240W SFF power adapter

The Vszerda 240W unit replaces the original power supply in Dell Optiplex 3040, 3046, 3250, 3650, 3656, 5040 and 7040 Small Form Factor desktops. It accepts 100–127V at 7A or 200–240V at 3.5A at 50–60Hz and delivers up to 240W total output.

Suits SFF Optiplex owners

This adapter fits only the listed Small Form Factor models with matching part numbers such as THRJK, 4GTN5, 4R1KT, D7GX8 and HGRMH. It is not for tower, micro or all-in-one Optiplex chassis, nor for systems that require a different connector layout or higher wattage.

Dual 8-pin and 4-pin SFF connectors

The supply provides one 8-pin ATX power connector and one 4-pin ATX power connector in the Dell SFF pinout. Verify that your motherboard uses this exact two-connector arrangement before ordering.

Questions about this item

How do I install the 8-pin and 4-pin SFF power connectors on the Optiplex 3040 SFF?

Align the 8-pin P1 and 4-pin P2 plugs with the motherboard sockets, press straight in until the latches click, then route cables clear of the CPU cooler. The step often missed is seating both connectors fully before tightening the chassis screws.

Which component will need replacement first on the B240NM-00 unit?

The internal cooling fan typically wears out before the capacitors; expect to replace it after several years of continuous 240W operation.

At what load does the 100-127V 7A input limit appear during sustained use?

Drawing the full 240W max output on a 100-127V supply pushes the 7A input rating, so that limit shows up first under heavy continuous load.
