Seasonic X-Series 660W Modular Power Supply Review
" Not all PC users require extreme systems that use over 700+ watts during operation. After the successful release of Seasonic's 550W, 650W and 750W power supplies, it looks like there are a few extra additions to their X-Series power supply line. One of them is the high wattage 850W PSU, and the other is the new 660W PSU that we are taking a look at today. Seasonic has been making high-quality power supplies ever since they hit the market two years ago. Not only is their new X-660 660W power supply 80Plus Gold rated, but also comes with a quiet fan. The PSU’s fan does not kick in till the user reaches 20±5% load, and it maintains a 16dB(A) acoustic noise level until it reaches 50% load. From that point on the fan speed begins speeding up, still maintaining low acoustic noise. The Seasonic X-660 750W power supply is also 100% modular, which makes it very easy to install and prevents large cable messes from accumulating. "
