770W ATX Power Supply for Modern Standby Systems

The KHACHIMO DPS-770AB delivers 770W of ATX power with 80 PLUS Gold certified efficiency. It is built for desktops that require fast wake-from-sleep response and low idle consumption. The unit uses resonant LLC topology with DC-to-DC conversion to supply clean, stable voltage rails.

Replacing Older Units Lacking Modern Sleep Support

This supply upgrades systems that cannot enter modern low-power sleep states or that suffer from coil whine under light loads. The jump is worthwhile when the current PSU prevents the platform from using energy-efficient idle modes or produces audible noise at low power draw. It also suits builds needing the 770W headroom for multi-GPU or workstation configurations.

Limits of ATX Form Factor and Gold Efficiency

The ATX form factor restricts physical dimensions, so the unit fits only standard ATX cases and cannot serve small form factor builds. Gold certification guarantees efficiency above 80% at typical loads but does not reach Platinum or Titanium levels at very light loads. The zero RPM fan mode operates only up to medium loads; sustained high output will engage active cooling.

Questions about this item

Will the 770W ATX unit fit a standard ATX case opening?

Yes, the power supply follows the ATX form factor so it mounts in any standard ATX case opening with the usual four screws.

What is the one step builders often miss when installing this PSU?

Connecting the 24-pin ATX and 8-pin CPU cables fully seated before routing them behind the motherboard tray.

Does the 80 PLUS Gold unit need any periodic maintenance?

Only occasional dust removal from the fan intake; the Zero RPM mode means the fan stops at low load, reducing bearing wear.
