250W PSU for Dell Slim Desktops

This replacement power supply delivers up to 250W for Dell Optiplex 390 790 990 3010, Inspiron 530s 540s 545s 546s 560s 570s 580s 620s, Vostro 200s 220s 230s 260s 400s and Studio 540s 537s 560s slim desktop DT systems. It accepts 100-240V AC input at 4.4A and provides 24-pin ATX, 4-pin ATX, SATA and floppy power connectors.

Direct replacement for listed Dell OEM units

The unit matches OEM model numbers including L250NS-00, D250AD-00, PS-5251-08D, H250AD-00, DPS-250AB-67 A and DPS-250AB-73A as well as part numbers such as 7GC81, CYY97 and WX9P8. It is the correct swap when the original PSU in these slim chassis fails or shows instability under load.

Questions about this item

What chassis clearance does the 24-pin ATX connector need on my Dell Optiplex 390?

The unit fits the standard slim-desktop PSU cavity used in the Optiplex 390, 790 and 990; the 24-pin ATX connector aligns with the motherboard header without an adapter.

Which cable should I connect first when installing the 4-pin ATX power lead?

Seat the 24-pin ATX connector fully before plugging the 4-pin ATX power lead; reversing the order can leave the 4-pin partially inserted and cause a no-post condition.

How often should I clean the intake vents to keep the 250W output stable?

Vacuum the front and rear vents every six months; dust buildup restricts airflow and forces the fan to run faster, which reduces long-term reliability.
