OCZ ModStream 520 W Power Supply

A Look Inside The the Power Supply

Since we are very curious, we decide to open the power supply to take a look inside it.

The first thing we discovered was that this power supply is manufactured by Topower.

For a layman, it looks like any other power supply. But if you pay really attention you will see that OCZ uses better quality components inside their power supply, like transistors that can really deliver the current claimed by the manufacturer, better heatsink for the transistors, better electrolytic capacitors with higher capacitance and a lot of extra filtering to ensure very stable voltage outputs with no spikes or noise. In Figure 11 you see part of the input line filter, which "generic" power supplies simply don’t have.
