myVolts 320 W TFX replacement PSU

This myVolts TFX power supply delivers 320 W of continuous output for the HP Compaq Presario CQ4000KL. It uses the slim TFX form factor and includes a 20+4 pin motherboard connector, a 4-pin CPU connector, two Molex, a floppy connector and two SATA connectors. An 80 mm double ball-bearing fan provides cooling.

Suits owners of the CQ4000KL needing a direct swap

The unit fits the CQ4000KL and other compatible slimline or SFF HP desktops that accept a TFX chassis. It replaces original 200, 250, 300 or 350 W units. Builders using standard ATX cases or systems requiring higher wattage than 320 W should look at a different form factor or capacity.

Check your chassis and connectors before ordering

Confirm the case accepts a TFX-size supply and that the motherboard uses a 20+4 pin main connector with a 4-pin CPU plug. Verify the 100/240 V input matches your mains supply. Ensure the two SATA, two Molex and floppy leads cover all drives and peripherals in the build.
