Ruth's sister

Ruth's sister internal power cable 255W 20+4Pin 4 SATA 4 pin CPU

SKU CH-KN8F-FHPW1

A 255W internal power supply with a 20+4 pin motherboard connector, four SATA ports and a 4 pin CPU connector for compatible Dell desktops and servers

  • Delivers 255W to compatible Dell OptiPlex and Precision systems
  • Active PFC corrects input current across 100-240V mains
  • 20+4 pin main connector fits mini motherboard power sockets
  • Four SATA ports power multiple drives from one unit
  • 4-pin CPU connector supplies processor power directly

255 W PSU for GX desktop and server builds

This 255 W internal power supply fits Dell GX980MT, GX760MT and GX960MT chassis. It delivers power through a 20+4 pin motherboard connector, one 4 pin CPU connector, four SATA ports and a floppy drive P4 connector. The unit is non-modular and ships new with 99 % condition.

Active PFC thermals and 100–240 V input

Active power factor correction helps maintain stable output across the 100–240 V input range. The 150 × 97 × 140 mm form factor allows airflow within the original GX enclosures without additional adapters. Power draw stays within the 255 W rating during typical desktop and server workloads.

Replaces L255EM-01 and F255E-00 units

This supply directly replaces part numbers L255EM-01, F255E-00, K340R, 9RD1W and AC255AD-00. The upgrade is worth it when the original unit fails or when a rebuild requires the exact 20+4 pin, 4 pin CPU and four SATA connector layout. It does not serve builds needing a 12 V graphics connector or higher wattage.

Questions about this item

How do I install the 20+4Pin motherboard connector and which step is often missed?

Align the 20+4Pin plug with the motherboard socket and press until the latch clicks; the step often missed is fully seating the separate 4 pin CPU connector near the socket.

What maintenance will the 255W non-modular unit need later?

Dust the intake and exhaust areas regularly; the fixed cables cannot be replaced, so check the 4 SATA and floppy connectors for loose pins during cleaning.

What limit appears first under sustained load on this 255W supply?

The 255W total output ceiling is reached before any single rail limit; Active PFC handles 100-240v input but power draw cannot exceed the rated wattage.
