PCP&C 850ETX Update

[Ice Czar]

NEW UPDATE & BUMP

the VP of Sales at PCP&C dropped me a PM boys and girls, with an "official" update

The final end user pricing has been established for the 850ETX and is a bit higher than we first anticipated. However, this is the most advanced power supply available in the market and represents the first general purpose PC power supply that is 80% power efficient with Power Factor Correction, full range voltage auto select, compatible with a number of standard ATX cases and still use a standard 10Amp house circuit thanks to high efficiency!

since this is treading the fine line between news and advertising
I'll paraphrase the rest
Its first come first served, starting today, there are a limited number of them
they run $469, no idea about shipping
and you need to call the toll free number between 7:00am
to 4:30pm Pacific Time, Monday to Friday

while these do seem overkill right now
I was justing running the +12V amp requirements on a dually board with the proposed PCI-E 150W SLi figures, (25A 300Watts right there)
and you know what there really wasnt alot of room left over for extra drives ect

and of course for all the Data Storage Fanatics
you now have a solution that will further your plans to brownout the local grid when you spin up those arrays

culled from ....errr elsewhere


paraphrased from a PCP&C email


salient points.
OEMs are sucking them all up and end user availability is forecast for 4-6 weeks from now

its will set you back $429

They recommend cases be 20" deep or greater
EATX being an extended ATX form factor (5.9" x 3.4" x 9.0" deep)

Its a true split plane EPS12V supply with 4 x +12V rails and is really designed for
Dual processor and Dual video systems (with room to spare for RAID arrays)
60 Amps between the 4 +12V rails


Tip your UPS driver it weighs in at a hefty 8 lbs.

This is going into my Lian Li V2000 one way or the other.

 

[Vapor1000]

hmmmm My PC75 should like this nicely...
550enermax EPS + 400 zalman

i think it may be time to switch one of those 2 out with this bad boy...

 

[Ice Czar]

now available bump

 

[mohammedtaha]

So what you're saying is that this PSU will not fit in an ATX case ? I have a Wavemaster ... I believe it's a little under 16"

 

[jetjaguar]

will this fit in an lian li pcv2000b ???

will this fit in an lian li pcv2000b ???

You will have to modify it slightly

 

[jetjaguar]

as in take out the hd holders and the metal divider ?

$470, ouch. You could get two 510W TurboCools for that much.

I wish they would do something about cooling instead of just putting a single, very loud 80mm fan in everything. I mean, how hard is it just put a 120mm on the bottom like everyone else?

 

[Ice Czar]

well the thermal design doesnt work that way
but a second fan is a common mod

I could probably disconnect mine anyway since it being force fed from a 120

I know they'd have to reorganize the inside, but doesn't seem like it would be that hard.
Just gripes me, because it's the perfect PSU, except for the noise / poor cooling issue.

That's how mine will be set up - force fed from a 120mm, but I'm probably not going to have a second 80mm on the back, just the 120mm feeding cold air into the back, and a Panaflo M1A in place of the stock fan.
Did you replace the stock fan? What did you use?

Also, here is a listing for the 850W

[s10010001]

they failed to mention you can recharge your Electric or Hybrid cars with it too.....

 

[Ice Czar]

nope the old fan is still attached but its in a 4U rackmount, w\ 3 120MM fans in the typical midcase postition, I simply isolated the mobo compartment so in effect there is a duct from the 120 to the supply

the thing is they dont have a cooling problem
they do however understand that for every 10C you drop you extend the lifespan 100%
(a rough rule of thumb, based on the arrhenius equation)
http://en.wikipedia.org/wiki/Arrhenius_equation

not to mention capacity


http://www.relexsoftware.com/resources/art/art_prediction2.asp

Different reliability prediction models have different ways of accounting for manufacturer data. If you have concluded that it is appropriate to use manufacturer data in your prediction, there are several ways to incorporate the information.

Use the manufacturer's activation energy value in the Arrhenius equation to determine the failure rate.
If the data appears to have been gathered in such a way that the conditions are similar but the operating temperature is different, use the manufacturer's activation energy value in the Arrhenius equation to determine the failure rate. Replace your predicted failure rate with this calculated failure rate. For additional information about the Arrhenius equation, refer to the Relex help or consult reliability textbooks such as Practical Reliability Engineering (Patrick O'Connor) or Reliability: A Practitioner's Guide (Intellect and Relex Software Corporation).

TIME-TEMPERATURE RELATIONSHIP
(ARRHENIUS EQUATION)

For many physical and chemical processes that lead to
failure due to accelerated temperatures stressing, the
acceleration factor is described by the following equation.
The acceleration factor is a constant used in the reliability
prediction process to express the enhanced effect of
temperature on a device’s failure rate. It is often used to
show the difference or acceleration effect between a failure
rate at two temperatures, i.e. the failure rate of a device
operating at 125°C is likely to be 5x greater that at 25°C.

Each 10°C (18°F) temperature rise reduces component life by 50%
Conversely, each 10°C (18°F) temperature reduction increases component life by 100%.
