Compact 200W ATX Power Supply

The KHACHIMO SS-200SU is a 200 watt ATX power supply built for small-form-factor PCs and thin-client workstations. It delivers reliable power for low-draw CPUs and integrated graphics in space-constrained builds. The unit carries 80 PLUS Gold certification for high efficiency across typical loads.

1U Form Factor and Modern Standby Support

Its 1U height allows installation in slim rackmount chassis or compact desktop cases that accept standard ATX connectors. Modern Standby compatibility enables rapid wake-from-sleep transitions and improved efficiency at idle. DC-to-DC conversion on the secondary side provides tight voltage regulation for modern sleep states.

Sustained Load Behaviour and Acoustic Profile

Under continuous load the resonant LLC topology maintains clean power delivery while reducing coil whine. The Zero RPM fan mode keeps the cooling fan off at low and medium loads for near-silent operation. At higher sustained loads the fan engages to maintain safe temperatures without excessive noise.

Questions about this item

How much continuous power can the SS-200SU deliver before it hits its limit?

The unit is rated for 200 W of continuous output, so sustained loads above that level will exceed its design limit.

Does the fan stay on all day or does it stop at low load?

Zero RPM Fan Mode stops the fan completely at low and medium loads, giving near-silent operation until higher loads spin it up.

What motherboard power connector does this ATX supply use?

It uses the standard ATX main power connector, so any motherboard with a matching 24-pin ATX socket will work.
