It depends.

The connectors and rails are seemingly "normal" ones, but the overall power is on the low side, 305 W total, 150 W on 3.3/5 V and 264 W on 12 V is not that much.

You need to calculate the power requirements of your motherboard+processor+other stuff, there are online calculator for this, examples:

The most complete/detailed should be:

 in "basic" mode should give you an idea, the "expert" mode is needed to have the details of the expected power requirements divided by voltage rails.
