RTX 5090 Owners Beware: 3x 8-Pin Power Can Limit Performance Optimal Power Configuration

So, you've picked up a shiny new NVIDIA GeForce RTX 5090. Congratulations. You're at the bleeding edge of gaming and graphics power. But before you start maxing every setting known to man, there's a power-related detail you absolutely need to know. It seems that how you power this beast can directly impact its performance. And not in a subtle way. The 8-Pin Power Cable Conundrum It's a pretty simple thing: power cables. But, as it seems from recent findings, skimping on them with the RTX 5090 may leave some serious performance on the table. Tech pros at ComputerBase put the RTX 5090 through its paces, testing it with both 3x 8-pin and the recommended 4x 8-pin power connectors. The results? A pretty clear performance hit when running with fewer cables. "Supplying 100W less power than the optimal number results in a performance decrease of around 5% in rasterized tests." - ComputerBase Test Results Yes, you read that right. Just by using one less 8-pin power cable,…
