I have multiple APC UPSs which all output a "stepped approximation to a sine wave" when on battery power and the specs on my newest at least state up to an 8ms transfer time from line-power to battery-power.
I've had trouble with my Antec Earthwatts 500 PSU from day one. Typically a dip in power (rather than a full on outage) will cause my entire machine to immediately reboot. I've only recently realized this PSU/UPS combination is the culprit.
I believe that it is either the transfer time or the stepped sine wave approximation or both that are not mixing well. Some reviews blame it on the Active PCF, and others implied that the transfer time may be longer than the PSU will accept. In my older UPS many dips in power would cause a reset event. in my brand new UPS any dip will reset, and pulling the plug will reset but not allow it to reboot.
Since my UPSs represent the larger monetary investment and are newer, I figured I will replace the PSU to get one that is compatible. I've been researching and been unable to find any sort or metric to determine a brand or model that will work. Short of buying and returning until I find the right combo, I thought I'd ask.
I have the APC Back-UPS Pro 1000, APC Back-UPS XS 1500, and APC Back-UPS XS 1000. What kind of PSU should I be buying? I would love features like "silent", "efficient" or "powerful" but at this point I'd settle for "works", "doesn't burst into flames" and "doesn't cost an arm & a leg".
