Will a OCZ 850 Watt gold certified PSU enough wattage used in crossfire? CPU-6core AMD Zambizi, lots of fans RAM-G Skill X series 16 gB

I have a similar setup but 1000 watt. Doesn't seem to tax it at all so 850 might be enough.

When I purchased this graphics card, I had a 500 Watt power supply and had problems getting it to turn on. I replaced it with a 600w power supply and it fixed the problem. You should be good with the 850w power supply but I'm not sure how it will work in crossfire mode. It's a great product and I highly recommend it for prospective gamers

Not sure how well CrossFireX will scale across 4 GPUs. I personally have a 1200w PSU for one of these cards. According to Tom's Hardware the card only draws 450w at full load. Can't link the article at the moment on my mobile.

You may need to upgrade your power supply. The chip manufacturer (AMD) specifies the following: PCI Express based PC is required with one X16 lane graphics slot available on the motherboard 500W (or greater) power supply with one 75W 6-pin PCI Express power connector recommended7 600W power supply (or greater) with two 75W 6-pin PCI Express power connectors recommended for AMD CrossFire technology. Certified power supplies are recommended. Refer to http://ati.amd.com/certifiedPSU for a list of Certified products Minimum 4GB of system memory 8GB (or more) of system memory recommended for AMD CrossFire technology.

Late answer, so I hope that you haven't had any problems. At full load, this card can consume up to 350W. I wouldn't go less than 750 for a PSU. If you plan on an OC, I'd go even higher. That being said, my CPU, GPU, and RAM are all OC'd. I've also got four HDD and one SSD, five case fans, and a 1050W Corsair. If you're considering spending this kind of money, I'd feel better knowing that the PSU voltage isn't going off course due to an overload, or that the PSU killed itself without taking casualties (fingers crossed).

400W or greater for single performanceand 500W for amd crossfire performance

I'm using a 430w Corsair cx power supply with a gigabyte r9 270 (note it uses 2x 6 pin instead of just one ) and its been running normally i am even able to overclock it without hassle. I'm even thinking in adding another card to crossfire. If you think 500w is not enough (which it should depending on what type of psu it is) you should look at this video: http://www.youtube.com/watch?v=ajiN9aVOv4A this is a high end power hungry build and it still barely even manages to get to 400w while STRESSING EVERYTHING INCLUDING CPU AND GPU TO THE MAXIMUM!! There is no need to get another psu, yet once again, i do have a 80+ bronze gpu and its rating do make it seem very reliable.

This is an AMD card. I think that it can be crossfired, I see a connection near the top left of the product picture. Although I have read somewhere that you will need at least a 650W power supply.

you will be perfectly fine i have a 430 watt psu currently and i never even get near t going over that. this graphics card uses only about 80 watts on average. The only time you need to worry about wattage is when you get higher end cards or more of them.

The power needed for the CPU should also be considered. I read somewhere that MSI recommended 500 watts for a system with 1 card. Since you are overclocking the CPU?, and the GPU?, I would recommend a 850 watt PSU at a minimum just to be safe and avoid power issues. Have fun!

It will power your system without an issue. With those specs I would suspect even a 500 watt PSU would work but if you plan on upgrading in the future or putting that video card in Crossfire you would want the 700 watt. Here is a link to a a PSU calculator that should help you in the future, http://www.coolermaster.outervision.com

Yes sir. I am currently running 2 x AMD 7870's on it very nicely. The second PCI-E rail is even at 16x so should work fine with any crossfire set up.

Personally, I like to have a little more than required so i would go with an 850W PSU, so to answer your question, yes this one will work fine. You could also use a 750W PSU as well though.

That depends on what other components your system has. There are wattage calculators online that can help you estimate your systems usage. Is your pus rated bronze or gold or have a plus symbol on it? I'm running an Intel i5 2505 low wattage processor, 4gb or ddr3, SSD and that is about it. I have a 250W+80 bronze with this card and she runs like a dream.

You always get this kind of info from the mfr. BTW, SLI is Nvidia, Crossfire is AMD specs at site:http://us.msi.com/product/vga/R7950-TwinFrozr3GD5-OC.html#?div=Specification

In the context of a standard PC desktop/tower build, you can get away with a 500-watt PSU if you stick to a single graphics card setup plus optical drive and hard drive, a couple of cooling fans, etc. Anything beyond that and you'll need more capacity. For example, if you're a gamer and want to run a dual-card SLI graphics card setup, that alone can chew up to 300 watts under heavy load, leaving little operating margin for other significant loads such as the main CPU, etc. On my own build, I went with a high-quality 850-watt PSU from Corsair. Although I'm only running one MSI GTX 760-based graphics card right now, I have enough power supply capacity to add another card at any time without worrying about straining, even though I'm moderately overclocking my Intel 4770K quad-core CPU (to 4.3 Ghz) and have installed a liquid cooling system and four power-efficient cooling fans. I estimate that my system draws a maximum of about 400 watts when running a game (including all my drives and peripherals). The PSU's internal cooling fan rarely kicks on, which lets me know I'm letting the PSU loaf most of the time. Keeping a PSU cool and in the middle of its rated supply capacity also helps with power efficiency. In conclusion, if you know you'll stick with a single graphics card, go with one rated at 650 watts for peace of mind. For two cards, I would go with 850 watts. I know that some people will think my recommendations are a bit of overkill, but as someone who's had to replace a couple of PSUs in the past because I tried to save a few bucks by shaving power margins, I'd rather pay a bit extra for peace of mind. Note that many hardcore gamers won't settle for anything less than a 1.2KW supply!

The recommended system specs for this card is a 750 watt power supply. An 850 will do fine.
