SKU CH-E6RE-P38S1

ATX power supply with 80 PLUS Gold efficiency, Zero RPM fan mode, Modern Standby support and compatibility for L220AS-00 and H220NS-00 models

  • Product typeATX
  • Fast wake-from-sleep with Modern Standby support
  • 80 PLUS Gold efficiency lowers power draw and heat
  • Fan stops completely at low loads for silent running
  • LLC resonant topology with DC-to-DC gives clean, stable power
  • 220 W continuous and 460 W peak output capacity

Compatible replacement for multiple OEM units

This KHACHIMO power supply replaces models including L220AS-00, H220NS-00, PS-5221-9, DPS-220UB and FSP220-50SBV. It fits systems originally shipped with 220 W or 460 W OEM units. The ATX form factor allows direct installation in compatible chassis.

80 PLUS Gold efficiency with Modern Standby support

The unit carries 80 PLUS Gold certification for high efficiency at typical loads. Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency. Resonant LLC topology with DC-to-DC conversion provides clean power and reduces coil whine.

Zero RPM fan mode for quiet low-load operation

At low and medium loads the cooling fan switches off entirely for near-silent operation. This suits office PCs and home systems where acoustic comfort matters. Builders needing higher continuous output or non-ATX form factors should look elsewhere.

Questions about this item

Does the 220W ATX unit fit a standard ATX case opening?

Yes, it uses the ATX form factor so it mounts in any standard ATX case cut-out.

What is the first step when installing this PSU, and what mistake do builders make?

Secure the four mounting screws before connecting cables; the common error is plugging cables first and leaving the unit loose.

When should the 80 PLUS Gold certified PSU fan be cleaned or the unit replaced?

Clean the fan intake every six to twelve months; replace the unit if coil whine appears or efficiency drops under sustained 220W load.
