Compact SFX 500W Power Supply

The KHACHIMO SFX unit delivers a rated 500W output with a 600W peak capacity in the small form factor required for mini-ITX and compact builds. It carries 80 PLUS Gold certification for high efficiency and runs on standard ATX power specifications. Modern Standby support enables extremely fast wake-from-sleep times and improved low-load efficiency. The Resonant LLC topology with DC-to-DC conversion provides clean, consistent power while reducing coil whine.

Suitable for Small Form Factor Builds

This power supply suits builders assembling compact systems where an SFX form factor is mandatory and 500W continuous power meets the component demands. The Zero RPM fan mode allows the cooling fan to stop completely at low and medium loads for near-silent operation. It is not for builds that require higher continuous wattage than 500W or systems that only accept full-size ATX power supplies. Buyers needing more connectors or cables than the unit provides should look elsewhere.

80 PLUS Gold Efficiency Rating

The single specification that decides fit is the 80 PLUS Gold certification, which confirms high-efficiency operation for lower power consumption, less noise, and cooler temperatures across typical load ranges. This efficiency level supports the Modern Standby fast wake capability and the Zero RPM fan mode by minimizing waste heat at low loads. Verify that your case accepts SFX dimensions and that 500W continuous power covers your GPU and CPU combined draw before purchasing.

Questions about this item

Should I pick the 500 W or the 600 W version?

There is one unit; 500 W is the continuous rating and 600 W is the peak rating, so you choose this model if your build needs up to 500 W sustained.

What does the 80 PLUS Gold label mean for my PC?

It certifies at least 80 % efficiency at typical loads, which reduces power draw, heat and fan noise compared with lower-rated units.

What ATX standard does this SFX supply follow and what does it cap?

It follows the ATX specification in SFX form factor, capping continuous output at 500 W with a 600 W peak limit.
