650 W ATX PSU for modern PCs

The KHACHIMO C1100 delivers 650 W of continuous power through a standard ATX form factor. It targets builders who want Gold-rated efficiency and quiet operation without over-specifying capacity for mid-range systems.

Gold efficiency with silent low-load running

80 PLUS Gold certification keeps waste heat and fan speed down during typical workloads. A Zero RPM mode stops the fan completely at low and medium loads, while resonant LLC topology with DC-to-DC conversion reduces coil whine and supports modern standby sleep states.

Replaces older bronze or unrated units

The efficiency jump is worthwhile when upgrading from power supplies that lack Gold certification or modern standby support. Systems that stay asleep for long periods benefit most from the faster wake times and lower idle draw.

商品問答

What ATX standard does this 650 W unit meet for modern standby wake times?

It is Modern Standby compatible, delivering extremely fast wake-from-sleep performance and improved low-load efficiency.

What physical space and mounting points does the C1100 require in a case?

The supply uses the standard ATX form factor, so it fits any case with an ATX PSU bay and four rear mounting screws.

Which cables must be connected during installation, and which step is often missed?

Connect the 24-pin motherboard cable, the 8-pin CPU cable, and any GPU or drive cables needed; the step most often missed is fully seating the 24-pin connector until the latch clicks.
