Hi folks,

I need some help with the DIY home adapter for HP server DPS 800GB A PSU

I look at the diagram located here and internet, and made the short between pin 32 and 33, like pictures i attached. And i made holes in the + and - sections to put a screw and cables with Pci-e conectors.

If i turn on the PSU without cables it goes well, green led turn on and 12v is in the + and - pins

But seems like when i put the screw and the cables, that it make like circuit short, so i take the tester and put the tester cables in +and -, and when the screw is on it, it sounds, like cont. is in it...

I tried with 2 differente PSU new brand, to discard and the same thing, something im doing wrong...

Any idea?



attach 1 nut on the positive  attach 1 nut on the neg

no cable,

turn it on if it runs:

 take 1 pcie you built  and attach  it.


attach the nuts that are furthest apart
