Couple of questions re: new system build Power Supply Req and Win7 Pro

[Gman]

I'm in the process of putting together a new system order for next week.  I've had my i7 920 w/ 2 6850's in SLI for about 18 months, and it's time to upgrade again.

I'm going with the i7 3820 2011 socket and with an Asus P9X board with 16 gigs of 1600mhz ram.  I've read in a few places that if you're going with 16 gigs ram that having Windows 7 PRO is a better option than Windows 7 Home.  Is there any truth or value to this?  I have Windows 7 currently with my 8 gig system, and I'm just wondering if it's worth spending 140$ on the OEM copy of Win 7 PRO instead of just using my current Win7 Home.  Does the extra 8 gigs not get used properly with Win7 Home or something?  I'd rather not give Micro-losers another 150$ on general principle, so if anyone has information regarding how well a 16 gig system will work without having to go pro, please sound off.

Also, I'm getting a 4 Gig GTX680 vid card.  Will 850 be a big enough power supply with the above mentioned CPU? I'm not going to be overclocking, and neither do I plan on going the SLI route again, so it'll be just one video card and a couple of hard drives, one of them being SSD obviously, and the other just a 2 gig data drive.

Im running 16GB on W7 Home 64bit with no problems. I think I remember someone posting that Home edition only supports up to 16Gb where Pro supports 128GB or something ridicules like that.

850W should be more than enough. that card has a max of 195W and the cpu is a max of 130W

There are several posts about PSUs in this thread:

Partially correct, the home edition supports 16Gb and the pro 192Gb. So no reason to upgrade if you plan to use 16Gb or less. In practical terms even 8 gigs sits unused most of the time.

Please remember: cheap 850W PSU = crap but might be able to feed your system for some time.
Quality/brand 850W PSU = way too big for your system.

I have a similar system as you except I went w/ the Asus Rampage IV Gene mobo w/ 16Gb mem as well w/ all running at stock settings.
I went w/ Win 7 64 HP also due to myself only using 16Gb mem & have no issues w/ it at all.
I went w/ a EVGA GTX 670 FTW 2Gb mem vid card & all is well (curious as to how the 4Gb GTX 680 runs AH)
I also went w/ a Corsair TX850 PSU & have no issues there also.

I will pass on this tip though: consider using low-profile mem modules on the 2011 socket mobos if you are gonna be using air cooling as most HSF's for 2011 socket don't have enough spacing between the lower fins/fan shroud & inner mem slots for the taller mem cooling HSF's. I used the Artic Cooling i30 Freezer HSF on my I7 3820 & the LP mem HS clear the CPU HSF fan shroud by less than 1/2".

Hope this helps.

 

The mem modules that I went with were Corsair Vengence LP DDR3 1600 4 X 4Gb mem kit
