Compact gold-certified 650W Flex ATX power supply with 39mm depth

KHACHIMO

KHACHIMO 650W 80 PLUS Gold Flex ATX power supply

SKU CH-KE1B-FRB2J

A compact 650 W ATX supply with 80 PLUS Gold efficiency, Flex form factor for small chassis, and a zero-RPM fan mode for silent low-load operation

  • TypeATX
  • Modern Standby support for faster wake times
  • 80 PLUS Gold efficiency reduces power draw and heat
  • Zero RPM fan mode enables silent operation at low loads
  • LLC resonant topology with DC-to-DC conversion delivers clean power
  • Flex ATX form factor fits compact 1U and small chassis

Modern Standby Power Supply

The KHACHIMO 650W Flex ATX unit delivers certified Gold efficiency in a compact form factor. It targets builders assembling small-form-factor PCs, 1U servers or NAS appliances where space is tight and low-load efficiency matters. The Modern Standby compatibility ensures extremely fast wake-from-sleep times for responsive everyday use.

Flex ATX Integration

Designed for Flex ATX chassis and 1U enclosures, the supply fits where standard ATX units cannot. Its resonant LLC topology with DC-to-DC conversion provides clean, consistent power while reducing coil whine. Zero RPM fan mode stops the fan entirely at low and medium loads, freeing the build from audible noise during idle or light workloads.

650W Gold Headroom

The 650W rating and 80 PLUS Gold certification handle mid-range components and multiple drives with comfortable headroom. High efficiency lowers power draw, noise and temperatures across typical loads. Builds demanding sustained output above 650W or requiring standard ATX mounting dimensions will need a larger, differently shaped unit.

Perguntas sobre este artigo

Will the 650 W output hold steady during long gaming sessions without hitting a thermal or protection limit?

The 80 PLUS Gold rating and resonant LLC topology with DC-to-DC conversion deliver clean, consistent power at full load, keeping temperatures lower so the 650 W rating is sustainable.

How loud and hot does the unit get when it runs all day in a small chassis?

Zero RPM fan mode stops the fan completely at low and medium loads, and the Gold-efficient design reduces waste heat, so noise and temperature stay minimal even during extended operation.

Does this Flex ATX supply need a special bracket or cable kit to fit my 1U case?

It uses the standard Flex ATX form factor and ATX power connectors, so it installs directly in compatible 1U or small-form-factor cases without extra brackets or proprietary cables.
