800 W ATX workstation power supply

The KHACHIMO Workstation C30 is an 800-watt ATX power supply built for professional workstations. It delivers stable power to demanding CPUs and GPUs while supporting modern sleep states. The unit is supplied new and carries the FSP800-90WSE designation with part numbers 54Y8904 and 54Y8843.

80 PLUS Gold efficiency rating

The single specification that determines suitability is the 80 PLUS Gold certification, which guarantees high efficiency across typical load ranges. This rating means less energy is wasted as heat, resulting in lower electricity draw and reduced thermal output inside the chassis. Builders who need a lower efficiency tier should look elsewhere.

Sustained load behaviour with Zero RPM mode

Under continuous load the resonant LLC topology with DC-to-DC conversion maintains clean, consistent power delivery while suppressing coil whine. At low and medium loads the Zero RPM fan mode stops the cooling fan completely for near-silent operation. The supply also enables Modern Standby for extremely fast wake-from-sleep times and better low-load efficiency.

Questions about this item

How does the 800W rating translate to actual component support in a workstation?

The 800W capacity delivers enough headroom for high-end CPUs and graphics cards in a workstation build, with the LLC resonant topology and DC-to-DC conversion keeping voltage stable under heavy loads.

What does the 80 PLUS Gold certification mean for daily efficiency and heat?

Gold certification means the unit meets strict efficiency targets at typical loads, so it draws less power from the wall, runs cooler, and allows the fan to stay off longer via Zero RPM mode.

Will this ATX power supply fit in a standard workstation chassis?

It follows the ATX form factor, so it mounts in any standard ATX case using the usual four screw holes and clears typical motherboard layouts.
