The card has been billed as the first mainstream affordable Fermi and it utilizes a traditional block-like cooler unlike older NVIDIA cards, with its fan located dead centre. However, perhaps the most striking thing you'll notice about the GeForce GTX 460 is that it is significantly smaller than previous Fermi cards. The reference GeForce GTX 460 measures only 8.25 inches in length, which makes it easier for it to fit into compact mid-tower casings.
Also, the GeForce GTX 460 requires less power, with NVIDIA stating that its maximum rated TDP is only 160W. This is much lower than any other Fermi card, considering even the GeForce GTX 465's maximum rated TDP is a considerable 200W. The GeForce GTX 460 can therefore get away with a wider range of PSUs, which also means users need not purposely upgrade their PSUs to accommodate the card.
