GTX 480 supposedly needs 600W power supply

With a single 12V 42 amp rail


According to
several reports from Cebit, Nvidia's GTX 480 will require quite a bit of juice, as it apparently needs a 600W PSU to get up and running.

While this doesn't sound like the end of the world, it's worth noting that we're speaking about a single rail 600W PSU, with a 42 amp 12V rail to be percise. This could spell more trouble for the green team, as AMD's 5870 feels quite comfortable with just 600W. What's more, AMD's dual GPU 5970 requires 650W, just 50W more than Nvidia's single GPU GTX 480. Obviously, the TDP will also end up rather high as well and some punters are expecting it to end up over 250W.

By comparison, AMD's dual-GPU 5970 is rated at 294W TDP, while the 5870 and 5850 churn out 188W and 170W respectively. With this in mind it's hard to see how Nvidia will be able to deliver a dual-GPU card clocked anywhere near the GTX 480. AMD used downclocked RV870 cores for its 5970, but this approach might not work as well for Nvidia due to higher power consumption and TDPs.
