300 W TFX power supply for HP Compaq Presario

This 300 W TFX unit replaces the original power supply in HP Compaq Presario CQ4010TL and CQ4010F desktops. It delivers 300 W of continuous output and fits slimline or small-form-factor chassis. Connectors include a 20+4-pin motherboard plug, a 4-pin CPU plug, three Molex, one floppy and three SATA leads. The 80 mm double-ball-bearing fan provides active cooling.

Sustained-load behaviour with 80 mm fan

The 80 mm double-ball-bearing fan runs continuously to move heat away from internal components during extended use. Rated at 300 W steady output, the supply is designed to maintain that level rather than spike briefly. The manufacturer notes an upgrade path to 420 W for systems that previously used 200, 250, 300 or 350 W units. Input voltage auto-ranges between 100 and 240 V.

Compatibility checks before ordering

Verify that your chassis accepts a TFX form-factor supply and that the 20+4-pin and 4-pin CPU connectors match the motherboard. Count the required Molex, floppy and SATA leads against your drives and peripherals. Ensure the 300 W continuous rating meets the total draw of your installed components. Buyers needing higher sustained wattage or a different physical format should consider other options.

Questions about this item

How loud does the 80 mm double ball bearing fan get when the 300 W TFX unit runs all day?

The 80 mm double ball bearing fan is designed for continuous cooling so the 300 W TFX supply stays stable during extended use.

Which motherboard and drive connectors must my HP Compaq Presario CQ4010 already have for this 300 W replacement to work?

Your system needs a 20+4 pin motherboard socket, a 4-pin CPU socket, three SATA ports and three Molex ports to match the supply’s cables.

Will the 300 W TFX supply fit and power the original components in my CQ4010TL or CQ4010F slimline chassis?

Yes — the TFX form factor matches the slimline case and the 300 W output replaces the original 200, 250, 300 or 350 W unit while keeping the same connectors.
