Continually, we find ourselves looking at great Corsair PSUs – the HX, the TX and now the VX have all performed fantastically. The VX550W does exactly what it says on the tin and even though our model dropped a fraction below 80 percent load under significant 3.3V and 5V stress, it's very unlikely they'll ever hit these sorts of values in a real PC. Where it matters the Corsair VX550W works exceptionally well, hitting upwards of 85 percent efficiency throughout the rest of the tests.

We'd be torn between the significant benefits of buying modular, versus the extra cost and slightly lower power. I used the VX550W in my own home theatre PC for a few months prior to this review and it was nothing but fantastic. In this instance, cable management didn't matter since there was a large enough case that was designed just to be super-low noise: in that respect it worked perfectly. I even had to install an extra cathode it to tell if the system was on or off, simply because it was that quiet I couldn't hear it unless my head was all of two inches away.
