I went to Best Buy to pick up a Corsair CX750m power supply. On the website it's the one with the green lettering. This one is in a blck and yellow box and has grey lettering. It's the same model number. I thought it was just the previous generation but on the box it says 2010-2015. I also want to know if this is a decent PSU I'm replacing a SILENCER 750 watt one. The silencer still works fine it's been going strong for over 7 years. Should I return the corsair and use my silencer or keep it.
