Hello, sorry to ask another question. I have been doing quite alot of research about the card and what PSU it can handle. Some people say that GOOD quality PSU's can handle the card with 460W of power. Now, I have 16amps in +12 Volts V1 and V2, which equal to 36amps in total. I'm not sure if that's how it's added up but it seems right. I have two questions out of this. Could the card work well even if it's a very big risk? The other question is this. I do have 1 PCIe 6 pin connected right now. From what I can see there is another 2 or 3 6 pin connectors, are those the PCIe connectors? If not, then I could use the Molex to 6 pin cable that comes with the 560 but how can I install it? I will post pics of what I mean soon.

Though this cable cannot reach my GFX card, there's another cable by it that's connected which is preventing P2 to reach. http://imageshack.us/photo/my-images/804/20110731162616.jpg/ A Molex (?) cable. Is this the cable where I plug the included cable from the card's box into? Or this one? http://imageshack.us/photo/my-images/42/20110731162717.jpg/ Sorry for not having the pictures appearing on my post but having to link them to show you, they had a red X mark.
Should be fine if it's a good quality 460W. My fiancee runs her i5 system with a 560 Ti on an Antec Basiq 430W and it is fine plenty of power.. Really don't use THAT much.. never seen the PC load over 300Ws from the wall under heavy games
Perfect One other problem is that I'm confused if I have 2 PCIe six pin connectors or just one. If I have to use a Molex to a 6 pin adapter, which Molex do I choose that's attached to my PSU?
It doesn't matter. If you have a 2x 4pin molex to 1x 6pin PCI-E molex then only one of the 4 pin molex needs to be connected to the adapter. The other connector is for if you want to chain more devices.
No that's not how it works you divide the watts for the 12 v rail which in your case is 312 Watts by 12 v equals 26 amps not 36 so you are lacking in the amps on the 12 volt rail for that card as it draws 285 watts at full load.Up to you but I think you are playing Russian roulette.
The card does not under any circumstance draw 285 watts. Maybe the full system draws that much. Here is right from the Guru3D review of 560 Ti: "System Wattage with GPU in FULL Stress = 319W" "Subjective obtained GPU power consumption = ~ 169 Watts" That's with Hilbert test system at that time: Mainboard eVGA X58 Classified Processor Core i7 965 Extreme @ 3750 MHz Graphics Card GeForce GTX 560 Ti 1024MB (reference) Memory 6144 MB (3x 2048 MB) DDR3 Corsair @ 1500 MHz Power Supply Unit 1200 Watt
Thanks for clearing up the connection and Amps. My PSU seems realiable enough to survive the 560, or not since I don't have enough Amps. :/ But I heard that it requires 25amps or so.. My computer doesn't draw much power, since it has 1 fan at the back and 1 for the E8400 processor. 1 hard drive and 2 DVD/RW drives and soundcard of course
If you were at 30A or above on the +12v then I would say you are pretty safe, but 26A, I wouldn't risk it personally. Any particular reason why you need to go for a 560? As I see you already have a GTS 450, and a 560 would more than likely be bottlenecked by your CPU anyway....
My GTS 450 is currently faulty, which is why I'm going to 560. Plus, on Nvidia's website itself, it says the 560 requires 450W. I'm getting the regular version, not the Ti which requires 500w.
25A would translate to 25A * 12V = 300W. In truth even my 1GHz GTX 560 Ti doesn't draw more than 200 watts max, which translates to less than 17A. (of course these are just estimates)
Fair enough that was from another site but the point still stands about 26 amps is not enough for anything except a low power video card in a HTPC.It is still pushing the envelope.
I have a CM extreme 600W, though the max wattage isnt written on the psu but it will give at least 400 watts on two 12V that means 34A on the 12V rail... So i guess m safe with the 560..:thumbup:
I have my GTX 560 Ti running in my 2nd rig atm (because it messes up the mic input on my sound card, waiting to RMA it) with a e8400 at 3.6GHz and it's fine on a 400w corsair psu with 30a 12v. Ran a GTX 275 in there for awhile and that uses more power but i sold it because i didn't need a card that fast in my 2nd rig.
I don't understand this. I just got done saying that the GPU consumes like ~170W of power. How is 300W+ of power on 12V rail not enough? Remember he has a low power CPU and very few other devices. People go out and buy huge and unnecessary power supplies - sure it can't hurt to have more power than you need but it does hurt a little bit to waste money.
It's not all about the watts it is the amps it should have about 30 or more amps on the 12 volt rail to run a modern vid card plus that power supply is an older design but whatever guys by all means do what you like. I wasn't suggesting he go out and buy a million watt supply but one that will run it comfortably something 30 or 35 amps on the 12 volt anything less and you are running a power supply at more than 75-80% and over a period of time will lead to failure with the possibility of taking out something else you don't want to spend money on either. I have a friend who has that same power supply with a low power draw cpu and a 5770 that I tried to get him to upgrade the power supply but won't and is now after running it for a few months is experiencing shutdowns.These are sudden just turns off shutdowns.
Buy this, don't ask why, just get it, its the very best in the world imho (bec.i have it.) BTW you can get one w/ higher wattage even. http://www.anandtech.com/show/2655
Technical Support Zotac say that requires a minimum 450W power supply with 24 amps on the 12V (GTX 560 non-Ti)
I reccomend getting a new power supply. Something like this at minimum, http://www.newegg.com/Product/Product.aspx?Item=N82E16817139028 TX650v2 if you want better quality. Using Molex adapters is hardly recommended.
