KHACHIMO

KHACHIMO PSR1800-56A ATX power supply

SKU CH-KTJ8-D1RZM

ATX power supply tested working with 1800 W capacity and 56 A on the 5 V rail

  • TypeATX
  • ATX form factor fits standard desktop builds
  • 1800 W output supports high-demand components
  • 56 A on the 5 V rail delivers strong low-voltage power
  • 5 V standby rail enables wake-on-LAN and USB charging
  • Tested working and listed as good quality by the manufacturer

Purpose-built replacement

The KHACHIMO PSR1800-56A is an ATX power supply intended as a direct replacement for the GPR-1800-56AH unit. It suits technicians or system integrators who need a tested, working module to restore power to a compatible chassis.

Verified build and connector fit

Each unit is test-worked before dispatch, confirming basic electrical function and build quality. The ATX form factor and connector layout match the original GPR-1800-56AH, so cable routing and mounting points align with the existing case without modification.

Output ceiling and platform limits

The 1800 W rating and 56 A rail define the practical power ceiling for the connected hardware. Systems demanding sustained draw beyond these figures will exceed the design envelope, and the ATX interface itself cannot deliver higher current without a different platform.

Perguntas sobre este artigo

What ATX power-supply standard does the PSR1800-56A follow and what wattage does that cap it at?

The unit is an ATX-type supply rated for 1800 W, so it conforms to the ATX form factor and delivers up to 1800 watts.

What physical clearance and mounting pattern does the PSR1800-56A need inside a case?

It uses the standard ATX footprint with four rear mounting holes and requires a case that accepts full-size ATX power supplies.

How is the PSR1800-56A installed and which step do builders often miss?

Slide the unit into the case, secure it with four screws, then connect the 24-pin motherboard cable, CPU power cable and any GPU or drive cables — forgetting the CPU power connector is the most common oversight.
