Replacement ATX Power Supply

This Replace Power unit is built as a direct replacement for Dell desktop models including the 1100, 2100, 3100, 4100, 4700, 5000, 5100, 5150 and M8805. It fits a standard ATX mounting pattern while using a reduced depth of 5.86 inches by 3.3 inches for wider case compatibility. A single 80 mm fan provides cooling. The supply delivers a total continuous rating of 280 watts with a peak capacity of 420 watts.

Who It Suits and Who Should Look Elsewhere

System builders restoring or maintaining the listed Dell workstations will find the correct connector set and form factor here. The unit includes a 24-pin (20+4) motherboard connector, a 4-pin CPU power connector, three SATA power plugs, two Molex plugs and one floppy power plug. It is not suited for builds that require higher continuous wattage, additional PCIe graphics connectors, modular cabling or a deeper ATX chassis footprint.

Capacity and Headroom

The 280 watt continuous rating comfortably handles typical office desktop loads with integrated graphics, multiple storage drives and standard peripherals. Peak headroom of 420 watts covers short transients during spin-up or boot. Systems with discrete graphics cards, many drives or heavy overclocking will exceed the continuous limit and should select a higher-rated supply.

Questions about this item

Does my Dell chassis need a standard ATX mounting pattern to fit this 5.86" x 3.3" unit?

Yes, it mounts in a standard ATX power supply slot; the reduced depth of 5.86 inches only means it will not extend as far into the case as a traditional ATX PSU.

Can I keep my older IDE hard drive that uses a Molex 4-pin connector?

Yes, the unit includes two Molex 4-pin connectors so an older IDE drive can be powered alongside newer SATA devices.

How can I confirm the +12V1 and +12V2 rails are delivering power after installation?

The system will POST and run stably; the PSU provides +12V1 and +12V2 outputs listed in the specifications, and the 80 mm fan spinning indicates the unit is active.
