TFX 250 W replacement for Dell N038C SFF

This TFX form-factor unit delivers 250 W of steady power and fits Dell N038C slimline and SFF desktops. It accepts 100 to 240 V input and provides a 20+4 pin motherboard connector, a 4-pin CPU connector, three Molex, a floppy connector and three SATA connectors for a wide range of peripherals.

80 mm double ball-bearing fan cooling

An 80 mm fan with double ball bearings handles airflow without a passive design. The supply weighs 3 lb and measures 3.258 by 6.877 by 2.258 in, matching the original chassis clearance. Steady 250 W output keeps older systems and custom builds stable under normal loads.

Connectors cover legacy and modern drives

Three SATA connectors support current SSDs and hard drives while three Molex and a floppy connector serve older devices. The 20+4 pin and 4-pin CPU plugs ensure motherboard compatibility. Builders who need higher wattage than 250 W or additional PCIe power for discrete graphics cannot use this unit.

Questions about this item

How do I install the 20+4 pin motherboard connector and which step do people often miss?

Align the 20+4 pin connector with the motherboard socket and press firmly until the latch clicks; the step people miss is fully seating the 4-pin CPU plug so it locks in place.

What maintenance will the 80mm double ball bearing fan need later?

The double ball bearing fan is sealed and requires no lubrication; only occasional dust removal from the fan blades and vents is needed.

At what load does the 250W limit show up first under sustained use?

The 250W steady output limit is reached when combined component draw approaches 250W, causing the unit to shut down or throttle to protect the system.
