Which Corsair PSU, Should I choose?

[deathstalker99]

Hey Guys

My Rig Specs are as follows

ASUS Rampage 4 Extreme
Windows 7 Ultimate Edition
3930K I7 running @ 5GHZ
Kingston Hyper x 8GB x 4 @ 2100MHZ
512Kbps x 2 Corsair SSD
1500 Watts Thermaltake PSU
EVGA 780 TI SC x 2
Case Corsair 900D

So couple of days back i was having some issues with my 2 x SLI SC 780 TI's. The issue was solved thanks to 2 gentlemen. However they recommended to change the PSU. I saw three PSU's which i thought where good

AX1500i Power Supply

HX1050 Power Supply

RM1000 Power Supply

Know the question is, which one should i go for. As all that technical mumbo jumbo did not make any sense.
Appreciate ur help guys

AX1500i is serious overkill, you could easily get away with an AX860(i) or RM850.

If it put your mind at ease getting a higher wattage unit, then I'd say RM1000.

Both the rm1000 and hx1050 would supply plenty enough power to your rig with headroom left for future upgrades. i think that the ax1500 would be a BIG overkill. I mean you can power a 295X2 with that

the hx series has a hardwired 24pin which you may not like while the rm is fully modular

OK. Looking at your consideration, i ll go for the RM1000, as i would prefer better watts.

Finally whats the thought on the AX1200i

Id go for a AXi model instead of the RM. The AXi is a much better built power supply and will perform better and last longer. The AX860i like mentioned would be perfect. If youre hell bent on PSU overkill (and there isnt necessarily anything wrong with that) the AX1200i would certainly be a great choice but youll be paying for a lot of capacity you simply wont be using.

The ax860i has a peak voltage of 1008.8watts
I would recommend an RM1000 it should come at the same price of an ax860i and can actually handle the loads better
A friend of mine has 2 780tis on a really high overclock and his 2011 i7 also overclocked on a hx1050 that could also work for you
