700W ATX power supply for Modern Standby systems

This ATX power supply delivers 700 watts of continuous power and is built for PCs that use Modern Standby sleep states. It suits builders who want high efficiency and quiet operation in a standard desktop form factor. The unit carries 80 PLUS Gold certification for reduced waste heat and lower electricity draw.

Gold efficiency with Zero RPM fan mode

At low and medium loads the cooling fan stops completely, giving near-silent operation while the 80 PLUS Gold rating keeps temperatures down. Resonant LLC topology with DC-to-DC conversion supplies clean power and cuts coil whine, so the system stays cool and quiet during everyday workloads. Efficiency remains high even at light loads thanks to Modern Standby optimisation.

Modern Standby support for instant wake

Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency than traditional supplies. The resonant LLC and DC-to-DC design also allows deeper, more energy-efficient sleep states without voltage instability. Builders who need legacy sleep states or who require modular cabling will not find those features here.

Questions about this item

How do I install this 700W ATX power supply in a standard case and which step is often missed?

Mount the unit with four screws, connect the 24-pin ATX, 8-pin CPU and PCIe cables, then enable Modern Standby in the motherboard BIOS so the fast wake and low-load efficiency features actually work.

What maintenance will this YM-2701QBR unit need over its lifetime?

Clean dust from the intake grill every six to twelve months; the Zero RPM fan mode means the fan spins less often, but when it does run dust still accumulates and can restrict airflow.

Which limit appears first when this 80 PLUS Gold supply runs at sustained high load?

The 700W continuous output rating is the first hard ceiling; the resonant LLC topology with DC-to-DC conversion keeps voltage regulation tight up to that point, so thermal protection only triggers if the load exceeds the rated wattage.
