Efficiency: Overall efficiency must be 70% min. measured at normal AC mains voltage and frequency with maximum loads on all outputs.
This is horrible. Lets hope it does work a lot better if/when tested.

±1% regulation is impressive. OCZ and PCP&C are the only two manufacturers that I can think of off the top of my head that will guarantee such a low ripple, and their power supplies are surely louder than this.
But other than that, nothing else really catches my eye. 70% minimum efficiency isn't spectacular. And IIRC, the NX-4090 was less efficient, louder, and more expensive than a comparable Seasonic S12. I'd assume the NX-5000 will follow a similar trend.
But maybe I'm being too pessimistic. Will definitely be interested to see SPCR's review of the power supply.

If nexus was smart they would just rebadge Seasonic S12s and perhaps use a nexus fan in place of the ADDA.

Seasonic fanboy.
There's plenty of ways nexus could innovate to compete well with seasonic. They could make the fan grill removeable without voiding the waranty. They could create some kind of mechanism for the fan to slide out to improve airflow, maybe even to do so at an angle(so it would sort of rotate out), so that the air has to turn less than 90 degrees. They could include a duct that attaches to the bottom of the PSU(and mounting points), for it to either take air from the CPU heatsink, or to avoid doing so. The could add coverable holes on the side(similar to a certain rosewill model), with attachable ducts for use with the P180 and similar cases.
And some people like fortrons.

Fortrons tend to cost less and are more readily available too. However I think Nexus should do more than a couple of changes and a rebadge, there are plenty of changes you could make to a power supply to make it better.

Anyone bought one yet? Reviews? Btw, 'minimum 70% efficiancy' is what Nexus quote for the 4090, but that averaged 77% between 65w and 200w in SPCR's review.

How does this compare to S12 under 150W? S12's are really loud if you put your head inside your computer and listen, so hopefully this provides a cheap alternative that is more silent. I modded a Nexus into a Super Tornado once and got that low-20's dBA down to 17-18dBA. waiting for review.

Was that really a review?
From what I could see, they didn't test anything at all by themselves, only stated the manufacturers specifications and were happy with it. No measure of noise, ripple, efficiency etc.
They said it was silent with 17 dB, but nothing more. I don't even think they measured that by themselves. It's probably Nexus own specification.

So? Fortron makes excellent power supplies, if perhaps not among the quietest. For all those who aren't silence freaks like us, Fortrons are just fine

Yep, but unfortunately we are silence freaks here :/

It appears to be cooled by a high-speed sleeve bearing Yate Loon (D12S
H-12) according to
this image... that does not bode really well for its quiet potential... doesn't the NX-4090 use a medium-speed fan? Sure, the fan controller can keep it at a low speed, but still.
Oh well... we won't know until enough SPCRians buy it or a real review is published.
