First off I know I have asked a similar question, but some things have changed since then. Please let me know if I have broken any rules or anything. My current rig is in my sig. I am using a Corsair TX750v2 and it is working wonderfully. I just upgraded to the Xigmatek Elysium case and I want to get a modular PSU at the same time. I am selling my TX750 to my friend for $70 because he is one of my best friends and I had a question as to which one to replace it with. I am going to stick with Corsair, but I am debating between the AX750, HX750, AX850, and HX850.
I will be upgrading to the FX8150 once it comes out and it is rumored to be a 125W TDP. I am also picking up a second HD 6950 in the near future unless I hear that the 7000 series will be out very soon. I'll then crossfire 2 of them if that is the case. A CPU, GPU, GPU water cooling loop will be in there as well. I just wanted to see if the AX is worth the extra money compared to the HX and if I would 750 or 850. I have read that 850W should be enough for all of that, but let me know if I need to bump it up to a larger size. I don't mind spending the extra on the AX as long as it is really worth it.
