Hi guys .. I'm looking for an 80 PLUS certified power supply which is about 350W to 500W ? Ideally should really be 350W or 400W as its going to be used with a very very light load PC ... 80 PLUS power supplies are generally available for heavier loads and so are quite expensive, hence I'm hoping someone can assist me in finding a lower wattage PSU which is 80 PLUS certified ..
