Hello guys, Im new here and i do have a question. i have an old group of pcs that they need a power supply, and im not sure which one and how many watts.

RIG:
CPU: Intel I7 3770K
Ram: Corsair Dominator platinum 8GB (4x2) 1600mhz
GPU: Asus GTX 760 2gb DC2OC
HDD: WD 1TB black caviar 5400 or 5600 rpm (i cant remember well)
Mother: of course Asus Sabertooth Z77
CPU FAN: Corsair H80i
Case: thermaltake chaser MK-1


now i was thinking in get a power supply Corsair RM1000. but im sure if that is too much.(consider i need to buy 5 psu and with aircon not sure about the electricity stability)

* I do not want to make OC my CPU or GPU (maybe just a little)
* i am not considering in add another GPU (perhaps in future not now)
* i am planning in use windows 7 64 bits

NOTE: I just want a power supply that can works with my rig and the components works well and stable. considering that i have few corsair components a Corsair PSU should be fine. but you guys can recommend another brand or model.

NOTE2: Corsair now have RM1000x and RM1000i. im not sure what are those differences compare with the previous RM1000.

Thanks in advance and anything just let me know.
