260 W ATX Power Supply

The KHACHIMO 510S M420 700-24AGR delivers 260 W of continuous power in a standard ATX form factor. It carries 80 PLUS Gold certification for high efficiency across typical loads. Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency. A 6-pin connector is included for peripheral power.

Zero RPM Fan Mode and LLC Topology

At low and medium loads the cooling fan stops completely for near-silent operation. Resonant LLC topology with DC-to-DC conversion provides clean, consistent power and reduces coil whine. This design also enables more energy-efficient sleep states compared to older group-regulated units. The upgrade is worthwhile when replacing a noisy or less efficient supply in a compact build.

Suited for Efficient Low-Power Systems

This unit suits builders assembling modern standby-capable PCs with modest power requirements. It fits ATX cases where quiet operation and Gold-level efficiency are priorities. Buyers who need more storage or multiple graphics cards should look at something else. Systems requiring higher wattage or additional PCIe connectors are not a match.

Questions about this item

What form factor does this ATX power supply use for mounting?

It uses the standard ATX form factor, so it fits any chassis with ATX mounting holes and the usual rear cut-out.

Which cables must be connected during installation to avoid a no-post fault?

Seat the 24-pin ATX connector and the 6-pin auxiliary connector fully; the step most often missed is the 6-pin plug for CPU power.

How often should the fan be checked once Zero RPM mode stops engaging?

If the fan runs constantly at low load, clean dust from the intake grill and verify the 80 PLUS Gold efficiency rating is still met.
