Use a PSU calculator. Add about 100watts+ to your total for safe measures.

The GPU you're speaking of, the Radeon 4850 recommends a 450W PSU for a favourite gadget, not in basic terms for the snap shots card. The GPU is rated at 75W, the advice is a regularly occurring regularly occurring for laptop purchasers. This huge kind is organic hypothesis in line with subject-unfastened laptop setups, alongside with a CPU, Motherboard, hard disk, and cooling. Your modern-day CPU, the middle 2 Duo, as you suggested is rated at 65W. A i5 is extra often than not rated at 95W. so which you're looking at increasing your power intake by applying 30W. do not overlook that a power grant will usually in no way produce the Watt score advertized, that's basically it somewhat is max ability. there are countless third occasion labs who attempt the actually output, yet even that could have a comfortable variance. So supply your self a ~15% variance while finding out on a power grant. As to your undertaking, mutually as you're "ok" working it as is, there are disadvantages at overburdening a power grant, alongside with overheating the ability grant inflicting it to grant uneven voltage, or total failure, those can harm your laptop. i could improve it. objective for 500W+, yet no ought to truly go over 650W except you intend on including a 2d video card, or upgrading. a number of the extra recent video enjoying cards, like nVidia's GTX580 can take upto 277W by applying it somewhat is self.

CPU power consumption charts

As far as mobos go, it depends on the mobo, but the average is around 100 watts without a GPU attached, and for every graphics card attached, add 75 watts to the boards consumption. Ram power consumption is factored in the with board, because its near zero. Most 4GB DIMMs will use something like 3 watts.
