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 Lepa G1000-MA 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 rails, we see 2% across all rails. 12V1 faired the best with a total drop of .14V and 12V3 faired the worst with a total drop of .19V. The 5V rail managed to stay within 1% of specification with a total drop of .05V from start to finish. Moving towards the 3.3V rail, we see that regulation was again within 1% of specification with a total voltage drop of .05V.
DC Output quality for the Lepa G1000 was excellent 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 29mv on noise on the 12Vrail.
The Lepa G1000-MA 1000W is rated for 80 PLUS Gold efficiency. This means that the power supply must perform at 87%/89%/87% efficiency at 20%/50%/100% loads respectively. As you can see, the Lepa G1000 passed on our bench wasn't close to failing at any point.
The Lepa G1000-MA is the third Lepa branded unit that we've had come across our test bench to date. We have yet to be disappointed and we hope that as long as Lepa continues to use rebranded Enermax units that we aren't either. We aren't entirely sure where parent company ECOMASTER is going with the Lepa brand, but you can be sure that as long as they continue to utilize top notch power supplies from Enermax, they will soon be a name that rivals Antec, Thermaltake and more.
Considering that the Lepa G1000 is a house brand power supply, you simply couldn't ask for better performance out of a unit. Voltage regulation is within 2% on all of the 12V rails and within 1% on both minor rails. Many top tier manufacturers struggle with this level of regulation and here we have it from a house brand. DC output quality is just the same, showing a maximum of 29mV under full load. Topping things off on the performance, we see near Platinum levels of efficiency.
The top notch build quality of the unit contributes to the performance we see, including 100% Japanese capacitors throughout the unit. In fact, the only thing that we can't find top notch with the Lepa G1000 power supply is the warranty.
They know that the quality is there so it doesn't make much sense to lower the warranty period for the PSU. We are quite sure that this will dissuade a few potential customers who are unaware of the relationship between Lepa and Enermax, even if the unit is one of the cheapest compared to the competition.
