hello my fellow forum friends. im kind of confused on psu requirements and what to get. i have been reading alot on here about peoples opinions on what psu specs mean, and would like some good solid advice. in my systme in my sig, i have a ultra lsp 750w psu w/ a single 40amp rail. is this good for my systme or am i pushing it, and is this psu of good quality?...next, i am wanting to build another pc with the following specs...intel e5300, 8800gt, 4gigs of ddr2 800 ram, 1x250 hd, 1x1tb hd, 1xdvd burner, a multi card reader, 2x80mm fans and 1x 120mm fan. this wont be for games, but mailnly for movies and general usage, hooked up to a 32in tv. i have most parts but need to decide on a power supply to run it. i would like to keep it under $50 tops. i know its a low budget for a psu, but i dont see this build using too much. any advice would help, and sites like newegg or tigerdirect are a must. thanks again
