I'm not sure what kind of budget you are on, but I would consider at the absolute minimum a 650 watt PSU. Each of those cards can draw 170 watts alone, so that is 340 on gpu's alone. I would suggest that you go with a 750-850 watt power supply instead for a little security. You should also make sure that your power supply is produced by a reputable company. I use corsair personally (which is just a rebadged seasonic unit), but there are other good manufacturers out there.
One thing I would consider, is the corsair HX850's have silent fan options. They only run if its pulling enough load to heat up. If you think about noise alot, they "currently" are smarter then there AX series, except there AX***i series.
Also, whats the budget for this build. That processor is less powerful then a 2500k. You do not at all need 32GB of that fast of ram (unless you render alot in which case that CPU is going to limit that), and those graphics cards are a little out of date.
@TallGeese. The bugest is next to unlimted as I have this amazing thing called a job ;)
Jokes aside, most of what I'll be doing with this machine is streaming recently released games, and I plan on doing that on max settings, making the veiwer experance better. Aswell as still having a good upperhand on games which are not yet released, being able to play them at maximum settings right from the get-go
So chould say I do rendering, most of it is just compiling Fraps files into smaller ones, while keeping the quality. And from time to time a mixup of the games I've played on stream.
But overall, this will be a gaming build rather than a rendering build
This is a pretty good resource for estimating consumption, ust take the value it spits out add 50-75 watts, then buy what you need from silverstone/seasonic/corsair
This is will have a much longer life cycle, and will destroy recent games. Its a small bit more for a processor that renders a fair bit faster as well.
First of all.. I'd love to see you run you GPU HD 5850 in SLI
Second of all dont just get 2 5850 just because it looks cool to have 2 graphics cards, it'll get hotter, use more power and it wont give the performance you're paying for.. oh and one more thing 5850 sucks.. you can get a laptop with 5850 for $400, and with Crossfire (which you call SLI) you'll only get like 15% more than a with one 5850 so that's just bottlenecking like hell :P
I would advice you to get something like 7870 or something that might be $50-$100 more but I couldn't check the price for 5850, they dont sell it on newegg because it's outdated.
And for the PSU xD
I'd say get a 500-600w unless you're going for the 5850 crossfire solution (Which I dont recommend at all) then get a 750-850w
Yea.. I would suggest XFX because of the better cooling and good price. But everyone have different taste and ASUS is also great! And I mean that card will take any new game like BF3 maybe only 30-40 fps. But as long as it's over 30 fps it's playable :D
