Ripple & Noise

There are no significant overshoots visible in the graphs. The fundamental oscillation is minor as well, which means very low ripple & noise. In addition the voltage always regulates itself around the same value. +5V reaches 10-25 mV at 100% to 110% load in our tests. The result at +3.3V is just marginally higher. 70 mV on the stressed +12V rail is just above 50% of the allowed tolerance. Here we have shown the worst case and the measurements are representative, so the results are fine. During all of the tests the oscilloscope showed no noticeable transients of the voltage.

    power consumption of 0.25A. Reply

    Ok, its current drawn . Txs for pointing it out. Reply

    I've seen worst. For example, "The current's power is 220V." :-) Reply

    Ok, everyone who reads Anandtech and can use one of these 380W PSUs in any of your current or future rigs please raise your hand. anyone? hello? (crickets) anybody?

    Who thought it wise to waste their time reviewing this? I won't even read it.

    I have a Core i7 CPU, 12GB of memory, six hard drives, three SSDs, and two video cards with a 300W power supply. Reply

    I enjoyed the review, especially its technical component layout. It's nice to see Antec is making quality affordable, unlike PCP&C which makes quality unaffordable :) Reply

    I think you'd be surprised at the number of people using this size of power supply or even smaller. A lot of people even run dinky Pico power supplies. I have a couple rigs using 330W Seasonics, but I should be using even smaller supplies. I don't play ANY video games onboard video is fine for media server, or computers that crunch data.

    If I have a media server with a i3 530 that draws 35W idle and 100W load, I'd want a small power supply to make it run in the 80% efficiency range if possible. I'm looking to build a new one and am going to read the article. Even if it is not the power supply I want, I might still learn something.

    The only system you should need a > 380W PSU in is your gaming rig. Since you can't play games on more than one system at a time, the rest of your systems won't need it unless you're a quite extreme overclocker. Reply

    I appreciate this review. I build a lot of basic PCs for friends and family that don't need what I have. Reply
