How much amperage do the 7800GTX and 7800GT need ?
Well occording to this review the seasonic S12 600 watt power supply had no
troubles powering a double 7800 gtx graphics card sli setup. http://pureoverclock.com/review.php?id=15&page=1 Small wie So at least the amperage stuff shouldn't be of any concern anymore woeh. Bye, Skybuck. "Skybuck Flying" wrote in message news:... Hello, On this power supply calculator it says: http://extreme.outervision.com/index.jsp The 7800GTX needs about 118 watts of power. The 7800GT needs about 97 watts of power. Somewhere else I also read Current = Watts / Voltage. Since these cards are supposed to be powered by a single 12v+ rail/connector (?) this would mean the amperage is about: 118 / 12 = 9.8 amperage. 97 / 12 = 8.0 amperage. So a power supply delivering 18A on each 12v+ rail should be enough ??? However I have seen many threads say at least 18A or even 24A... So I am a bit confused... How much amperage/ampere do these cards really need ?? Bye, Skybuck. |
