420W TFX Power Supply Upgrade

Suits HP Slimline and SFF Desktops

This unit fits HP VT493AA and HP-D2506R0 models requiring a TFX form factor. It supports systems originally shipped with 200W to 350W power supplies. Builders working with standard ATX chassis or proprietary non-TFX form factors cannot use this power supply.

Peripheral connections include three SATA, two Molex and one floppy connector. Cooling is handled by an 80mm double ball bearing fan inside a 0.6mm SECC case.
