I sensed it might be similar. Fortunately, the WiFi works at least now without the antennas. Could the absence of the 8-pin 12V connector on the PSU be the issue? I was thinking about upgrading it anyway, so ordering a new one now could save $15 and avoid buying a network card.
There can be problems. Make sure to install the chipset drivers first. It mentions Intel chipset drivers, but you should click on "Show more" on the site—select every category and download the latest ones. Avoid installing Armory Crate; instead, go with AI Suite 3, which is preferable. You'll still need the chipset and storage drivers, so visit the NVIDIA website for GPU driver support.
I checked your message again to clarify what cable you're referring to. Usually, the 8-pin and 4-pin EPS CPU power connectors on the motherboard match what you described—8-pin for priority and 4-pin for extra power needed during overclocking. This shouldn’t impact things since the chipset for Ethernet will be powered through the 24-pin motherboard cable. I’d probably reach out to the seller on eBay to let them know some connections aren’t working and ask for a partial refund or return. If it was a private sale on sites like Facebook Marketplace or Craigslist, your chances are much lower.
