<p>I have a zotac ion a with the built in psu. I use only a sata to cf adapter and cf card as local hd for booting into xubuntu / mythbuntu.</p>
<p>I would be surprised based on my experience of silent psus if the built in unit was sufficient for two 3.5 drives and an optical drive. You'll probably find it will just not boot. I would expect that the psu rating and max amps on each voltage is in the user manual whcih can be downloaded from the zotac website.</p>
