SilverStone Olympia OP650 Review

Compared to former power supplies from Silverstone we can say that the company made an aggressive but logical step forward. With 650 watt it is one of the higher performing power supplies and therefore not suiting every users needs. With an efficiency of over 80% at lower loads (with 230VAC) it could run a decent medium class PC without wasting too much energy.

Due to the increasing temperature of our tests, we saw the voltages drop, especially on the lower voltage rails. The chosen high-end components have been a good fit for the most part but heat is still an issue. The new crew of engineers has come up with a good PCB design as well. From the high overall quality, one can literally see the robots installing these components.

The heatsinks have a very clever shape to let much air through to the PCB to cool down most of the components where they stand. They have a decent thickness as well which allows for a lot of heat conduction. The temperature of the heatsinks was average but we have seen colder ones. As for fan speed, the produced noise level was not the best result we could have hoped for, but it seems to be necessary to cool down the power supply to keep it working properly. We would love to see Silverstone take a second look at the fan speed and adjustments. The sound issue shouldn't be a real problem for most users who chose this PSU, as they will not be able to load the PSU anywhere near 80%. Not many people will ever hear this power supply with full load.

Protection features work fine in this model. The power supply correctly shuts down with any potential threat to its life such as over current or over power. Our short circuit test on each line during different loading stages had a positive outcome too with no damage to our unit.

In case of efficiency the OP650 has surprised us in a good way. At 230VAC it reached 80% efficiency with the impressively low load of 20%. At a medium load we saw an impressive 83% efficiency which held on until our highest load tests. At the lowest input of 115VAC we could only reach an efficiency of 81% which is still a very good result. In case of standby efficiency we measured just about 1.19W at 115VAC and 1.7W at 230VAC which is not a very high energy loss: exactly what we would like to see.

The price of the OP650 is just about $160 in the United States and around 139€ in Europe which is a reasonable price for a 650W power supply. It is a good price for the quality and performance this power supply brings to the table.

The build quality of the Olympia series is unmatched from other series of Silverstone PSUs which makes it the highest performer the company offers. We are looking forward where this leads in the future and what power supplies Silverstone will put out next.

Jonny Guru did one a while back and gave it a 9/10, lowest score was an 8 for aesthetics.

This isn't really news. This is a review.

@ The JonnyGuru discussion. There is only one section that I care about. Performance.

My friend has this with his quad core, 4gb of Gskill and X2900XT and it runs like a champ.
