PC Power & Cooling Silencer 910 Power Supply Review
Conclusions
Contents
PC Power & Cooling Silencer 910 is a terrific high-end power supply, presenting an outstanding efficiency of at least 85% if you pull up to 80% from its labeled capacity (i.e., up to 728 W). At full load (910 W) efficiency was 83.4%, which isn’t bad at all! Noise and ripple levels were always very low.
Notice that we are more rigorous on our tests than the folks at 80 Plus; they test power supplies at 23° C (a temperature impossible to be achieved inside a PC) while we test them at least double this temperature. Since efficiency drops with temperature, our results are lower (but more realistic) than those reported by 80 Plus.
This new trend of using a DC-DC converter design on the secondary is proving to be a winner for efficiency, as all power supplies we’ve reviewed using this kind of design achieved high efficiency in our tests.
Another highlight from this product is the number of SATA power connectors – twelve – more than enough even for the über nerd.
The only drawback we see on Silencer 910 is the lack of native support for SLI and CrossFire with three or more high-end video cards. If you want to run three or more high-end video cards at the same time with this power supply you will need to convert standard peripheral power plugs using adapters.
The price isn’t bad for a high-end 900 W power supply. It costs USD 10 more than Topower PowerBird 900 W, but presents a higher efficiency. On the other hand this model from Topower has a fully modular cabling system.
In summary, Silencer 910 is a very good option for the high-end user looking for a beefy power supply with very high efficiency and ultra low ripple and electrical noise levels.
