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 AZZA Platinum 1000W power supply, 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 2% regulation from start to finish with a total drop of .20V. The 5V rail managed to stay within 3% of specification with a total drop of .16V from start to finish. Moving towards the 3.3V rail, we see that regulation was within 3% of specification with a total voltage drop of .08V.
DC Output quality for the Platinum 1000W was great and well within specification. During Test 1, we saw 12mV of noise on our scope. When we increased the loads in Test 3, the ripple climbed to 19mV at a little over half load. During Test 6 under a load of 1000W, the oscilloscope showed a maximum of 33mv on noise on the 12V rail.
The AZZA Platinum 1000W is rated for 80 PLUS Platinum efficiency. This means that the power supply must perform at 90%/92%/89% efficiency at 20%/50%/100% loads respectively. As you can see, the Platinum 1000W passed on our bench, and wasn't close to failing at any point.
While AZZA may be new to us and our readers, the power supply in front of us is most certainly not. We've seen it in many different forms from a plethora of manufacturers and all have given us the same result. The AZZA Platinum 1000W is a solid power supply inside and out. Knowing that it is a reference Super Flower Golden King unit helps and there is little to say about this power supply that we've not said before. It is a fantastic unit all the way around.
Performance is great out of the AZZA Platinum 1000W even if the noise suppression isn't as strong as we've seen on other units. Considering we've seen many of these in the past and this one has displayed the "worst" ripple to date, we would happily pick one up and stick it in our own rig without hesitation. It may have the worst ripple we've seen from a reference Golden King, but it isn't even anywhere close to being out of specification, so it's not an issue at all.
The thing that bothers us a bit is the short warranty for the unit. It isn't that the warranty is short that bothers us, but that other identical units have a substantially longer warranty. We just don't understand why they would offer what has become a sub-standard warranty when the company manufacturing it for them offers it with a longer warranty themselves. It just doesn't make sense, especially when trying to make your product stand out in an already crowded market segment.
Aside from being a quality unit though, the price is what really sets the AZZA Platinum 1000W apart from the competition and that is most certainly one way to make a name for yourself. If you're seeking a quality 1000W power supply and doing it on a tight budget, you won't find a better bargain especially if you can catch the power supply on sale.
