Questions about this item

Should I pick the 650W unit or a different wattage for my switch?

The PSR650B-12A1 delivers 650W total with 12V at 52.9A and 5Vsb at 3A, matching the spec for listed HP 5800, 5900, 5820AF-24XG, 5920AF-24XG and A5830AF-48G switches.

What does the 650W rating actually provide inside the chassis?

It supplies up to 650W continuous, with the 12V rail capable of 52.9A and the 5V standby rail providing 3A for management functions.

Is the 80+ Silver efficiency tied to a specific input range?

The unit accepts 100-240V at 50-60Hz and draws 10-5A, so the 80+ Silver rating applies across that full worldwide input range.
