Phantom

Since some of you are interested in this.

Manual links don't work yet, but that should be corrected soon.

Thanks for posting the link!

Does "Dedicated output circuits for each voltage eliminate combined-output limitations" also mean that there are separate pluggable cables as with the NeoPower PSU? The pictures now available at the Antec link do not show the Phantom's cable arrangement.

The main page says: "Ultra-high-efficiency circuitry (at least 85% efficiency) saves energy and reduces heat." The specifications page says:"70%(min.) at full and typical loads, 115V/230Vac 60/50Hz 60% (min) at light load." I'm confused. In my mind "at least" and "min(imum)" have the same meaning.

Am I the only one having trouble picturing how that mounts? It seems like half the fins are useless in a standard setup.

But anyway, thanks for for the link! Hope that link means one is on the way to MikeC as we speak!

Why does a fanless PSU have a 3-pin Fan Sensor

See http://www.antec.com/specs/Phantom350_spe.html in the first table under Special Connectors.
Also:

Efficiency 70%(min.) at full and typical loads, 115V/230Vac 60/50Hz 60% (min) at light load

While on http://www.antec.com/us/productDetails. ... dID=24350# it says:

Ultra-high-efficiency circuitry (at least 85% efficiency) saves energy and reduces heat

Is this some bad cut and paste job that needs correction?

Dedicated outputs are based on the TruePower circuits/design. This has nothing to do with Phantom being modular like Neo.

From my meager understanding the ATX12V2.0 specs are the 60% and 70% numbers. That probably has to be addressed better then it is. AFAIK Phantom is suppossed to deliver 85% efficiency (in the US, is't 82% I believe in Europe because of Active PFC).
I'll double check that info though.

fan sensor is for anything connected to Fan Only connectors (if I recall correctly, I'll double check)

My guess is that the deeper ridged heasink surface is actually the bottom of the PSU (in the normal tower arrangement). That would be similar to the arrangement of the recently reviewed Silverstone fanless PSU. The top plate of the PSU would therefore be next to the circuit board to which the components are attached. There is much less radiated heat on the back of a circuit board so the heatsinking would mostly deal with heat that has made its way through thermal conduction from other areas of the PSU? Or so I visualize it. Could be totally mistaken.

Thank you for the quick response and for being willing to do some extra follow up. We may be picky but we love to reward the manufacturers and vendors with superior products and attitudes.

AntecRep - any chance you can find out when this gets released in the UK? Antec never reply to my emails!

Lot of questions, but maybe one more fits.

Is it possible to turn that light off w/o voiding warranty ? I'm not a teenager anymore, so I could very well do without that.

I'll see what I can find out for Europe. At a guess though Mid to late October.

Ok we changed the spec sheet. Not sure that I like the answer though. 86% efficiency at full load.

No Fan Only, nor fan sensor connectors.

AntecRep - Thank you for your extra and continuing efforts and for the answers to our questions!

What do your technical people say about the Phantom's efficiency at idle and typical loads which the average user will encounter? Other PSU's under test have, I believe, generally had lower efficiencies at those operational levels. If that is an inherent aspect of the present state of the art within manufacturing and financial constraints, then there's no shame for Antec to also publish those efficiency ratings. In any case, it will all come out when the PSU is tested by SPCR and others.

Thanks. I think 86% efficiency is a lot more important than some connectors.

So when will it be in the SPCR lab? Are you going to send a sample to MikeC?

My current machine with a sonata case and the sonatas psu draws 110w-150w AC, and since the efficiency seems to be about 65% at that load level, the DC load seems to be 70w-100w. Now, if i replaced it with a phantom, assuming 85% efficiency, i would draw 85w-120w AC and so my previous psu heat production of 40w-50w would be only 15w-20w. I guess it's relatively easy to keep a max. 20w heat (in my case) producing psu quite cool with a case airflow of sonata that has papst 4412f/2gl @ 5v as the case fan.

Mike will be getting a sample, I just don't know when it's going (or if it's already gone).

I should be picking up five off these off the Australian Importer/Distributer tomorrow, plan to use one in my test system,
