If you're one of those gamers who always has to have the latest and greatest video card, the recent release of nVidia's GTX 470 and 480 may have left you in a lurch and scrambling to find some reserve power. With maximum usage exceeding 300W on the 480, which is more than ATI's 5970 or nVidia's GTX 295 dual-GPU cards, the 480 represents one of the most power hungry video cards ever to exist. Throw two of them in SLI on a modern quad-core or greater system and you're in for 900W or more of pure hurt. It wasn't long ago that a 1000W power supply seemed like gross overkill and now here we are talking about one being barely adequate. Luckily power supply manufacturers have been keeping up with the demand and more options for 1000W+ systems keep popping up every day.
Sparkle Computer Corp, the same company that has manufactured nVidia-based video cards for many years, is now branching into the power supply market and looking to make a big splash doing so. For review today we have one of their new Gold Class power supplies in the 1250W variety, and according to their website they also offer a 1000W unit in the same series. The 1250W Gold Class gets its name in part due to the 80Plus Gold rating, reserved for those power supplies exceeding 90%+ efficiency. Couple that with six +12V rails rated for 20A each and you've got a 120A claimed peak load handling capability, that's a whopping 1440W!
Join me as I take a closer look at the Sparkle Gold Class 1250W power supply.
