@ARandomPcUser , welcome to the forum.


The motherboard in your computer is HP proprietary.  It has a 4-pin power connector instead of a standard 24-pin ATX power connector.  Therefore, you will have to buy an upgraded PSU from HP.  Here is a Power Supply Cross-Reference Chart to show you what is available:


Your model series (690) shows a 310W, 400W and a 500W (L05757-800) that are compatible with the motherboard.  The 500W PSU has a PCIe 6+2 power connector.  However, I don't believe that this is enough power for the RTX 3070 video cards.  The specifications from nVidia show the minimum power requirement is 650W:
