This ATX / PS2 power supply unit (PSU) has a real power rating of 350W (continuous). The eco-friendly design allows APN 85+ series to reach up to 85% efficiency. APN series also protects your PC by providing complete protection (OCP, OVP and SCP). APN series does the job efficiently and reliably, making it a stable power supply unit built to satisfy the demands of users looking for entry-level power or the budget-minded system builder. The efficiency of this power supply meets the 80 PLUS Bronze requirements at 230V input. However, as EPRI only test power supplies at 115V input; this PSU cannot be certified by 80 PLUS (as implemented by ECOVA). This also meets the Energy Star Version 5.0 Power Supply and Power Management Requirements for Computers: Effective July 1st, 2009.4199447
