Sigh, I have too much to learn.

I used to think that if someone said "this 750W is just a generic 450W" that it could only mean that they were referring to a low +12V capacity and nothing else.

So, I'm glad I asked!

the HX850 will be more than enough, leaving you plenty of headroom for overclocking and the like. You could run that system on the HX750 if you wanted to.

Ya frys put it together for me. they will swap it out for me with a Corsair 1000hx or an Antec 850 true power quattro. I suppose I could do it myself.

the PC did just shut off on its own on saturday night just idling. i left it on and got dinner, and it was off when I came back. I thought it did an update, but when i turned it back on it went to the screen where it said improper shut down detected and gives the option to boot in safe mode. The weird thing is I had it on for a few more hours after that gaming and nothing happened. It dose worry me a little that something went wrong and I dont know what made it shut off like that just sitting there.

So I think I am just going to go back and have them put the corsair 1000hx in this weekend. they do it for free so no biggy. I just dont want to mess up the wiring and plug the wrong connectors in the wrong places in the motherboard.

It's much easier than you might think - especially if you built the system.



But again, a high quality 750W power supply would be enough to power your system if it had two 6970s in it. One such PSU is the 750W Antec TruePower New.



If you've never done it before, then are you saying that someone else built your system for you?



Edit: here are some signs (taken from Guru3D.com) that the PSU is unable to handle the system:
  • bad 3D performance
  • crashing games
  • spontaneous reset or imminent shutdown of the PC
  • freezing during gameplay
  • PSU overload can cause it to break down


However, some of these behaviors can be caused by other things too.

Why are those two PSUs the only options? Why don't they let you pick something else?

Based on what GameBoy just taught me, I am more inclined to suspect that PSU now.

Or the Corsair HX750.

Or the 750W XFX "XXX" edition, or the 750W "Black Edition".

A quality 850W would be overkill and unnecessary.

Well If I can take it out myself and put it back in with no real worry than i may just find a 750 otherwise I am stuck with what Frys has. The thermaltakes seem to have good reviews and a reasonable price.

It is much easier than you might be thinking. It's so easy that the worst part is the little bit of physical labor.

LOL, I believe you. I will just do it myself then. If Ican take apart a motor and put it back then I can do this. i just worry about static. So would the Thermaltake toughpower 875 be a good one. i know a lot of people say their other line of PSU's are crap, but this one is left out and said that it is good. Otherwise I will get the Antec truepower quattro 1000w they have. The 850's are gone and discontinued they said so are the corsair 850's and 750's. May just be discontinued from their invntory only though. If the Thermaltake 875 toughpower is a good one I can get it from Tiger direct for 139.00 with my coupon.
