Will gtx 1050ti fit in my pc

Solution
Kinda. Can that case use a full height card or does it require a low profile card? Pretty sure you need a low profile card. There are low profile 1050 ti's but they tend to cost more, if you're willing. You could also go with a low profile GT 1030. Not near the horsepower of the 1050 or 1050 ti but still tons better than the factory stuff you have now. Cheap too. Make sure your power supply can handle whatever upgrades you go with.

If you have the Mini Tower a full height card will fit, and the PSU should be OK. Some 1050s come with an uneeded 6 pin PCIe cable, this would force the purchase of a new PSU, avoid them.
There aren't many people upgrading this system. The CPUs it supports are excellent. The 1030 is pretty lame. Not having to buy a PSU could justify the jump to 1050Ti.

Just for comparison i'm including some Opti 780 builds with GTX1050/1060 GPUs so you can see the differnce they can make in GPU scores.

Don't worry if you have a 255W PSU. It's the high efficiency replacement for the old 305W PSU. It can power the 75W PCIe slot just fine.
