Compatibility and Protection

This ATX power supply replaces legacy units in the HP Pavilion Elite m9660de desktop. It accepts 115 or 230 V input and provides over current and over power protection. The reduced depth of 5.9 inches height by 3.4 inches width aids installation in tight chassis. High efficiency and low ripple ensure stable delivery.

Builders with standard ATX space.

The unit suits owners of the named HP model seeking a direct replacement with 24-pin ATX, 4-pin P4, three SATA, two LP4 and one floppy connector. It is not for builds that require higher total output or additional PCIe power connectors for modern graphics cards. The single fan provides basic cooling for typical office workloads.

24-pin ATX and 4-pin P4 connector set

The decisive specification is the connector complement: one 24 (20+4) pin ATX, one P4 12 V 4-pin, three SATA 15-pin, two LP4 4-pin and one floppy 4-pin. This matches the original HP m9660de wiring. Verify that your motherboard and drives use exactly these interfaces before purchasing.

Questions about this item

My motherboard uses a 24-pin ATX and a 4-pin P4 connector — will this unit plug straight in?

Yes, it provides a 24-pin ATX connector (20+4) and one P4-12V 4-pin connector for the CPU power socket.

I still have an older hard drive with a Molex power plug and a floppy drive — are those cables included?

The unit includes two LP4 4-pin Molex connectors and one floppy 4-pin connector for legacy drives.

After installation, how can I verify the supply is delivering stable power?

Check that the system powers on reliably, runs without random shutdowns, and that voltages on the +12V, +5V and +3.3V rails stay within normal tolerance under load.
