Used Pc for Fortnite?

Want to assemble a very cheap used pc for Fortnite.

Play in 900p LOW

should be able to run at 60 fps

want to get away as cheap as possible which components would you recommend to me

If you buy them second-hand, of course, the best would be graphics cards that do not consume more than 75 watts then I can install them more easily and do not need a strong power supply, but they do not have to be

I would recommend the GTX 1050 Ti as a graphics card, it is not expensive and draws little power, does not even need a power plug, just put it on the mainboard and you're done. This means you can also play in Full HD with 60FPS.

Fortnite at 60fps is unfortunately felt unplayable

With the 1050 ti you can achieve a low of 120 fps or more is not necessarily the best way to save money. Games only in 900p anyway
