GIGABYTE RTX 5090 Tested with 1000W Custom ASUS BIOS
In a new test, YouTuber JayzTwoCents put a 1000W custom BIOS from an ASUS ROG Astral RTX 5090 into a GIGABYTE RTX 5090 AORUS Master. The aim was to see how well the GIGABYTE card could do when it had a lot more power than its usual 600W.
Troubles with the Custom BIOS
The BIOS change worked, but it made some big issues:
- Hardware issues: The custom setup turned off the first fan on the GIGABYTE GPU. So, JayzTwoCents had to put in a new fan to keep the air moving.
- Not stable at Max Power: The card could not handle stress tests at the BIOS's full 1600W max (done via MSI Afterburner). He had to bring it back down to 1000W.
More Power vs. Better Results
Just raising the power limit did not give better results by itself. Even with the new BIOS, the card used up to 800W but only gave a small boost in use.
But, with good air cooling and manual speed changes, the test got a big result:
- A 10.3% higher score in the 3DMark Port Royal test.
This result put it in the top 100 in the world.
This better result came with a big jump in power use. The card used 900W to get the 10% boost, 33% more than its normal 600W.
Why it Hit Limits
The GIGABYTE RTX 5090 AORUS Master had a hard time with the very high power due to its build. It has 50A power stages, but the ASUS ROG Astral RTX 5090 uses stronger 80A power stages.
This is why the ASUS card can handle the custom BIOS and high power better, while the GIGABYTE card reaches its build limit sooner even with the unlocked software.
