Corsair TX550M 550W Power Supply at $89.99 = $0.16/Watt (02-2012)
The Corsair TX550M power supply comes well-packaged with good build quality and a decent set of accessories.
The DC voltage load regulation is generally good, with a worst case -3.6% on the +3.3V rail. The noise/ripple values, on the other hand, could be better although it manages to stay within the limits set down by the ATX12V specification, but only just. The efficiency/power factor correction of the TX550M is on a par with other power supplies in this class, as tested by the OCC power supply methodology.
The Corsair TX550M is a decent enough offering that brings the option of modular cables to the ever-popular TX range at a competitive price. It's well made and performs well, so it's certainly capable of reliably powering a powerful gaming PC with a single high end graphics card.
