UPS for Seasonic X-650 with Active pfc

[snipershot]

Hi all,

Config:

CPU: i7-4790k
Cooler:h90
MOBO: Asus maximus vii ranger
Memory: ( 2x4gb ) 8gb ram
Primary HD: Samsung 120gb evo ssd
Secondary: 1tb wd black
Graphics Card: NA
PSU: Seasonic X-650


A gtx 970 will be added soon.

So, the psu load would be approximately 420 watts including the graphics card.

The situation is that according to some sources, the Seasonic PSU has a feature called Active PFC which works best with a UPS that supplies a pure sine wave. I have read in a few forums that a UPS which provides stepped approximation to sine wave would work if we use a high VA rating UPS like 1000VA or more.

According to seasonic the UPS must be at least 50-100% more capacity that the actual wattage or power draw.

I need to get a UPS which will give me about 5 minutes time to shutdown the rig.

Can I use my existing UPS or do I need another UPS. Would a stepped sine wave 1000va be sufficient?

Thanks

If anyone here is using a seasonic psu, please do post what type of UPS your computer is running on. Has anyone used a quasi wave or stepped approximate sine wave UPS with such a PSU?



I checked pure sine wave inverters but they are a bit expensive than the others and I have limited budget for a UPS. I have checked with vguard and Hykon and they are quoting UPS above 12k. Please let me know what type of UPS would suffice my rig as I just need about 5 mins time to power off my rig. Thanks in advance

Bump..anyone?

Apc 1100va ups should do the job.

Installed seasonic s12g 750w psu in my rig yesterday. I have numeric digital 1000 plus-v ups. Seems to be working fine. Can't say yet whether it will sustain heavy load when it runs on battery. U r better off going with APC ups suggested by this forum members I guess.

Being a simulated sinewave iBall nirantar 1kva, there's no prob with my system since 10 months. Backup time - with gaming (300-350W load)-> 4-5 minutes, without gaming (100-115W load), it gives 30 min backup. Pure sinewave of apc1100va would be better though.

apc1100va is approximated sinewave...
your PSU's will buzz on battery power doe to bad waveform
on sinewave ups'es no buzzing and absolutely silent(like mine)

Hey there, during a power outage, when your UPS starts to work, do you hear any clicking sound from the PSU?

Thanks for the reply!

[MENTION=138043]kARTechnology[/MENTION], In your signature you have mentioned that you currently do not have a UPS. Are you running your PC from a home UPS + Inverter which provides a pure sine wave? If that is the case, is it safe to run the PC from a HOME UPS+inverter which provides pure sine wave by switching it to UPS mode?

Also, regarding the buzzing sound, is it really bad to get that sound for the PSU. Is the clicking sound a counter mechanism to adjust to the approximate sine waveform ? Is it bad for the capacitors?

Waiting your reply. Thanks m8!

[MENTION=85778]smltngs[/MENTION], I did check the numeric 1000 plus-v UPS, could you please specify your PSU model. And is there is any buzzing sound from the PSU as [MENTION=138043]kARTechnology[/MENTION] stated.

Thanks for your reply!

Go with APC like the experts suggested. Tiny buzz was there in battery mode not clicking sound. Seasonic s12g 750 PSU, only installed yesterday. I was able to play a game for few min but sometimes cold start is an issue with this ups. It might be the battery or old electrical wiring in my house. APC might be few k costlier but many here suggest it. Go with APC don't compromise.

i'm directly using pure sinewave inverter in ups mode...amaron 800va+ many other loads(lcd tv, HT pioneer, lights and fans)
absolutely silent/no sound in battery mode

where have you been man? seeing you after a long time :O

 

[ashis_lakra]

I just checked my UPS on battery and after close observation, i couldn't hear any humming noise apart from the fan spinning. So, it doesn't bother me much.

Busy with job and missing my favorite PC

ohh, you're doing a job now? thats great to hear man. i miss you rig suggestions here

 

[rijinpk1]

^^ I will come back
@op, if you already have an inverter with pure sine wave output, you can safely turn on UPS mode on. Some inverters are square wave type. So check it.
Apc UPS is generally suggested here and used by most people with high end configs. If you are short on budget, apc will do the job fine.

Thanks mate. How much backup time do you get and how many watts does your rig pull?

under normal browsing 3-4 hrs i think... never measured as sometimes i switch off other loads[except lights(28w)x3]
sometimes when it stops(low battery)and after i turn off pc's switch, it automatically resumes from the remaining battery left until that also drains fully...nice and intelligent inverter
