It would be even worse than using a dual 6 pin to 8 pin adapter. At least the two 6 pins are built for GPU loads and together cover the power requirements you might need. Molex connectors can handle up to 54W, so combined they could reach around 108W, though it might be less.
That's true but there's a real 150W connector on the other side. Just how much juice are you expecting an RTX 2060 card to draw? Even if they used two, that would mean the card could draw over 275W. Since they're using one, the card can draw over 325W. I've never seen my RX 6800 XT draw more than 325W even when mining with it. You didn't stop and consider all of the numbers did you?
It's worth a try and if it's not enough, it won't hurt anything, thePC will just do a hard reset crash. I wouldn't use two of those connectors (even though you could), but I wouldn't be afraid to use one. Those connectors have been on the market for well over a decade. If they were even half as bad as you seem to think that they are, they would've been discontinued years ago. Since they haven't, they work. They're made specifically for situations like the OP's where the PSU doesn't have the connector that they need.
Do you honestly think that a (relatively) dinky card like an RTX 2060 draws as much power as an RX 6800 XT? The power draw of an RTX 2060 is only 190W. I really think that you're overestimating what that card needs. Being willing to run a card on some proprietary PSU that some company put in a brand-in-a-box PC is a lot more of a risk than using a single molex to PCI-Express connector and is a lot less of a risk than screwing around with wires.
If you had taken the time to actually go and see what the RTX 2060's power needs are, you might have saved yourself from making that post. I'm actually shocked that it has two 8-pin ports on it because one 8-pin and the PCI slot alone deliver over 200W. There is no risk to this card from using that connector.
He mentioned directly in the original post that the GPU has a 1 8-pin power connection....
Additionally, the slot supplies 75 Watts of power. If your 190W RTX 2060 is accurate (I haven’t checked), then the card must draw 115 Watts from the PSU connector. In that scenario, the 108W maximum of the Molex connectors is clearly insufficient for the power required.
I noticed that point too. You're absolutely correct and I'm right here. I assumed there were two options, which seemed unusual. That's why I believed you were expecting a 275W draw. Actually, I haven't seen a card with just one 8-pin connector in a long time. In fact, I never owned one that only needed one. I didn't realize they existed.
For a single 8-pin connector, I fully agree it wouldn't be enough. The issue is whether the power required from the connected wires can be supplied by a brand-in-a-box PSU. For their sake, I really hope so because I know those PSUs often don't work well.
I noted that choosing an RTX 2060 Super is mainly due to its affordability under $200 and its use of a single 8-pin connector. I believe the mix-up may stem from my current setup, which uses a 6-pin GPU, a 2x6 pin cable, and a system with a 2x6 pin connection. I wasn’t sure if splitting it safely into 6+8 or 8+8 pins was necessary. I was wondering if switching to a single 8-pin card would be safer rather than trying to connect directly with an 8-pin cable to the PSU. Since almost every configuration I can and cannot use, it’s clear I might have overlooked my goal of getting a single 8-pin GPU—especially since no RTX 2060 Super is likely to be 1x6 or 2x6. Even the standard OEM-style cards are 8 pins. I’m leaning toward opting for those compact, single-fan models instead of the larger retail options, as they should be easier to cool and fit in my smaller case. The power supply port is usually on the side, similar to my current GPU, making it hard to route a cable from the top without much space.
