12volt rails and its output in ampere

[jaykishankrk]

Guys can somebody tell me what difference it makes to have 2 12v rails on the PSU??

how does it help for a system like mine(Rig in Sig). will i be facing any PSU realted issues later with my setup??

if possible please explain a bit more on PSU output load and stuff like that.

Any help is appreciated, down goes the link to my PSU

thanks in advance

The split 12V rail is yet another bad idea from your friends at Intel (who promulgate the ATX specification) that only got traction because of the abysmally low level of technical literacy of the general consuming public (and the american consumer in particular). The PSU makers went with it because that's what those dummies now think they want and it doesn't hurt that they could make a little more $$$ on them (many who had perfectly fine single-rail PSUs either closeted or sold them and bought split-rail units) :roll: . You can still get excellent single rail PSUs if you look around. Silverstone's new 650W unit has 54 Amps available from a single +12V rail. Zippy still has many single-rail models, etc.
. The only real differences are: 1- It is safer to limit the current on a single 12V rail to 20A or less (more than that can be deadly in certain circumstances - but every car has multiples of 20Amps available, so what the hey... ) and, 2- You may not be able to utilize the full 12V power available from a split rail unit without having custom adapters made as each rail has only a specific set of connector types attached to it from the factory. On most PSUs, all the +12V power actually comes from a single winding on the transformer anyway whether it is single or split rail (or even triple or quad rail).

Zepper......more and more ps manufacturers are actually putting out power supplies that are indeed single rail ps's split into several "virtual" rails. Take the Corsair twins. Both, while saying they are triple rails, are actually single rail power supplies. Testing has shown that there is no overcurrent protection on any of the "rails" and putting 30A on anyof the +12V rails will not trip or overcurrent the power supply.

Since Seasonic, one can almost make the leap that many of Seasonic's line is more of the"virtual" split rail design than actual split rail design. After reading a lot on Jonny Guru's website and XBit website, along with Hardware Secret's website, there seem to be fewer and fewer true split rail power supplies and more and more designed as single rails split into "virtual" multiple rails. This trend seems to have come around in response to the increasing current demands the newer gpu's need.

Note: Antec SP, TP & TPII units are highly suspect and will cause issues before the three year warrenty is up. Google Fuhjyyu Capacitors and read. Urban Dictionary defines Fuhjyyu as Chinese feces.

well then i think i need to invest once again on my PSU. can u people suggest me Good PSU in Antec itself because nothing else is available. i am planning to go SLI once 8600 ULTRA is released

I own one.

I wonder about those. I remember reading at jonnnyguru.com in some random review that such-and-such brand of capacitors means don't let your PSU get too hot or they'll fail. I've had three of the original TP and they are still in operation to this day. Not one of them is less than 3 years old. I also have the TP-II 480W and it is over a year old. My thought is that perhaps some systems are running hot, thus causing failures? The thing is that out of all my Antec PSUs, not one of them seemed to spin up the fan/s any faster no matter how hot the PSU got. My TP-II in that little SLI rig I linked to above runs burning hot - seems hotter than the video cards themselves. That MicroFly case is nice, but there's a lot more air exhaust than vents for intake, so air almost doesn't move through the PSU. The same PSU ran much, much cooler in my CompuCase that had great ventilation.

For a PSU from Antec, I would say EarthWatts if it's available. It's a Seasonic-made unit but with none of the sleeving that most Seasonic PSUs have (such as the Corsairs).

can u be more precise on the model of the PSU please. i have an option of buying an earthwatt here in my country so it would be great if you suggest me the model directly keeping in mind my SLI requirement
