What PSU to select

In case you didn't notice often on this forum and others, having a decent and stable PSU is critical to a good working PC. The PSU is so taken for granted that anyone building thinking only GPU and CPU concerns quickly finds out the hard way, the PSU just isn't capable even if it works may not for long.
Excluding my basic advise and just get a decent brand name and have at least 100W above your needs will do. The more watts, the better IMHO. But how can you tell what your needs are? Simple use a PSU calculator. Google for hits, but below are some links:
Extreme is a pgm. you can d/l for free version. Also, notice the "rail voltage" specs, these provide the "amps" that overall are part of the final picture. Understand, better PSUs cost more to include better components, wiring and cooling aspects. Alas, your PC should be well cooled as well to help exhaust heat build-up besides what the PSU itself can do, HEAT is a killer.
