My specs are:

be quiet! S6-SYS-UA-450W
Medion P6300 MS-7646
AMD Athlon II X3 440 @ 3.00GHz
4GB DDR3
No GPU ATM
500GB HDD

I am interested in buying used ZOTAC GeForce GTX 570. Can my power supply handle it? Will play only Fortnite.

The spare you have should do. But i'd consider rethinking the 570 with a 750ti or a 1050 since they're a lot nicer and the 570 looks to be an 8 year old card
