Hello! Your build looks great with the Radeon 7900 xtx Taichi and those connectors. You're wondering if you can use a single extension cable for all three types—8-pin, 8-pin x1, and 6+2-pin x1. Yes, there are good triple 8-pin extension cables available that would simplify things and improve the appearance. Let me know if you need recommendations!

Making those changes won't give you enough power in the game and could overload the cable. For your safety... stick to one cable port. An 8-pin PCIe cable can handle around 150 watts max. If you rely on just one cable and your GPU uses more power, it might damage the cable or stop working entirely. Avoid using extensions or pigtails on high-end GPUs—they have power limits around 350 watts. To run that overclocked setup, you'd typically need at least three cables. Some users report seeing draws as high as 650 watts, which usually requires four cables for stability.

I use a 250W GPU with one 8+6+2 cable without issues, but in most cases I think two separate cables are better than one.

they always underspec limits.. but i belive that would work just fine.. the pcie socket in the psu can draw 280w.. and deliver 150w on the 8pin at the gpu. the answers in this thread has a good list on what psu's draws.. and what it delivers at the gpu sockets. https://superuser.com/questions/1577923/...tor-output what he wants to do is be able to draw 450 watts from a psu socket not delivering more than 280w. .. ok the card has a max of 350w.. but that's the theoretical max draw. 150w pr daisychained 8pin connector. it will probably melt the cable as it is out of spec.
