800W ATX Power Supply for Modern PCs

The KHACHIMO PS-2801-4H-LF delivers 800 watts of continuous power through the ATX form factor. It targets builders who need reliable energy for mid-range components and want certified efficiency. The unit carries 80 PLUS Gold certification for reduced waste heat and lower electricity draw.

Replaces older Bronze or unrated units

Moving up from a lower-efficiency supply cuts power loss at the wall and lets the fan stay off longer under light loads. The jump is worth it when the system spends long periods idle or in Modern Standby sleep, where the Gold-rated platform keeps consumption minimal.

Limited by ATX connector set and fixed cables

The standard ATX layout dictates which motherboards and graphics cards can be powered without adapters. Builders needing extra PCIe plugs for multi-GPU arrays or server-grade EPS connectors must verify compatibility before purchase.

Questions sur cet article

What ATX form-factor dimensions and mounting-hole pattern does the PS-2801-4H-LF use for case fit?

The PS-2801-4H-LF follows the standard ATX form factor, so it fits any case designed for ATX power supplies with the usual four-hole mounting pattern.

What is the correct way to connect the 24-pin ATX and CPU power cables, and which step do builders often miss?

Seat the 24-pin motherboard connector and the 4+4-pin CPU connector fully until each latch clicks; the step most often missed is leaving the CPU power cable unplugged or only partially inserted.

Which component will most likely need attention after several years of continuous operation?

The internal cooling fan is the primary wear item; if it becomes noisy or fails to spin under load the unit should be serviced or replaced.
