Hi friends,
I am building a new gaming rig. My specs are:
Intel core i5 3570k, asus p8z77 v pro, asus radeon hd 7970 dc2t 3gd5, corsair 2 x 8gb 1600 mhz ram, seagate 2 tb hdd, sony dvd rw.
So, plz suggest me a good psu (corsair/ seasonic) that can withstand the load at 100% usage. Also, can u suggest me a good gaming cabinet for my rig? I think to go with Corsair 400R cabinet. Do I need extra gpu holder to reduce the impact of this mssive gpu on motherboard? If yes then plz suggest me that too.
Hi - If you want to get a 650-750w PSU thet's OK, but unnecessary.
That system will run fine on a quality 550w unit. That's what
realhardtech suggests and that's their expertise. gpu makers
always suggest more than needed to allow for psu's that don't
deliver publ specs and older psu's that might not have sufficient
amps on the +12v rail(s)
To correct bad info given to you, efficiency has nothing to do with
total wattage of the PSU. Efficiency is how a particular PSU converts
electr from the wall to DC power for the components.
example: if your pc components need 200w at a point in time,
a psu that's 87% efficient will pull 230w from the wall, an 80%
efficient psu will pull 250w, and a 70% psu will pull 286w from the
wall, all 3 cases to deliver 200w to your components.
Now, if you're pretty sure you are going to CF down the road, you
might want to get a quality larger power PSU. But, if you are
going to use only one gpu7970, then 550w is more than enough.
No harm in more, but it's unnecessary and is more $$ upfront.
I do recommend you get an efficient unit.
A few to consider:

http://www.newegg.com/Product/Product.aspx?Item=N82E16817139012 nets to $70 " " (prob the one I'd get - prof series)
a lot more prom activity on the 650's, so I'd prob get one of those as they're
less $
