appreciate it if you guys can help me out to configure a good case and PSU.
ATX means form fartor ATX normally
but I think these are a mfg based random names & numbers
+12V Rails – 1
Output – +3.3V@30A, +5V@45A, +12V@26A, -5V@0.5A, -12V@1A, +5VSB@2.5A
for the one you picked
+12V Rails – 2
Output – +3.3V@30A,+5V@30A,+12V1@18A,+12V2@18A,-12V@0.8A, +5VSB@2.5A
for this one

12v is the auxiliary power on video cards so the 2 rails total (36A) a higher output than the single rail (26A) and spread the stress on the PSU better
ATX is a standard not only based on form factor but connections, power regulations and many other specs.

Read up on the different versions there.
The Rosewill PSU will work since it’s got a EPS12V connector but it has a weak 12v rail. It will not be enough to power a decent graphics card. Remember that the 12v powers everything from hard drives, dvd drives, graphics cards, fans. Without the 12v plug the system will not even start so enough amps is mandatory especially for i7 build. It’s labeled incorrectly. It can’t be ATX 1.3. It’s definitely above 2.0 since it got a 24pin motherboard power connector. The PSU is also not very efficient and the ripple would not be satisfactory I can tell. At 70% efficiency the rated 26A on the 12v would only be near 20A. Not nice at all. Rosewill isn’t a very good brand I would rather get something else like Corsair, Seasonic, Antec, Thermaltake.
tanx for the info. is this better….there is no info on 12v rail for this one,,,

+12V Rails – 2
Output – +3.3V@25A,+5V@25A,+12V1@18A,+12V2@18A,-12V@0.3A, +5VSB@2.5A lower spec on the 3.3 & 5
That one is a heck of a lot better. Or
Spend $10 extra and get this.

Just to avoid confusion I think you meant 36Amps and 26Amps where you said Volts
