Gigabyte Greenmax Series

Hi mate, firstly here's a link to a page with a similar question to yours check it out might help; http://www.tomshardware.com/forum/id-1656189/gigabyte-greenmax-psu-good-system.html

Secondly that is a good psu and you should defiantly be happy with it

Lastly if you're curious about wattage required, go to the thermaltake psu calculator (just google it) and you can find exactly what amount of wattage you need
 
Solution
The one im afraid of is that im about to upgrade my pc someday with an i5 3570k and sapphire r9 270x(which needs minum of 500w) maybe that psu may not handle it. i got less time to choose psu and seasonic and antec arent available.
BTW mate, is this 550w psu good for my future specs, since the box says that its SLI ready and got 2 6+2 gpu pins
 
Did you mean to link a page?

I would highly recommend a 750w psu

However it's easy enough to just check that your getting the recommended wattage, just google thermaltake psu calculator, it's what I use and is great for figurin out our system wattage
 
Done dude thanks for the answers. my dream specs will take 430w and is good 😀.
at first I thought that this psu is bad like aerocools. coolermaster etc. now that you said and proved that this psu is good then im confident now. but i still admit that this is worse than seasonic and antec. but its still good.

thanks by the way
 
Don't get me started on cooler master or ill rant for hours and hours hahaha 😛 I'm running a thermaltake Evo 2.0 blue 750w and I'm loving it so good :)

Best of luck with the build mate, hope it all works out for you!
