ASUS ROG Strix 850W Gold ATX3.0 (850W/80+ Gold/ATX 3.0/Popular High-End Gaming Tier) Review

ASUS ROG Strix 850W Gold ATX3.0 850W 80 Plus Gold fully modular power supply, ATX 3.0 certified, ATX form factor, native 12V-2x6/12VHPWR connector, 10-year warranty, Seasonic platform.

The ASUS ROG Strix 850W Gold ATX3.0 is the mainstream ROG Strix PSU, giving Republic of Gamers case-matching aesthetics to a mid-range 850W Gold build without Thor-level pricing. Rated 850W at 80 PLUS Gold (Cybenetics Gold efficiency / A noise), it's built on a Seasonic platform with a 135mm fluid dynamic bearing fan running a zero-RPM semi-passive mode at idle. Fully Modular cabling and a 150mm chassis depth make it a realistic fit for a popular RTX 4070 Ti / RTX 5070-class gaming build, and it's backed by a 10-year warranty.

Efficiency, Noise, and Build Quality

The ROG Strix 850W Gold ATX3.0 carries an 80 PLUS Gold certification and a Cybenetics Gold efficiency / A noise rating, translating to consistently high real-world efficiency at typical 50% load and low fan noise thanks to its 135mm fluid dynamic bearing, axial-tech design. It uses a Seasonic platform with Japanese-made capacitors throughout for long-term reliability under sustained load.

Connectors and Cabling

Connector layout is 1x 24-pin ATX, 2x EPS 4+4, 1x 12V-2x6 (600W), 4x PCIe 6+2-pin, 8x SATA, 3x Molex. With 1 native 12V-2x6 connector(s) rated to deliver up to 600W to a single GPU, there's no need for a 4x8-pin-to-12VHPWR adapter on current-generation flagship cards. Cabling is fully modular, using standard flat or ribbon cables, with a single +12V rail design that simplifies load balancing across connectors.

Comparison to Alternatives

Against the Cooler Master V Platinum 3000 (Cooler Master's 3000W Platinum workstation monster), the ASUS ROG Strix 850W Gold ATX3.0 matches its wattage class but differs on connector generation and OEM platform, making the choice mostly about brand ecosystem, warranty length (10 years here), and whether native 12V-2x6 connectors matter for your GPU. Compared with the Seasonic Focus GX-750 (Seasonic's long-trusted 750W Gold workhorse), the ROG Strix 850W Gold ATX3.0 sits in the popular high-end gaming bracket at 850W, so the decision usually comes down to matching wattage headroom to your actual GPU/CPU combo rather than one being categorically better.

Expert rating8.3 / 10

A solid 850W Gold-rated ATX unit for a popular RTX 4070 Ti / RTX 5070-class gaming build, held back only by the usual mid-tier compromises on cabling and OEM sourcing.

Best for

Builders targeting a popular RTX 4070 Ti / RTX 5070-class gaming build
Anyone who wants fully modular cabling with native 12V-2x6 support
Systems where a 10-year warranty and Gold-tier efficiency matter

Not for

Builds needing more than 850W of continuous headroom
Buyers who need the smallest possible SFX/SFX-L footprint
Cost-sensitive builds better served by a lower-tier 80+ Bronze unit
