I was just about to invest on a Corsair HX1000W Power Supply unit but 5 days ago, Corsair announced the new Professional Series™ Gold AX1200 fully-modular power supply units, with 80 PLUS® GOLD certification. I am definately getting this new monsta PSU, guess i have to wait longer for it as they have not announced the price yet and it will only be out in July 2010.
