800W ATX Power Supply

The KHACHIMO BTX-800SP is an 800W ATX power supply built for modern desktop computers. It carries 80 PLUS Gold certification for high efficiency and lower running costs. Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency. Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power and reduces coil whine.

Builders who want quiet, efficient power

This unit suits builders who prioritise low noise and energy efficiency in a standard ATX chassis. The Zero RPM fan mode stops the fan completely at low and medium loads for near-silent operation. Buyers who need more than 800W of continuous output should look at higher-capacity models instead. Systems requiring redundant or server-grade power supplies will not be served by this single-unit design.

80 PLUS Gold efficiency rating

The 80 PLUS Gold rating confirms the supply meets strict efficiency targets at typical loads, reducing waste heat and electricity draw. This single specification decides whether the unit matches a build's efficiency and thermal requirements. Lower-rated Bronze units run hotter and cost more to operate over time. Higher Platinum or Titanium ratings exist but are not offered by this product.

Perguntas sobre este artigo

How much fan noise and heat does the BTX-800SP produce during all-day operation?

The 800W unit is 80 PLUS Gold certified for high efficiency, runs cooler, and its Zero RPM fan mode stops the fan entirely at low and medium loads for near-silent running.

What connectors must my system already provide for this power supply to work?

The supplier highlights an 8-pin CPU power connector on this ATX-type unit; the 24-pin motherboard lead and any PCIe cables are also required for a complete build.

Will the resonant LLC topology and DC-to-DC conversion work reliably with older motherboards and graphics cards I want to keep?

Yes, the topology delivers clean, consistent power and reduces coil whine, while Modern Standby compatibility supports efficient sleep states on both newer and legacy hardware.
