  • 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?

    lahat ng 3 computers ko dito sa bahay na ka UPS. 1x apc (low end) 2x ab;erex 600va(2008 pa gamit ko). wala pa naman nasisira sa mga computers ko.. yung isang unit nga ay 24/7 since 2009...

    after 2-3 years UPS battery pinapalitan ko hindi psu.. :)

    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
  • pwede po ba isaksak ung extention cord sa UPS?
  • @TS

    pag UPS ka, expect medyo mahal but i never encounter issues sa UPS. Yung mga computer shops sa mall, they usually sell good UPS regardless of cheaper or expensive brand.

    But you need to get these on a UPS so kung wala, wag mo bilihin.

    FF:
    Get the one with OV / UV protection and Surge protection.


    Just make sure your UPS is greater watts compare to your PSU if may kakabitin kapa iba.

    Kahit nga yun brand na Elite, it saves me a lot of times during black out. Better than AVR.

    kung mag AVR ka, get the Secure brand, request mo na lang kung may 1000w or more para hindi sagad yan sa psu mo 850w.

    @lorin

    yup, just make sure it doesn't go over the watts the ups can provide otherwise goodluck.

    @polka

    Those are extreme rare case. its like saying may isa tao dyan nasira ang seasonic then sasabihin pangit ang seasonic brand.

    ang importante kc sa ups dapat may buffer ka ng 200w para hindi na sasagad.
    sinewave or not, pag na sasagad kc ang wattage, there is a chance talaga na dadale yan ups.

    sir ito po kayang UPS na to? balak ko lang isakisak dyan ung PC ko na vs450 psu, monitor, tas router ng internet at paminsan minsan ps4. eto po balak ko bilhin na UPS APC Back-UPS BX650LI-MS 650va / 325 Watts UPS ok na kaya to? bihira lang naman mag brownout dito samin pag malakas lang talaga ang kulog at ulan
  • @lorin

    no, too low yan. pwde pumutok fuse mo dhl dyan.

    get 1000va/700w. meron yan sa mga computer shops. may mga model na around 3-4k or 4-6k.

    make sure to test the unit sa comp shop store before e uwi. pwde kc may mga naka tambak na dead battery.

    also make sure its not old model.

  • @KiraValentine32
    mahal pala sir. ano po ba maganda ung mura mura lang sana ung nasa 2k to 3k lang ung range. surge protector po kaya ng omni ok na?
  • @lorin

    gamit ko dati "Elite" brand then nagpalit ako to "Secure" na brand.

    both ok naman. Yung iba sabi din ok yun FSP na brand. nasa 4k un i think.

    APC is a well known brand kaso sobra naman mahal.

    these are UPS ha, not AVR.

    ok din naman kahit wala OV / UV, yun nga lang e pag nag OV / UV na nasira either ups or psu. wala sisihan un but it is still way better than direct plugging into wall.
  • @KiraValentine32
    pero ung surge protector sir na nsa 800 ata na omni pwede na rin un?
  • @lorin

    parang AVR ata bibili mo?

    hindi kita mabigay ng number kung ano dapat kunin mo. Dapat check mo yun iba kakabitan mo sa UPS / AVR. Tignan mo sa back ng monitor mo sticker kung alin watts consume + psu + iba kakabitan. kung sabihin natin ang total is 800w, kailangan 1000w un AVR/UPS. kahit extension cord pa yan hindi pwde e sagad ng appliances.
  • @KiraValentine32
    ah cge sir salamat baka mag surge protector nalang po ako ung extention cord ng omni sabi nila maganda naman daw un. mahal kasi ng UPS eh
