Quote from Tums:
I doubt this machine you recommend has 3 rails.
All power supplies have 3 rails.
But if you were referring to whether or not the +12v rail is single or triple on the 325 watt PSU, you would be correct in assuming that it had a single +12v rail.
The 525 watt that came with my Precision T3400 has triple +12 v rails.
All rated at 18 amps each, I believe.
