[SOLVED] Can I use 8 pin when I use 6 pin connector for my PC?

[Pods]

I have a radeon 6850, I was hoping to buy a MSI GeForce GTX 1660 VENTUS which is and 8 pin GPU, so I wanted to ask if I can use 8 pin when I currently use 6 pin for my GPU and how do I. Some support would be nice.
Have a good day!

Well... you can (there are 6 to 8 pin adapters) but it's not recommended and that's not the only issue...( Safe bet is 2x6 pin to 8 Pin).
What PSU do you have?

I have a really old PC, thus the power supply is one that you may not find anymore on the market

I'm not writing because i want to buy it...
I'm writing because you need to know for the 1660 Ventus you need 450W Reputable brand PSU....

I think my power supply had like 800 something or was it 700 something W, so I reckon it can handle a 1660.

You need to tell us the exact power supply. And just because something claims a certain wattage doesn't mean it's actually that certain wattage or even safe - junk PSU manufacturers are known for just making up things.

The PSU is
Thermaltake is the brand
Litepower 700
mODEL: LP-700AL2NH

Well, it's not the worst PSU ever. But using adapters, a common source of melting and the occasional fire, with an ancient PSU of mediocre quality at best, is a situation I'd definitely avoid like the plague.

So should I just buy a RX 580 or what should I do

Anything that requires an eight-pin connector is inappropriate with this PSU.

If you're unwilling to replace an ancient, fairly low-quality PSU, your best GPU option is a 1650 that doesn't require a supplementary connector, which is still a massive upgrade on a 6850.

Adapters are almost never recommended because of the risks. The rare exception is a very high-quality older PSU and a 2x6 to 8 pin adapter. This isn't the situation here.
