HP270-p033w Upgrades

[Tudmonk]

So I recently bought this PC and have upgraded it a bit. I purchased and installed an i5-7400 3ghz and an extra 4 gigs of RAM. I also just purchased a GTX 1050 2gb OC edition. I'm definitely not going to be over clocking any time soon but I just was wondering what you guys would recommend for a power supply. It has an internal 180w which seems to run the current setup just fine I just want something better than the integrated graphics. Do I need to upgrade my power supply or is it fine to run the GTX on top of my current setup? Here's a link to my PC's stock specs.

As you can tell I'm very new to the PC scene and any help would be greatly appreciated.

yeah no the 180w it came with won't cut it , it more than likely only actually makes around 140w.

Any recommendations for power supplies? It needs to be a SFF, I've looked all over for some dimensions and haven't had any luck. Is it possible to have an external power supply?

So I just measured it and the values are as follows. 3.5 inches deep, 2.25 inches tall, and 7.75 inches long.
