The Big Power Supply Guide - Trusted Models
Based on specifications, the recommendations of others, reviews, and pure gut feeling, this list is intended to be a quick and to-the-point guide to the power supplies that are worth buying. This list is intentionally short and minimalistic; the target was to have 2 supplies in any given price range. This is in case one of the supplies listed goes out of production or otherwise becomes scarce. It is our recommendation that you budget at least $50 to purchasing a power supply, preferably with some additional padding.
These supplies, except where noted, are "20+4" pin power supplies; that is, they will work equally well with older 20-pin motherboards and newer 24-pin motherboards.
