The 600W unit has a little better result compared to the 500W unit but we still see 4% fluctuation on the 3.3V rail. The 5V rail seems a little better with this unit with a regulation range of around 2%. The 12V rail has a slightly different regulation ranging from 12.34V down to 11.99V.That is of course still within specification.

The ripple looks similar to the 500W unit with the 3.3V rail going up to around 40mV and the 5V rail being able to keep a stable 14-15mV. The 12V rail looks good with only up to 63mV on the 12V1 rail.

Probably because over 90% of the computers that exist are built by OEMs, and a high quality power supply is too expensive for that application. You are going to have a hard time selling consumers on "higher quality power" when that is something they expect to just work.7Enigma - Wednesday, January 20, 2010 - link
A patent on a 140mm fan? Seriously? What a load of crap. They should have made the 139mm 139.9mm and put a big red F in their booklet with the name of the patent-holder. What is this world coming to?7Enigma - Wednesday, January 20, 2010 - link
I have to say I am very pleased with the modular PSU's sticking with the same plug design. That would make cable management after installation a thing of the past which I think for 90% of us DIY builders is what keeps us from replacing a PSU mid-upgrade cycle. Instead just disconnect the cables from the old PSU, pop in the new one, and connect the cables again.I do want to mention a PSU I installed for my cousin about a month ago. I for the life of me can't remember the brand but it was definitely a high-end PSU. It was modular and instead of using the typical A/C plug style to connect the cables to the PSU, it had similar to a microphone plug; 3 pronged in a triangle fashion with a locking collar that you had to screw down. It was a VERY well manufactured piece and there was no issue with feeling the connection wasn't solid.
Anyways glad to see a PSU review again. I got burned a year ago when I jumped the gun on an early recommendation for a PSU you were just starting to test and have been unhappy with its rails and overall quality (Tuniq Potency). Penny-wise, pound-foolish and all. I've been trying to justify upgrading to a better PSU and I think the time has just about come. I just hate the though of doing the cable management again...definitely going to be getting a modular PSU again (previous to the Tuniq I had an Antec NeoPower 480w which was awesome in its day).

the best i can find these for is ~$240 for the 600watt, and ~$275 for the 700watt.so far, i can't find the 500, or any of the "pro" series.
i guess they figure somebody spending that much on a psu is only going for the top.

Yes, unfortunately Enermax USA won't take all of these six units.strikeback03 - Wednesday, January 20, 2010 - link
So does that mean we won't see the 500W units?Well, at least there is still Seasonic.

I heard they will be bringing the Pro87+ 500 & 600W.dukeariochofchaos - Tuesday, January 26, 2010 - link
i have seen these come down in price in akihibara already.in the right places, they are ~$200 for the 600w, and ~$230 for the 700w.
i have also seen the "pro" models around for about $50 less for each.

Pedant ON. Its not a square shape its an octagon, to match the octagonal hole for the fan and (most) of the metalwork forming the fan guard. Pedant OFF.
