Short version:
I'm looking for the original PSU ratings for each voltage rail, cross load limitations etc for the power supplies that were originally used with the FIC AU31. I know that board was killed by lots of infamous Bestec eMachines computers, so I bet there's lots of people here who might have those PSUs around.
I need a power supply for a very similar board (FIC K7MNF-64) so knowing those amperage values would help identify a good replacement.
==============
Long version:
I recently bought an FIC K7MNF-64 motherboard. This board is very similar to the AU31, in fact the person selling it was advertising it as a replacement for Gateway/HP/etc machines that originally had the AU31 in them.
In my case, I'm using it for a low-budget fix/hotrod of an old MicroATX P3 Dell, and obviously have to replace that power supply (proprietary pinout).
I intended to use an FSP 300W power supply, same as one I use on a full size nForce2 ABit AN7 board. It powers a fully loaded AN7 perfectly, but to my surprise it's slipping against the K7MNF-64.
With just a single 512MB module installed, at 166FSB, and a mobile Thoroughbred that's probably running underclocked, I'm getting these voltages in the bios:
Vcore 1.58
3.3 3.32
5 5.02
12 11.58
Everything's fine except the 12v rail. Technically 11.4v is legal but I don't want it this low. It's only going to get worse when I add load to it.
I do have some AcBel 550W psus that have been discussed in this forum before. They're great for newer boards but last time I tried to use one on my AN7 I ruined the 3.3v supply in about 1 week. The 3.3+5v rating on those AcBels is pretty modest. Maybe it's fine though - I don't know what this board needs. I'd feel better about using the AcBel if I could compare values from the OEM psu for an AU31 (which I don't have).
I looked up the psu from a representative AU31-based emachine, and came up with these part numbers:
eMachines p/n: 100929 (300W psu)
SKU: PWEM100929A3
Can't find anything online that tells the amperage ratings for each rail, or the combined 3.3+5v wattage limit.
I may just throw an AcBel at it and hope for the best, but if somebody has the ratings from an AU31 psu it would be much appreciated.
