Silver ATX power supply unit with cooling fan and cable bundle

KHACHIMO

KHACHIMO ATX Power Supply 50W 5V 10A 80 PLUS Gold S8JX-G05005C

SKU CH-7AEK-X22GY

ATX power supply delivering 50 W at 5 V with 80 PLUS Gold efficiency, Modern Standby support, Zero RPM fan mode and resonant LLC topology

  • Product typeATX
  • Modern Standby support delivers fast wake-from-sleep with better low-load efficiency
  • 80 PLUS Gold certification lowers power draw, noise and operating temperatures
  • Zero RPM fan mode stops the fan at low and medium loads for near-silent running
  • Resonant LLC topology with DC-to-DC conversion gives clean power, cuts coil whine and enables efficient sleep states
  • ATX form factor fits standard chassis with 50 W output at 5 V 10 A

Purpose and Audience

The KHACHIMO ATX power supply delivers 50 W at 5 V and 10 A for systems that require a compact, efficient source of low-voltage power. It suits builders assembling small-form-factor PCs, embedded appliances, or test benches where a full-sized high-wattage unit would be excessive.

Upgrade Path

This unit replaces older ATX supplies that lack 80 PLUS Gold certification and modern standby support. The jump is worthwhile when you need cleaner DC-to-DC conversion, reduced coil whine, and the ability to enter deeper sleep states without fan noise.

Compatibility Checklist

Verify that your motherboard and chassis accept a standard ATX power supply and that the 5 V 10 A output matches the load requirements of your components. Confirm the physical dimensions fit your case and that the available connectors cover all devices you plan to power.

Questions about this item

Does this ATX power supply fit a standard ATX case cut-out?

Yes, the unit follows the ATX form factor so it mounts in any case with a standard ATX PSU opening using the four rear screws.

Which cables must be connected for a basic Modern Standby build?

Plug the 24-pin ATX connector into the motherboard and the 4-pin or 8-pin CPU power cable into the EPS header; the PSU will then support Modern Standby wake-from-sleep.

How often should the fan be cleaned under typical desktop use?

With Zero RPM mode the fan stays off at low and medium loads, so dust accumulates slowly — a quick blast of compressed air once a year is usually enough.
