I really don't think so unless you are doing some serious overclocking, but it would hurt to check it out.
Also, while you are at it, are your chipset and video drivers fully up to date?
No overclocking has been done so that's not it then. I know that a 4 pin should be enough to power, but was hoping I'd miscalculated. Also since the 4 pin is connected to a dedicated 4 pin port (not an 8 pin) I thought that may be a further issue. I know that some people would call this a "Tertiary" port (or something like that). But I'm fairly new to this stuff.
With regards to drivers, is there any way to tell for sure? I recently re-installed windows so I may have missed one or two. Thanks
Sorry for being so new!!
