Another is it going to be enough thread

post #1 of 4
Thread Starter 
Okay so I used the power supply calculator Phaedrus put together and I have a question on how to perceive the results of this application.
I'm planning a future rig:
IB-E (chose Sandy Bridge i7, presuming power draw should be similar, +40% overclock)
High end GPU (chose GTX 590, its not likely I will choose a dual-gpu single PCB solution, but it is the highest single slot power draw)
High end PhysX (probably going to use one of my two current GTX 460s for this, so I chose a GTX 460)
4 Conventional platter drives, a single solid state and optical drive, and 5 fans (I chose 7 to compensate for the fact that I will have a pump running)
The calculator spots me dead on 850w with folding ticked.
The case I am using has some serious space constraints (6.3-6.4" in PSU length at a maximum, a 850w SeaSonic X series is exactly 6.3" in length) but I'd like to keep it this compact - is it saying 850w will be pleanty for the system I am building, or that the system I am building will PUSH 850w to the limit?

Should I be fine with a 850w gold power supply supplying the parts I selected above (granted, we don't know just how power hungry IB-E will be yet, although its probably going to be as hungry as Nehalem or SB-E.)
I'm probably going with the most high end single GPU Kepler solution, and coupling it with a 460 for PhysX and I'm probably going to have 4 sticks (or 8 if theres a motherboard out for it) of ram. the size constraint is due to my lower radiator being less than 1 inch from the power supply, much more than 6.4" and its going to be putting a lot of strain on the wires. and past 6.55" I doubt I could even get it to fit without further modifications (I may be able to push another inch out if I modify the case a bit more, which would give me the opportunity to install a 1000w gold power supply and have no worries, but I'd rather not have to unless an 850 is insufficient)

A 850w SeaSonic X series should handle it fine like you said. A 750 watt can power a pair of sightly overclocked 580's and an i7 lol. So a 590 and SB-E on a quality PSU like that will be fine.

850w gold rated should be fine. Wouldn't hurt to over kill it a bit though, at full load overclocked it'll draw 700watts + easily with 2 GTX 580's I'd say
