Compact 1U 100W ATX Power Supply

The KHACHIMO FLXA5101A is a 1U form-factor ATX power supply rated at 100W. It targets builders assembling small form-factor PCs or replacing units in space-constrained chassis where a standard PSU will not fit.

80 PLUS Gold Efficiency

This unit carries 80 PLUS Gold certification, meaning it meets strict efficiency targets at typical loads. That single figure decides whether the PSU matches a build's thermal and energy budget, especially in compact cases with limited airflow.

Standard ATX Installation with Quiet Operation

Installation follows the usual ATX mounting pattern and connector layout, so no special tools or adapters are required. Zero RPM fan mode stops the fan at low and medium loads for silent running, while resonant LLC topology with DC-to-DC conversion reduces coil whine; builders should verify that 100W covers their component peak draw before fitting.

Questions about this item

What does the 100 W rating mean for a desktop build?

It limits the unit to very low-power systems such as thin clients or embedded boards; it cannot support a discrete graphics card or high-wattage CPU.

How does the ATX form factor affect installation?

The supply uses the standard ATX mounting pattern and 24-pin motherboard connector, so it fits any ATX-compatible chassis and board.

What physical space does the 1U height require?

A 1U profile fits in rack-mount or slim enclosures only; verify your case accepts a 1U-high power supply before ordering.
