300W ATX supply for compact systems

The KHACHIMO Vapel AD301M12-1M1 delivers 300W of continuous power in a standard ATX form factor. It targets builders assembling small-form-factor desktops, office workstations or media centres where modest output and high efficiency matter more than headroom for multiple graphics cards.

Fits standard ATX bays with Modern Standby support

The unit slides into any ATX-compatible chassis and connects via the usual motherboard and peripheral cables. Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency, while Zero RPM fan mode stops the fan entirely at low and medium loads for near-silent operation.

Replaces older bronze or unrated units

Upgrading from a lower-efficiency supply cuts power draw, reduces heat output and eliminates coil whine thanks to the resonant LLC topology with DC-to-DC conversion. The jump is worthwhile when building or refreshing a system that spends long periods idle or in sleep states and values quiet, efficient operation.

Questions about this item

How much continuous power can the AD301M12-1M1 deliver before hitting its limit?

The unit is rated for 300 W of continuous output, so sustained loads above that will exceed its capacity.

Does the fan stay on all day or does it stop when the load is light?

Zero RPM Fan Mode keeps the fan off at low and medium loads, giving near-silent operation until higher demand spins it up.

What motherboard power connector does this 12 V ATX supply require?

It uses the standard 24-pin ATX connector plus the 12 V CPU and PCIe leads that modern motherboards expect.
