Is it safe to connect 4 fans into one system fan header?

Each of my case fans have an amperage of 0.25A. And I am not sure how much amps max that the sys fan header of my mobo can handle. (ASUS H110M-D)

Assuming that the maximum amps it can take per fan header is 1A, if I put 4 of my case fans (0.25A each) into the sys fan header it would equal to 1A. Is it safe to have the system fan header at its amperage limit? Or should I instead connect one of my case fans to my psu with a molex adapter so it will be 0.75A?
