Compact ITX Flex Power Supply

The KHACHIMO ITX Flex unit is a DC-to-DC ATX power supply designed for small-form-factor builds that require a 1U footprint. It delivers up to 600 W peak output with a 550 W continuous rating and carries 80 PLUS Gold certification for high efficiency. Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency.

Verify Physical and Electrical Fit

Confirm that your chassis accepts a 1U ITX Flex form factor and that the ATX connector layout matches your motherboard. The DC-to-DC topology with resonant LLC conversion provides clean power and supports deeper sleep states, so ensure your board implements the corresponding power-management features. Zero RPM fan mode activates at low and medium loads, which depends on the thermal profile of your specific configuration.

Ideal for Quiet Small-Form-Factor Systems

This supply suits builders assembling compact workstations or HTPCs who prioritise silent operation and efficient sleep states. It is not intended for full-size ATX cases that expect standard PS/2 dimensions. Buyers who need higher continuous wattage or modular cabling for extensive GPU configurations should look at larger form-factor units.

この商品に関する質問

Does the KHACHIMO ITX FLEX power supply include all necessary cables or must any be purchased separately?

The unit ships as a DC-DC module for 1U S3 chassis; specific cable inclusion is not detailed, so verify with your case or motherboard requirements before ordering.

Should I choose the 550W LMJD-5500 or the 600W LMJD-6000 version for my build?

Select the 550W model for lower peak loads or the 600W model when extra headroom is needed; both share Modern Standby, 80 PLUS Gold, Zero RPM fan mode and LLC resonant topology.

What does the 80 PLUS Gold rating mean for daily power draw and thermals in a compact 1U system?

It guarantees at least 80% efficiency at typical loads, reducing waste heat and allowing the fan to stay off longer via Zero RPM mode, which keeps a small chassis cooler and quieter.
