  • AVR ka n alang.

    pwede din UPS yun nga lang make sure that true-sinewave yung UPS na gagamitin mo hindyo yung cheap UPS lang.entry level true-sincewave UPS cost around 20k+ for second hand. Yes were not joking, that's the price you need to pay for a PFC based PSU.
  • ..ay grabe.. ang mahal pala sir.. haha.. sa build ko po ba pwede ko gamitin ung 500w n avr ko khit 850w ung psu ko??
  • kung walang AC motor kahit di na pure sinewave na UPS,
    normally DC motor mga fan ng PC so ok lang. pili ka lang at least 1500VA na rating ng UPS
  • I think you're good with 650VA APC UPS. Di naman porket 850w ang PSU mo, yan na ang continuous usage nyan, 850w is just the peak your PSU can do.

    Pero given naman sa PC specs na binigay mo, I doubt your PSU wattage usage will go beyond 30--400w as long as yung PC mo lang ang nakaconnect without the monitor.

    400w is equals approximately ~500VA at peak usage. So 650VA APC UPS is still good.
  • ..ayun..maraming salamat po sir.. haha..
  • i warned you, wag ka iiyak pag pumutok yang PSU mo.

    if youre not convinced go ahead and ask the same question on seasonic PSU thread here in tpc, or just a simple gooogle will answer your questions.

    i repeat, any UPS that is not pure-sincewave will damage your PSU.

    As long as he has a good true-rated PSU with Active PFC (power factor correction), having a 'pure' sine-wave output from his UPS is much less important than having a power-backup.

    To OP: Make sure to buy decent UPS like APC, we're using it for a long time (650VA) and haven't encountered any damages due to non sinewave output like Polka mentioned.
  • wow, do you even know that PFC based transformer hates half ass sinewave ac?

    Exactly, I never had any bad PSU due to UPS. It is actually more questionable to suggest an AVR than a standard UPS. Unless of course if you have an ATS in your facility/room like I have here in office.

  • kung erratic ang kuryente mo may power spike na matindi bili ka ng totoong AVR, ung servo type, then kabitan mo ng UPS safe na safe na yan lalo na kung napaka mahal ng pc mo
