150mm is likely the common standard for the fork, but it is not QR and instead thru axle (the manufacturer's info there is confusing)
The most popular fatbike axle width is now 197mm for thru axle and 190mm for QR to accommodate larger tires
I suspect you have 170mm QR on your frame since it is not thru axle. The fatbike standard for thru axle in that range is 177mm and won't fit your frame.
Snap a few pics and we can probably be more sure and more details on the bike as well.
