550W CRPS Power Supply

The KHACHIMO CRPS 550W is an ATX switching power supply built for systems that require the Compact Redundant Power Supply form factor. It delivers 550 watts of continuous power with 80 PLUS Gold certified efficiency for lower energy consumption and reduced heat output. Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency. Resonant LLC topology with DC-to-DC conversion provides clean, consistent power while reducing coil whine.

Ideal for CRPS bays and quiet builds

This unit suits builders fitting a 550W CRPS module into compatible server or workstation chassis that accept the GWCR-550D, GW-CRPS550N or GW-BKPV2CB form factor. The Zero RPM fan mode stops the fan entirely at low and medium loads for near-silent operation. Buyers needing a standard ATX PS2 form factor for a typical desktop case cannot use this unit. Systems requiring power output above 550 watts or a different redundant form factor should look elsewhere.

CRPS form factor decides fit

The single specification that determines compatibility is the Compact Redundant Power Supply form factor identified by the GW-BKPV2CB model designation. This physical and electrical interface must match the chassis power bay exactly. Only proceed if your hardware documentation specifies this CRPS variant.

Questions about this item

What does the 80 PLUS Gold rating on the 550W KHACHIMO CRPS supply mean for daily efficiency?

The 80 PLUS Gold certification confirms high efficiency across typical loads, lowering power draw, reducing heat output and enabling quieter operation.

What physical space does the ATX-type KHACHIMO CRPS 550W unit need inside a case?

It follows the standard ATX form factor, so it fits any chassis with a regular ATX power-supply bay and matching mounting holes.

How is the KHACHIMO CRPS 550W installed, and which cable step do builders often miss?

Mount the unit with four screws, connect the 24-pin motherboard and CPU power cables, then plug in GPU and drive leads; the step most often missed is seating the 24-pin connector fully until the latch clicks.
