  • TypeATX
  • 80 PLUS Gold certified for lower power draw and cooler running
  • Zero RPM fan mode stops the fan completely at low and medium loads for silent operation
  • Modern Standby compatible for extremely fast wake-from-sleep and better low-load efficiency
  • Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power and reduces coil whine
  • 800 W ATX output supports compatible server and workstation platforms

Modern Standby Compatible Power Supply

The KHACHIMO GW-CRPS800 is an 800W ATX power supply built for systems that require fast wake-from-sleep response and strong low-load efficiency. It suits desktop builders and workstation integrators who need reliable power delivery with 80 PLUS Gold certification.

Installation Notes and Common Issues

Standard ATX mounting and connector layout allow straightforward installation in compatible chassis. The unit uses a resonant LLC topology with DC-to-DC conversion, which reduces coil whine, but builders must verify that their motherboard and case support the required power connectors and clearance for this specific form factor.

Sustained Load Behaviour

Under continuous load the 80 PLUS Gold rating ensures high efficiency, lowering power draw and heat output. The Zero RPM fan mode remains off at low and medium loads for silent operation, while the resonant LLC topology maintains clean, consistent voltage regulation during extended use.

Questions about this item

How can I verify the 800W unit is running correctly after installation?

Check that the system posts without shutdowns and monitor the 80 PLUS Gold efficiency rating under typical workloads.

What comes with the GW-CRPS800 and what must I source separately?

The power supply itself is included; all ATX cables are permanently attached so no separate cables are required.

Which of the listed model numbers — NF5270M4M5, SA5212M4, 5212M4, 5280M4 — matches my server?

Compare the exact model code on your existing unit or chassis label to the four codes above; they are not interchangeable.
