Server power supply for 12 V loads

The 3Y Power Technology YM-2721A delivers 720 W on a single +12 V rail rated at 58.75 A. Two integrated fans cool the unit in standard server chassis. It suits builds that draw most of their power from the 12 V line.

Practical limits of the 12 V rail

The 58.75 A ceiling means any combination of components must stay below that current on the 12 V rail. Systems needing multiple voltage rails or higher total wattage will require a different power supply design.

Questions about this item

Should I pick the 720 W unit or a lower-wattage model for my server?

Choose the 720 W unit when your build needs up to 58.75 A on the +12 V rail; a lower-wattage model would limit that current headroom.

What does the 58.75 A rating on the +12 V rail mean once the unit is installed?

It means the supply can deliver up to 58.75 A continuously to components that draw from the 12 V line, such as CPUs and GPUs, without exceeding its 720 W total capacity.
