The 1 year warranty tells you that it's a piece of junk.
Here's a review conclusion.
The Bottom Line
The Raidmax RX-1000AE is quite the contradiction and this results in a passing, but not exactly impressive, unit. There were no tests in which this unit failed, but that does not necessarily make its performance outstanding. Indeed, when compared to its marketing this unit was sorely lacking on the efficiency front and the 1 year warranty support for this unit is laughable. On top of that, the voltage regulation was not great and the unit was a bit noisier in the upper 20% of its output than we have seen from a number of other units in this DC output capacity range. However, all is not lost as this unit did post significant improvements over the previous unit based on this basic design from Andyson we reviewed when it comes to DC Output Quality, the general build quality is good, and at $149.99 this unit represents the one of the cheapest 1000W units on the market today that has passed our testing. As such, on a strictly dollar based value assessment, this unit is a good buy so long as users are only looking for a power supply that will provides 1000 watts of power inside of the ATX12v specification limits and nothing more. Raidmax has on its hands a passing first offering, now hopefully Raidmax will take this unit and build upon this to develop some truly excellent products. And someone needs to do something about the fictitious 80Plus efficiency numbers that are not represented properly in the retail product.
