  • TypeATX
  • Modern Standby support for faster wake-from-sleep times
  • 80 PLUS Gold certified for lower power consumption and cooler running
  • Zero RPM fan mode keeps operation near-silent at low loads
  • Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power

400W ATX Power Supply for Compact Builds

The KHACHIMO JCI-4011PP-1M1 is a 1U form-factor ATX unit rated at 400W. It carries 80 PLUS Gold certification for high efficiency, lower consumption and reduced heat output. Modern Standby compatibility enables extremely fast wake-from-sleep times. Resonant LLC topology with DC-to-DC conversion delivers clean power and supports efficient sleep states.

Suited for Small-Chassis Systems Needing Quiet

This unit fits builders assembling 1U servers, slim workstations or compact desktops where Gold-rated efficiency and silent running matter. The Zero RPM fan mode stops the fan at low and medium loads for near-silent operation. Buyers who need higher wattage for multi-GPU setups or extreme overclocking headroom should look at larger-capacity units instead.

Integrates into ATX Builds with 1U Clearance

The supply slots into any ATX-compatible chassis that accepts a 1U depth, drawing AC power and distributing DC rails to the motherboard, drives and add-in cards. Its DC-to-DC design reduces coil whine and frees up thermal budget inside tight enclosures. Modern Standby support lets the system enter and exit low-power states quickly without extra configuration.

Questions sur cet article

Which motherboard power connector does the KHACHIMO JCI-4011PP-1M1 need to function?

It uses a standard 24-pin ATX connector plus a 4-pin or 8-pin CPU power plug, both required for the supply to deliver its rated 400 W.

Will the 80 PLUS Gold efficiency and Zero RPM fan mode work normally with an older motherboard that lacks Modern Standby support?

Yes, the efficiency rating and semi-passive cooling operate independently of Modern Standby; the fan will still stop at low and medium loads on any compatible ATX board.

How can I confirm the Zero RPM fan mode is active after installing the PSU?

Under light system load the fan should remain completely still; you can also watch for the 80 PLUS Gold efficiency by noting lower wall-power draw versus a non-certified unit.
