Replacement 280 W AC adapter

This 280 W power supply delivers 19.5 V at 14.36 A through a 7.4×5.0 mm centre-pin connector. It is built as a direct replacement for the HP part numbers TPC-CA61 and L00458-002 used with select all-in-one desktops. The unit accepts 100–240 V input at 50–60 Hz and carries CE certification. A matching AC power cord is included in the package.

Suits owners of listed HP all-in-one models

The adapter matches the voltage, current and plug geometry required by the ENVY 32 and ENVY 36 all-in-one PCs as well as systems identified by 2X3J7UTABA, 34-B135SE, HP-TRE 71025 and related part numbers. Buyers whose devices need a different output voltage, a higher current rating or a connector with another diameter should look at alternative power supplies.

Deciding specification: 7.4×5.0 mm centre-pin plug

The barrel connector measures 7.4 mm outer diameter by 5.0 mm inner diameter with a centre pin, and this exact geometry is the single detail that determines physical compatibility. Verify the port on the target machine matches these dimensions before ordering.

Questions about this item

How do I install the 7.4x5.0mm connector on my HP ENVY 32 All-in-One, and what is the common mistake?

Align the centre pin with the socket and push straight in until it seats fully; the mistake is forcing it at an angle, which bends the pin and prevents charging.

What maintenance or replacement will this 280W adapter need over time?

The detachable EU/US/UK/AU power cord is the only user-replaceable part; the sealed adapter body has no serviceable components and is replaced as a unit if output drops below 19.5V 14.36A.

What limit appears first when the adapter runs continuously at 280W?

Sustained 280W output raises internal temperature until thermal protection triggers, causing the unit to shut down until it cools.
