    Question Uninterruptable Power Supply (UPS)

    Hi all,

    I'm thinking of buying an Uninterruptable Power Supply for use with my home file server,
    I just saw a fairly cheap one on dabs.ie : http://www.dabs.ie/products/best-val...lver-742H.html

    The pc that'd be plugged into it has the following specs:

    Gigabyte GA-EG31M-S2
    Celeron e1500 undervolted to 0.9v & under clocked
    2gb ram
    Freenas as the OS
    1tb WD green hdd

    Do u think the above linked UPS would be ok for the above purpose?

    that ups would do what its meant to, run long enough for your pc to shut down.

    Re: Uninterruptable Power Supply (UPS)

    It does not have an impressive output wave form, though having buck and boost it is doing more than just its "off line" version type would give it recredit, as these are line-interactive features. A good power supply should be able to cope with a poor wave form without any problems, it is quite small so your probably get less 10 minutes run time with your system. As gonzo says its enough time for it to shut down. Even having a large battery isn't as great as you might think. People have retro fit car batteries to UPS to get more run time this also increase the charge time, so the system will take much longer to cope with an extended outage with another one... and they normally come in atleast pairs.

    Re: Uninterruptable Power Supply (UPS)

    yeh i have one hell of a ups in the loft that i managed to get free (new batteries as well), its capable of a 3000w load, online and can keep my rig, phone and heating running for at least 30 mins

    had to go in the loft due to noise.

    Re: Uninterruptable Power Supply (UPS)

    No.

    You need one with a pure sine wave output, not a stepped approximation. Get the industry standard: APC Smart-UPS - I have two 750va units myself. My workplace standardises on Smart-UPS kit too - we have two big 3-phase 40+ kVA units, and random ones dotted around various offices.

    Stepped approximation sine wave output UPSes won't work with some equipment. Google it for more info.

    Re: Uninterruptable Power Supply (UPS)

    Anyone know what the general name is for a UPS which can go in 5 1/4 drive bays

    like this http://www.beam-tech.com/093001/prd_...ternal_ups.htm

    Seems a lot more tidy to me, and actually makes use of a drive bay.
