It's the grey labelled CX unit, correct?
If so, you should be fine I'd have looked into a higher quality PSU, 750W unit( or higher due to transient load spikes). Just make sure the components you're buying have the necessary number of connectors as your PSU.
If your PSU lacks said connectors for your parts, you either have;
a| the wrong parts for your build
or
b| the wrong PSU for your parts
Please stick to one thread.
