I use these in all my non-gaming PC builds now. They're pretty much silent, they're efficient, and have all the connections I need. The modular version is my first choice, but if the budget is tight then this fixed lead model is just as good if a little less tidy.
Five stars because it does what it says in the spec. Cheaper PSUs just aren't worth it - they fail often, and they lack the right power distribution between the power rails, with the 12V not being spec'd high enough for even a moderate graphics card. No such problem with this one however.
If you're building a new PC to a 500W spec, or replacing a failed one, this won't let you down.
