I have the psu and its the most annoying thing ive ever baught, despite corsairs "reknown" quality everything i have baught from them was broken out of the box, that psu makes a high pitch ring that i can hear throughout my house weather the pc is on or off, my corsair dominator ram wouldnt boot, and my h110 came with 2 broken fans. my 600watt silverstone on the otherhand is silent and been pumping out 590+ watts no problem with no crashes, definatly going to get a bigger one soon though lol.
1.most of the times
2.probably but try get a 80+ bronze so you dont burn your house
How i've waited for you to come, I have been here all along, now that you've arrived please stay a while, and I promise I won't keep you long, I'll keep you forever
