Nice work on the PSU mod Som! :cool:

Just a quick question, I've been building a custom PSU myself (as you know) but discovered the PSU board was faulty (or i broke it, not sure which :p ) - does it matter which grounds you use for the 5v+, 12v- & 12v+ rails? (cant seem to find any info one way or another)

My other query is how necessary is the sheild to be grounded? My PSU is a pico-psu that is powered by a 12v 10a DC Power brick and so I dont have a ground available.

Thank you, broke your PSU eh you can use whatever ground (black wire) you want without any issue

Yeah that's what I thought too, must have been faulty as there is no obvious damaged parts and no magic smoke escaped when it stopped working.

The ground is not necessary at all so don't worry, it will work fine without it

Yeah that's what I thought, cheers.

Nice work! I must admit I was surprised to see that the aca-12xx cards mounted upside down like that as it's not ideal for Cooling and airflow at all.

Oh wow, you are a lucky boy!

Clear nail polish will do the the trick for those exposed traces.
