I currently run one of These cards as well as an i72700k. I want to cross fire two: Will I need to up my PSU from 750W to 1000 ?

i would just to be safe says it needs 500w to run one cant say you need another 500w for the 2nd one but having the extra watts wouldnt hurt you
1539107
I would... if you plan to OC, things need more juice. Plus it never hurts to have a little more on reserve if you ever find yourself wanting to add something.

The card calls for 550watt power supply minimum on the box. I run a Corsair TX650 to power it and my hardware with a i5-3570k CPU. I think a 750watt would work well if you want at least that. :)

You should be fine I have two in my system with 5 hdd and blue-ray drive and an i7 CPU running 750 and it runs great!

John, I'm sorry. It turns out that the problem with my computer was unrelated to the card. As for upgrading your PSU, I'm not sure if I would be able to give you useful advice.

It all depends on the 750watt PSU you have. If you have a gold rated high performance name brand PSU it will probably handle it. You will need 4 PCI-E video card power connectors. (6 prong connectors for video cards). You will be pushing a 750w PSU to the max under 100% utilization. If you're just playing games or doing graphics/CAD work and you have a top notch 750 PSU you are probably okay. If you're bit mining and running full throttle 24/7 go for the 1000w PSU. A good indication is, what's the brand and rating of your PSU and does it have four pci-e power connectors. Do not try to use adapters to create more Pci-e power connectors - they fail under full load. It all depends on the 750watt PSU you have.

No, you do not need to as long as your psi has 2x free 6pins adapters for your 2nd gpu. You should be fine.

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

Hmm... I think a 500W PSU would be ok, but are you overclocking the CPU? If so, then I would recommend checking the necessary wattage for the GPU. I'm using a 750W PSU, but I think other people have used less. I would research this further since I'm not 100% sure 500W would suffice. I'm sorry if I couldn't be more helpful.

Considering how this psu failed in 6 months when i have been doing heavy duty gaming.. I think the answer is no. But if you were asking if this unit can supply enough wattage for your build, the answer is yes. UNLESS you are running SLI/Crossfire, in which case go for an 750 or 800W.

I assume you mean power supply wattage. Recommended is 500 watts. If you are ever going to crossfire you you probably want at least 650. I have a corsair 500 watt psu with an overclocked fx 6300 and this card ocd to 1050 core and 1450 memory. Also have 1 tb hdd, blu-ray, card reader, and 8 gb 2133 ram. Everything runs great!

The PSU has 2 six pin plus 2 connectors on the same cable. I used it to fire up a i7 920 with 1 HD6450, powered by the board. there was not enough juice. Removed it, and have not found a use for it yet. You should be in the market for a single rail, 750-800 watt, with 60 plus amps on it. This power supply doesn't produce good numbers after 35% load.

I have a 750W PSU, mainly because I plan on getting another one of these. I bought it on TigerDirect because Amazon couldn't ship it. This GPU is rather awesome. As far as I know, with one of these, I use about ~350W of the 750W PSU.

Considering that on average, while running newer games on Ultra settings, I'm only using a total of around 330 watts, I would say it'll probably work. On the other hand, there's literally no reason to use two of these in SLI; even with just one I can run any new game on the highest possible settings in every area and still get 60+FPS. The second card won't do anything.

Yes, i am running 2 of them plus a i7-3770k on 1200W power supply.... no problem

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.

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!

If you want to crossfire the gpu's then I would not recommend this power supply. If you are only running one gpu then this power supply would definitely suit your needs.

The 600w PSU that you had before was likely defective. Unless you failed to mention an SLI or Crossfire setup with 2 or more VERY high end cards, there is no reason the 600w should not have powered that setup. My 750w is currently powering a 4770k @ 4.6 Ghz and a 780ti that is overclocked.Full Specs:i7 4770k @ 4.6GhzMSI GTX 780ti overclockedMSI Z87 Gaming ITX Motherboard16GB Crucial Ballistix Low Profile RAM2x 500GB Samsung 840 EVO SSDCorsair H100i Water CoolerCorsair Obsidian 250D CaseCorsair CS 750w PSU

This is a really great card. however, your concern is correct. I wouldn't try running it on a power supply that is less then 700w just to be safe. I currently run a 1100w Therm, and have had no problems.

Yes. When you install it, go into corsair link and toggle off multi-rail mode for the ports you plug it into (this is extremely important since the HX1000i uses multi-rail by default and this card will not like that very much). I ran it with an 850W PSU, and while it worked I wouldn't recommend it (at load, the card goes over the 500 TDP rating). 1000W should be more than fine though and the PSU you have has a dedicated 12v rail option. Don't expect to tri-fire/quad-fire with it though.

You aren't going to get twice the power from two cards. You'll get roughly 1.5 times the power, more graphics give diminished returns. It will double the power consumption and heat though.
1056616
yes, you must install a 1500w psu for both graphics card, then youll have a quadfire installation, so it requires more power, greetings and hace a nice day
