Target builds

The KHACHIMO LPT47 is an ATX power supply rated at 55W and certified 80 PLUS Gold. It delivers 5V at 5A, 24V at 1.5A and -12V at .7A using resonant LLC topology with DC-to-DC conversion. The unit suits compact or low-power systems that require modern standby support.

Upgrade path

This unit replaces older ATX supplies that lack modern standby compatibility or efficient low-load operation. The jump is worthwhile when a build needs fast wake-from-sleep times, reduced coil whine and a fan that stops completely at low and medium loads. It is not for systems requiring higher total wattage or additional PCIe power connectors.

Practical limits

The 55W ceiling restricts the supply to platforms with modest power draw. The fixed voltage rails of 5V, 24V and -12V limit compatibility with components that demand other voltages or higher current on these rails. Efficiency gains from the 80 PLUS Gold rating diminish as load approaches the maximum rated output.

Questions about this item

What ATX form-factor dimensions does the LPT47 require for mounting?

The LPT47 uses the standard ATX form factor, so it fits any case with an ATX power-supply bay and four rear mounting holes.

How do I enable the Zero RPM fan mode on this unit?

Zero RPM mode activates automatically at low and medium loads; no BIOS or software setting is required, just ensure the fan-control cable is connected to the motherboard header.

When should the internal fan be cleaned or replaced on the LPT47?

Because the fan stops under light loads, dust builds up more slowly; inspect the grill every 12 months and clean with compressed air, replacing the fan only if bearing noise appears.
