CalinTM Posted March 11, 2013 Share Posted March 11, 2013 I have a question about active PFC. My PSU is a AX760i, has active pfc.From what i know active pfc makes the power supply to work with different voltages, 110V/200V/230V/240V etc. I have a problem, i also have a UPS Mustek 1590 and if i power the PSU within UPS i get on corsair link software only 200V, instead of my normal 230V (Europe i live). Why is happening this ? Also, if i get only 200V the power supply could broke, or my PC hardware could suffer from this issue ? I imagine on US the power source has 110V, and people are using that voltage and i guess is nor harming the hardware, no ? And if i connect the PSU without the UPS i get 230V. On the AX760i says: Universal AC input from 90~264V So it works on 200V too, but i wonder a 230V isn't the perfect AC input ? Link to comment Share on other sites More sharing options...
Synthohol Posted March 11, 2013 Share Posted March 11, 2013 sounds like the UPS is throttling the voltage. how many AMPs does your outlet/circuit breaker/fuse provide with 230V? just curious. Link to comment Share on other sites More sharing options...
peanutz94 Posted March 12, 2013 Share Posted March 12, 2013 I don't think it's supplying enough voltage. If you look at the specs for the battery it says Backup time ( one PC load at 120 W ): 40 min. So if your system is pulling considerable more then that , it may potentially be the issue. I don't know much about the UPS so this is partially a guess! :) http://www.mustek.de/en/11/index.php/en/products/ups/ups-3/139-pm1590e/123-pm1590e It's also a simulated sine wave UPS and Corsair suggests only pure sine wave UPS with their PSU's. Don't know if that could be part of the issue or not. Also, if i get only 200V the power supply could broke, or my PC hardware could suffer from this issue ? There is always the possibility of data corruption with any power related issues. But your hardware should be fine . It would just refuse to run correctly if at all, but shouldn't be any damage. Overvoltage on the other hand.... Link to comment Share on other sites More sharing options...
CalinTM Posted March 12, 2013 Author Share Posted March 12, 2013 And then why in US works with 110V, mine could not work with 200V, then ? Link to comment Share on other sites More sharing options...
peanutz94 Posted March 12, 2013 Share Posted March 12, 2013 It should, but for what ever reason your UPS seems to be loosing 30v somewhere. So that would be a question for the maker of your UPS. Link to comment Share on other sites More sharing options...
CalinTM Posted March 12, 2013 Author Share Posted March 12, 2013 Grabbed a normal multimeter (not something fancy and expensive). On my main power source has 270V, and on the UPS outputs measured 230V. Then what should i trust ? Why the software says 200V, and the multimeter on UPS says 230V Link to comment Share on other sites More sharing options...
peanutz94 Posted March 12, 2013 Share Posted March 12, 2013 Hands down trust the meter. It's a known fact that software can't be trusted. Link to comment Share on other sites More sharing options...
Synthohol Posted March 12, 2013 Share Posted March 12, 2013 yup, meter all the way!!! Link to comment Share on other sites More sharing options...

It's losing not loosing. Since you like to correct my posts. :biggrin: Link to comment Share on other sites More sharing options...
