  • Product typeATX
  • Faster wake-from-sleep with Modern Standby support

700W ATX Power Supply for Modern Standby Systems

This KHACHIMO 700W ATX unit targets builders who need a Gold-efficiency supply that supports Modern Standby sleep states. It suits workstations and high-performance desktops requiring clean power delivery and fast wake-from-sleep response. The resonant LLC topology with DC-to-DC conversion ensures stable voltage regulation across varying loads.

80 PLUS Gold Efficiency with Zero RPM Fan Mode

At low and medium loads the cooling fan stops completely, delivering near-silent operation during typical desktop tasks. The 80 PLUS Gold certification confirms high efficiency that reduces power consumption, waste heat and overall system noise. Resonant LLC topology further suppresses coil whine for quieter performance under load.

Replaces Lower-Efficiency

This supply upgrades older ATX units that lack Modern Standby compatibility or Gold-rated efficiency. The jump is worthwhile when building or refreshing a system that uses deep sleep states and demands lower idle power draw. It is not suited for builds requiring higher wattage than 700W or non-ATX form factors.

Questions about this item

How do I install the 700W ATX power supply and what step do people often get wrong?

Mount the unit in the case with four screws, connect the 24-pin ATX, 4+4-pin CPU, and required PCIe cables, then ensure the main power switch on the rear is set to "I" before pressing the case power button — the step most often missed is leaving the rear switch off.

What maintenance will this 80 PLUS Gold unit need later?

Clean dust from the intake and exhaust vents periodically; the Zero RPM fan mode means the fan stops at low loads, so dust buildup can reduce airflow when the fan eventually spins up.

What limit appears first during sustained heavy loads on this 700W supply?

The 700W maximum output is the first limit; if total system draw reaches that level the protection circuits will shut the unit down to prevent damage.
