Dell DCSLF Slimline replacement
This TFX power supply replaces the original unit in Dell DCSLF Slimline desktops and compatible small-form-factor systems. It delivers 250 watts of continuous output for standard office or home configurations. The 20+4 pin motherboard connector, 4-pin CPU connector, three Molex, one floppy and three SATA connectors cover typical internal peripherals. An 80 mm double ball bearing fan provides active cooling.
Installation notes
The TFX form factor fits the existing chassis opening and uses the same mounting points as the factory supply. Cable lengths suit the compact interior, though routing around tight drive cages may require patience. The 20+4 pin plug splits for older 20-pin boards, and the floppy connector remains for legacy devices. Verify that your model accepts a standard TFX depth before ordering.
Sustained-load behaviour
The 80 mm double ball bearing fan maintains airflow during extended operation without the wear common to sleeve bearings. Rated for 250 watts continuous output, the unit handles typical desktop workloads without thermal throttling. Input voltage auto-ranges from 100 to 240 volts for stable delivery across regions. Weighing 3 lb, it stays firmly seated under vibration.
