Thermaltake Smart BM2 750w Power Supply Review

Efficiency

Despite officially being 80-Plus Bronze efficiency rated, the truth is that the Thermaltake Smart BM2 actually performs well beyond that remit. In our testing, we saw results that were actually more in line with ‘Silver’ and even occasionally tiptoeing into ‘Gold’ territory.

For a consumer, however, this is all fantastic news as despite nearly being more in line with ‘Gold’ in our testing, this is still officially ‘Bronze’. As such, will carry a price tag more in line with that grade rather than the higher tier. So, in other words, this is already looking to provide consumers with some excellent performance to pound (or Dollar/Euro) value.

PFC (Power Factor Correction)

Our experience of Thermaltake power supplies has always presented excellent results in our PFC testing and this is certainly no exception here with the Smart BM2. While starting off a little on the low side at 20% load (which is perfectly normal by the way), the results quickly ramp up the harder you ask this PSU to work. And with it achieving a score of 0.97 at 100%, this is definitely very good indeed!

Voltage Regulation

Consistency is the key work with voltage regulation and the Smart BM2 hits this nail right on the head. As can be seen in the results below, the average deviancy seen across the various load outputs was exceptionally low. The only major of mild interest was the -12V rail which did seem to undervolt by a fair margin. Given that this is rarely utilized in modern PC designs, however, we do not see this any cause for concern.
