Designed for IEI AT P8P9 Systems

The KHACHIMO ACE-916A is a new 200W ATX power supply built for IEI AT P8P9 platforms. It delivers reliable switching power in a standard form factor. The unit targets builders and technicians maintaining compatible industrial or embedded PCs.

Replaces Aging 200W ATX Units

This supply upgrades older 200W ATX units that lack modern efficiency or sleep-state support. The jump is worthwhile when the existing unit struggles with wake-from-sleep reliability or runs loud under light loads. It brings 80 PLUS Gold efficiency and Modern Standby compatibility to compatible chassis.

Standard ATX Fit with Quiet Cooling

Installation follows normal ATX mounting and cabling procedures for the target platform. Zero RPM fan mode eliminates noise at low and medium loads, while resonant LLC topology with DC-to-DC conversion reduces coil whine. Verify connector compatibility with the specific IEI board before fitting.

Questions about this item

Will the 200W ATX unit fit a standard ATX case cut-out?

Yes, the ACE-916A follows the ATX form factor so it mounts in any standard ATX power-supply opening using the usual four screws.

What is the common mistake when installing this PSU in an IEI system?

Forgetting to seat the 20-pin ATX connector and the 4-pin CPU power plug fully; both must click into place before first power-on.

How often should the fan bearing be checked on this 200W model?

The Zero RPM Fan Mode keeps the fan off at low and medium loads, so bearing wear is minimal; a visual dust check once a year is sufficient.
