Hi. First time building, and a bit clueless. I'm going to upgrade my crap PSU and GPU to a Corsair GS600 and a 7870. I don't know if they both are compatible with my mobo (title). I'm a little concerned about installing the PSU, as I fear I could mistake some cables and make the computer go boom haha. Are there any good psu installing guides you would recommend for a first time builder? Thanks
