Any Seasonic unit or XFX ( all are made by Seasonic ) unit. Any Corsair except the CX or RM series. Pretty much any Antec, PC Power and Cooling, Silverstone, Enermax, OCZ or the higher efficiency Rosewill units. Give me a store or country and I will find you the best deal.
^ The EggXpert tier list is a good place to start. Stay in tier 2 and up and you will be fine.
