Modular PSU are godsends if you're building your own computer. Also Corsair and Seasonic are two of the most highly rated PSU on the market at the moment. There are other companies that make great products at a lower price, but no matter what corsair/seasonic you buy, you'll get at least a good power supply (some of those other companies also have cheap products that are complete garbage).
