600W ATX Power Supply for Compact Builds

The KHACHIMO HK700-12UEP is a 600W ATX power supply built in a 2U form factor. It carries 80 PLUS Gold certification for high efficiency and lower heat output. Modern Standby compatibility ensures extremely fast wake-from-sleep times and improved low-load efficiency. Resonant LLC topology with DC-to-DC conversion delivers clean, stable power while reducing coil whine.

Suits Quiet Modern Standby Systems.

This unit suits builders who want near-silent operation thanks to its Zero RPM fan mode that stops the fan at low and medium loads. It fits servers or workstations needing fast sleep recovery and gold-rated efficiency in a compact chassis. Buyers who need higher wattage for multi-graphics-card configurations should look elsewhere. The 2U height also excludes standard ATX tower cases that require full-height units.

600W Output Decides Compatibility

The single specification that decides fit is the 600W rated output. Verify that your complete system draw stays within this limit under full load. The 12V rail delivers the bulk of this power for modern CPUs and graphics cards. If your build demands more headroom, this unit will not be sufficient.

Questions about this item

What motherboard power connectors does the HK700-12UEP require to be present on my board?

The unit is an ATX power supply, so your motherboard must provide a 24-pin main connector and a 4-pin or 8-pin CPU power connector.

Will the 600 W output and Modern Standby support work with an older motherboard that lacks Modern Standby?

Yes, the supply delivers standard ATX voltages and will power older boards normally; Modern Standby features simply remain inactive on platforms without that support.

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

Under light system load listen for the fan — it should stay completely stopped until the internal temperature rises enough to trigger active cooling.
