ᴠᴀɴǫᴜɪsʜ 7 - (ˡᵉᵛᵉˡ ¹) a "cheap

The first level of the Vanquish 7 is unfortunately not ready for VR, I made the mistake of ordering the device before I did any research out of sheer excitement to use virtual reality. The main problem here was the integrated graphics card (Radeon RX Vega 11) which only had a singular HDMI port and nothing else of note (the HTC Vive set requires a minimum 2 HDMI ports or 1 HDMI port and 1 DisplayPort) after figuring out that the Vanquish 7 was not suitable for the HTC Vive, I set out and purchased a GTX 1060 6GB graphics card (Minimum System Power Requirement (W) 400 W [directly from GeForce's website] and the 600W power supply within the Vanquish 7 should be slightly more than enough, and when the usual setup for the new GTX card was done (removing the old card's drivers, installing the new drivers for the 1060, and inserting the 1060 into an open PCI-E slot) the monitor only showed a normal "requires more power" screen, which meant that the card was detected successfully by the Vanquish, but still had insufficient power. After looking around for a 6pin-power outlet within the motherboard, I discovered that there wasn't one to be seen. I decided to then try to take the power directly from the power supply (and my assumption should be correct if even the first tier of the Vanquish has a power supply which claims to be able to support up to a 1080 [unless the problem stems directly from the fact that the Vanquish came with integrated graphics which would, in turn, affect how many cables the power supply had or the mystery of there being no pin-outlets within the motherboard])  however, the power supply is covered with a sheet of metal to prevent damage or loosening of the power supply, I attempted to dig around and find an 8-pin power cable to connect directly into the 1060, and believed that I saw a few spare cables inside of the metallic box concealing the power supply, but none of them had a label and were too far in to be able to expose the cables even with tools. I am pleading for a confirmation as to whether there are spare cables inside the power supply for a GTX 1060 6B and an explanation on how to expose the power supply, in case I have to swap it out for a different power supply with cables that the default power supply may not have.
I'd also highly appreciate some suggestions as to what components to purchase if anything goes south.

I apologize for making this whole thing sound like an angry rant or a boring spiel but I'd really love to start using VR soon!  -𝔯𝔢𝔪𝔦
