Need help on UPS selection

  • Hi guys, need your help. I need a UPS just to properly shutdown the computer during power outages.

    How many watts and VA of UPS do I need for this pc:

    Amd Ryzen 7 2700x

    Gigabyte GA-X470-Aorus-Ultra Gaming

    G.Skill Trident Z RGB 64GB

    Zotac GTX 1070 Ti Mini 8GB GDDR5 256bit

    samsung 970 evo m.2 nvme 250gb

    2pcs Samsung 250gb SSD

    Seagate 2TB HDD

    Seasonic Focus+ 750PX 750watts 80+ Platinum full modular

    6pcs 120mm fans

    23" Asus ProArt 238Q Monitor

    Thanks in advance.
  • buy a wattmeter on shopee or lazada, if you want a cheap that works, a omni wattmeter works just fine.

    put your PC in worst case scenario, eg run a game benchmarking tool, let the benchmark finish and check your meter what is the max wattage.

    once you get that you can just multiply you wattage by 2 and you get your VA rating that you need for your UPS, of course UPS manufacturer recommend always have at least twice the required VA so multiply by 2 again.

    theres also a golden requirement today that you also need a puresine wave ups, but the newer models of UPS that uses simulated sinewave works just fine, I think..... but some people still having issues with their UPS killing their computer's PSU (mainly due to PSU transformer failure due to square-wave power source).

    for gaming recommended UPS is puresinewave UPS just to avoid your PSU going kaput during brownouts while gaming
    the cheap simulated sinewave UPS works just fine for everything else like office pc, printers (except laser printers), etc...
  • your using a Seasonic PSU that likes pure sinewave UPS eto ang PSU na usually namamatay sa cheap simulated sinewave UPS
  • ^well not just cheap even a reputable brands like APC na old models UPS can also kill it, to be honest the cheap UPS have the same quality/functionality ng older model APC UPS.

    so yeah, just check the APC website and go familiarized your self for their newer UPS lineups. Tapos sabay gamitin mo na yan as reference and search it here in TPC or Lazada/Shopee (both have official APC stores on them).

    recommended lineups ko sa APC is either BACK-UPS PRO or SMART-UPS. If you have money with SMART-UPS lineup, go with that, else BACK-UPS PRO will do just fine.

  • Here's my experience with APC UPSes. I currently use 5 with varying capacities and uses (BX625CI-MS, BX800LI-MS, BX1100LI-MS hooked to desktops, routers, modems, TV's, and PS4's). All are Simulated Sine Wave. APC calls it stepped approximation to a sine wave. Napakamahal ng pure sine wave UPS.

    Current specs on an APC Back UPS BX1100LI-MS, 1100VA / 550W:

    CPU: Intel Core i5 4670K
    COOLER: CM Hyper 212X
    MOBO: Asrock Z87 Extreme4
    RAM: 4 x 4GB DDR3 2133MHz G.Skill
    GPU: Zotac GTX 1080 AMP Extreme
    SSD: 1 x 120GB Sandisk
    SSD: 1 x 500GB Samsung 850 EVO
    HDD: 1 x 2TB Seagate Firecuda
    HDD: 2 x 4TB Seagate Firecuda
    PSU: Enermax Revolution87+ 850W
    CASE FAN: 3 x 230mm, 1 x 140mm
    MONITOR: Gigabyte Aorus AD27QD, 27-inch

    > up to 2 minutes uptime while playing a game; have not tested beyond that
    > PSU is 9 years old and counting; plugged in to UPS only last year, January 2018
    > UPS is 1 year old so far

    I also have 3 Seasonic PSU's: M12II EVO 520, 620, and an old 350W 80+ Bronze hooked to an APC BX800LI-MS, 800VA / 415W.

    Naka-experience na ng catastrophic power failure. Pattern was: power off - power on after 1 second - power off. Happened at least twice over a period of one day. Naka-experience na rin ng sunog just a couple of houses away. UPSes were flickering, i.e., switching from clicking sound to no-power-beep repeatedly.

    6 days after the power failure I mentioned, namatay ang isang Seasonic M12II EVO 520. It was 4 years old, and plugged in to a BX800LI-MS for just 3-4 months. Buti nalang may 5-year warranty, so I was able to claim it from Helix Tech. They gave me an M12II EVO 620 PSU as a replacement.

    Nakapag-claim na rin ako ng warranty for APC BX625CI-MS. It went crazy after a year of use. I called their 1-800 hotline to process the RMA. A truck went to our house a few days later to give the replacement. Binigay ko rin ang defective unit sa kanila.

    All my PSU's are good so far. May mga regular power failures pa rin due to scheduled maintenance, but nothing as dirty as the previous ones I mentioned.

    I get my wattage estimate from here:

    At the end of the month, mag-upgrade na ako to an i9-9900K system, and I'll be using the same UPS. Estimated load wattage, including components that I'll add in the future: 525W.

    Upgraded Specs:
    CPU: Intel Core i9 9900K
    COOLER: Corsair H115i RGB Platinum
    MOBO: Gigabyte Z390 Aorus Master
    RAM: 2 x 8GB DDR4 3200MHz CL16 Aorus RGB
    RAM: 2 x 8GB DDR4 3200MHz CL16 Aorus RGB (future)
    GPU: Zotac GTX 1080 AMP Extreme
    SSD: 1 x 512GB Aorus M.2 NVMe
    SSD: 1 x 1TB Adata XPG SX8200 M.2 NVMe (future)
    SSD: 1 x 500GB Samsung 850 EVO SATA
    HDD: 1 x 2TB Seagate Firecuda
    HDD: 2 x 4TB Seagate Ironwolf
    PSU: Corsair RM850x, 850W
    CASE FAN: 3 x Deepcool CF120 120mm, 2 x Deepcool CF140 140mm
    LED: Deepcool RGB 200 Pro LED strips
    MONITOR: Gigabyte Aorus AD27QD, 27-inch

    I am currently looking at an APC Easy UPS BV1000I-MS 1000VA / 600W to replace my BX1100LI-MS. However, load goes up to 598W if I plan on upgrading my GPU to an RTX 2080 Ti later on. Kung mag-upgrade man ako ng GPU that's similar to the power draw of an RTX 2080 Ti, mas may allowance ang APC BX1400U-MS 1400VA / 700W. Mas mahal rin siya by about P4,000.
  • well I dont really recommend power calculator as much as possible, the offset between the calculated power vs the actual power consumption is way off, sometime +70-120watts diff.
  • Thank you for all the input guys. Unfortunately don't have a budget for those expensive pure sinewave units.

    Will this suffice?

    Product details of APC BX1100LI-MS 1100VA UPS:

    Output Power Capacity: 550 Watts/1100 VA
    Max Configurable Power: 550 Watts/1100 VA
    Nominal Output Voltage: 230V
    Output Connections:(2) IEC 320 C13 (Battery Backup) (4) Universal Receptacle (Battery Backup)
    Nominal Input Voltage: 230V
  • Ano brand ng ups na ok maliban sa APC? MEdyo pricey kasi yung 1000V ng APC. Meron akong nakita, Secure, AWP at Aberlrex na pasok sa budget ko. Ok ba silang brand?
  • ^^^ UP

    Looking for UPS recommendation
  • ^ look for the 2nd post on this thread to choose for the proper UPS capacity model.

    for brand recommendation, always APC.
  • ^ I stumble on this thread also, kasi nag hahanap din ako ng bagong UPS, so far APC talaga maganda, pero may one time na din pumalpak yung APC sa akin pero that was 2011 pa at naka x5 replacement ako until na ubos yung store warranty ko.

    I've tried INTEX at SECURE pero halos 6months to a year lang sira na. Nag rarattle pa if mag battery power sya, kakatakot.

    As per experience okay parin yung APC, kahit mahal sya. May mga nakita ako like AWP which is cheaper pero sa mukha palang ng UPS, halos same2 lang sila ng INTEX at SECURE, na trauma na ako sa mga brand na yun.
  • recently bought BX1100LI-MS. Lasted only a week and it failed after the 4th power outage (yup ganon ka dalas power outage sa amin). Using a Seasonic M12II 620w and they are replacing the UPS. Im worried baka di talaga compatible and might happen again soon. Any advice? Should I go for the pure sine wave models (costs way more expensive)
  • ^Sir san mo nabili yan and magkano? More than 3 yrs na itong APC Back-UPS 950VA ok p rin, at least twice a week nwwla kuryente. Kung money is not a problem, mag online UPS ka na lang, but that costs an arm and a leg haha
  • sa shopee yun eh since I love PC atbp. Pero had my unit claim warranty sa APC na mismo. Baka minalas lng talaga ako sa unit? Ano po pala PSU mo ive read somewhere maarte dind aw seasonic PSU sa UPS. Nakaka praning yung nangyari talaga.
  • I'm using Corsair HX850i PSU, no problems so far kahit na mas mataas wattage haha, pero mababa naman actual power draw ko @400W+ at full load. Good that you got the warranty claim sa APC sana makuha mo agad. Malas lang siguro sir.
  • Kung money is not a problem, mag online UPS ka na lang, but that costs an arm and a leg haha

    yeah online UPS is probably the most expensive type of UPS you can buy out there but its worth it naman in terms of all protections it can give to you, specially on a electrical environment where power fluctuations is a norm. plus its also a pure-sinewave inverter inside which is good for all type of appliance you can plug to it (at least to an extent of wattage).
