A recent experiment by YouTuber JayzTwoCents tested the GIGABYTE RTX 5090 AORUS Master graphics card by applying a special 1000W BIOS from the ASUS ROG Astral RTX 5090. This test, shared on July 27, 2025, aimed to see how much extra performance the card could gain and what challenges might come up.
The ASUS BIOS allowed the GIGABYTE RTX 5090 to use up to 1000W of power, compared to its usual 600W limit. With some tweaks to the card’s settings, it achieved a 10.3% performance increase in the 3DMark Port Royal test, scoring 43,315 points, enough to rank in the global top 100. However, just adding more power didn’t automatically improve performance—manual adjustments to the card’s speed were needed to see these gains.
The test wasn’t perfect. One of the card’s three fans stopped working because the ASUS BIOS only supports two fan controllers, while the GIGABYTE card uses three. JayzTwoCents replaced the stopped fan with a custom one for better airflow.
The card also struggled with stress tests at 1600W, so it was set back to 1000W for stability. The GIGABYTE card uses less powerful components (50A power stages) compared to the ASUS card (80A), which limited how much extra power it could handle.
Using 900W or more increased power consumption by over 33% compared to the standard setup. This high power draw raises concerns about overheating, especially since the card’s power connector can get very hot (up to 65°C). A strong power supply (at least 950W) and good cooling are needed to avoid issues like melting connectors.
Changing the BIOS is risky and not recommended unless you’re an expert. It can void the card’s warranty, and without a backup BIOS, a mistake could break the card. The GIGABYTE RTX 5090 has a dual BIOS feature, which offers a fallback if something goes wrong.
This test shows that the GIGABYTE RTX 5090 can get a noticeable performance boost with the ASUS 1000W BIOS, but it comes with trade-offs like a disabled fan, high power use, and potential hardware limits.
For most gamers, the extra power might not be worth the risks unless you’re aiming for record-breaking performance with custom cooling. Check out JayzTwoCents’ video below.
