OCZ ModXstream Pro 500wUp Close
As with a lot of things, it's what's inside that counts. This is where the PSU performs its magic, transforming the unfriendly AC into computer friendly DC current: breaking down the 240VAC into the various low voltage rails. After removing four screws from the top of our unit, we were in...
The internals of the ModXstream Pro are split into three sections, with MOSFET heatsinks dividing each section up. In the top section, we have a single large capacitor. It is preferred to have multiple smaller capacitors as this reduces power ripple, but it shouldn't be too big a problem. The capacitor appears to be made by EPCOS, a German manufacturer and features the following markings: 330uF / 400v / 85c. In the middle section we have two transformers, one for the 12v and the other most likely for 3.3v/5v.
Being a modular cables not all the cables are attached to the PSU. Instead only a few of them are left attached to the PSU and the rest are detachable. This way only the cables you need are attached, minimising excess cable mess within your case.
Here we have the dual PCI-e Connectors and molex leads. The 8-pin PCI-e can be converted to a 6-pin lead by removing the two extra pins. The Molex connectors have two standard molex connectors, then a floppy connector on the end. It would have been far more useful to have three molex connectors, with a floppy adaptor in the box for those that still need them.
