Replacement TFX Power Supply for HP Slimline
This new 400 W TFX unit replaces the HP Bestec TFX0220D5WA 504966-001 in slimline and small-form-factor desktops. It upgrades systems originally fitted with 200, 250, 300 or 350 W supplies and delivers 400 W continuous output. An 80 mm double ball-bearing fan provides cooling. Input voltage covers 100/240 V.
AT Standard and Connector Limits
The supply follows the AT type standard and offers a 20+4 pin motherboard connector, a 4-pin CPU connector, two Molex connectors, a floppy connector and two SATA connectors. No other interfaces or power leads are included. Builders needing additional PCIe power, more SATA ports or a different form factor cannot use this unit.
400 Watt Continuous Output
The single specification that determines fit is the 400 W continuous rating, which also reaches a 420 W peak. If the target system requires more than 400 W sustained power, this supply will not meet the demand. Buyers who need higher wattage must select a different model.

Questions about this item
Should I pick the 400 W or the 420 W version?
The supplier title lists 420 W while the specifications state 400 W; the unit delivers 400 W continuous output.
Will the 400 W rating actually run my HP slimline with a discrete GPU?
It provides 400 W steady power through a 20+4 pin motherboard connector, 4-pin CPU connector, two Molex and two SATA connectors for typical slimline builds.
Does the 20+4 pin ATX connector limit me to older motherboards?
The 20+4 pin design fits both 20-pin and 24-pin motherboard sockets, so it works with the HP Bestec TFX0220D5WA 504966-001 platform and similar boards.
