That's actually a 750W PSU, Thermaltake uses the peak rating to come up with 850.

I would recommend something from Corsair such as TX850 or HX850. And also 2x 4890 instead of 3x 4850; lower power consumption but better performance.

I already have the thermaltake and dont want a cosair because i try to be different. And how do you come off telling me this is a 750 watt amp when it clearly says on the psun850 watt peak and is listed as a 850 watt psu. Explain to me if i am wrong or someone else explain please, but i know for a fact this is a 850 watt psu.

Some PSUs are rated by the amount of power they can deliver continuously, without any trouble. Corsair PSUs are like this. A Corsair 850 can deliver 850 watts while at 45C or higher, and will not fail no matter how long it remains at this level. Others (typically lower quality units) are rated at the peak power they can deliver. Your Thermaltake is like this. It can deliver 850 watts, but it can only deliver it for a short time. It is only capable of 750 watts continuously. As for trying to be different? That's all fine and good, but is it really worth sacrificing quality just so you can be different?

But i was told this is a great psu and i paid $150 bucks for it.

Here is a chart on video card power. You just need to google "Graphics card power consumpsion. The just added in the power requirements for the remainder of your system. ie 3 4850's would require 3 x 110 Watts = 330 watts in addition to your MB and CPU and HDDs plus DVD drives. (+ sound card if you have one). So a GOOD 850 would probably be fine. key word GOOD.

cji and the theanimal gave you a good input. You should have done some research as to the quality. There are some sites that give and UNbiased evaluation.

No when to hold them and when to fold - O that's poker

Since you already have the Thermaltake, I don't see any reason to ditch it. But should you ever buy from Thermaltake again, the best line from them is the Toughpower. Both the Purepower and TR2 lines are lower price, lower efficiency, and just plain don't cut it compared to the Toughpower line. Yes, you do have a 850wt PSU, technically speaking, but it won't hold up to delivering that 850wt for long periods of time. At its low efficiency, it will also burn up a lot more electricity than the Toughpower line.

As the Chief said, there are websites for checking out what is a good PSU and what isn't. One that I refer to is http://www.jonnyguru.com/index.php By way of comparison of the TT Toughpower and the Corsair TX850wt, they both use many of the same internals, to quote from Jonny's review of a Toughpower 850wt, "Ah, Mr. XT... I knew the second that I saw you with the lid off I was dealing with a CWT PSH design. This could very well be the most popular CWT design ever by now, with the likes of Corsair, Xigmatek, I-Star, and about a kerbillion others all using this platform." What's that, both the TT Toughpower and the Corsair use the same internals? That's right, so the next thing to look at is price, that is, which is cheaper when you go to buy. I have a TT Toughpower 850wt in one of my computers and it has done very well, no complaints about it at all. I also got it on a very good sale, so I didn't pay very much for it. I also have a couple PC P&C 750wt PSUs and an Antec Signiture 650wt, so I don't consider myself a fanboy of one brand or another. As the Chief said, there is a difference between a Good 850wt PSU and a plain 850wt PSU.

Chief and Sailor thanks guys you explained and broke it down nice for me. Now listen in my current computer i have the 850 watt antec true power quattro you guys think i should swap it with my thermaltake tr2 for my new build since i will be using more hardware in this rig???? Now that i read both psu's i see it says on the qauttro it seems to deliver the full 850 watts.

I've been using the Antec Quattro 850 for two and half years, no problems. Only using 1 4870 GPU, 4 HDDs, one DVD writer and one Blu-ray writer. My Cpu is a lowly E6400 @ 3.2 GHz. So that is only about 350 Watts Max (using a power meter).
