@KB, Now tell me, what you wanting to achieve inhere, I’m talking about an 2*6 to 8 pin PEG, not going from a Molex to an 8pins PEG. You are talking about something complete differently and I do not think the Molex is being designed for high Amps, to me it appears the PEG is more suited.

Now for the TS, sorry that it end complete OT, but be aware, if installing your GTX1050ti it could give problems in Dell systems specific, even if you have deleted all the drivers by using a Vcard driver cleanup software or reinstall your HD. Wayback in 2009 I did do modifications on my Dell 521, like another Vcard etc. all to play OFF3 at a decent level and I did encounter that freaking Dell problem. I know it is now 10y later but If facing that problem, you never know, read my remarks as the solution can be found in this post.

Now I will not bother you with my talk and stop from now.
Good luck.
