Cards up to 75W can draw their power entirely from the PCIE slot. Cards requiring over 75W, need to draw additional power via power connectors from the PSU.
----------------------------------------PCIE slot supplies up to 75W Each 6pin power connector can supply up to an additional 75W Each 8pin power connector can supply up to an additional 150W Power connector requirements for GPU's up to (W): 75W - No power connectors required (powered from PCIE slot). 75W to 150W - One 6pin power connector required. 150W to 225W - Two 6pin power connectors required. 225W to 300W - One 6pin power connector + one 8pin Power connector required. 300W to 375W - Two 8pin Power connectors required. List of some common ATI/AMD GPU's and NVidia GPU's, against Power requirements (TDP): AMD HD 7970 - 230W HD 7950 - 180W HD 7870 - 175W HD 7850 - 130W HD 7770 - 80W HD 7750 - 55W HD 7670 - 66W HD 7570 - 44W/60W (two types) HD 6990 - 375W HD 6970 - 250W HD 6950 - 200W HD 6870 - 151W HD 6850 - 127W HD 6790 - 150W HD 6770 - 108W HD 6750 - 86W HD 6670 - 66W HD 6570 - 44/60W (two types) HD 5970 - 294W HD 5870 - 188W HD 5850 - 151W HD 5830 - 175W HD 5770 - 108W HD 5750 - 86W HD 5670 - 64W HD 5550/5570 - 39W NVidia GeForce GTX 590 - 365W GeForce GTX 580 - 244W GeForce GTX 570 - 219W GTX 560 Ti (448) - 210W GeForce GTX560Ti - 170W GeForce GTX 560 - 150W GeForce GTX 550 Ti - 116W GeForce GT 545 - 70/105W (DDR3/GDDR5) GeForce GT 530 - 50W GeForce GTX 480 - 250W GeForce GTX 470 - 215W GeForce GTX 465 - 200W GeForce GTX 460 - 150/160W (768/1024MB) GeForce GTS 450 - 106 GeForce GT 440 - 65W GeForce GT 430 - 49W GeForce GT 340 - 69W GeForce GT 320 - 43W GeForce GTX 295 - 289W GeForce GTX 285 - 204W GeForce GTX 280 - 236W GeForce GTX 275 - 219W GeForce GTX 260 - 171W (216/55nm) GeForce GTX 260 - 182W (216&192/65nm) GeForce GT 240 - 69W Listed by name (not performance), doesn't include OEM cards. Not all cards necessarily work here. These figures are Reference values (AMD/NVidia). Note that manufacturer/partner variations exist (MSI, EVGA, ASUS, Gainward, GIGABYTE, Zotac, Palit, PNY, Galaxy, Sparkle, Inno3D...). While typical power usage when crunching is ~75% TDP, this can vary substantially depending on the application. [Edit 1 times, last edit by skgiven at Mar 17, 2012 5:21:14 PM] |

skgiven,
For my GTX 560 Ti (448) these numbers seem to be right on the money. I have seen as much as 205W usage while playing games. On a good note , these Beta GPU jobs only used a peak of 130W  Half the time they only drew about 65W and when the GPU was at peak usage it went to 130W. Much better than I had expected. I just hope that will continue when they go into full production. |

Spotted, was a typo - it's actually a GeForce GTS 450
There is a GeForce GTX 550 Ti, but no GTX 450! Thanks, |
