Question Can I use an 8 pin connecter and 6+2 (using the split 2 pins on a different psu slot) for my rtx 3080

[weebaros2008]

So, I recently bought an rtx 3080. But I've run into a problem. my psu (being an old thermaltake 750W) only has one 8 pin "slot"and it has 4 6-pins. I have 2 cables for the gpu. An 8 pin to 8 pin and a 6+2 to 8 pin. Would it be better if i just left the 2pins out and plugged the 8 pin to it's slot and did the same with only the 6 pin (without the other 2 pins), would it better to connect the remaing to pin to another psu slot (like one of these 6 pins i have, and have it occupy 2 of the 6 pins in that slot) or do i need to get a new psu?

More speciffically my psu is:

What exact psu? Old psu and a 3080 sounds bad.

It's a thermaltake toughpower W0117 semi modular 750W up to 85% effiecient(an older model). I've been using it with my rtx 2060 and there have been no problems for the past 2 years.

I wouldn't power a 3080 with a PSU released in 2006. I would not connect it to an outlet.

As noted in your other thread, you NEED a new PSU.
Period.
Do not power up this system with that PSU.

Question - old psu and rtx 3080

So, i recently bought an rtx 3080 and I am wondering if my old psu (Thermaltake Toughpower W0117 85% efficiency) could run my gpu with out any problems or if maybe i need to buy a new one. I've been using it for two years with my rtx 2060 and it's been performing great and without any problems...
