Good day.

My PC rig:
i5-3570k
asus p8z77 m pro
EVGA GTX 650 ti BOOST 2gb SuperClocked
1TB Seagate Hard drive

Now, Questions are:

1. Is the power supply above, good for these parts?
2. If im about to use SLI, adding 1 more video card, will this PSU be sufficient? (well the package contains 2 6+2 pin for pci-3)
3. And I dont get this, we all know that this is 550W PSU, the box says "700W Maximum Output", so what does the 550W(in the label) and 700W maximum output mean?
4. And the most important question, is Gigabyte(Greenmax) a good power supply?
 
Solution
1 Size wise fine quality wise OK but a lot of better units on the market.
2 suggest going at least 600watts but a higher quality 550watt would handle it.
3 550 constant 700 peak wattage.
4 OK not great.

^So dude bout your answer in question 3 . so for example. my whole system unit consumption is only 300watts(just an example). and i have that power supply. so the consumption on my electricity is 550watts? or same the pc consumption which is 300 watt?
 


If your parts are consuming 300 watts then you will be pulling 375 watts from the wall because of the 80% efficiency. The 550watt constant rating means that it can provide 550watts of DC power constant but can peak up to 700watts without shutting down.
