Connector Requirements For PCI Express Graphics Cards
The following tables show the number of the necessary connectors for the graphics card power supply. Exceptions are possible, but in general, the larger graphics cards hold to a reference design. SLI and CrossFire double the port requirements, since obviously you are using several graphics cards.
This article was due. No more you need an 800 watt psu for the 4870 , core2 quad ad 1 hard drive anymore :p
Guest11since Core i7 920 has TDP = 130W, how can it consume 85W only?The TDP is more of a design thing. Almost all of Intels initial Core2 line had a TDP of 65 watts yet many took much less power. Intel gives a worst case of that type number and does not measure every cpu.
AMD does the same thing. They listed almost all the initial Athlon 64's at 89 watts yet many did not take that or give off that amount.
zxv9511.21 Jigawatts !!!You act like you would need a small fusion reactor or maybe a bolt of lightning to get that?
So my system actually has a too big power supply to be effective?
I'm running a 3,4ghz c2d with 5x500gb sata drives, a dvdrw and a 4870 on a p35 board.
According to the article that's not going to draw the ~400W needed to get within effective range of my corsair 620 ....
The TDP (thermal design power) is meant to be a guideline for the cooling solution, not the power consumption. To qualify for a cpu with a TDP of 120W, a cooler must be able to dissipate 120W. Practically, of course, this means it is an upper bound to (sensible) power consumption.
also small note: Is it just me or is it strange to see the 260 SLI consume more than the 280 SLI. maybe in need of a beefier test scene...
