Replacement PSU for HP Pavilion Desktops

This Replace Power ATX supply is built as a direct swap for the HP Pavilion DPS-460DB-3A unit used in models H8-1240t, H8-1160t and H8-1050Z. It delivers the same 460 W rating through a standard 24-pin ATX connector, a 4-pin P4-12V plug, three SATA power leads, three LP4 plugs and one floppy connector. The reduced-depth chassis keeps the original fit inside compact HP cases.

Owners of listed HP Pavilion towers needing a new

The unit matches the factory connector layout and physical depth, so it installs without adapter cables or case modifications. Builders assembling a custom system from scratch should look elsewhere, as the shortened housing and fixed cable set limit flexibility in standard ATX enclosures. Buyers who want more storage power leads than the three SATA and three LP4 connectors provided will also need a different design.

Critical spec: 460 W output

This single figure confirms the supply can replace the original DPS-460DB-3A without overloading the HP motherboard or tripping the AC protection. The wide-range input handles both 110 V and 220 V mains at 47 to 63 Hz, while hold-up time of 17 ms and rise time under 70 ms meet the platform timing requirements.

Questions about this item

Will the 24-pin ATX and 4-pin P4 connectors on this 460 W unit plug into my existing HP Pavilion H8-1240t motherboard?

Yes, the unit provides a 24 (20+4) pin ATX connector and a P4 12 V 4-pin connector that match the HP Pavilion H8-1240t, H8-1160t and H8-1050Z motherboards.

How can I verify the power supply is operating correctly once installed?

The unit is Hi-Pot tested with low ripple and noise, a rise time under 70 ms and a minimum hold-up time of 17 ms at nominal input, so stable voltages on the +5 V, +3.3 V, +12 V1, +12 V2, -12 V and +5 V-SB rails indicate correct operation.

Which cables come in the box and what must I source separately?

Included are one 24-pin ATX, one 4-pin P4, three SATA 15-pin, three LP4 4-pin and one floppy 4-pin connector; no additional cables are required for typical HP Pavilion installations.
