750W ATX Power Supply for Modern Standby Systems

The KHACHIMO PS-2751-5LD delivers 750W of continuous power in a standard ATX form factor. It is built for desktop builders who need reliable energy delivery and compatibility with Modern Standby sleep states for near-instant wake times.

80 PLUS Gold Efficiency with Zero RPM Fan Mode

Certified 80 PLUS Gold efficiency reduces power waste, lowering heat output and electricity draw during typical workloads. A Zero RPM mode stops the fan completely at low and medium loads, while resonant LLC topology with DC-to-DC conversion minimises coil whine for quieter overall operation.

Resonant LLC Topology Enables Efficient Sleep States

The internal resonant LLC design with DC-to-DC conversion provides clean, consistent voltage regulation across all rails. This architecture directly supports the deeper, more energy-efficient sleep states required by Modern Standby, improving system responsiveness without extra configuration.

Questions about this item

How do I install the PS-2751-5LD in a standard ATX case and what step is often missed?

Mount the unit with four screws, connect the 24-pin ATX, 8-pin EPS and PCIe cables to the motherboard and GPU, then enable Modern Standby in the UEFI so the fast wake-from-sleep feature actually works.

What maintenance will the PS-2751-5LD need over its life?

Clean dust from the intake grill once a year; the Zero RPM fan mode means the fan spins less often, so bearing wear is minimal and no scheduled replacement is required.

Which limit appears first when the PS-2751-5LD runs at high load for long periods?

The 80 PLUS Gold efficiency target drops above 750 W output, so sustained loads beyond that rating trigger protection shutdown before thermal limits are reached.
