The sample reaches just 78% efficiency at 10% load, but at all other loads it's above 80%. The peak efficiency on 230VAC is 87.58%. At higher loads it slightly decreases and 83-84% is reached at full load. These are common results. The power factor reaches between 0.858 and 0.964. If we switch to 115VAC, the power factor always stays above 0.900 with a maximum of 0.984.

    power consumption of 0.25A.

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

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

    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.

    Everyone who builds HTPC's raises hands and applies cluebats.

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

    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 :)

    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.

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