myVolts 320W TFX Power Supply for HP PC8044 504965-001

HP PC8044 Compatible TFX PSU

This 320 W TFX power supply is built to replace the original unit in the HP PC8044 504965-001 small-form-factor desktop. It delivers 320 W of continuous power through a 20+4 pin motherboard connector, a 4-pin CPU connector, two Molex, one floppy and two SATA leads. The 80 mm fan handles cooling inside the slim chassis.

Before ordering check your build

Verify that your HP desktop uses the PC8044 or 504965-001 part number and that the case accepts a TFX form-factor supply. Confirm the existing unit is rated at 200, 250, 300 or 350 W so the 320 W replacement matches or exceeds the original output. Ensure the motherboard requires a 20+4 pin main connector and a 4-pin CPU connector and that your drives use Molex, floppy or SATA power. The input range covers 100 to 240 V for worldwide mains compatibility.

Upgrade from lower-wattage TFX units

This supply replaces 200, 250, 300 or 350 W TFX power supplies in the supported HP models. The jump is worth it when the original unit has failed, when added peripherals demand more headroom or when a higher-wattage 420 W upgrade is not required. It restores reliable power delivery without changing the chassis or cable routing.
