Unique Features

High Efficiency: The Thermaltake ToughPower 550 is advertised to be over 80% efficient. We expect this unit to be very similar to Antec’s Neo HE 550 since both are advertised as high efficient PSUs rated at 550W.


The Thermaltake ToughPower 550W is priced at $129.99. So, this unit weighs in just a little higher than the Antec Neo HE 550W. These PSUs seem to be pretty even as far as specs and pricing is concerned, so it will come down to performance when judging the lower wattage units!
