Corsair TX550M scores 9/10 and get the "Recommended" award at Jonny Guru

"Corsair's new TX modular series gets a recommendation here today. And it is well deserved. This unit is exceptionally good for a little 550 watt unit. It runs cool, it's incredibly stable, and it keeps ripple and noise under half of the ATX specification. No, it's not the latest and greatest when it comes to the push toward higher efficiency, but let's be honest here... the difference to your wallet between Bronze and even Platinum isn't as great as you might think. You could easily do worse than this unit right here."
