The Fractal Design Ion+ 660P achieves good performance and dead silent operation. Its low noise output under all conditions is among its significant advantages over the popular Seasonic Focus Plus Platinum. The latter performs better, but it has 25.35 dB(A) overall noise output, while the Ion+ 660P stays much lower at 13.74 dB(A). With a street price of $109.99 (£104.99 in the UK), the Ion+ 660P is about the same price as its main competitor and offers a quieter experience but a bit less performance.
