Your GPU can draw up to ~150W (i.e., ~12.5A at +12V). Your CPU can draw up to ~95W (i.e., ~8A at +12V). RAM (assuming 2x) can draw up to ~5W, HDD (assuming 1x) can draw up to ~30W (start-up +12V power), and Fans (assuming 3x) can draw up to ~12W.
So GPU + CPU + RAM + HDD + Fans would be around 150W + 95W + 5W + 30W + 12W = 292W (i.e., ~24A at +12V).
Add some headroom for other components connected to the PSU/motherboard around ~30W (assumed value). So, you'd be looking at a theoretical calculated power draw of about ~322W (i.e., ~27A at +12V), with assumptions/headroom.
As your FSP PSU can provide a max. combined power of 360W (i.e., 30A) at the +12V rail, you may be pushing your PSU to its limits given the above theoretical/assumed calculations as peak load may use up to 90% of the rated +12V power your PSU can provide (but still safe, given the assumed values).
I would not OC or connect too many components personally using that PSU.
