The correct 310W supply for HP Envy and Pavilion gaming and home towers.

The HP L03980-800 is a 310W internal power supply for HP desktops including the Envy TE01 and Pavilion 690, TP01, TG01 and M01 series. It uses HP connectors and mounting and accepts 100–240V AC input. It suits home users and repair shops replacing a failed HP tower power supply.

Why HP Envy and Pavilion Towers Need an HP Supply

HP Envy and Pavilion towers use proprietary motherboard power connectors. A retail ATX supply will not plug in without adapters and may not fit the case properly.

The L03980-800 is the HP part designed for these systems. It fits the chassis, connects directly and provides the power the original configuration needs, including systems with entry-level graphics cards.

310W for Home and Light Gaming

A 310W rating supports Intel Core and AMD Ryzen processors with the entry-level graphics cards HP offered in these towers, plus drives and peripherals.

Covers Multiple HP Tower Families

Listed for the Envy TE01 and Pavilion 690, TP01, TG01 and M01 series, so one part can service several HP desktops in a household or repair shop.
