Wow. I wasn't expecting that.
I've never heard of that manufacturer before in my life! Why did you skimp on the PSU when you built it (unless if it was prebuilt)? Always get a good quality PSU when you have fairly power-hungry components.
And sorry to 'SPAWN OF II' for not understanding from your viewpoint.
