Replacepower 420 Watt universal micro PS3 form factor power supply. This PSU acts as a replacement for several Dell and Lite-On models. It will fit in a standard ATX power supply slot, but just won't extend out as deep as a more traditional ATX PSU . These reduced size PS3 ATX power supplies deliver 420 watts of power. The mounting dimensions are the same as a standard ATX power supply with a reduced depth for increased compatibility and cooling (especially with branded desktops like HPs, Dells, Compaqs, etc). It is cooled by an 80mm fan for stability and long-life performance for years to come. The power supply has cabling built in to give you access to SATA, Molex and Floppy disk drive power connectors, as well as a 20+4-pin motherboard connector, and 4-pin CPU & Dell P6 connector.
This power supply acts as a replacement to many models of PSUs, including the Bestec ATX0300D5WC, HP P/N 585008-001, and more.
