Black ATX power supply unit with fan grille and modular cable sockets

KHACHIMO

KHACHIMO PWS-703P-1R 750W power supply

SKU CH-3PMC-3686Y

ATX 750 W unit with 80 PLUS Gold efficiency, Modern Standby support, Zero RPM fan mode and resonant LLC plus DC-to-DC topology for clean, quiet power delivery

  • Product typeATX
  • Modern Standby gives extremely fast wake-from-sleep and better low-load efficiency
  • 80 PLUS Gold certification delivers high efficiency for lower power consumption, less noise, cooler temperatures
  • Zero RPM fan mode stops the cooling fan at low and medium loads for near-silent operation
  • Resonant LLC topology with DC-to-DC conversion provides clean consistent power and reduces coil whine
  • DC-to-DC conversion enables more energy efficient sleep states

750W ATX power supply for modern PCs

The KHACHIMO PWS-703P-1R is a new 750W ATX unit built for desktop systems that demand efficient, reliable power delivery. It suits builders who want a single-rail design with Gold-class efficiency and Modern Standby support for instant wake times.

Gold efficiency with semi-passive cooling

80 PLUS Gold certification means high efficiency at typical loads, reducing waste heat and keeping internal temperatures lower. Zero RPM fan mode stops the fan completely at low and medium loads for near-silent operation, while the resonant LLC topology with DC-to-DC conversion minimises coil whine and supports deeper sleep states.

Replaces older Bronze or non-Modern Standby units

This supply upgrades from older ATX units that lack Modern Standby compatibility or only meet Bronze efficiency, especially where sleep-state responsiveness and low-load noise matter. The jump is worth it when building or refreshing a system that spends long periods idle or in sleep and needs clean, quiet power without a higher-wattage overhead.

Questions about this item

How do I install the KHACHIMO PWS-703P-1R 750W ATX power supply and which step is often missed?

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

What maintenance or replacement will this 750W Gold unit need later?

Clean dust from the fan intake periodically; the Zero RPM mode keeps the fan off at low loads, reducing bearing wear, but the fan itself is the only moving part that may eventually require replacement.

What limit appears first under sustained load on this 80 PLUS Gold supply?

The 750 W continuous power rating is the first ceiling; the Resonant LLC topology with DC-to-DC conversion maintains tight voltage regulation up to that point, and the Gold efficiency rating keeps heat and noise lower as you approach it.
