Direct replacement for HP Slimline

This myVolts TFX power supply replaces the original unit in HP Pavilion Slimline s5371l and s5380t CTO desktops. It delivers 400 W continuous output, upgrading systems that shipped with 200, 250, 300 or 350 W units. The 20+4 pin motherboard connector, 4-pin CPU connector, two Molex, floppy and two SATA connectors match the factory cabling. An 80 mm double ball-bearing fan provides cooling.

Verify TFX fit and connector needs

Confirm the chassis accepts a TFX form-factor supply before ordering. Check that the motherboard uses a 20+4 pin main connector and a 4-pin CPU power connector. Ensure the existing wiring harness reaches the supply mounting position in the Slimline case. The unit operates on 100 to 240 V input without a voltage selector switch.

Two SATA connectors support added drives

The bundled cable set includes two SATA power plugs for SSDs or hard drives. Two Molex connectors and a floppy plug cover legacy peripherals. No modular cables or adapter brackets are supplied, so plan cable routing within the slim chassis. The fixed 80 mm fan exhausts heat through the rear vent.
