Thermaltake ToughPower SFX 450W Power Supply Review

Over Power Protection and Max Wattage

Although power supplies always come with a rated power supply, or at least we hope they do, it is never unusual to see them perform beyond that amount. When things are pushed too hard, however, it’s exceptionally important to know that protections are in place to shut your system down before the risk of any component damage starts to present itself.

Under our testing, the Thermaltake Toughpower SFX 450W managed to achieve a wattage output of 593 before the protections successfully kicked into place. Given that this is nearly 25% over the rated amount, this is exceptionally impressive for sure. Albeit, as above, going over the rated limit is never recommended, but at least if you do you know that the OPP is there to ensure you don’t cause any small fires!
