The power supply is not feeding anything but 12v directly. So incompatibility with sound lies solely on motherboard VRM.

Thanks for replying! So, I shouldn't probably try the 50W unit with my t5720?

T5720 will work with any random 12v power supply of sufficient rating. I power mine from some random HDD box with 4.0A/48W specs.

I must be some kind of standard: the anonymous gangbanger of the 21st century.

Thanks! I'll give mine a try with the 4.16A, 50W then.

Too bad that, like you said, it won't help with the PCI port not working with most sound cards... Maybe there's some pci sound cards that don't need the -12V but I had no luck finding one yet... 🙁

Well you hot glue 12V to -12V module to riser and wire it up to feed -12V to PCI card (probably good idea to check that it is not connected in mobo). I bought such converter but never tries this since my focus sifted to Win98 and then for pure DOS I was planning to get another machine with ISA...

AFAIK T5720 is fully powered by +5v and +3.3v rails.

Are 44pin IDE drives 5v?
