RTX 5090 Graphics Card Works Well with Less Power.
New tests show NVIDIA's RTX 5090 card can run on lower power in small computers. The card needs three 8-pin cables instead of its special power plug. This setup cuts power use from 575 watts to 450 watts.
German tech site ComputeBase found that games run just 5% slower at the lower power level. The card needs all three power cables to start up; two cables will not work.
Each 8-pin cable gives the card 150 watts of power. Three cables add up to 450 watts - less than the full 575 watts but enough for good performance. The card can also draw 75 watts through its slot in the computer.
Users who reduced power to 400 watts saw a 10% drop in speed. Most buyers prefer the 450-watt setting, which keeps the card running strong without special power parts.
These findings help people build smaller computers with high-end parts. The RTX 5090 proves it can adapt to different power needs without losing much speed.
