450 W ATX power supply for modern standby PCs

The KHACHIMO Y700 delivers 450 watts through an ATX form factor and carries 80 PLUS Gold certification for high efficiency. Resonant LLC topology with DC-to-DC conversion provides clean, consistent power while reducing coil whine. Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency.

Suited for efficient mainstream builds.

This unit fits builders who want quiet operation and low energy waste in a standard desktop. The zero RPM fan mode stops the fan completely at low and medium loads for near-silent running. Systems that demand more than 450 watts or require multiple high-current connectors should consider a higher-capacity design.

80 PLUS Gold efficiency decides suitability

The Gold rating guarantees high efficiency operation for lower power consumption, less noise, and cooler temperatures across typical loads. This single specification tells you whether the supply meets your efficiency and thermal targets. Buyers who need a different efficiency tier must look at a differently certified model.

Questions about this item

Does the fan need periodic cleaning or replacement on the Y700 450W unit?

The Zero RPM mode stops the fan at low and medium loads, reducing dust build-up and wear, so routine cleaning is rarely required and the fan is not a user-serviceable part.

What limits continuous output on the 450W model?

The 450W rating is the sustained power ceiling; exceeding it triggers over-power protection and the unit will shut down to prevent damage.

How loud and hot does the Y700 get during all-day use?

Zero RPM keeps the fan off at low and medium loads for near-silent running, while 80 PLUS Gold efficiency lowers waste heat so temperatures stay modest even under prolonged operation.
