YouTuber Pushes RTX 5090 Beyond 800W Using Dual Power Connectors
This one YouTuber really knows the extreme GPU power consumption. The host of the channel, Yugimuru, has now modified a GeForce RTX 5090 to push it to consume more than 800 watts, just as talks continue about the 12V-2x6 power connector.
The Ingenious Method of the Modification
Pushing any GPU to such limits mostly needs a particular model, such as the GALAX HOF or one from the series of ASUS ROG Matrix, all having two power connectors. However, Yugimuru found a cunning workaround using a GIGABYTE RTX 5090 AORUS Stealth.
This peculiar card has a pair of power inputs a regular connector, and the second connection is from GIGABYTE for its Stealth hidden-cable setup. By connecting power cables to both ports at the same time, the modder confirmed their operation in parallel on the same 12-volt line and effectively doubles the power delivery potential.
Custom Cooling and Overclocking Results
The stock cooler had to be removed first for physical access to the second connector. It now has the custom water cooling loop attached, which kept it at a promising 67 degrees Celsius under load.
The increased supply power has allowed for much more significant overclocking producing excellent results:
- GPU Frequency: Core was pushed to 3.2GHz up by 545MHz over default speed;
- Power Consumption: While the card's BIOS showed 485W, real measurement shows approximately 808W consumed;
- Total system draw: This was further reinforced with a total system draw of 975W from the wall as well.
This experiment can be watched in full detail under the YouTube channel of Yugimuru since it has plenty of power overhead for extreme overclocking on the RTX 5090 even without power limits.
