This is what Mathieu from Hardware Revolution has to say about this bundle from Tigerdirect:
It's unreliable meaning that it can cause BSODs, crashes, freezing, random reboots, is incapable of delivering its rated power, has only 32A on the +12V line (the most used voltage line on a modern PC, so your "600W" PSU can't deliver 400W on what is mostly used) and worse of all, is likely to die after a few weeks/months and kill components in your PC because it doesn't feature overcurrent protection and other safety measures meant to protect your delicate PC components.
THAT is why it's junk.
