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 higher than that of the FSP Aurum Pro 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 .16V. The 5V rail managed to stay within 2% of specification with a total drop of .14V from start to finish. Moving towards the 3.3V rail, we see that regulation was within 2% of specification with a total voltage drop of .05V.
DC Output quality for the FSP Aurum Pro 1000W was good and well within specifications. During Test 1, we saw 17mV of noise on our scope. When we increased the loads in Test 3, the ripple climbed to 34mV at a little over half load. During Test 6 under a load of 1000W, the oscilloscope showed a maximum of 49mV on noise on the 12V rail.
The FSP Aurum Pro 1000W is rated for 80 PLUS 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 Aurum Pro 1000W passed on our bench, and wasn't close to failing at any point.
The FSP Aurum Pro 1000W is an awesome unit. It exhibits all of the same qualities that we found in the 1200W model, except that it is cheaper. As a matter of fact, it is identical to the 1200W model in every way that we can find except that it has 200W less power available and is roughly $25 cheaper. It literally has the same connectors, cables, accessories, etc.
You would think that there would be more differences and there usually are, but that just isn't the case here. One almost wonders if they didn't just make the 1200W unit just to say they have one since they didn't put any effort into differentiating it some more.
That being said, the performance is just what you would expect out of a power supply priced right in the middle of the market. DC output quality is very respectable with the 12V and 3.3V rails being within 2% of specifications and the 5V rail just barely creeping into the 3% range. The noise suppression on the 12V rail could be a little bit better, but you can't have it all with a unit that is competitively priced. The efficiency is great though for a unit priced as such.
Even though the FSP Aurum Pro 1000W is priced decently and performs just the same, there isn't anything that really makes it stand out amongst the crowd. That always seems to be a problem in the power supply market. It is very saturated with the good, the bad, the ugly, and everything in between. Being just another unit isn't enough these days, especially when it feels like just another unit from the same company.
