ATX connector limits and cable reach

The 20+4 pin ATX connector works with both 20 pin and 24 pin motherboards. Only one P4 12V 4 pin connector is provided so boards that require an 8 pin EPS cable cannot be powered. Three SATA 15 pin connectors limit the number of SATA drives to three unless splitters are added. Two Molex 4 pin connectors and one floppy 4 pin connector cover legacy peripherals.

Upgrading from a failed or lower wattage unit

This unit replaces a broken or undersized original PSU in the listed HP Pavilion models. The jump is worth it when the existing supply has failed delivers unstable voltage or cannot support added SATA drives. It is not for builders who need more than three SATA devices an 8 pin EPS connector or a higher total wattage than 400W.

Questions about this item

Which Replace Power RPS400-524 capacity suits my HP Pavilion 524c?

The 400W model is the only capacity offered for the RPS400-524 and matches the original HP Pavilion 524c, 533c, 700 CTO, 716n, 743g, 746c and 754n power requirements.

What does the 400W rating deliver inside my Pavilion chassis?

It supplies up to 400W total output through a 20+4 pin ATX connector, a 4-pin P4 12V line, three SATA 15-pin ports, two Molex 4-pin ports and one floppy 4-pin port for drives and peripherals.

How does the 20+4 pin ATX connector work with 20-pin and 24-pin boards?

The 20+4 pin design splits so the same unit fits older 20-pin motherboards and newer 24-pin motherboards without an adapter.
