some people claim pc power & cooling single rail design is better then multi rail - is this true? :?:

i thought each rail was limited to 18 amp and 20 amp max by some safety law? :idea:

finally silverstone makes single dual and quad rail - 4 x18 amp 60a combined max or dual 30 amp or single 60 amp - which is better and why?

it appears that the quad rail is more efficient in the case of silverstone.

pc power & cooling's new 750 single rail - looks good at $200 retail and 83% efficient - is it as good at the $500 psu? probably not - since its 2/5 the price!

thank you for your feedback!! :D 

PS: i have used both dual and quad and notice no difference?

mr psu-eagle: silverstone makes 60amp dual rail - 2 x 30 amp rails with 35 amp peak

they have quad. dual and single rails

i went with cross conected 750w quad rail they work great less then $150 shipped 54amp peak.

thx for the imput!

dual rail:

well my striker 750 handles my maxed out x1950's (699mhz cat 7.2 oc) in crossfire, my smoking e6300 (wimpy 2.8ghz)at 38c at 100%, my quad 160gb raid 10/0 and the mighty lights and fans!

don't laugh - i have 6 12" cold cathodes and 5 12cm lighted fans - probably 100watts

and there is no hot air blow out the psu - at idle - none!

i think that pc power and cooling psu is totally the bomb! its really nice - but is it really better then then 70 amp silverstone?

note: it appears some people are having issues with the dual rail system - i think they are hooking both gpu's to same rail, with peripherals, and not looking at the directions? but there may be more here?

lastly mr psu-eagle-- i am always covering your back - the silent dragon high in the sky!
