850 W Gold semi-modular ATX power supply

The EVGA 850 GQ delivers 850 W of continuous power through a single +12 V rail rated at 70.8 A. It uses a semi-modular cable layout so only the essential 24-pin motherboard connector is fixed; all peripheral cables can be added as needed. The unit carries 80 PLUS Gold certification with typical efficiency of 90% at 115 VAC and 92% at 220-240 VAC.

180 mm depth limits case compatibility

At 180 mm long the power supply fits most mid-tower and full-tower chassis but may not suit compact cases designed for shorter units. Active PFC accepts a universal input range of 100-240 V at 50/60 Hz so the same unit works worldwide without a voltage switch. Over-voltage protection is built in to guard connected components.

135 mm fluid-dynamic fan with ECO mode

A 135 mm fluid-dynamic bearing fan provides cooling and stays completely stationary until internal temperatures reach a defined threshold. EVGA ECO Intelligent Thermal Control keeps the supply silent at low to medium loads while 100% Japanese capacitors support long-term reliability. Eight 6+2-pin PCIe connectors and nine SATA power connectors cover multi-GPU and storage configurations.

Questions about this item

Which capacity should I pick for this EVGA 850 GQ series?

This model delivers 850 W maximum power on a single +12 V rail rated for 70.8 A, so select it when your build’s peak load fits within that ceiling.

What does the 80 PLUS Gold rating mean once the unit is installed?

It guarantees at least 90 % efficiency at 115 VAC and 92 % efficiency at 220–240 VAC under typical loads, reducing waste heat and lowering electricity draw.

How does the semi-modular design and fixed 24-pin connector affect cable routing?

The 24-pin main cable is fixed; the eight 6+2-pin PCIe and nine SATA cables are detachable, letting you connect only what the build needs.
