I have a Corsair CX430, 430w and on the website listed it says this +3.3V@20A, +5V@20A, +12V@32A, -12V@0.8A, +5VSB@3.0A
Will a Sapphire AMD 6850 be able to run with this power supply? 9I also have a Pentium Sandy Bridge G850)

Yes, you're good to go with that PSU. I run the 6850 OC'ed with an Antec 450W PSU. The corsair is a good PSU and 32A on the 12V line is good. $35 with the rebate is a good deal too.

Thanks a lot bro. Sorry to hit you with another question but I was looking at the 7770 ghz edition, is that faster than the 6850? Is the 770 also faster than a GTX 550ti?

Ooh, now you're talking.

Sapphire 6850 1gb 256bit $140 shipped $125 after MIR vs Sapphire Vapor-X 7770 Ghz Edi 1gb 128bit $150 shipped $135 after MIR.

As you can see, the Vapor-X 7770 is right on par with the 6850, however the Vapor-X is the best GPU cooler available OEM along with the Windforce 2 from Gigabyte. This will allow more headroom for Overclocking by keeping the GPU & VRAM cooler. The 7770 is already a champion OC'er but pair it with the Vapor-X and it's very potent combination.



Keep in mind too that the 7770 is from the current line of Radeon's, the 6850 is the old line. Now for a personal answer, I wish I would have gotten the Vapor-X when I bought my 6850, they were the same price.

Edit: forgot to add that the 7770 uses less power than the 6850 giving you more wiggle room on that PSU.

I am kinda on a budget, I am looking at the HIS iCooler 7770 ghz edition, is this one still as faster (it's cheaper). Is this one faster than an EVGA gtx550ti. Thise are my final questions, thanks again bro!

Honestly, if you can flip the extra $15, the HiS 7850 1gb 256bit uses less power than the 6850 and, as you can see on the chart above, is roughly a 38% (1GB) 43% (2gb) improvement over the 7770.

For the same price as the 6850 grab the Sapphire 7770 Ghz Edi OC 1gb 128bit $147 shipped $132 after MIR.

If you're on a super tight budget and want the best card for the least amount of money then the PowerColor 7770 Ghz Edi 1gb 128bit $127 shipped $117 after MIR is a good choice.

Here's the Benchmark comparison between the 7770 & 550 Ti. Yes, the 7770 is much faster. The AMD counterpart to the 7770 is the new GTX 650 Ti which is more expensive ($150) but is faster, uses less power & runs cooler. I don't know how well they overclock though.

Depending on how tight your budget is, here's the breakdown of the price and performance:
$120-145 Radeon 7770
$150 GTX 650 Ti
$165 Radeon 7850 1gb

I dont really trust that brand do Id rather go with the HIS 7770 which is like $3 more. What I do not understand is that on that graph the 7770 is faster but on hwcompare the 550ti is faster. I think I can figure it out from here as to which to get. Thanks for your help

PowerColor has been around a very long time. They are the only ones who make the 7990, no one else has even attempted it. Personal preference is something that can't be swayed though.

If you're set on the budget then the 7770, whatever brand you decide on is the best choice. I strongly recommend trying to come up with the $165 for the HiS 7850 1gb. It is a huge improvement over the 7770 for not much more.

Good luck on your choice.

7770 performs pretty much the same with 6850, it has slightly worse performance in older games, but it is a bit cheaper and consumes less power than 6850. I would also suggest buying 7770 over 6850, and this is the brand I suggest.

However if you can spare some more money, the best bunk for your buck goes to this 7850:

Much better performance than 6850 and 7770, I highly suggest that you buy this one, it worths every dollar. This 7850 is the reason there is no point to buy vapor-X 7770 and the likes, with $10 more you buy a vastly superior GPU.

I'm on a very tight budget because well I'm building the pc, it's either the EVGA GTX550ti or the Sapphire 7770. Whichever is better is the one I'm getting.

The GTX 550 Ti was a good GPU, last year, as it was Nvidia's budget GPU in 2011. The 7770 is the current year model for AMD.

Anandtech's Benchmarks clearly showing the 7770 as a much better performer.

Tech Power Ups Benchmarks showing the 7770 beating the GTX 550 Ti by 18%.
