TFX power supply for HP Compaq Presario CQ4000KL

This 300 W TFX unit replaces the original power supply in the HP Compaq Presario CQ4000KL. It fits slimline and small form factor chassis that require the TFX footprint. The supply delivers 300 W of continuous power for systems previously equipped with 200, 250, 300 or 350 W units. Builders working on other platforms or larger ATX cases should choose a different form factor.

Sustained 300 W output

The supply is rated for 300 W steady output rather than a short-term peak, so it maintains rated power during extended workloads. An 80 mm cooling fan with double ball bearings provides airflow without the noise penalty of sleeve-bearing designs. Input voltage auto-ranges from 100 to 240 V, allowing worldwide operation without a voltage switch.

Connector complement determines upgrade fit

Included cables are a 20+4 pin motherboard connector, a 4-pin CPU connector, three Molex connectors, a floppy connector and three SATA connectors. If your build needs additional SATA or PCIe power leads beyond this set, this unit will not meet the requirement.
