Hi guys i heard there is a close relationg between COIL WHINE & psu. So what would be a good 550-700w psu for msi gtx 970 gaming 4g which is good but not much expensive? Please suggest the one you personally experienced with msi gtx 970 gaming having NO COIL WHINE. I am really afraid of the coil whine fact and i really don't want to get one in my gpu. So as always help guys. Waiting for your reply........
