1000W ATX power supply

The KHACHIMO GPSA-1000-48P is a 1000 watt ATX power supply built for desktop PCs that need high, efficient power delivery. It carries 80 PLUS Gold certification and uses a resonant LLC topology with DC-to-DC conversion for stable output. Modern Standby compatibility allows extremely fast wake-from-sleep times and improved low-load efficiency.

Suited for high-performance builds

This unit suits builders who want quiet operation, as its Zero RPM fan mode stops the fan entirely at low and medium loads. It also reduces coil whine for quieter overall performance. Buyers who need a lower wattage unit or a non-ATX form factor should look at other options.

48V rail focus

The model designation highlights a 48 volt rail capability, which is the key specification to verify against your hardware requirements. Ensure your components and motherboard are designed to utilise this voltage delivery.

Questions about this item

What ATX case clearance is needed for the GPSA-1000-48P?

The unit follows the standard ATX form factor, so any case with an ATX power-supply bay will accept it.

Which cables must be connected during installation to enable Modern Standby?

Attach the 24-pin ATX, 4+4-pin CPU and any required PCIe connectors; the firmware then handles the low-power sleep states automatically.

How does the 80 PLUS Gold rating affect long-term dust buildup inside the supply?

Higher efficiency means less waste heat, so the fan runs less often and draws in less dust over the unit's life.
