Hec doesn't have a great reputation. That one has full range active PFC, but is not 80+ certified. I didn't find any competent technical reviews, but I found this: http://hardforum.com/showthread.php?p=1035476407
, and, looking closely at its label, I have to agree that I'm not exactly sure what you'd be getting. You wouldn't be stressing even an 800W PSU, but I wouldn't buy one. There's a lot more to a quality PSU than wattage. A 550W Antec, Corsair, or Seasonic would handle any single graphics card except for a HD5970 or GTX480.
