I just recieved my 600w psu. All of the rails are solid, no variance at all.

For anyone looking for an alternative to ewiz, I ordered an S12-500 from buy.com a few weeks ago. The price is $120, free shipping, plus if you sign up for the buy.com credit card, you get $30 off, so I got mine for $89.99 shipped.
Yes, of course you have to sign up for a new credit card, but I haven't done so in many years, and I have really good credit, so I didn't mind too much. Obviously, you're feeling may differ.

The S12 has not been known for its solid rails, just to let you know.

I'd like some of what your smokin. The S12 has some of the most stable rails I've seen, especially for a PSU with 80% efficiency. Where do you guys come up with this stuff?

I guess I got a good one? voltages are 3.33v/5.01v/12.04v
and do not change at all according to mbm and everest. My neopower 480w varied a little though.![]()

Well I'll look for some back up, but it has been said by many that if you want solid OC rails you should look to the Powerstream.

The new Enermax Noisetaker V2.0 is very efficient and stable. I've tested the 495 V2.0 against the S12/500. The Enermax is more stable and a lot cheaper.

Tested with a calibrated Fluke true RMS multimeter. The Enermax sample is has a deviation of less than 0.1V at the 12V rail. The Seasonic is a tad bit higher than 0.2V.
Even if the average person was to use the reported voltage in windows, the actual DELTA would be the same, since we are only dealing with line voltage fluctuation, and not ABSOLUTE value.
As for power efficiency, the Seasonic has a 2 to 3% edge in efficiency at the very low end of the output (less than 100 watts). They are about the same between 150 and 250 watts. I do not have the capability to test at higher output due the components inside my PC. I connected the Fluke in series to the AC line to measure the actual AC current. Another calibrated meter was used to measure line voltage.
The efficiency is between 76% and 79% for both PSUs up to the test limit of 250 watts.
The Enermax has much better airflow at low speed due to the dual push/pull fan configuration. All I hear is a small whisper of airflow at the 80 mm fan at low to medium load. Both PSUs were quiet at low to moderate load. The BK SPL meter indicated a 1 to 1.5 dB advantage with the Seasonic PSU. Such an improvement would be inaudible in any PC case.
The Enermax has a huge lead in cabling. The main power wire in the Seasonic is NOT covered by a wire loom. Plus the Seasonic cables are not very long.
No one has come up with any proof that Seasonics are more reliable than Enermaxes. Finally, for the price comparison, the basic EMX-EG495P-VE SFMA cost under $75. That's almost 50% off the price of the S12-500. There is no advantage in spending the extra $ on the Enermax AX with auto line voltage selection.
I see NO justification for the price premium placed on Seasonics PSUs. If you require a dual fan PSU, then go with the Enermax. If you favor a single 120mm case fan, then buy a Fortron. If you believe in the Seasonic hype, then buy a Seasonic. True, Seasonic PSUs have a TINY advantage in efficiency and noise output, but the noise is not going to matter in real-world application. Does a 3% edge in low power efficiency warrant the 65% price premium? Not for me!!! And don't forget the short, uncovered Seasonic power cable.

I hope you don't actually think you're getting a 36A 12v rail from a rosewill psu. You can't directly compare power ratings, because everyone rates their supplies differently. Here's a good thread for some basic power supply info: XS Power Supply Sticky
That said, the rosewill may still give you better bang for your buck, but you can't compare it to a high end seasonic / fortron / antec / enermax / etc.

furballi, your efficiency testing results are not in line with other credible tests. First I'll point out silentpcreview where efficiency dips to 77% at 65watts, and is at 83%-87% from 90w-600w. Second, this power supply is 80 PLus certified, which requires >80% efficiency at 25% load and higher. Their testing methodology seems to me more rigorous than yours.
It would be nice if the cables were a little longer, but they presented no problem for me in my setup. Sure the wire loom is a plus, it's really a minor nit. It costs pennies for the manufacturer, and if it's important to you, you can spend a buck or two and put it on. The Seasonic comes with the Dr Cable kit, which is I guess where they put the few cents budget of cable management into.
I think the "auto line voltage selection" aka Active PFC is more signficant than you imply in your mention. In a nutshell it more efficienly pulls power from the wall. Here is seasonic's explanation of it: here. Although for residential customers in the US, it doesn not reduce utility bills as they say. Aside from the environmental benefits, if you care, the other benefit that if you use a UPS, it doesn't have to work as hard and you can use a smaller UPS or get longer runtime.
Anyways, I can't dispute that the Seasonic may not be the best value for everyone - perhaps that Rosewill would fit that bill. The seasonic though, is likely the most efficient and quiet supply you can buy, but that is not necessarily important to everyone. And like most things, the incrmental improvement to be the best at something costs a significant premium. However, unlike some of the "premium" supplies from other companies, you do get something for your money with Seasonic.
You actually tested & measured a PSU @ 600W DC? How exactly were you able to fully load a PSU at 600W when the most power hungry of desktop systems today don't even come close to doing that & what Enermax PSU comes with a 1 year warranty? "3 Years Warranty" is clearly stated on the side of my Enermax PSU's retail packaging.Originally posted by: clarkkent333

Well said. Plus you can't put a premium on the Seasonic sound quality. Even at 600w its almost inaudible while my Enermax was definately audible. Not to mention the warranties: Seasonic - 3 years
Enermax - 1 year
