Questions about this item

Which of the listed part numbers — H240EM-00, B240AM-00, B240EM-00, D240ED-00 or H62JR — should I choose for my Dell Optiplex?

All five part numbers refer to the same 240 W unit with a 4+8-pin main connector; pick the one that matches the label on your existing supply.

What does the 240 W rating actually deliver to the system?

The +12 V rails supply 16.5 A and 16 A respectively, plus a 2.5 A standby rail, combining for a total of 240 W maximum output.

What input standard does the supply accept and what does that allow in practice?

It accepts 100–240 V at 50/60 Hz, drawing 3.5 A at 115 V or 2.0 A at 230 V, so it works on mains worldwide without a voltage switch.
