NVR, u can use ur current PUS on that board, it WILL work...just dont expect to OC with that MB...

Im using a standard 20-pin ATX PSU, an enermax 465 Whisper series on my MSI Neo 4 Platinum MB and it requires a 24 ATX14V 1.1 connector aswell...u CAN however use a 20 pin also, its just not recomended for OC'n really..

Im running the same 350watt Enermax PSU as u on my MSI Neo 2 PLainum system thats OC'd to 2.75GHz 100% stable on a A64 3000+ Venice...

And my Neo 4 system is at 2.70Ghz...

It can be done, trust me.

I do recomend u get a better PSU thoguh if u plan on running at higher OC speeds.

Ur current Athlon XP Thoroughbred 'B' sucks up more juice than Athlon 64's do. Especialyl now that AMD has gone to 90nm fabrication.
