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 lower than that of the SilverStone Strider Gold 1200W, we will only be able to test it to 1000W.
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. The 12V rail showed a total drop of .18V from start to finish. The 5V rail didn't quite fair as well as it only managed to stay within 4% of specification with a total drop of .20V from start to finish. Moving towards the 3.3V rail, we see that regulation was back within 2% with a total voltage drop of .06V.
DC output quality was close to what we expected from the unit. Our past experiences with SilverStone PSU's have shown this is one of their weakest points. While they are always very far from falling out of specification, they are far from being leaders of the pack here as well.
We started off seeing 23mV of ripple on the 12V rail during Test 1. As we increased the loads, the ripple had increased to 34mV at just under half load. By the time we had the maximum 1000W allowed by our test equipment, we were seeing 54mV of noise.
The Strider Gold Evolution 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 Strider Gold Evolution passed on our bench. Things were a little close at 50% load, but was a pass nonetheless.
The SilverStone Strider Gold Evolution is good power supply in many aspects. It performs well all the way around although not fantastic in any one particular category. SilverStone promised us from the start that this unit would be "The golden standard for PSU performance, efficiency, and quality," so we were expecting gold from start to finish. The included fan filter and the top notch tech support started things off very well but it just wasn't enough to convince us this is the best all around power supply on the market.
The SilverStone Strider Gold 1200W is very good at everything it does but other products on the market are just as good. The Corsair AX1200 that we looked at a few months ago is an equal performer and in many cases costs less. The $229.99 price at Directron though is the spoiler though and puts the Strider Gold 1200W in a better price position. Still the DC output quality on the AX1200 is a bit better and so is the seven year warranty.
The SilverStone Strider Gold Evolution isn't all that revolutionary in this highly contested market, but it is SilverStone's attempt at closing the gap between themselves and the competition. The new $229.99 price point makes it attractive though and you wouldn't be disappointed with the purchase.
