Dell PSUs are underrated, and 120W is enough for an 8400GS, which has a TDP of only 40W. Plus, the PCI rev. 2.3 or something has a section that states that the maximum power draw of a PCI card cannot be more than 25W from each power rail on a PSU. Additionally, only 6W or so can be drawn from the +12V rail, leaving more than enough useable power for the CPU. But still, getting a new 250-300W PSU (from any brand, that system is not going to stress it much) is recommended to leave some headroom. Just make sure it fits in the case properly.FusilliJerry82 said:Do you have any idea how weak 120W is? The standard minimum nowadays is 300W.
However, running it on a 90W PSU is not something I can believe either.
