It doesn't have 6 pin connectors, so I was wondering if it was safe.
Thanks to GPU Boost 3.0, your 1050 is already probably boosting to over it's rated boost, as it'll overclock as high as it can go within the stock boundaries (higher than rated.)
If you want to play it safe, you can always just increase the power limit in something like MSI Afterburner, and let the card auto-overclock itself, while still remaining within safe operating limits.
Watch this video from Jayztwocents for help. Hope this is useful man!
If it is an EVGA card with an ACX 3.0 Cooler on it they are having Heat issues anyway, so I would definitely keep it at stock..
It's an ACX 2.0 cooler.
Yes as long as you have thermal head room.
