600W PSU Good enough for this build?



Hi - Blackbird linked a decent unit to you. If you already ordered the
CX600, keep it. The people telling you to get 750 to be safe are off base.
The key spec is available amps on the +12v rail, not total wattage.

You need only a quality 500w(with min 30a on the +12v) unit to run that sytem with headroom.
The cx600 has 46amps on the +12v rail which is more than enough for your system.
