Hi guys, looking to upgrade my 620W seasonic PSU as i think its time for an upgrade as i have recently been upgrading all my other parts, want to get a top of the line psu ideally from corsair or another seasonic i dont mind where tbh, and it needs to be 800w + been looking at the 1kw psus, my system currently has a quad core oc'ed, water cooling system, 4 mechanical hard drives, and 2 ssd drives, 2 sli gfx cards and also a LOT of blue led lights etc thanks
