After a series of events (RMAs, OOS, etc.; the works...) I wound up with a 580. I wish I would have known the fan controller I installed would have quieted the case fans so much as I would have spent a few bucks more initially and grabbed the AX750. What's done is done; I'm taking a shot in the dark by contacting Corsair and inquiring (hmmm... more like begging on my hands and knees) if they would swap out my noisy psu for an AX850 (+the difference ofc). Worst comes to worst, I'll hang onto this one for a while until I catch the 850 on sale I guess. Anyway, enough with my sob-story. Thanks!
EDIT: Found it on Amazon for $150 AR shipped
(student prime ftw), should I grab it If I get no response from Corsair or do they generally go lower than that on sale elsewhere?
It's funny because I share a similar story as you.
I started with an HX750 with the same intentions as you, to keep a single card for a good long year or more. However, through a series of events, and several GPU upgrade cycles just this past year alone, I'm now sitting with an AX1200 just so I don't have to go through the doubt of not having enough power again.
For your situation, I've got my fingers crossed for you. Corsair have been a very receptive group through my experiences in working with them, so I would imagine that they would at least be willing to try to reach some sort of compromise. However, if they do decline the proposition, it looks like the current deal on Amazon is the lowest it has been in the past year:
Checking Newegg, their prices are higher overall, so I think Amazon would be your best bet at this point. And if SLI GTX 580 are in your future, I would definitely hop on that deal!
