Efficiency meets 80 PLUS specifications:
Efficiency under different load profiles:
The Enermax Modu 87+ runs through our tests almost without a hitch. Not only does it offer respectable manufacturing quality, but also convinces with its electrical quality. In the 80 PLUS Gold measurements it barely misses the 87% efficiency mark at 100% load, but not by more than our measurement margin of error. It was very convincing in all the other measurements, particularly by not losing as much efficiency at low loads as its competitors.
There is also a slip up with the ripple measurements. Instead of the maximum allowed 50 mV, the Modu 87+ misses this ATX specification limit with 52 mV on the 3.3 V rail. The 74 mV and 20 mV results on the 12 V and 5 V rails are exemplary, though.
Overall, the Enermax Modu 87+ is a powerful and solid PSU which meets the demands of a gaming environment. Features like running the fans for a minute after system shuts down set it apart from its competitors, and the five-year warranty is confidence-inspiring.

The article doesn't appear to measure noise from during switching and how much noise is introduced to the CPU and bus.
Anyway, it will be a cold day in hell before anyone gets me to switch out my Silverstone 1500 Watt PSU.
You are either lying or very unlucky (got a bad PSU)......I have crossfire 5870s and an i7 965 and all stock cannot exceed 650W at the wall (about 550W actually used) no matter what I try.
I call BS. I could run your setup with my PC power & cooling 750w unit.

My next build will be in an NZXT full tower, and I am particularly interested in the Antec 850W, which I believe is the same line as the 750 tested. The report mentioned something about the cables being a bit short for full towers, I'd like to know exact cable lengths, and does anyone know if the 850W model cables may be a little longer?
You're kidding right? You mention the NZXT power supply as "being one of the best", but no mention or recommendation for the Seasonic (even tough according to your own tests the Seasonic handily beats the NZXT)?
Seasonic is one of the, if not thee, best power supply houses in the land. Most of the times if you see a real good power supply from another brand, it turns out it was a Seasonic unit. I'm not saying there are no other good manufacturers out there... But, to not even to get a nod or anything in the conclusion??
Review fail.
So, essentially it will pick away at your RAM. No thanks.
"...its single +12 V rail (preferable to all of the units with dinkier +12 V output spread over multiple rails)..."
I call BS. I'd much rather have multiple +12V rails. With OCP set appropriately, there's no issue of power being "trapped" anywhere, yet it will be safer in the event of near short-circuit conditions.
I'll be building either a SB or BD rig for myself in late Spring or early Summer, and I already picked up the 560W model of the Seasonic "X" line for it ($71 for the one HardwareSecrets reviewed).
Remember too, that 80+ tests at the absurdly low ambient temperature of 23C. While I think their tests are still generally valid, and will certainly clear out the liar-labeled units, for a certified unit to fail by a couple percent under real world conditions is not too unusual.
