ASUS ROG-STRIX-850G-AURA-GAMING 850W power supply

What this power supply delivers

The ASUS ROG Strix 850G Aura Gaming is a fully modular ATX 3.0 power supply rated at 850 W with 80 Plus Gold efficiency and Cybenetics A++ noise certification. It includes a 16-pin PCIe 5.0 connector capable of 600 W, two CPU 4+4-pin cables, three 8-pin PCIe cables, five SATA and four peripheral connectors. An aluminium case and large ROG heatsinks work with an Axial-tech fan using dual ball bearings to keep temperatures and acoustic output low, while 0dB mode stops the fan under light loads. Aura Sync lighting adds addressable RGB control.

Who this suits and who should look elsewhere

Builders assembling a high-end ATX 3.0 system with a PCIe 5.0 graphics card will find the native 16-pin cable and 850 W headroom a direct fit. The fully modular cable set and compact 180 mm depth simplify cable routing in mid-tower cases. Users planning multi-GPU configurations or workstations that demand more than 850 W should consider higher-capacity units. Systems that rely on legacy 6-pin PCIe power or need more than five SATA devices will require additional adapters or a different supply.

What to verify in your build before ordering

Confirm your case accepts a power supply up to 180 mm long, 150 mm wide and 86 mm tall. Check that the motherboard uses a standard 24-pin ATX connector and one or two 8-pin CPU power headers. Ensure the graphics card requires either the 16-pin PCIe 5.0 connector or up to three 8-pin PCIe connectors. Verify the mains input range of 100-240 V matches your local supply. No other interface or form-factor checks are needed for this unit.
