800W ATX Power Supply for Modern PCs

The KHACHIMO DPS-800QB A 856-851445 delivers 800 watts of continuous power in a standard ATX form factor. It is built for desktop builders who need reliable energy delivery for mid-range to high-performance components. The unit supports Modern Standby for extremely fast wake-from-sleep times and improved low-load efficiency.

Efficiency Limits of 80 PLUS Gold

An 80 PLUS Gold rating guarantees at least 80 percent efficiency at typical loads, reducing waste heat and lowering electricity draw. The resonant LLC topology with DC-to-DC conversion maintains tight voltage regulation across varying demands. This design also enables deeper, more energy-efficient sleep states supported by modern operating systems.

Quiet Build with Zero RPM Mode

A Zero RPM fan mode stops the cooling fan completely at low and medium loads, providing near-silent operation during everyday tasks. The resonant LLC topology further reduces coil whine for a quieter acoustic profile. Standard ATX mounting ensures compatibility with typical chassis layouts for straightforward installation.
