I recently got an RX 9070 XT graphics card, which comes with three PCIe power connectors. My current power supply only has two PCIe connectors available on it (which split into two from a single cable), and while I'm planning to upgrade my power supply soon, I'm curious if I can still hook up just two of the connectors to the GPU for now. Will that work, or will I run into issues?

Just FYI, a 750W PSU usually should have more than two PCIe connectors. Make sure you check the specs on your PSU; that doesn't sound right!
Yeah, it probably won't even start up. These connectors are there for a reason, and skipping one could mean your GPU isn't getting enough power.
You definitely need to connect all power connectors on the GPU. If you only use two, it's likely not going to work properly, and you may run into boot issues.
I tried running mine with only two connectors once and it didn't boot at all, so I wouldn't recommend it.
Mine is a DELTA-F 750-P with just those two connectors; maybe it’s time to consider a new power supply.
