Replacement for Dell PS-5251-5

This TFX power supply delivers 250 W of continuous power and fits Dell systems using the Liteon PS-5251-5 unit. It connects via a 20+4 pin motherboard plug, a 4-pin CPU connector, three Molex, a floppy connector and three SATA leads. An 80 mm double ball-bearing fan handles cooling across the 100 to 240 V input range.

Fits slimline and SFF Dell desktops

The compact TFX form factor suits small-form-factor and slimline Dell chassis that originally shipped with a 200, 250, 300 or 350 W PSU. Builders working in standard ATX cases or needing higher wattage for demanding components should consider other options. The fixed cable set also limits flexibility for custom cable routing.

250 W continuous output

The single figure that decides fit is the 250 W steady-state rating, which matches or exceeds the original unit in compatible Dell models. If the target system requires more power than this rating provides, the supply will not be adequate.
