Power Supply Recommendation

the Corsair 850tx is a +1. Go for it its a single rail which is good in most psu's.

As you look into the 1100w + then look at split 12v rails.

^^Cant go wrong

If no means to CF or anything, the Corsair 750 could pull that off easily

The number of rails does not matter for a good quality PSU.

I was possibly thinking of a tri-crossfire with the 4870x2 and a 4870 in the future, think it would power that? I forgot to bring that up.

For that I would say HX1000.

A high amperage, 850 or 1000 for that

Actually the rails do matter.. if its a high wattage and the amperage says 25a 25a 25a 25a. Doesn't mean its getting 100a altogether. 25a - 25a will be 25a on one rail and probably 18a on the other.

Since its high wattage, most the amperage is there but, it commercials 22a -22a 20a 25a yada yada, not all rails will run those amps.

The number of rails does not matter on any modern good quality PSU. If you need 100A then you should be buying a higher wattage PSU which has well over 100A available. Switching to a single rail does not mean there are more amps available, just that they are on a single rail.

Which can cause a outrage on higher wattage psu's thats why most psu's 1000w+ are split. Single rail can send as many amperes it wants to into a component, which could overload. When it's split, its limited its components so that does not happen on a high wattage.

How would only sending 20A through a component be better than 100A? It wouldn't make any difference.

"OverLoad"

= electricity pains.

you wont get the full 100a anyways on split rails is what im trying to get at. It's like every one is adding 25a x4 12vrails = 100a. No, it doesn't work like that. Only partial will get the full amperes and the others will be limited. You wont get a graphics card to hit over 20a anyways so split rails on higher wattage is a better deal. "Unless" you have 5 to 6 rails, every rail will not be an equal amount of amperes, mabye some, "mabye" some 4 12v rails on a higher wattage.

Can you guys stop arguing about this. I bought the TX850 power supply.

Relax and enjoy your new PSU.  

That's what over-voltage protection and over-current protection is for, not split rails.

You just go with what you know and ill stick with what i know. Have a good day.

I agree with Fullmetall.

I know that split rails were introduced as a safety measure for the PSU, not the components. A 20A rail is perfectly capable of frying a CPU, RAM or mobo as well as most video cards; many high wattage PSUs have rails with 25A+.

And a good day to you as well.
