Windows 7: is my system under powered?

I found this one
Newegg.com - CORSAIR Professional Series HX850 (CMPSU-850HX) 850W ATX12V 2.3 / EPS12V 2.91 80 PLUS SILVER Certified Modular Active PFC Power Supply
it doesn't say crossfire/Sli ready, but it has 6x 6+2 connectors, why would it not say crossfire/sli ready?
do you think this would go well with my system?

This is on the main overview page.
Attachment 165966

Also choose one large enough where it is only pulling 60% of it's maximum. It allows for aging. expansion and does not overwork the PSU so it will run cooler and last longer.

BTW, that PSU is an excellent choice. It is the same PSU I have, I just have the HX750.

There are also 12 SATA and 12 Molex connectors so you can connect multiple drives and peripherals.
Good choice on the PSU, I have the HX650W and I'm considering going to the 750W. Newegg offten just uses whatever the maker has on their site.

Gary, I have both the HX650 and the HX750, if you go with the 750 you will not be sorry.
In kalelreturns case, you did the PSU calculations, do you think 850 is big enough?

I'm sure 850W will be fine and give about 20%-25% headroom so he can play about any game.


EDIT: I'm not thinking right, the 850W, based on the 706W calculation, would put you 32W under the recommended 25% overhead. Either of these would be good, based on how much you can spend. You won't be OVER powered, the PSU will output what it needs to.

how did you get 950-1000w? I thought 850w would be plenty. Would 950-1000w give me some room for a video card upgrade?

Yes it will. It will also make your system cooler and not overwork the PSU, thus making it last longer.

another thing I forgot to mention was that sometimes when I put my computer to sleep, and try to wake it up, it wont display anything, the computer wakes up, but nothing sounds like its actually waking up, if that makes sense. its pretty much the same and when I try to turn my computer on, it will turn on, but doesn't boot. Also, when I woke my computer up today it showed my RAM usage at 95% and my computer was really slow, I looked at the task manager, but it just showed the majority of the usage on whatever program I tried to pull up. Even with all programs closed, it showed task manager at 95% usage.

Ok got another BSOD

072011-18049-01.dmp.zip

its pointing to my memory again. I ran memtest again with just one stick of RAM overnight and found no problems. I will test the last stick tonight. Looks like a software problem? Also Last night my computer was crashing really bad and wouldn't boot, so I looked in my computer and I noticed that the 4 pin connector on the 20+4 pin cable wasn't fully connected to the motherboard. it turns out that it was inserted incorrectly. I didn't noticed that it had little notches on it indicating which way it was suppose to be inserted. My bad. however, after I fixed that, it still wouldn't start up. So that could have been part of the problem.
