Price Per Wattage:

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.

Pros:

• Good voltage regulation
• 5 year warranty
• Plenty of connectors
• 80 Plus Bronze

Cons:

• Ripple/Noise levels could be better
