High-capacity ATX power supply

The KHACHIMO 3000W unit delivers 80 PLUS Gold certified efficiency for workstations and servers that demand sustained high-output power. Its resonant LLC topology with DC-to-DC conversion supplies clean, consistent voltage rails across heavy loads.

Thermals and acoustics

A zero-RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent operation. Gold-level efficiency reduces waste heat, lowering internal temperatures and overall power draw during typical use.

Build integration

Modern Standby compatibility enables extremely fast wake-from-sleep transitions and efficient low-power states. The ATX form factor fits standard chassis layouts while the high wattage headroom supports dense component configurations without requiring additional power sources.

Questions about this item

How do I install this ATX power supply in a standard case and which step is often missed?

Mount the unit with four screws, connect the 24-pin ATX and CPU power cables, then enable Modern Standby in the BIOS so the fast wake-from-sleep feature actually works.

What maintenance will this 3000 W Gold unit need over its life?

The Zero RPM fan stays off at low loads, so dust builds up slowly; clean the intake grill once a year and listen for bearing noise — if the fan becomes audible under load, plan a fan swap.

Which limit appears first when the supply runs at high output for long periods?

The 80 PLUS Gold certification guarantees efficiency up to full load, so the 3000 W ceiling is the first hard stop; sustained draws above that trigger protection and shut the unit down.
