  • TypeATX
  • Faster wake from sleep with Modern Standby support
  • Lower power draw and cooler running with 80 PLUS Gold efficiency
  • Near-silent operation at low load via Zero RPM fan mode
  • Clean, stable power delivery through resonant LLC with DC-to-DC conversion
  • 800W capacity for dual-CPU and high-end builds

Dual-CPU ATX 800W Unit

The KHACHIMO BTX-800SP is an ATX power supply rated at 800W with an 80 PLUS Gold certification. It includes dual CPU 8-pin connectors, making it suitable for workstations or servers that require two processor power inputs. Modern Standby compatibility allows extremely fast wake-from-sleep times and improved low-load efficiency.

Replaces Standard Single-CPU Units

This unit upgrades systems that previously relied on a standard single-connector PSU when a second CPU socket is populated. The jump is worth it when the build moves to a dual-processor motherboard or when Modern Standby sleep states are required for faster resume. It also supersedes lower-efficiency supplies that lack Gold-rated performance.

Sustained Load Behaviour

Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power during extended operation while reducing coil whine. The Zero RPM fan mode keeps the cooling fan off at low and medium loads for near-silent running. High efficiency maintains lower temperatures and power draw even under continuous demand.

Questions about this item

What form factor does the KHACHIMO BTX-800SP use for case mounting?

The unit follows the ATX form factor, so it fits standard ATX mounting holes and cut-outs in compatible chassis.

Which cables must be connected for dual-CPU power during installation?

Attach both 8-pin CPU power connectors to the motherboard; missing the second connector is the most common oversight on dual-socket boards.

How should the fan intake be maintained to keep Zero RPM mode effective?

Periodically clear dust from the fan grille and intake vents so airflow remains unobstructed when the fan spins up under load.
