Hello all,

I tried to google this, but the results I found were hit and miss. I'm trying to compare two PSU's.

VS
http://www.newegg.com/Product/Product.aspx?Item=N82E16817438057

I have the compare on Newegg up, but it's all in chinese to me. If you don't mind, I've some questions.

1. What does Input current do? Is more better?

2. Same question for Input Voltage?

3. What is input frequency rate, appears 50/60hz is normal?

4. Not sure about how output works, I see a bunch of +5V@24A and @20A, and a few other voltages, not sure what it means

Sorry I know these are probably stupid questions :< Thank you!

1. + 2. = in...

1. + 2. = in the US we use 110v, in europe it's 220v. To keep things in simple terms it's just the way electricity is delivered to your house.


3. Same as 1 + 2 in the US it's 60hz, in europe it's 50hz


4. All you need to worry about is +12v rail, and the amps it is capable of handling, the higher the better.


The P2 is the better unit by the way. Nice deal on it too.
