Product details
The be quiet! Straight Power 11 Platinum 1200W sets standards for whisper-quiet systems with outstanding efficiency. This power supply has been awarded the 80 PLUS Platinum certification for its excellent efficiency. Its very high efficiency exceeds 94/92/90 percent at 50/20/100 percent load (at 230 volts input voltage). Less excess energy means less unnecessary heat generation. This also protects other components, allows the fans to operate more quietly, and helps you save money in the long run through lower electricity bills.
