2100W ATX Power Supply

The KHACHIMO AHF-2DC-2100W is a new 2100 watt ATX switching power supply designed for systems that demand very high continuous output. It carries 80 PLUS Gold certification and uses a resonant LLC topology with DC-to-DC conversion to deliver clean, consistent power. Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency. Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent operation.

Suited for high-output workstations and servers

This unit suits builders assembling workstations or servers that require a 2100 watt ATX power source with high efficiency and quiet running at typical loads. It is not for buyers who need a lower wattage unit for a standard desktop build, nor for systems that cannot accommodate a 2100W ATX form factor. It also does not fit compact chassis limited to SFX or TFX dimensions.

2100 watt rated output

The single specification that decides fit is the 2100 watt rated output; the platform must be designed to draw and cool that level of power. The 80 PLUS Gold rating confirms high efficiency across the load range, reducing waste heat and noise. Resonant LLC topology with DC-to-DC conversion further supports stable voltage delivery and enables deeper sleep states.

Questions about this item

What motherboard power connectors does the AHF-2DC-2100W require?

The unit is an ATX-type supply, so it needs a standard 24-pin ATX connector plus the usual 4-pin or 8-pin CPU power connector from your motherboard.

Will the 2100W output work with older components that draw less power?

Yes, the Resonant LLC topology with DC-to-DC conversion delivers stable voltage across a wide load range, so legacy parts run normally.

How can I confirm the Zero RPM fan mode is active after installation?

Under light loads the fan stops completely; you can verify by listening for silence or watching the fan blades while the system idles.
