It will not blow up your system, that much I am sure of.
Get this one instead:
it got 9.9 out of 10 on jonnyguru
It's ok. Not as good as the Gold G2's.
It's a good 2nd tier PSU but it's not 1st tier which means it's not the best. I would get something better like Corsair because the PSU is what powers your whole PC, so getting a good 1st tier PSU is essential and very important if you want your PC to not be at risk because of a 2nd tier PSU. So you could get the EVGA PSU and save money but put your system and money at risk. So I would say go with Corsair.
