i need to upgrade my psu...
i really dont know much about amps and volts.... take a look at this stuff right here...

this one is 600 watts... 12volts at 22amps...
now look at this one:

http://www.newegg.com/Product/Produc...82E16817190003

this one is 500 watts... 12volts at 30amps...

i dont know which one to choose: should i get more watts or have better volt/amp thing?
can you explain how this works? I guess having better amps on the 12volt thing is better because its 'stable'?

oh, and if you can explain any other essential things that i need to look for when im purchasing a psu that would be helpful. anything that would benefit me would be nice

I personally do not know any more than you at this point but did this search and am reading up on it

There is a handy link from the custom pc business we use:-

Its not 100% upto date which is a shame, but the later CPUs dont draw much more - perhaps even less than the most demanding ones shown.

As for the best make to go for, I use an Enermax PSU in my machine; its silent and gives a good constant voltage across all rails - and comes with a 3 year warranty, which proves its good quality. Seasonic are good too. Apparently Hiper are quite good - although i have heard the latter can be iffy under a full load.

If you can afford a modular one, then thats cool - reduces cable clutter as you only use the number you need. Make sure it has the correct number of PINS to match your motherboard ie 20 or 24.

Avoid cheap PSUs - when i had my Dell i picked up a replacement Dell PSU for £3.75 ! light as a feather, PC kept blue screening and didnt last. Despite warranty, i cannot afford for something to breakdown, so spend £30 minimum on an okay one or ideally £50 - £75+ bracket and go for reliability!
