350W ATX Power Supply for Modern Standby Systems

The KHACHIMO MCAT430 delivers 350 watts of continuous power through a standard ATX form factor. It targets builders assembling compact or office PCs that rely on fast sleep and wake cycles. The unit carries 80 PLUS Gold certification for high efficiency across typical load ranges.

Replaces Lower Efficiency or Noisy Units

Swapping out an older supply that lacks Gold-rated efficiency or a semi-passive fan mode reduces heat output and eliminates fan noise at idle. The resonant LLC topology with DC-to-DC conversion also suppresses coil whine, making the upgrade worthwhile when acoustic comfort matters.

Verify ATX Fit and Connector Requirements

Confirm the case accepts a standard ATX power supply and that the motherboard uses a 24-pin main connector plus the necessary CPU and peripheral leads. The 220 V AC input rating suits mains voltage in supported regions.

Questions sur cet article

Will the standard ATX mounting holes and depth fit my mid-tower case?

The unit follows the ATX form factor, so it uses the standard four-screw mounting pattern and depth used by most mid- and full-tower cases.

How do I connect the 24-pin motherboard and CPU power cables, and which step do builders often miss?

Plug the 24-pin connector fully until the latch clicks, then attach the 4+4-pin CPU cable near the socket; the step often missed is seating the CPU power connector completely before routing cables.

When should I expect to replace the cooling fan under normal use?

The Zero RPM mode keeps the fan off at low and medium loads, reducing wear; typical sleeve-bearing fans last several years before noise or failure signals a replacement.
