I guess I'm worried about all the negative comments I've heard about the new models. It seems a lot of them have that coil whine.
Well, I want to leave room in case I want to upgrade to SLI. I don't need that much power. However, from what information I've found, there is no detriment in having a 750 watt and only using 400 watts (other than the purchasing price).
I would appreciate personal experiences with any models listed, or not listed here.
