200W ATX Power Supply

The KHACHIMO HK300-11PEP is a 200W ATX switching power supply built for modern desktop systems. It carries 80 PLUS Gold certification for high efficiency operation and lower power consumption. Modern Standby compatibility enables extremely fast wake-from-sleep times. Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power.

Quiet builds and modern sleep states

This unit suits builders who want near-silent operation at low and medium loads through its Zero RPM fan mode. It also supports energy efficient sleep states for compatible platforms. Buyers who need higher wattage for discrete graphics cards or multi-drive arrays should look at higher capacity units instead.

80 PLUS Gold efficiency rating

The Gold certification confirms high efficiency across typical loads, reducing waste heat and fan noise. This single specification determines whether the unit meets your efficiency and thermal targets for a compact or quiet system.

Questions about this item

Will the fan on this 200W unit need cleaning or replacement after extended use?

The fan stops completely at low and medium loads thanks to Zero RPM mode, so bearing wear and dust build-up are reduced compared with a constantly spinning fan.

What limit appears first when this 200W supply runs at full load for long periods?

The 200W maximum output is the hard ceiling; sustained loads above that will trigger protection circuits and shut the unit down.

How much noise and heat does this 80 PLUS Gold unit produce during all-day operation?

At typical loads the fan remains off for silent running, and Gold-rated efficiency keeps waste heat low; only under heavy load does the fan spin up to manage temperature.
