pavilion 590-p0056

Good morning, I’m wanting to upgrade from a GTX 1050 to a GTX 1060 GPU. I have a prebuilt HP Pavilion 590-p0056. It has a 310w Proprietary PSU without a 6 pin connector. Do parts exist to make this work? HP has a 400w power supply that fits but I can’t find if there’s a 6 pin on it. Thanks in...
