SKU CH-NSFH-A21Z3

  • 20+4 pin ATX, 4-pin CPU, 2× Molex, Floppy and 2× SATA connectors fit existing builds
  • 80 mm double ball-bearing fan keeps temperatures low

Compatible Dell SFF Models

This TFX power supply replaces the original unit in Dell W208D W209D W210D and TFX025D5WB small-form-factor desktops. It fits the slimline chassis used by those systems and delivers 350 Watt of continuous power for daily workloads.

350 Watt Output Rating

The single figure that decides fit is the 350 Watt rating, which matches or exceeds the 200, 250 and 300 Watt units originally shipped in these Dell models. Builders needing more than 350 Watt should look elsewhere because this unit tops out at that level.

Straightforward TFX Swap

Installation follows the standard TFX form factor: remove the old supply, slide this one in and connect the 20+4 pin motherboard, 4-pin CPU, two Molex, floppy and two SATA cables. The 80 mm double ball-bearing fan handles cooling, but cable routing in tight SFF cases can require patience.
