Need advice on how many SSd's i can install

[Maloy]

PSU - EVGA 650w

CPU: Intel Core i7-7820x

Motherboard
MSI Pro Series X299 Raider

Currently connected is:
4x 8gb DDR4 RAM
Samsung NVMe SSD 960 Evo M.2 250GB
1tb HDD
1080 TI Graphics card


Hi, I really need some help I hardly know anything about pcs. Recently my SSD keeps getting full so ive brought a 970 EVO Plus NVMe M.2 . I was wondering can I connect this on my motherboard too? So have 2 ssds and the HDD.

(I know my board has 2 slots, one is hard to get too because the graphics card covers this , but i think i am right in saying i can unplug the graphics card install the ssd and it will be fine ?.)

Thank you
