Asus ROG Astral GeForce RTX 5080 OC Ed.: Brutalism in PC

With the new generation of GeForce GPUs, Asus is introducing the new ROG Astral series. Positioned at the top of Asus’s lineup, it inherits high-end features from previous ROG Strix models, including a dual BIOS, system fan control, a robust design, factory overclocking, and a large, top-notch cooler. It doesn’t just come with three but a total of four fans. However, this premium package comes at a significant price.

The fan noise fluctuates in certain areas of its range. Even under normal load, you may occasionally notice the tone of the fan speed changing.

I measured the operational characteristics during the Cyberpunk benchmark with RT Medium settings at a resolution of 3840 × 2160. With this setup, the graphics chip is almost fully loaded even with the high-performance BIOS. I did eight consecutive benchmark runs.

The graph always shows the last run, from which the average value for a warmed-up card is calculated.

The frame rate hovers at around 41.9 frames per second.

The card’s clock speed holds steady around 2893 MHz.

With this setup, the card’s power consumption is around 379 W according to the monitoring, which is below the power limit of 400 W in the Performance mode. This suggests that the chip is not fully maxed out.
The total power consumption of the PC, measured with the UT71E multimeter, is shown in dark color. The green line represents the power consumption of the card based on monitoring, and the blue line shows the processor’s power consumption according to monitoring (measured through HWiNFO).

Even with a high TDP, the temperatures remain relatively low, but this comes at the cost of high fan speeds.

In Performance mode, the fan speeds reach uncomfortably high values. At 2110 RPM, the noise level reaches 51.1 dBA, which is significantly louder than the Founders Edition.

Asus ROG Equalizer: Robust 12+4pin connectors that don’t burn?

Failures of the 12V‑2×6 power cable (formerly 12VHPWR) have become the scourge of recent GPU generations. Especially for Nvidia cards pushing this power standard, but also for a few Radeon models using these connectors. Various attempts to work around or mitigate the risks have popped up; this time, Asus is introducing the Equalizer special‑purpose cable for its power supplies, that aim to prevent connector melting in several ways.
