ATX 100W power supply for compact builds

The KHACHIMO GZT-H100S12 delivers 100W of continuous power on a single 12V rail rated at 8.5A. It is an ATX form-factor unit designed for small-form-factor desktops, thin-client replacements or embedded systems that require efficient, low-noise power without the bulk of higher-wattage models.

Standard ATX mounting with modern standby support

Installation follows the usual ATX screw pattern and 24-pin main connector, so it fits existing chassis cut-outs and motherboard headers without adapters. The unit supports Modern Standby, allowing extremely fast wake-from-sleep transitions, and its Zero RPM fan mode stops the fan completely at low and medium loads for near-silent operation.

Check 12V current draw and connector needs

Before ordering, verify that your system's total 12V current demand stays within 8.5A and that the supplied cable set matches your motherboard, CPU and peripheral connectors. The 100W limit makes this unsuitable for builds with discrete graphics cards or multiple drives that would exceed the rated output.

Questions about this item

How do I confirm the 80 PLUS Gold efficiency is active after installing the 100W unit?

Verify the fan remains off during light loads to confirm Zero RPM mode is working, then monitor system stability and wake-from-sleep speed to validate Modern Standby compatibility.

Which cables come with the GZT-H100S12 and what must I source separately?

The power supply ships with fixed ATX cables; check your motherboard and GPU requirements to see if any proprietary connectors or extension cables need separate purchase.

Is the 12V 8.5A 100W model the only capacity offered for this series?

Yes, the GZT-H100S12 is specified as a single 100 watt unit delivering 12 volts at 8.5 amps; no other wattage or current variants are listed for this model.
