The short answer is yes; the power supply is not adequate. My 400 watt
Antec PSU has better current output, as will any decent quality PSU. A
cheap generic PSU is a good way to ask for trouble and/or catastrophic
failures.
Suggest an Antec, Enermax, or other good quality PSU at least 430 watts.

You need stacks of AMPS on the +12v supply, 18a being the minimum..



Just look at what these can give..
