450W 80 PLUS Gold ITX Flex PSU

The KHACHIMO ENP-7145B is a new 450W ATX power supply built to the ITX Flex 1U form factor. It carries 80 PLUS Gold certification for high efficiency and supports Modern Standby for rapid wake-from-sleep transitions. Resonant LLC topology with DC-to-DC conversion delivers clean power and helps reduce coil whine.

Compact builds needing efficient low-load behaviour

This unit suits small-form-factor systems where a 1U height is required and quiet operation at idle matters. The Zero RPM fan mode stops the fan at low and medium loads for near-silent running. Builders needing higher wattage or a standard ATX footprint should look elsewhere.

Verify 1U clearance and connector fit

Confirm your chassis accepts a 1U high power supply and that the cable set matches your motherboard and component connectors. Ensure the 450W capacity covers the total system draw under full load. Check that the physical dimensions align with your case layout before ordering.

Questions about this item

What motherboard power connectors does the ENP-7145B require to work?

It uses a standard ATX 24-pin main connector and a 4+4-pin CPU power connector, both fixed to the unit.

Will the 39 mm height fit alongside the low-profile cooler I plan to keep in my 1U chassis?

Yes, the 39 mm Flex form factor is designed for 1U racks and leaves room for most low-profile CPU coolers.

How can I confirm the Zero RPM Fan Mode is active after installation?

Under light loads the fan will stay completely still; you can verify silent operation by listening at idle or checking fan speed in BIOS or monitoring software.
