As explained, the Thermaltake Smart 730 W model uses a different platform from the 630 W model.
The Thermaltake Smart 730 W is clearly an entry-level power supply, having very good performance for this market segment, with efficiency between 80.6% and 86.4%, voltages closer to their nominal values than required (three percent regulation) most of the time, and noise and ripple levels below the maximum allowed. It is also worth mentioning that the cables are not too short, which is a problem that plagues some entry-level products.
However, the +5VSB output presented +4.72 V during our full load test, a number that is below the minimum allowed.
Even though this unit can really present efficiency above 80%, officially, it doesn’t have the 80 Plus certification, so the manufacturer couldn’t claim 80 Plus certification or use the 80 Plus logo. As previously explained, the company was already contacted in order to get this unit certified.
Also, this power supply is too expensive for what it is, as for the same price you can buy a 750 W power supply with the 80 Plus Bronze certification. On the other hand, if you live in the U.S., you can get a USD 15 mail-in rebate card, which makes this unit cost USD 85.
