DC Output Stability and Quality





The DC output of the 12V rail was as stable as Seasonic claimed in their promotional material. Total regulation was just above 2%, which is a very good result. The lower voltage rails don't do quite as well, with regulation of up to 5%. That's still within spec, but we have certainly seen better results. Given the importance of the 12V rail, however, doing well there means more than doing well on the smaller rails.





The ripple and noise measurements we measured were close to Seasonic's Chroma 8000 results. The 3.3V rail topped out at 25mV, much more than the 5V rail that stayed under 13mV. 12V1 also has very low ripple with only 16mV, but the second 12V rail tops out at up to 35mV due to a large spike.

    I have no idea... I think I said "and they feature" perhaps? Heh. Go Dragon!

    Argh! The fingers, use them! :) It's probably faster, too, after correcting two dozen mis-transcribes.

    I would... but carpal tunnel issues make it a problem.

    Sorry to hear about your carpal tunnel issues.

    But I have always thought that such issues stems from mouse usage. So at work I use my left hand for moving the pointer, and at home the right hand.

    Using a keyboard should not normally be much cause for concern?

    Blame the editor (me) and my speech-recognition. Should have been "fails".

    On page 3, about the cables, the speech-recognition software seems to have made another error

    [/quote]Most of the cables are detachable and come in an extra bag Seasonic provides. The 24-pin ATX connector, 4-pin ATX12V and 8-pin EPS12V connectors, 260cm 6-pin PEG connectors...[/quote]

    I think that should read two 60cm 6-pin PEG connectors.

    I thought someone was supposed to proof-read these. ;)

    What speech recognition s/w do you use Jarred? Do you use it just for large amounts of text entry or is useful for other things like quick posts like this. Does it make things quicker? Or does fixing the errors eat up a lot of time? I guess you just save time and don't fix those errors. haha j/k!

    Oh. U use Dragon. Well, other questions stand!
