help would be absolutely amazing.

I know. When I first set the new psu up I connected all power to everything including HDd, optical drive, fans etc. The only reason I mentioned just plugging in the 24 pin plug is because I found it unusual that the old psu would power on with just that plugged in but the new one doesn’t.

If we’re taking about the one next to the power input. Not that obvious
