KHACHIMO 2000W ATX Power Supply CP2000AC54PEZ

2000W ATX Power Supply

The KHACHIMO CP2000AC54PEZ is a 2000W ATX power supply built for high-output desktop systems. It delivers 80 PLUS Gold certified efficiency and supports Modern Standby for rapid wake-from-sleep transitions. The unit uses a resonant LLC topology with DC-to-DC conversion to provide clean, stable power across all rails. It targets enthusiasts and workstation builders who need substantial headroom for multi-GPU or compute-heavy configurations.

Replacing lower-capacity or Bronze-tier units

Stepping up from a lower-wattage or 80 PLUS Bronze power supply becomes worthwhile when the current unit runs near its limit under load, causing fan noise or efficiency losses. The Gold rating and Zero RPM fan mode cut idle power draw and eliminate noise at low and medium loads. The LLC resonant design also reduces coil whine, a common issue in older or budget designs. Systems adding a second high-end graphics card or upgrading to a higher-TDP processor benefit most from the extra capacity and tighter voltage regulation.

Check connector count and case clearance

Verify that the power supply includes enough PCIe and EPS connectors for every graphics card and CPU power socket in your build without relying on adapters. Confirm the physical length fits your chassis, as 2000W ATX units are often longer than standard models. Ensure the motherboard supports Modern Standby if you want the fast sleep-wake behaviour. Builders using compact cases or older motherboards without the required sleep-state support will not gain those specific advantages.
