Question Buy a new 8-pin PCIe cable or convert my two existing 6 Pin to a single 8 Pin?

I mentioned that one of the reasons I am going with an RTX 2060 Super is that it's basically the best GPU I can get for $200 or less that uses a single 8-pin.

I think the confusion might have come from that I mentioned that my current GPU is 6-pin, that my system has a 2x6pin cable, and that I would not be able to split this safely into 6+8 or 8+8 pin and was asking if going 2x6 to 1x8 was safer than just finding a 1x8 to 1x8 cable to plug directly into my PSU. Since I mentioned just about every configuration that I can and cannot do I can see where it could be easy to forget I mentioned that I was going for a single 8-pin GPU (Since I highly doubt any RTX 2060 Supers were 1x6 or 2x6).

Even those single-fan OEM style cards are 8 pin..... and honestly, I am tempted to go for those over the larger retail 2 or 3 fan models since this is a smaller enterprise case since they would likely be easier to cool and power in this thing (and the power plug on most of them is on the side instead of top, just like my current GPU's is, I have no idea how much clearance I would have to route a cable from the top.

Basically, the cable I have right now that came with the system look like this:

The 8-pin end (Which I assume is a proprietary pinout) plugs into the PSU, it splits into two 6-pin plugs. One is plugged into my Quadro K4000 GPU, and since the GPU only has a single 6-pin port the other end of the cable is just plugged into nothing.
Wow, I've never seen a connector like that before and I've been building PCs for over 30 years. Maybe that's the problem though. Since I was never interested in those "brand-in-a-box" desktops that get all the weird things like that, I never saw them.

It makes me wonder if there's a connector that does the opposite and takes two 6-pins to merge them into an 8-pin. One thing that I have learnt over the decades is that almost every type of connector has an counterpart that does the exact opposite thing. I'll look on newegg...

Sure enough, I think that I've found what you need here:
OIAGLH Dual 6 Pin Female to 8 Pin Male GPU Power Adapter Cable (2 Pack)

Now I know this is a 2-pack and you don't need a 2-pack, but at least it verifies that what you need exists. Maybe they're available individually through a source near you.

Yes, that's the connector I was talking about, if it would be better to find an 8 to 8 that's made for my PSU or just to convert those standard dual 6pins to a single 8.
