Maximum PC: Is your power supply (PSU) certified to work with Intel's 4th generation Core processor (Haswell) line without hiccups? Lest there be any doubt, EVGA specifically lists its new 500B PSU as being Haswell ready. It's also 80 Plus Bronze certified with up to 85 percent efficiency under typical loads, a feature that's not always found on PSUs aimed at users on a budget.
