At a first sigh creating a 1,000 W power supply using the same standard ATX size seems to be a great idea, but the problem is that power supplies on this range simply don?t fit such small form factor. OCZ opted to use an intricate design using two stacked printed circuit boards and one small 80-mm fan on the rear, leading this product to face serious thermal issues: when pulling the full 1,000 W the temperature of the power supply skyrocketed to 68º C (this is so hot that you can actually burn your fingers by touching it).
The 80-mm fan wasn't capable of correctly dissipating the amount of heat produced by the power supply and also generated a lot of noise, as it was always spinning at its full speed during our tests.
Even though it is cheaper than other 1,000 W power supplies available on the market and it can truly deliver 1,000 W at 50º C we simply can?t recommend this power supply mainly because of its working temperature, since it will overheat your system.
