400 W ATX power supply

The KHACHIMO ACE-841AP is a 400 W ATX power supply built for basic desktop systems. It suits office PCs, home builds and light productivity rigs that draw modest power. Tested working and described as good quality, it ships new and ready to install.

400 W capacity and headroom

At 400 W the unit comfortably handles a modern CPU with integrated graphics or a low-power dedicated card. It runs out of headroom once a mid-range or high-end GPU is added, or when multiple drives and expansion cards push sustained draw higher. The design targets standard ATX loads without extra connectors for heavy peripherals.

Upgrade path and when to step up

This supply replaces an ageing or lower-wattage unit in an existing ATX case. The jump is worth it when the current PSU cannot deliver stable power for a new CPU or entry graphics card. Builders who need more storage bays, dual high-power GPUs or sustained loads above 400 W should look elsewhere.

商品問答

Will the ATX form factor of the KHACHIMO ACE-841AP fit my older case and motherboard?

The ATX form factor matches standard case cut-outs and motherboard power connectors used for many years.

How can I verify the 400W ACE-841AP is working correctly after installation?

The unit is test working from the factory; a successful POST and stable operation under load confirm it is functioning as intended.

What cables come attached to the ACE-841AP and what must I source separately?

The power supply ships with its native ATX cables permanently attached; no modular cables are included in the box.
