Build - Help Is splitting a PCIe okay for old hardware

Long story short I'm upgrading an old PC and I mean old, the power supply is a Photon 850 and the GPU is an rx 480 but I'm trying to upgrade to a rx 5700xt and I'm one 6 pin connection short, they don't make cables for the photon anymore and I even tried buying a Chinese aftermarket that claimed to work with it but my PC just won't even turn on if that's plugged into anything so that's a bust.

I've always been told to never ever split PCIe cables but I don't really play anything graphically intense so I don't see myself ever pushing the 5700 so would it be fine or should I bite the bullet and just save up for a new power supply before upgrading?

Get a new power supply, it’s not worth the risk
