My Antec Earthwatts 650w PSU ided on me, so I too have been in the market for a new one. One good thing about Antec is their customer service, so after a bit of haggling, they are sending me a brand new one.
Now, for a number of reasons I am no longer happy with my Antec EA-650w, so I too have been in the market for a new PSU.
The seasonic gold series seems great, but I am going with the Corsair HX-850W instead.
