Early GeForce RTX 5090 prototype leaked with quad 16-pin power connector setup

A new image has leaked online, showing what appears to be a wild early prototype of NVIDIA’s GeForce RTX 5090. This leaked version looks nothing like the final product but gives us a rare peek into how NVIDIA builds and tests its flagship cards.

Spotted by X user YuuKi_AnS (via Winfuture.de), the RTX 5090 leaked prototype shows an unusually complex PCB layout and four separate 16-pin power connectors. That setup alone suggests NVIDIA was stress-testing for extreme power draw.

If all ports were used, this thing could theoretically consume up to 2,400 watts. For context, the retail RTX 5090 tops out at 575 watts, already pushing the limits of most PC cooling setups.

The image also shows diagnostic pins and USB ports, which are typical for engineering samples. Interestingly, the board was physically cut in half, likely for closer inspection or component isolation. Some speculate this could even hint at an early build for a future RTX 5090 Ti or workstation-level RTX Pro 6000 Blackwell model.

The prototype’s multi-layer PCB design suggests NVIDIA was experimenting with better thermal and power delivery performance. That lines up with what we know about the Blackwell architecture—smaller manufacturing nodes and improved efficiency across the board.

And this isn’t the first test board we’ve seen. An earlier leak from January showed a different 5090 prototype with two connectors and a rumored 800-watt TDP. That version reportedly packed more CUDA cores than what will ship in the final product.
