Compatible Power Adapter

This 135 W AC/DC adapter delivers 19 V at 7.1 A or 19.5 V at 6.9 A. It replaces the original supply for HP Compaq dc7900 8000 Elite Ultra-Slim desktop models including KP722AV, FS489AW#ABA, KR671UT#ABA and SH369UP#ABA. The unit ships with a 10 ft power cord and carries FCC, CE and RoHS certification.

Steady Output Under Load

The adapter maintains its rated 135 W continuously thanks to over-current, over-voltage and short-circuit protection circuits. A smart chip monitors temperature and prevents overheating during extended sessions. High-quality wiring and isolation materials reduce electrical interference while the supply runs at full capacity.

Thermal and Power Behaviour

Safety features include overload protection and over-charge/discharge safeguards that keep the brick running cool in normal use. The 100-240 VAC 50/60 Hz input handles worldwide mains voltage without extra configuration. No moving parts mean silent operation throughout the duty cycle.

Questions about this item

How much heat or noise does the 135 W adapter produce when it runs all day?

The unit has no fan and relies on passive cooling; it stays warm but silent during continuous use.

What must I already own for this 19 V 7.1 A supply to work with my HP desktop?

You need a compatible HP Compaq dc7900 or 8000 Elite Ultra-Slim desktop that accepts a 19.5 V 6.9 A barrel connector.

Will this adapter work alongside the original 592491-001 power supply I kept as a spare?

Yes, both units share the same 19 V / 19.5 V output and 135 W rating, so either can power the desktop interchangeably.
