SUMMARY
If you buying a new PSU you should get one with a 24 pin main power connector, and its likely that in the not so distant future, you might want one with an 8 pin auxillary +12V mobo connector as well (see the following)

what you dont want is a 20 pin main power connector

well I just read something that might have some bearing on everyones purchasing decisions (thanx sn2op for the linkage ;) )

the boys over at trustedreviews got to go over to Germany and use a Fast Auto FA-828ATE load tester (very similar to what Intel employs in there cert program, but they use Chroma

and well in passing they mentioned....

Other additions to newer PSUs includes a 24-pin EPS style power connector, instead of the 20-in ATX power connector. This has been designed for the new Intel Pentium 4 processors, but has been a server and workstation standard for some time. Added to this is a new eight pin 12V connector, which will eventually replace the four pin 12V connector, but this is unlikely to happen for a few months yet. A six pin connector for PCI Express graphics cards should start appearing shortly as well. Some of the power supplies on test came supplied with this six pin connector as a small converter, which would work with pretty much any power supply.

the part in bold, I rushed right over to formfactor.org but there is no sign of the new spec, but it sounds very plausible to me, basically ATX12V is going to conform to Server System Infrastructure (SSI) EPS12V
so that might bear on everyones upgrade path (unless you have an EPS12V that is :p )
 
Oh but why leave out the other fun "tidbit' that was in that review :D
 
well I left that for the other thread sn2op started :p

many might regret certain purchase decisions (hows that for circumspect :p )
but this one is aimed at making the membership aware of the potential change in the spec
something that I think has a greater bearing on everyone looking at a new supply that is going to last past their current board ;)
 
well there is no constraint on you :p

(or even me if truth be told, however I think this is the bigger issue)
anyone asking about buying an X-connect in here is likely to be lynched, drawn and quartered then burned at the stake already :p

Well I will leave well enough alone since it is already in another thread but maybe in light of this review the self destructing ultra may warrant a sticky since that psu is rather popular?
 
So, uh, any particular reason there won't be an adapter for the 8-pin 12V? Seems like it would be easy enough to rig, so I don't see the limiting factor here.
 
your going to want to pull alot of juice through those wires, so its best to get all 8 to begin with rather than split the four ;)

Its also possible the spec might follow more than just the connectors
in EPS12V there are 3 to 4 +12V rails
 
Every day that passes and every new developement around here, I keep grinning and nodding, happy that I bought an EPS12V supply. Been advocating for them as the future since before we had a PSU forum ;)

hehe well i dont care since my current mobo uses some crazy spec that only a handfull of boards used :p

but its a nice psu (Fortron 550w) so it should last me till this board reaches EOL

???ATXGES???

or some other weird spec
 
Hmm. And I thought the 8pin was only for dual processor mobos. Would dual core cpus need the extra power?

Well, good time to plug the new Seasonic S12 that just came to Newegg. When I was reading about the s12, after all the good words about Seasonic power supplies over at spcr, I was thinking, "Why the hell would I need a 8pin dual cpu plug?" Now you can buy it in the name of future-proofing!
 
Indeed, the last two PSUs i've bought have both been EPS12V, even thought it was just this month that I finally upgraded to a system that utilizes the 8-pin/24-pin combo. All about peace of mind
 
Dammit!

And I just bought a new Enermax NT 701ax, to replace the coolergiant 485ax I also just bought (too loud).

I remember the day good old days, when you could at least count on PSUs not to obsolesce (possibly a made up word) so quick, and now it seems that you have to upgrade them like a graphics card every 15 minutes aswell.

Although, presumably, with Intels new dual-core processors looking to be availiable much sooner than expected (this end of the year, instead of the far end) it makes sense that a multi-processory, servery type power setup is going to be somewhat desirable.

Oh well, the treadmill continues.
 
what the !!!!!!!!! i just got a neopower and a munch in gut after reading this.......damn marketing industry !!!they'll die someday
 
now now now
you wouldnt want be be using ISA slots would you?
progress sometimes hurts

we are talking about where the spec is headed
for components that are on the bleeding edge
or still vaporware

we have a new era of power hungry workstation level components comin down the line
and its not all that suprising they will need workstation level PSUs

considering what 2 x 150 watt PCI-E graphics cards would set you back
another PSU upgrade is a mild penalty
with 15A on the +12V2 in that Neopower your at 180 watts, no where near enough for dual SLi 150 watt vaporware beasts, and possibly stretching it for a single 150 watt PCI-E card w\ the rest of your components on that rail thrown in

It's the life we chose...
 
Thanks for the heads up on this, I changed my purchase from the enermax 535 SLI ready PSU to an Antec truepower550 EPS12v, the 24 pin connector plugged right into the A8N and I have a spare 8 pin 12v connector for the future :) 36a on the 12v line and +/- 3% is pretty sweet. My trusty fluke 79 says the 12 volts fluctates from 12.1v at idle to 12.09v at full load. I can always cut off some molex connectors and replace them with PCI-e ones pretty easily when I want to clean up the clutter. it also has a seperate line for fans with 2 molex connectors with 12v only, and fan monitor line. Bad thing is no split 12v, but with this kind of regulation, I dont' see a problem with that.
 
if the new Intel i955X board is any indication, looks like you were right

...one will note that a PSU upgrade may also be in order . This is because the Intel D955XBK reference motherboard was designed around the Intel ATX12V version 2.01 power requirements. Note the 4x2 12V power connector just above the CPU socket and the 24-pin ATX power header below the memory DIMM's.

Wonder how much PCP&C will charge me to put on of those on my 510W PCI-E? Or should I go all out and get the 850W? :eek:
 
well we have the 150Watts per card of the new PCI-E spec (12.5A +12V)
but here is a taste of dual core amperage
http://www.hardocp.com/article.html?art=NzU2

w\ 130W Thermal Power Design (10.83A)
thats up from the 9.8A of a normal Prescott
not as bad as it could have been, and actually overall you might consume less
but if you are a crafty bugger and manage to peg that CPU (both cores)
the worse case senerio just got worse
 
Looks like my nice new RealPower just become EOL for me... :( It has the 24-pin, but still a single 4-pin ATX.

Isn't it funny how similar server-grade and mainstream are becoming? It started with 7200rpm hard drives, and now it's trickling into PSU connectors.

BTW, ridiculous that the chipset alone has a heatsink to rival the PentiumII and slotted Pentium3!
