OCZ Fatal1ty Series 1000-watt Power Supply Review

Test Results


Our load tests utilize a couple of FAST ATE active load testers and a variety of other equipment such as an oscilloscope, power conditioner, temperature probe and a power consumption meter. You can read more about our standard testing approach here.


The tests performed are based around six conceivable setups that are out there and progressively load down the PSU up to the power supply's limits or 1000W, whichever comes first. Since our test equipment's limits are equal to that of the OCZ 1000W Fatal1ty Series PSU, we can test it to the maximum.




The above tests represent typical loads that we have measured from various systems and are meant to give a rough idea of where your computer might fall in line with our tests. Please keep in mind that each system is different and actual loads can vary greatly even with similar hardware.




Let's start by taking a look at the voltages to see how well this unit did during testing. Starting with the 12V rail, we see 1% regulation from with a total drop of .15V from start to finish. The 5V rail stayed within 2% voltage regulation and displayed a total drop of .09V. Moving towards the 3.3V rail, we see that regulation was again within 2% with a total voltage drop of .06V.


DC output quality was excellent from start to finish. Starting out, we were barely able to see a ripple on the scope during Test 1 where we measured noise at a very low 7mV peak to peak. This steadily increased as the loads also increased. By the time we had reached around 50% load, the unit ripple had crept up to 14mV. Under Test 6, we saw that the noise on the 12V rail had crept up to 23mV.


The OCZ 1000W Fatal1ty Series PSU is rated for 80Plus Gold efficiency. This means that the power supply must perform at 87%/90%/87% efficiency at 20%/50%/100% loads respectively. As you can see, the 1000W Fatal1ty Series had no trouble achieving this while on our test bench.



Final Thoughts


OCZ has done an amazing job by bringing the 1000-watt Fatal1ty Series power supply to the market. Strictly from a performance standpoint, the power supply is an excellent unit. This is the first unit we have seen in a very long time that managed to achieve 1% voltage regulation on any rail and it was very close to achieving it on the 5V rail as well. DC output quality is among the best that we have ever seen and couldn't be any better.


Topping it all off, efficiency is right where it should be for an 80Plus Gold power supply. If OCZ had managed to pull all this off with Platinum efficiency, this could have easily been one of the best units we've seen (and probably will see) all year.


Of course, the most important thing to talk about in this unit is the inclusion of individually sleeved cables. Sometimes it takes a bit of risk and for someone it say, "let's just do it." OCZ has managed to set itself apart from the competition with features this time doing just that and while it may be a bit risky, we feel that it is something you are going to start seeing quite a bit more of now that someone has taken the first step to bring this mainstream.


As with all things new, trendy and cool, it comes with a bit of a price premium. Even at the price of $199.99 after rebate, the unit is somewhat pricey compared to the competition, but also represents a very fair deal if you were to compare the price of a power supply with similar performance and the cost sleeving the cables yourself. This route saves you the hassle and the time as well.
