The ModXStream-Pro series from OCZ Technology seems to be a stable power supply unit priced for the mid-range market.

The device has a modular design that allows you to plug the power cables yourself, according to your needs. This would please many users, mostly gamers. The 140mm fan that speeds up/down according to the produced load, meaning that the PSU will not produce noise during your daily PC use. The provided 600 Watt of power is enough to efficiently power your dual graphics card configurations. After all, the product is SLI-certified. But still, a triple/quad SLI setup would possibly require more power.

We would like to see longer power cables inside the box for easier installation in The power full size PC cases.

Our basic performance tests did not show any issues. Thought the configuration of our test PC was power demanding, the PSU showed stability and efficiency. Of course, further testing using specialized equipment would be required in order to come up with safer conclusions. For the end-user's perspective, the device will do the job.

OCZ's 3-year PowerSwap replacement program warranty, gives you no more endless return-for-repair loops.

Adding to all these the retail price of the OCZ ModXStream-Pro 600 Watt PSU, which is under $100, we can safely say that we have to do with a safe buy here, at least.
