KHACHIMO

KHACHIMO FLXA5351A 350W 80 PLUS Gold power supply

SKU CH-F8AK-EB861

80 PLUS Gold 350 W ATX unit with zero-RPM fan mode, Modern Standby support and resonant LLC topology for silent, efficient power

  • TypeATX
  • Modern Standby support gives extremely fast wake-from-sleep and better low-load efficiency
  • 80 PLUS Gold certification delivers high efficiency for lower power consumption, less noise, cooler temperatures
  • Zero RPM fan mode stops the cooling fan at low and medium loads for near-silent operation
  • Resonant LLC topology with DC-to-DC conversion provides clean, consistent power and reduces coil whine
  • 350W ATX power supply in a compact 1U form factor for space-constrained builds

Compact 1U 350W Gold unit

The KHACHIMO FLXA5351A is a 350 watt ATX power supply built in a 1U form factor. It targets small-form-factor builds and embedded systems where space is tight but efficiency matters. The 80 PLUS Gold rating ensures lower heat and reduced energy draw in always-on or sleep-heavy workloads.

Replaces older low-efficiency SFX or TFX units

Swapping out a legacy supply that lacks Modern Standby support or Gold certification cuts idle power and eliminates coil whine. The upgrade is worth it when the system spends long periods in sleep or light-load states and the builder needs silent operation without fan noise.

Delivers 350W continuous for mainstream CPUs

The LLC resonant topology with DC-to-DC conversion keeps voltage stable across the full load range. Zero RPM mode keeps the fan off at low and medium loads. Heavy discrete GPUs or multi-drive arrays will exceed the available headroom.

Perguntas sobre este artigo

What form factor does the KHACHIMO FLXA5351A use for mounting in a 1U chassis?

The unit is a 1U design built to the ATX specification, so it fits standard 1U server or workstation bays that accept ATX power supplies.

Which cable should be connected to enable Modern Standby fast wake on the FLXA5351A?

Attach the motherboard's 5 V standby lead from the main ATX connector; the PSU's Modern Standby circuitry then handles the rapid wake transition automatically.

How often should the fan bearing be checked on the FLXA5351A given its Zero RPM mode?

Because the fan stops at low and medium loads, bearing wear is reduced; a visual dust check once a year during routine system cleaning is sufficient.
