400W ATX Power Supply

The KHACHIMO P2F-5400V is a 400W ATX switching power supply built for standard desktop builds. It targets system integrators and DIY assemblers who need a tested, working unit for everyday computing tasks. The unit ships new and carries a first-listed date of March 2024.

Standard ATX form factor

This unit follows the ATX form factor so it fits regular desktop chassis and works with mainstream motherboards. It delivers the essential rails a typical board, processor, storage drives and basic graphics card require. Builders gain a straightforward drop-in replacement without specialised cabling or adapter needs.

Sustained 400W output

The supply is rated for 400W continuous output rather than a short peak figure. Under prolonged load it maintains stable voltage across the rails to keep components running without sudden shutdowns. The unit has been test-working to confirm reliable operation during extended sessions.

Questions about this item

How much continuous power can the 400W ATX unit deliver before its protection circuits engage?

The supply is rated for 400 W continuous output, so the first limit you hit under sustained load is that 400 W ceiling.

What noise and heat levels should I expect when the P2F-5400V runs all day?

The unit is tested working and built with good-quality components, so it runs within normal ATX thermal and acoustic limits for a 400 W design.

Which ATX motherboard and CPU power connectors must my system already have for this supply to work?

It uses the standard 24-pin ATX main connector and a 4/8-pin CPU power lead, matching any compliant ATX motherboard.
