SKU CH-BWSR-EZCSZ

A 600 W ATX power supply with 80 PLUS Gold efficiency, a 12 V 53 A rail, zero-RPM fan mode and Modern Standby support for fast wake and silent low-load operation

  • TypeATX
  • Faster wake-from-sleep with Modern Standby support
  • 80 PLUS Gold efficiency cuts power draw and heat
  • Fan stops completely at low loads for silent running
  • Resonant LLC plus DC-to-DC delivers clean stable power
  • 12 V rail supplies 53 A for 600 W total output

600 W ATX power supply for modern standby PCs

The KHACHIMO PBA600F delivers 600 W of continuous power through a single 12 V rail rated at 53 A, making it suitable for mainstream desktop builds that require reliable energy delivery. Its ATX form factor fits standard chassis layouts and supports the Modern Standby sleep state for near-instant wake times.

Sustained-load behaviour with LLC resonant topology

A resonant LLC topology combined with DC-to-DC conversion keeps voltage regulation tight during extended workloads, reducing ripple and suppressing coil whine. The design maintains stable output across long sessions rather than only in short bursts, helping protect sensitive components.

Thermals, noise and power draw in normal use

80 PLUS Gold certification confirms high efficiency at typical loads, which lowers waste heat and overall power draw. A Zero RPM fan mode stops the cooling fan completely at low and medium loads, providing near-silent operation until higher temperatures demand active airflow.

Questions about this item

How loud and hot does the KHACHIMO PBA600F get when running all day?

The 80 PLUS Gold certification means high efficiency, so it draws less power from the wall, runs cooler and produces less fan noise. At low and medium loads the Zero RPM mode stops the fan completely for near-silent operation.

What connectors must my motherboard and components already have for this PSU to work?

It is a standard ATX power supply, so your motherboard needs a 24-pin main power connector and a CPU power connector. The unit also provides PCIe connectors for graphics cards and peripheral connectors for drives.

Will the PBA600F work reliably with older hardware I keep in the build?

Yes. The resonant LLC topology with DC-to-DC conversion delivers clean, consistent power and supports modern energy-efficient sleep states, which also benefits older components that expect stable voltages.
