Is it enough for 2 way MSI GTX 970 Gaming 4G(specs tells that this card requires 500W system power supply)? with Corsair hydro h105 cooler and 9 fans?

Should be plenty. NVidia GTX 970 cards only require max 165W of power. You should be fine with 850W.

I got retail box and all the connectors are there. But not all the power supplies are ready for this card. I use high-end power supply. Therefore I didn't have a problem Make sure you have a power supply compatible with two six pin PCI power connectors. You should be running 600 Watt power supply at least. With two separate power channels and six pin connectors on them. This is not a power-hungry card but reliable power supply is very important.

the wattage should be fine but you also need supplemental power plugged directly into this card from the psu.

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!

I have the 650w version. It says on the box that could run two 75w graphic card and a 50w cpu. I have only one gtx 250 sli, with like 10 fans and several lights. It's running fantastic. However yours will require around 700w for two of those cards. I would recommend getting 750w for overclocking or even more expansion down the road. I'm jealous btw I'm sure that card is awesome.

It depends on what you're really planning to run for your video card. I use this card with two Radeon HD 7790 1GB cards in CrossfireX and it runs fine. But if you were to go any higher than that with video cards, you're going to want a bigger PSU.

I'm not sure, but it can't be much. I have it running in a 250w slim desktop system. Seems fast enough, but the fan noise is pretty loud if you run any sort of a game that uses the graphics.

it is. on the safe side i went with a Antec TruePower Quattro 850W Power Supply. this graphics card requires TWO 8pin adapter for ultimate performance capacity.

The card at max usage requires about 140W, so I think with a 450 Power Supply would be fine for a whole system.The card require only one extra PCIe power supply connector. My previous GTX260 requied two.

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.

Go with a quality power supply like a 300w seasonic and you'll be fine. Always go name brand on a psu. Never go cheap. A 430w power supply will give you a little overhead to add a graphics card in the future if you want to do dual graphics, but even 430w will be overkill if the card can run off of the pcie bus.

Of course it will run your gear, with 750w of power will be enough for SLI or CrossFire. Just make sure that the power supply has the 6 pin connectors that your video cards will demand. But when it comes to power, 750w is fair enough.

That should be fine. I'm running a 500 watt right now with this card, which would more preferable for future upgrades.

It has the proper connectors to do so, but if you're using a 7770, this probably isn't the best power supply to use. While it's rated as a 500W psu, that's only peak output. I believe it actually averages about 380W to 425W. I would recommend looking at Thermaltake or Coolermaster for one of their 600W+ power supplies for a better experience. That said, this power supply is cheap and sufficient for most computing needs. For gaming, do like I suggested and spend a bit extra for a better, higher-wattage power supply.

Yes, 500 watts should be more than enough. Make sure that you use a decent brand name PSU.As mentioned below, if you are running a massive overclock on the CPU or try to overclock the GPU then you might run into some issues. On stock clocks and with a normal build you should be absolutely fine.

It depends on the other components in your system. I run a 450w power supply with this card and no issues. If your CPU is sucking up more than average watts you may require more , but this card has a very low power requirement considering pretty good performance.

That would definitely be enough for 2 or 3 of these cards in Crossfire. 3 might be pushing it depending on the rest of your rig. I would suggest googling power supply calculator and checking your build if your are going with 3 cards.
