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 Kingwin LZG-1000, we can test it to the maximum.
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 throughout all the tests. The 5V rail didn't quite fair as well with 3% voltage regulation and a total drop of .14V. Moving towards the 3.3V rail, we go back up to 2% regulation with a total voltage drop of .05V.
DC output quality was exceptional 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 measly 9mV 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 16mV. Under full load, we still only see a tiny ripple of 28mV. It's hard to get any better than that.
The Kingwin LZG-1000 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 LZG-1000 managed to do just that on our test bench. It was certainly cutting it close at all three points, but a pass is a pass no matter how close it is.
Kingwin made a great choice going with Super Flower for a majority of their power supply needs. The LZG-1000 is yet another fine power supply from Kingwin. The unit performed very well throughout all the tests we threw at it. The voltage regulation and DC output quality were exactly what you would expect from a power supply of this caliber and price.
Add in the ability to power a trio of graphics cards with 80Plus Gold efficiency and you've got yourself a hell of a unit that is only short a few features of being perfect. The only real shortcoming of the unit is the short 3-year warranty offered.
