The OP650

This PSU has a full matt black exterior which is a nice change from the flashy chromed surfaces of many power supplies out there at the moment. The top has an indented Silverstone logo that really works well with the matt finish.

The rear of the unit has a full honeycombed surface to allow air to exhaust freely from inside the PSU out of the back of the case. Honeycomb shaped grills are used as they afford the most freedom for the movement of air without having a completely open backed unit.

The Olympia is fitted with a single 120mm fan with black fan blades and a black fan grill. The centre is an ugly beige colour with the Silverstone logo on it which would really bring down the style of the PSU if it was more visible.

Unfortunately this Silverstone offering does not feature modular cabling so the front looks rather bare. However, there is a small grill just above the cables' exit hole that allows air to flow over a nearby copper coil.

The PCIE and motherboard power cables are braided which really improves their look, giving them a much neater appearance; it's just a shame that the braiding is limited to only these cables. It is also a bit of a let down not to see quick release clips on the molex connectors. it's little things like these that really make power supplies stand out from the crowd.

The Single Rail

An interesting feature of this power supply is that instead of fitting the standard of several 12v rails, the Olympia features only one. There are several advantages and a couple of disadvantages to this method of PSU production. To read about power distribution among rails have a look at our glossary entry here.
