I have a Powercolor Reaper GPU that requires two 8-pin connections. My Segotep Radiant case comes with a 750W 80 Bronze PSU, but it only has one cable that splits to two 8-pin connectors. The cable is labeled 18 AWG, rated for 300V and 80°C. I'm wondering if using a daisy chain like this is safe for my setup.

Honestly, using a single PCIE cable for your 9070 XT isn’t a great idea. Under full load, this GPU can draw over 350 watts, but a typical PCIE cable is only rated for about 300 watts maximum. This could lead to instability or even risk damaging your GPU or PSU if the cable is compromised. You should really consider getting a higher quality PSU that has at least 4 PCIE 8-pin connectors on separate cables to ensure everything runs safely and efficiently.
Yeah, it's all about safety. Better to invest in a reliable power supply than risk your expensive components!
