CRPS 800W server power supply

The KHACHIMO CRPS 800W DPS-800AB-30C is a server-grade power supply built for 1U and 2U rack chassis that accept the CRPS form factor. It delivers 800 watts of continuous output and carries 80 PLUS Gold certification for high efficiency across typical server loads. System integrators deploying dense compute nodes or storage arrays will appreciate the compact redundant design.

Fits CRPS bays with hot-plug support

This unit slides directly into a CRPS-compatible bay and connects through the standard edge connector, so no ATX cable harness is required. Hot-plug capability lets technicians swap modules without powering down the chassis, reducing downtime in multi-node deployments. The resonant LLC topology with DC-to-DC conversion provides clean power rails for sensitive server components.

Modern Standby and Zero RPM fan mode

Modern Standby compatibility enables extremely fast wake-from-sleep transitions and improved low-load efficiency for servers that cycle between idle and active states. Zero RPM fan mode stops the cooling fan entirely at low and medium loads, cutting acoustic noise in office-adjacent rack cabinets. The topology also reduces coil whine and supports deeper sleep states for lower overall power draw.

Questions about this item

How much power can the DPS-800AB-30C deliver continuously under sustained load?

The unit is rated at 800 W continuous output, so it can supply up to that level without shutting down.

How loud or hot does the 800 W supply get when it runs all day?

Zero RPM mode stops the fan at low and medium loads, and the 80 PLUS Gold rating keeps waste heat and noise low during extended operation.

What motherboard connector must my system already have for this ATX power supply to work?

It uses the standard 24-pin ATX main connector plus the usual 4+4-pin CPU and PCIe leads found on modern boards.
