But beauty is more than just skin deep. The Hiper 880W PSU delivers excellent voltage regulation and the overall efficiency is very good. Under normal operating conditions (below 600W load) the Hiper 880W is very quiet. The PSU comes fitted with a good assortment of hard-wired cables and connectors that can support dual, high-end video cards. And let's not forget 8 USB 2.0 ports and one USB-style mobile device charging port for added connectivity.
