Help me with my pc.

Hey guys,

My pc is very old around 8-9 years old with few newer parts that I'll mention in this post and I'm planning to get a pc when I get into a college which will start around May next year, till then I'd like to build a new lower end pc with specs to play Dota ONLY. Its fine if other high end games and programs wont work in this build but it should run dota properly with 100+ fps if possible. So I would like some help regarding this build. My current pc has many problems , the biggest one is that it automatically turns off when I'm In Game without a warning or anything. I have a year old GPU, SSD and PSU that I'm planning to use for this build till I get into college.

Planning to use these as they are 1 year old only.

Gpu- Nvidia Geforce Gtx 1060 6GB

PowerSupply- OCZ ZS 650 Watt

Storage- Wd green 240 GB ssd

Planning to buy these so that it can run dota2 without any problem.

Processor- Ryzen 3 3300X

Motherboard- MSI b450m pro- vdh max

Monitor – Acer Nitro VG240YS, 1080p 144hz .

Ram- 8gb 3200mhz corsair vengeance

Please let me know what you think of this and if I should make any changes.
P.s- My mmr is 6410 ,pos1 player.
