I'm trying to upgrade the PSU in my Optiplex 9020 so that i can run a better GPU. I bought a Corsair VS550 and the Moddiy adapter (www.moddiy.com/.../Dell-OptiPlex-9020-PSU-Main-Power-24%2dPin-to-8%2dPin-Adapter-Cable-(30cm).html) which was recommended in this forum.
With everything plugged in, the PSU won't turn on. I tested the PSU with the paperclip test, and it seems to be running fine. Is it possible that the adapter is broken?
Any one else struggle with the adapter?
Any help would be much appreciated.
I know from experience that psu adapters are not very reliable, and really should be temporary, as they tend to fail a lot, however not working out of the box is rare. One thing you could try is, well not ideal, however you could run the original psu to your mother board and cpu, then mount your second psu and use that for your gpu. (make sure you are plugging in the molex end of the adapter) p.s. why couldn't dell just use a 24 pin like everyone else.
Please try with different adapter since Corsair PSU is working fine.
