Hi all,
I received 2 OCZ PSUs and both read nothing on -5V so were sent back - eventually for a refund. I then ordered an Antec EA650 and it had the same reading. I then found a technical page regarding PSU testing that indicated that the -5V is not used on ATX12v PSUs after version 2.01. My questions are thus:
1) How do you know if your mainboard needs the -5V?
2) If needed, how is that supplied to the mainboard in the newer PSU versions if it is not used any longer (e.g. if the original PSU was prior to that version and thus supplied -5v)?
3) Could the newer version then (supposedly better) cause inconsistencies such as USB keyboard and mouse inconsistently functioning, and why would PSU manufacturers create such a problem in the PSU world?
Does anyone have the skinny on the -5V question???
