What power supply requirements would I be looking at to run a pair of these cards? Assume a standard build with an i5 CPU, Hard Drive, and Optical Drive. No overclocking.

I run two 27" 2560x1440 display port monitors off of one of these cards with no issues. Max power is 19.5 W. It will work in any system. Works perfectly for business applications, and light computer aided design applications.

If you just need to drive two displays for spreadsheets, one of these cards is sufficient. If you need 3-4 displays, then you would need two cards. These are low power draw cards, so even modest power supplies should handle two of them, say a good quality 400-450W or 500 W with a brand X quality power supply.

I have minimal wattage from my power source. the rating is for max need. mine runs my media center without lag i don't know about games but i am very happy with my graphics. i think you have more than enough wattage. and you can't beat the price

Forgot to mention, these cards do not require any extra plug ins from your power supply. That should give you an idea how little the video card needs.

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.

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.

Hey. As per specification each of these beauties has a 250W power consumption.So it recommendable to get a 1200w or more PSU for three of this kind. You'll be more than well served with a 1600w PSU for a 3 WAY SLI.Cheers!.http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-780/specifications

Just looked up the Dell Optiplex 790, which has a number of configurations. Spec sheet is downloadable here: http://www.dell.com/learn/us/en/04/shared-content~data-sheets~en/documents~optiplex-790-customer-brochure.pdf As usual with prebuilt systems, every configuration that I ran through Newegg's power supply calculator was using every watt that its meager power supply put out. Don't add so much as a hard drive without replacing that PSU. The heftiest one your system can come with is 265W, many come with a 240W PSU (depending on if they put one of the 95W CPUs or the 65W in). Anything bronze rated or up at 300W+ should do the trick. The Radeon 6450 only adds about 10W of consumption... but that would push an Optiplex 790 into brownout territory. FYI: voltages in a PC setup are standardized, immaterial to power consumption. The voltages it uses are the voltages supplied by a PCIe slot. This card has no extra power supply input. More info here: http://en.wikipedia.org/wiki/PCI_Express#Power Also, for that ~$40 and 10W you don't get much. I bought one for my parents' home theater PC to stop a microstutter when playing 1080P 60FPS flash video, and I chose this card for its compatibility with their old Llano APU in a dual graphics setup... if you're buying it to play games, you might want to look a little further up the pricing ladder... unless you're just playing games from ~2009 or retro-styled indie stuff. This would be better than an onboard intel GPU, at least in terms of compatibility, but that's about all that can be said for it.

It is recommended that you use a 400 watt power supply by AMD, but in reality all this is for is to save themselves from hearing about defective cards from users that may have cheap or low end power supplies. I have one of these running in my secondary rigs with a 300 watt power supply without any issues what so ever. Though 300 Watts is as low as I would go.

by the specs of the evga card you're looking to run, sure it's an ok psu. the problem with this psu, is that it's not meant to run long hours. so if you're planning to run your system long. them no. also take into consideration how much overall wattage you will need to run you set up. mother board, cpu, video/sounds cards, fans, lights, hard drive. You have to be able to power all these things at once. don't buy just any old power supply.

I'm running one with the same cpu as well, my power meter on the system shows about 620 watts during game play. I do run two hard drives, 1 HDD and another SSD. Other than that there shouldn't be much difference. You really don't want to run a power supply that close to max wattage, I ran a 650 on mine for a while and went out pretty quickly. I would say upgrade the power supply or go for an Nvidia at the same price range. They usually use less power.

Hi, according to the website product info page regarding the Raven RVZ01, it states "Support graphics card up to 13", width restriction - 5.88".As far as the 450 Watt power supply...well not so much. It is recommended to have at least a 550 Watt power supply. Now, if you don't have a power hungry CPU, and you are not overlocking anything, you might be able to run the card with no power issues. FYI, any higher end graphics card like the GTX 770 will need at least a 500 - 550 Watts power supply, to feeding it. Cheers!

I have an Alienware Area 51 ATX Tower with a 1000 Watt Power Supply. I have no problem running this card. I would imagine if you ran two of these in SLI you would probably need a Nuclear Reactor! LOL

Really depends on what you will be running. I'm using a 850 watt Silverstone PSU. I runs all my components well, including my new 770GTX. Plus I may get another 770 later for SLI and it should accommodate that as well. Otherwise a 650 watt or so PSU would normally suffice if you only plan on using one card. This case can handle all of them in any event.

Depending on how many HDD's, optical drives and cpu, a decent quality 350 watt should work fine. We've ran it in two different computers with a 500 watt antec and 550 watt antec with zero issues as far as power, a quad core and two HDD's in one pc. In fact, my system with a GTS250 only pulls 200-210 watts (total, system wide) while gaming and despite being an older video card, it does pulls a lot, so 350 should do the trick if that's all you have at the moment.

Alright i currently have one of these bad boys in my rig im looking to sli i have a amd Black 8core with a sabbertooth fx2.0 and a 850 power supply im looking to grab another one to SLI any idea if im gonna need a bigger power supply ? thanks for your help !!!!

The latest EVGA drivers support 3-way and Quad SLI. As others have already stated, motherboard support is the first hurdle. The second hurdle is that you would need a monster PSU. Each card can draw up to 250 W. Each card also requires 2 x 8-pin PCI-E power connectors.

I would agree with other answers here. In general, power supplies operate at their highest efficiency at 50% load. This is why most enthusiasts would recommend getting more headroom than you really need. So let's say at idle or mild workloads (web surfing, email, etc) with 2 GTX 780 sli I can imagine the system running at about 400W. Therfore 800W would be a good minimum to be working with. However if you plan on overclocking the CPU or GPU's, you'll probably want a little more headroom. I'd recommend 850W unless you wish to get 1000 for future upgrades. Take a look a the EVGA G2 1000W which comes with a 10 year warranty before making a purchase. Highly recommended. I would agree with other answers here.
