KHACHIMO 400W ATX Power Supply

This KHACHIMO unit is a 400W ATX power supply designed for Pavilion TG01 and TP01 systems. It delivers reliable power for mainstream desktop builds and upgrades. The 80 PLUS Gold certification ensures high efficiency across typical loads. Modern Standby compatibility allows extremely fast wake-from-sleep times.

Compatibility check before ordering

Verify that your chassis accepts a standard ATX form factor power supply. Confirm the motherboard uses the same main power and peripheral connectors as the original PA-3401-2HA unit. Ensure the 400W capacity matches the power draw of your installed components. The unit is intended as a direct replacement for the listed Pavilion models.

Replaces original Pavilion PSU

This supply replaces the factory PA-3401-2HA or L76557-001 unit in compatible Pavilion desktops. The upgrade is worth it when the original unit has failed or when you need Gold-level efficiency and quieter operation. Zero RPM fan mode eliminates noise at low and medium loads. Resonant LLC topology with DC-to-DC conversion reduces coil whine and supports deeper sleep states.

Questions about this item

Does the PA-3401-2HA include power cables or do I need to buy them separately?

The unit ships as the power supply only; standard ATX cables are not in the box and must be sourced separately.

The PA-3401-2HA is built for HP Pavilion TG01 and TP01 chassis; match the model label on your PC to confirm fit.

What does the 400W rating mean when the PC is gaming?

The 400W continuous output delivers up to 400 watts to components; 80 PLUS Gold efficiency keeps heat and fan noise lower under load.
