ROG Strix GeForce RTX® 4090 OC Edition

The new ASUS Republic of Gamers (ROG) Strix GeForce RTX 4090 OC represents the very best air-cooled custom-design implementation of the new NVIDIA flagship that ASUS has to offer, and we're reviewing it today. The ROG Strix brand was originally designed as a notch below bleeding-edge brands like the ROG Matrix and ROG Ares; but over the years has become one of the top custom-design graphics card brands to look out for, spanning all market segments. With the RTX 40-series, ASUS is dialing things up a bit, with an extremely premium product design that looks as much a work of art as technology; and has given it the company's highest factory-overclock for air-cooled graphics cards. In this review, we have the factory-overclocked "O24G" SKU of the RTX 4090 ROG Strix.

FanConnect II

Hook up

Two PWM FanConnect headers provide additional DIY flexibility. Chassis fans can be directly attached to the card and tuned with a curve that is based on CPU and GPU temperatures, delivering extra intake or exhaust for demanding 3D tasks.

Reinforcements

Additional Perks

A GPU bracket provides extra stability to the critical connection between die and heat spreader. The rear I/O bracket is made from stainless steel to prevent corrosion in humid climates and provide a more resilient mount. A conveniently placed Dual Bios switch allows quick selection between “performance” and “quiet” speed profiles for the Axial-tech fans.

Power Sensing

Quick Diagnosis

Know if your PSU is worthy. ROG Strix GeForce RTX 4090 graphics cards feature a high-speed circuit that constantly monitors input power from the PSU and utilizes conveniently placed LEDs to indicate voltage regulation issues and cable connection problems.
