Dell 960 MT Compatible PSU

This 280 W AT power supply is built as a direct replacement for the Dell 960 MT and compatible part numbers C248C, C5201, C9962 and M8802. It fits a standard ATX mounting pattern with a reduced depth of 5.86" x 3.3" for increased chassis compatibility. An 80 mm fan provides cooling for stable long-term operation.

Sustained Load Behaviour

The unit delivers a continuous total output of 280 W with a peak capacity of 420 W. Output rails include +5 V, -5 V, +12 V1, +12 V2, +3.3 V, -12 V and +5 V standby. Hold-up time is rated at 17 ms at nominal input while rise time stays below 70 ms. Low ripple and noise levels are maintained across the load range and the design has passed Hi-Pot testing.

280 W Continuous Rating Decides Fit

The 280 W continuous rating is the figure that determines whether this unit can support the installed components. Builders needing more sustained power for additional drives or expansion cards should verify their total draw against this limit. The fixed cable set provides one 24-pin (20+4) motherboard connector, one 4-pin CPU connector, three SATA 15-pin connectors, two Molex 4-pin connectors and one floppy 4-pin connector.

Questions about this item

How loud or hot does the 80 mm fan get when the 280 W unit runs all day?

The 80 mm fan is designed for stability and long-life performance, and the supply is Hi-Pot tested with low ripple and noise, so it stays cool and quiet under continuous load.

Which motherboard and drive connectors must my Dell 960 MT already have for this PSU to plug in?

Your board needs a 24-pin (20+4) ATX socket and a 4-pin CPU power header; drives need three SATA 15-pin ports, two Molex 4-pin ports and one floppy 4-pin port.

Will the shorter 5.86-inch depth and AT form factor work alongside the original Dell 960 MT case and mounting points?

Yes — the reduced depth fits the standard ATX slot without extending as far, and the AT design matches the Dell 960 MT mounting pattern.
