What PSU should i get, i wanna go quad crossfire.

Hey guys i am building my rig but i cant decide which psu to get, ima get the hd6950 since u can change the bios and it will be a 6970. Those cards have two power pins so 4 cards will be 8 pins. let me know what psu to get pleaseee

My budget is pretty thigh rite now, so i was looking to spend like 150 for the psu, Im getting one hd 6950 as of rite now but i wanna go dual then tri and finally quad. But i just dont wanna be changing the psu again. Also are there any other gpus coming out? Cuz thats the problem with computer man, u buy one card today and then tomorrow theres another one twice faster and cheaper lol. i heard about the 6990 but i think thats gonna be quite expensive for me, what do u recommend? a video card around 300 also think about crossfire i dont mind getting a older model if am gonna get better results than a single card. thankssssssss

Heres what i got so far.

My suggestion though is the Corsair Professional Series AX1200 1200W 80 PLUS GOLD Certified Modular Power Supply, it can handle the job.

I agree. A good 1200w should be able to handle four 6950/6970's with relative ease.

The Antec HCP-1200 is the best 1200W power supply on the market. Not cheap at $310, but quality always seems to come at a price...

If you're going to spend that kind of money, why not get a Sandy Bridge? Phenoms are 2 generations behind the Sandy Bridge.C_Rule

Out of the two, get the ASUS. As for quad crossfire from three PCI-e slots, think dual GPU cards. Two 5970's = 4 GPU cores = Quad crossfire.

No. Both the ASRock and the ASUS you linked only do 8x/8x. The only P67 boards that support full 16x/16x bandwidth are those sporting the NF200 chip, which are the ASUS Maximus IV Extreme and the Gigabyte P67A-UD7.

If you're going to spend that kind of money, why not get a Sandy Bridge? Phenoms are 2 generations behind the Sandy Bridge.C_Rule

If he plans on doing 4 videocards then sandybridge would be terrible right now, his lanes would be limited to 4x.

Agreed. LGA 1366 with X58 is definitely the best option for 3 or 4 card configurations right now.

I dunno but is there any performance difference between dual gpu and triple gpu setups and above

Help please trynna buy it tonightangelyoel

I say just get a crossfire setup of 2 X 6950. They're cheaper and perform very well. Either that or the 570 sli

But i dont know if this setup is right anymore since somebody told me that processor is 2 gens behind and i should get those new intel but if i do i gotta change my mobo and that makes it all complicated again since all the mobos ive seen are way to expensive and most of them dont even support 2 video cards at 16x. If i go with this setup i can get two at 16x, and 4 at 8x.

also this mobo looks very good.

Seriously. Who needs more GPU horsepower than that?

Can you guys please take a look at my last setup, i wanna buy it tonite. also take a look at the mobos since i got two there.angelyoel

Go with the Asus mobo. And switch PSU to something like the Antec TPQ1000W. BFG is defunct, so when something goes wrong with the PSU, you've got nowhere to go...

You REALLY don't want to gamble on the PSU, it could potentially kill every other component in your PC. Also, I do hope you are aware that anything beyond regular crossfire is going to get poor scaling and spotty game support. As far as mobo's go, x8 x8 really will not hurt your performance all that much, its usually like 2-5% vs 16/16.Roggirek

It's really up to you. Personally, if I was spending that much, I'd want the latest and greatest. However, if you DO stick with AMD, you might want to drop to the phenom2 X4 965. No games will take advantage of 6 cores, so you may as well save that cash, and use it on an SSD or save for later.Roggirek

How is 1200 watts overkill for quadfire when each card can use well over 200 watts?
