Prontus :
Thx for the quick answer. I was worried that the card is not getting enough power.
Well now that you mention it that Zalman psu is an unknown to me, im guessing its likely pretty low quality. It has enough power but I would not trust a psu like that and my system, no professional review I can find and the OEM of that psu is Hui Cheng Electronic Technology who I have never heard of. I would be weary of that psu.
