1000 W ATX power supply

The KHACHIMO SSP-1000RS delivers 1000 W of continuous power in a standard ATX form factor. It targets desktop builders who need high-efficiency, low-noise operation for modern workstations or gaming systems.

Modern Standby and 80 PLUS Gold limits

Modern Standby support enables rapid wake-from-sleep transitions and improved low-load efficiency, but the motherboard and operating system must both implement the standard to benefit. The 80 PLUS Gold rating guarantees at least 80 % efficiency at typical loads, yet actual savings depend on local electricity cost and system duty cycle.

Resonant LLC topology with DC-to-DC conversion

This topology provides clean, consistent power delivery and reduces coil whine while enabling deeper sleep states. Buyers who require a different internal architecture or who need multiple units for redundant configurations should consider alternative designs.

Questions about this item

Which capacity should I choose between the 850 W and 1000 W versions?

Select the 850 W unit if your build peaks below that level; step up to the 1000 W model when you need more headroom for high-end GPUs or future upgrades.

What does the 80 PLUS Gold rating mean once the unit is installed?

It certifies high efficiency across typical loads, so less electricity becomes heat, the fan can stay off longer, and the system runs cooler and quieter.

How does the ATX form factor limit what I can do with this power supply?

The ATX size fits standard desktop cases and motherboards, so it cannot be used in SFX or TFX chassis that require smaller units.
