2400W ATX Power Supply

The KHACHIMO PS-2242-9A delivers up to 2400 watts of continuous power in a standard ATX form factor. It targets high-end workstations and multi-GPU builds that demand sustained output at extreme loads. The unit is supplied new and carries 80 PLUS Gold certification for efficient operation.

Builders needing silent idle and fast sleep wake

Zero RPM fan mode stops the fan completely at low and medium loads for near-silent running. Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency. Systems that require fan airflow at all loads or that cannot use Modern Standby sleep states should consider other designs.

80 PLUS Gold efficiency rating

The Gold certification confirms high efficiency across typical load ranges, reducing power consumption, noise and operating temperatures. Resonant LLC topology with DC-to-DC conversion provides clean, consistent power and reduces coil whine. Buyers who need a different efficiency tier must select an alternative unit.

Questions about this item

Will the ATX form factor fit a standard mid-tower case?

Yes, the ATX type matches the standard mounting pattern used by most mid-tower and full-tower chassis.

Which cables must be connected first during installation to avoid a no-post issue?

Seat the 24-pin motherboard and 8-pin CPU power cables firmly before plugging in any peripheral leads; loose main connectors are the most common cause of a failed first boot.

How often should the fan and interior be cleaned to keep the Zero RPM mode working reliably?

Use compressed air to clear dust from the fan grill and heatsinks every six to twelve months; heavy buildup can prevent the fan from stopping at low loads.
