Depends who "they" are.
So was this a barebones case/PSU/motherboard and you added all the rest? Such packages tend to have minimally adequate PSUs for a basic system. Depending on what you added, it may or may not be adequate.
Please list all the system components. Also the +12V, +5V, and +3.3V amperage ratings from the power supply label, like this but using your figures:
You can try a minimal configuration (1 stick RAM, no drives, no cards except video) and see if you can boot into BIOS.
