tpage title=”Conclusions”]
We were really surprised with this power supply. Since it “only” has the standard 80 Plus certification, we were expecting it to achieve, in the best case scenario, efficiency between 80-82%. And since the latest power supply from Cooler Master with standard 80 Plus certification we tested, GX 750 W, proved to be a true “bomb” with efficiency below 80% and noise and ripple above the maximum allowed, to be honest we were not expecting much from Silent Pro M 600 W.
We are happy to be wrong! It delivered high efficiency between 83.4% and 86.6% most of the time (at full load efficiency was at 81.0%), the main voltages were always within 3% of their nominal values (ATX12V specification allows them to be up to 5% distant, so this mean that voltages were closer to their nominal values than required) and noise and ripple was always low. Sweet!
Then we have pricing. It is being sold for USD 100 in the United States, which puts it as a no-brainer against its main competitors, like Zalman ZM600-HP (USD 124 and lower efficiency) and Zalman ZM600-RS (comparable performance but costing USD 115). Of course it presents a far better performance (especially on efficiency) than more inexpensive products – in fact it is cheaper and a way better product than Cooler Master GX 750 W.
As one final note, the manufacturer website says that this unit has “Japanese capacitors.” Several manufacturers are with this problem on putting on plural when only the capacitors from the primary are Japanese. They should change this phrase to “Japanese capacitors on primary” or similar wording to avoid users thinking that all capacitors are made in Japan, which is not the case.
