Obviously it would be better to get something better than what is stated. It is only a rough guide, as it also depends what other hardware you have in your system. I hope it is of some use to people. The following are the minimum power requirements using a PSU with a single +12V rail. Also these requirements are for a system containing basic components (unless otherwise <img src="/styles/default/xenforo/smilies/default/dull.gif"  class="smilie" loading="lazy" alt=":dull:" title="Dull    :dull:" data-shortname=":dull:" /> noted). The more add in cards and hard drives that a system has, the more amperage draw on the 12v rail.  Nvidia Geforce GTX 295 in Quad SLi - 70A and a 1000W PSU minimumGeforce GTX 295 - 50A and a 700W PSU minimumGeforce GTX 285 - 46A and a 550W PSU minimumGeforce GTX 280 in SLi - 55A and a 800W PSU minimumGeforce GTX 280 - 40A and a 550W PSU minimumGeforce GTX 260 OC in SLi - 50A and a 700W PSU minimumGeforce GTX 260 OC - 40A and a 550W PSU minimumGeforce GTX 260 in SLi - 50A and a 700W PSU minimumGeforce GTX 260 - 38A and a 500W PSU minimumGeforce GTX 250 - 32A and a 500W PSU minimumGeforce 9800 GX2 - 35A and a 550W PSU minimumGeforce 9800 GTX+ - 32A and a 500W PSU minimumGeforce 9800 GTX - 25-30A and a 450W PSU minimumGeforce 9600 GT - 26A and a 450W PSU minimumGeforce 9600 GSO - 26A and a 450W PSU minimumGeforce 8800 Ultra - 35A and a 500W PSU minimumGeforce 8800 GTX – 30A and a 450W PSU minimumGeforce 8800 GTS 512MB - 28A and a 500W PSU minimumGeforce 8800 GTS 320/640MB – 26A and a 400W PSU minimumGeforce 8800 GT in SLi - 36A and a 500W PSU minimumGeforce 8800 GT - 26A and a 450W PSU minimumGeforce 8600 GT/GTS - 24A and a 350W PSU minimumGeforce 8500 GT - 22A and a 350W PSU minimumGeforce 7950 GX2 – 27A and a 400W PSU minimumGeforce 7950 GT – 22A and a 350W PSU minimumGeforce 7900 GTX – 22-26A and a 350-400W PSU minimumGeforce 7900 GTO – 22-26A and a 350-400W PSU minimumGeforce 7900 GT – 22-26A and a 350-400W PSU minimumGeforce 7900 GS – 22-23A and a 350W PSU minimumGeforce 7800 All - 26A and a 400W PSU minimumGeforce 7800 GS AGP - 20A and a 400W PSU minimumGeforce 7600 GT – 22-26A and a 350W PSU minimumGeforce 7600 GS – 15-17A and a 350W PSU minimumGeforce 7300 GT – 15A and a 300W PSU minimumGeforce 7300 GS – 15A and a 300W PSU minimum ATI Radeon 4890 - 32A and a 550W PSU minimumRadeon 4870 X2 CrossfireX - 1000W PSU minimumRadeon 4870 X2 - 600W PSU minimumRadeon 4870 - 32A and a 500W PSU minimumRadeon 4850 - 30A and a 450W PSU minimumRadeon 4830 - 26A and a 400W PSU minimumRadeon 4770 Crossfire - 34A and a 750W PSU minimumRadeon 4770 - 26A and a 400-500W PSU minimumRadeon 4670 - 26A and a 400W PSU minimumRadeon 4650 - 24A and a 350-400W PSU minimumRadeon 4550 - 20A and a 300W PSU minimumRadeon X3870 X2 - 30A and a 550W PSU minimumRadeon X38xx series - 28A and a 450W PSU minimumRadeon X2900 XT Crossfire - 45A and a 800W PSU is recommended for high-end rigsRadeon X2900 XT - 35A and a 500W PSU is recommended for high-end rigsRadeon X2900 Pro - 35A and a 500W PSU minimumRadeon X2600 XT - 25A and a 400W PSU minimumRadeon X2400 XT - 20A and a 350-400W PSU minimumRadeon X1950 XTX – 20A and a 420W PSU minimumRadeon X1950 Pro – 20A and a 420W PSU minimumRadeon X1900 XTX – 25A and a 520W PSU minimumRadeon X1900 XT – 22-25A and a 520W PSU minimumRadeon X1900 GT – 22A and a 400W PSU minimumRadeon X1650 Pro – 18A and a 350W PSU minimum  GPU Power Consumption*<img src="/styles/default/xenforo/smilies/default/yes.gif"  class="smilie" loading="lazy" alt=":yes:" title="Yes    :yes:" data-shortname=":yes:" /> Manufacturer Idle LoadNVIDIA GeForce 9600 GT 49W 107WNVIDIA GeForce 8800 GT 64W 115WNVIDIA GeForce 9800 GTX 79W 116WNVIDIA GeForce 9800 GX2 90W 179WNVIDIA GeForce 8800 Ultra 100W 186WATI Radeon HD 3650 17W 32WATI Radeon HD 3850 53W 82WATI Radeon HD 3870 62W 92WATI Radeon HD 2900 XT 67W 104WATI Radeon HD 3870X2 55W 130W* Actual power consumption for the graphics cards only.
