Buyer beware on these.
The Seasonic version of this power supply was excellent. All of the ones you'd find at retail today are 500D models from Delta, which have not been thoroughly reviewed by anyone. Cursory teardowns have shown the components to be lower quality than the older EA500s though.
The Delta Earthwatts 650 is very good. The 750 seems to have some weirdness going on 12V rails in terms of ripple.This sounds like my initial impression from 2 years ago. I own all Seasonic Earthwatts, but from what I've read (like at Jonnyguru), the Delta Earthwatts are actually a cut above.

In nearly every way I can think of, this new Delta platform is a worthy and improved successor to the older Earthwatts designs. It's better designed, regulates better, and is more efficient in general than the EA500 we last tested in January of 2007.
It's not bullshit.
Please refer to this thread where they discuss the differences: http://www.jonnyguru.com/forums/showthread.php?t=4067
The EA650 whose review you quoted is a fantastic product and should be considered by anyone considering a non-modular PSU of that capacity. The EA500 tested in Sept. 2007 was an original Seasonic built unit. Please do not put the EA500D in the same category as the EA650...they are built on completely different platforms.
None of the major review sites have tested an EA500D because Antec gains nothing by sending them units for review. The original EA500 was a gem, and they want you to believe the EA500D is also. Honestly, I'm sure the EA500D is a functional unit, it just isn't exceptional like the TruePower New or EA650. I personally would rather hunt and peck for sales on Corsair's VX450 or Seasonic's SS500-ET. The Antec Neo ECO 520W is also an option at ~$60.
