EMI Results - Average Detector
The PSU's EMI filter failed in this test, as evidenced by the increased noise at lower frequencies.
EMI Results - Peak Detector
There are a notable number of spikes in the Peak Detector test, though none of them exceed its limits.

richardvday I am very curious why so many 1000W or larger PSU's ? How many of these do they actually sell ? How many people need a 1000w PSU ? 500-600W seems the sweet spot that most people would need. I have an 850W that I have been kicking myself in the head for ever since really. I need 500W so my efficiency sucks, wasting energy.Reply -
totalinsanity4 PSUs are actually most efficient when you're at about half load, so people with 500-600W loads will actually be seeing a slightly lower power bill with a 1000W PSU than, for instance, a 650W oneReply -
crmaris modern PSUs featuring LLC resonant converters also have good efficiency under light loads regardless capacity, given that their design is good. With LLC Burst Mode efficiency under light loads vastly improves.Reply
