Someone on toms hardware said : You don't need a PSU upgrade with the Zotac GTX1050Ti Mini. Just buy the card and stick it in. Save the money for extra RAM, or a CPU upgrade. An SSD if you don't already have one. The PSU will make absolutely no difference. I know the card maker says you need such and such a PSU. But that's for systems with more powerful CPUs and lots of expansion bays, and slots. That PSU can power anything that the MB has a connnector for. Only if you add a GPU that needs a separate power cable will you need a PSU.
