KHACHIMO Z2 800 880 G4 G5 G6 4Pin 550W power supply

ATX 550 W Gold power supply

The KHACHIMO Z2 550 W unit is an ATX power supply built for desktop PCs that need reliable, efficient power delivery. It carries 80 PLUS Gold certification and uses a resonant LLC topology with DC-to-DC conversion for stable output. Modern Standby support allows extremely fast wake-from-sleep times and better low-load efficiency. A zero-RPM fan mode keeps the system near-silent at low and medium loads.

Check ATX fit and connector needs

Before ordering, verify that your case accepts a standard ATX power supply and that your motherboard uses a 24-pin ATX power connector. Confirm the CPU power requirement matches the available 4-pin or 8-pin EPS connector on the unit. Ensure the graphics card power connectors supplied meet your GPU's needs. Check that the physical dimensions suit your chassis clearance.

Replaces older Bronze or unrated units

This supply replaces older 80 PLUS Bronze, White or unrated ATX units when you want higher efficiency, lower heat and quieter operation. The jump is worth it if your current PSU lacks Modern Standby compatibility or runs its fan constantly at idle. It also upgrades systems where coil whine or inconsistent voltage rails cause instability. Builders needing more than 550 W or additional PCIe connectors should look elsewhere.
