Hi, so I got this exact same PC from amazon for very cheap as the guy in the video and wanted to do an upgrade to it by adding a GPU which obviously led me to the mandatory quest for finding PSU adapters for the proprietary MoBo which wasn't hard although now that I just ordered the 24 to 6 pin adapter I noticed that the original Dell PSU comes with 2 connectors, as the MoBo has a 6 pin header on the bottom and a 4 pin on the top, so I was wondering how the guy in the video managed to make it work, is the 4 pin not needed or is there another adapter for it that he didn't show?
I left a comment on his video but realistically he's not gonna reply so I came here looking for help, also, I want to throw a 6650 XT or a 3060 in there despite the massive bottleneck the i5 6500 will make since I plan on building a decent PC with the same GPU and PSU later on but for the time being I'd like to squeeze as much performance out of the 6500 as possible. Thanks in advance.

As far as I'm aware, the 4-pin CPU header is the same as on normal ATX motherboards. I don't think they did anything to that so the 4-pin power from an ATX PSU will work there as well. It is needed and I would expect it to not boot without it as that's where the CPU gets it's power.
