I've heard that it's a brilliant PSU in all areas, almost silent, really stable, reliable, etc. It probably is worth the money.
That said, I really like my Hiper Type-R 580 watt. It's really good value, has modular cables and sounds pretty damn quiet to me. It's been rock solid for me in terms of stability since I got it. It gets a fair bit of abuse on these forums though, I must say I can't see why.
The Tagan 580W Easycon Modular and Enermax Liberty 620W Modular some other good options for good quiet PSUs, plus the Tagan is a bit cheaper than the others.
