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 Thermaltake EVO Blue 2.0 850W 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 .19V. The 5V rail managed to stay within 2% of specification with a total drop of .09V 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 .07V.
DC Output quality for the Thermaltake EVO Blue 2.0 850W was good and well within specifications. During Test 1, we saw 19mV of noise on our scope. When we increased the loads in Test 3, the ripple climbed to 27mV at around half load. During Test 5 under a load of 850W, the oscilloscope showed a maximum of 38mV on noise on the 12V rail.
The Thermaltake EVO Blue 2.0 850W 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 EVO Blue 2.0 850W passed on our bench, and wasn't close to failing at any point.
The 750W to 850W power supply market is perhaps one of the most crowded segments for a power supply to compete in. As such, it is hard for a power supply to stand out from the crowd, as there is almost certainly something already on the market that does what you're trying to do. That means you either have to do it better, cheaper, or both to make your unit more than "just another power supply".
That is exactly the problem with the EVO Blue 850W power supply. Starting with price, it is sitting right in the middle of the pack, so it can't quickly pull ahead there. As far as build quality and performance is concerned, they are both great. Unfortunately (for Thermaltake), I can still point you to power supplies in the same market segment that have the same build quality and performance, but do it for less money. Some of them even have better performance and efficiency.
What that leaves the EVO Blue 2.0 850W power supply with to stand out are aesthetics. It isn't much considering the nature of power supplies, but there are times when it is important. As the EVO Blue 2.0 features an LED fan, it is obviously meant to be seen and when you add in the color choice of the unit it does help make the unit stand out a bit. That is the key to the success of the EVO Blue 2.0.
It has the aesthetic edge over the competition while still performing well at a decent cost. It is one of a handful of units with an LED fan in the 850W market that I could find.
