I'm adding this, a MSI NVIDIA GeForce GT 640 2GB, and 6GB of RAM (for a total of 10GB of RAM.) to my Inspiron 580. What power supply should I get?

A 500 Watt power supply would be fine for you. Your CPU takes 125W and the 640 has low power requirements, 75W I believe, so a 500W PSU is pretty standard for your build. If you are planning on upgrading in the future you might consider a 600 or 650W to save you the cost of upgrading the PSU when the time comes.

It really depends on your graphics card. I have this, 8GB of RAM, and a Radeon HD7770 with a 550W power supply and it's plenty.

I've got this CPU, Radeon HD 6850, 4 rams (2x4GB, 2x8GB) and 2 hard drive and I have a 500W PSU. I think I'm better upgrade the PSU, but at the moment, I don't have any problems and everything works fine...So I guess a 500W would be fine for you.

It can depend upon a number of things. What takes the most power is truly your Graphics card, followed by your CPU followed by Hard drives, followed by RAM.You can probably get away with a good 550W power supply. I went Corsair Professional Series on my build, and have had 0 problems with power. I'm running a 750W.

very good gpu.. I bought this graphic card too.. and i like it too.. its perfect to me, no need a big power supply.. 450 watts, its ok to work fine, because the graphic card need only 75 watts ;) and with only this 75 watts she makes a very great job.. dont worry.. its a good choice :D

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.

I believe the recommended minimum power supply for two GTX 780 cards is 800W. From personal experience though, it is always better to have a power supply that exceeds the recommended minimum. I think your best bet would be to go with the 1000W.

The box of the graphics card recommends at least 450 Watt power supply with 12V@40Amps, which is higher than a lot of cheap 400 or even 500 Watt power supplies have. Specs on a site like newegg will give you the amperage details that Amazon doesn't list.

The power target of the GTX 660 is only 115W compared to its TDP of 140W (and reviews seem to show it running closer to that 115W). You should be fine adding it to your system, assuming you don't have 10 HDDs in there as well.

According to NVidia, this card pulls 49 watts. It does not have any 6 or 8 pin power connectors. As long as you have at least a 300 watt power supply, it will be fine.

Depends on all the other hardware you may be running. Such as extra CD/DVD drives, multiple hard drives, etc.. But with a stock PC, the standard power supply that came with it will be sufficient. Personally I would prefer to replace it, if your PSU is under 400w and in addition if it is already several years old. A reliable brand replacement of 500w-600w is available for around $50 or less. It does have an install disc, but it is best to get the newest driver directly from nVidia website. http://www.geforce.com/drivers From menu on this page select 'GeForce', select 'GeForce 6 series', select your operating system, 'start search'. Select newest driver on top of the list, download and install. Couldn't be easier. :=)

The power supply must be 350W or greater (with a minimum 12V current rating of 20A). One card which consumes less power is the Evga GeForce GT 430 requiring 300 Watt or greater with a minimum of 22 amps on the +12 volt rail. The lower memory capacity has less heat but less gaming satisfaction, and it's compatible with Windows 7.

Depends on what the total system requirement is. 750W is fine for most requirements, way more than needed for most requirements.

Hi, Daniel: If i understand your question correctly, you are asking about what the power supply better for the GTX650Ti... my suggestion is 600W that i am using right now! hope this helps... Forest

I have a 6950 and a 5850 both running at max in a computer at it the entire system draws 500w at the wall, so a for a single 6950 I would suggest 450-500w of a good quality power supply. (You should only use about 80% of your power supplies rating.)

Check out your spec's at Dell and then compare with NVidia site http://www.geforce.com/hardware/desktop-gpus/geforce-gt-630/specificationsThe main thing is to be sure you computers Power supply is sufficient. This card requires a minimum of 300 Watts.

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!

MSI recommends a 350w or greater power supply. Having said that, other reviewers here say they're working fine with as little as a 250w supply. It will all depend on what else is going on with your particular PC. Start adding other things like extra CD or disk drives, extra PC or PCIE cards for other purposes, and you'll have issues. This card is good to upgrade PCs that otherwise cannot be upgraded, especially slimline machines.

Joshua, My best advice is to contact EVGA with your make, model, of computer so that they can best advise. This Power supply comes with all sorts of cables but I rather be sure than disappointed.

I am not sure about the power supply/ computer you have. I have used this card in two different hp computer with the standard power supply with no problems. It'sa great card to replace standard graphics on the mobo. I would consider a more expensive card if you are a gamer.
