If you were gaming, it will consume about 80%
Problem is, I have 5A for the entire house and as soon as the electricity drops and the generator turns on (sorry for the next term, i don't know the meaning in english) the "Disjoncteur" splits.
Now if i knew how much the UPS drains from the electricity, I could take some measures in terms of getting a timer for other devices so the split wouldnt heat up the "Disjoncteur" instantly.
Circuit Breaker ! :)
well since watts = amps x volts(220) , and the maximum you 1.1kva UPS could probably provide is 800w (but im sure it drains less as per usage 500ish max- ) then 3.6 amps in theoretical full (max) load - probably 2.x amps under normal use.
Im no electrician, but going by theory - hopefully a more experienced electrician can confirm
Cheers

2.x is "OK" but 3.6 is way too much!
Thanks Rubz.

i'm going to order this: MGE Eaton Nova 1250VA UPS and hopefully i can sleep in a flame free environment
thanks for the help

I really recommend getting an 1400VA, would be better for your 800watt psu.
1200VA = 720 Watt
1400VA = 840 Watt
exhaler
that's odd because according to
this 1250VA = 812.5 Watt and 1400VA = 910 Watt
After some researching on the MGE website, 1250VA = 660 Watt and 1400VA = 800 Watt
i got those numbers from the manual of each UPS

It depends on the power factor.
The PF in the PCE UPS systems is 0.6. Watts = VA*PF -> 1200 * 0.6 = 720
1400 * 0.6 = 840
PF is the ratio between the amount of dissipated power and the amount of absorbed power
its determined by True power/apparent power (in watts)
other UPS's state the power factor as 0.7 for example

I'll take your advice then and get the 1400VA
Rubz
Even though your psu is 800w, your consumption is barely 500w at peak - you dont need a 1400va UPS
But then again, if you can afford to splurge, then why not - youll just have more backup time
Good luck

I've ordered the 1400VA should arrive tomorrow, (@Rubz i can't afford to splurge, but i can beg for a raise :p)
anyways if you don't hear from me either i'm up in flames :( or on a mass effect 3 marathon :D
UPDATE
i just unpacked and plugged it in; all is well so far :D
The only downside is that it has a fan at the back and its like sitting next to a vacuum cleaner, maybe i should dismantle the UPS and unplug the fan :D
exhaler
UPDATE 2:
i've tried unplugging the fan cable but it has a sensor on the board and the UPS won't work :(
but i did figure out that i can slow the fan by pushing on it....or maybe i just leave it as it is?!
Rubz
Put under water. you wont hear a thing..or you could have bought the SMALLER one. with smaller power output, less heat, and a smaller fan..and less noise ! ha! but no!
dont mess with the fan man, keep it well ventilated or you are just asking for another flameball - just get a longer power cable and move it away from you
mine sounds like a toilet fan too, but i just got used it..besides..i do not hear it when i'm gaming
edit: and "mabruk" btw.
exhaler
Hahaha good point Rubz.....I never thought that the fan would make such noise, I'll just have to live with it
Thanks all for the help

Fans are essential, they cool the aluminum heat-syncs attached to the MOSFETS. Without a fan cooling them they will break in less than a month of heavy use.
My UPS has a fan too and its noisy but i learned to live with it, especially if i want to protect my rig and all the other gear running around.

Not that this helps, but i bought a 1000va invo UPS from Microcity
Best 60$ i ever spent - i had my doubts but its by far one of the best cheap UPS's i've dealt with.
Anyway yeah the bigger the more sound they would have, its only natural; my cousin though has this pretty hefty PCE one, he has 2 rigs running on it, and its quite silent, wish i saw this thread earlier would have suggested it (it cost only like 150$ if i recall correctly)
Anyway it's a good purchase, honestly better safe than sorry.

i was able to reduce the fan's noise by applying a small amount of silicon layer around the fan's borders where it is screwed to the case, acts like a cushion :D

How big is the fan? If it's 80, 92, 100, 120, or 140mm then you could replace the fan with a proper case fan and control that. I am betting that the simple heatsinks could easily be cooled with less rpm, and have almost the same temperatures, or a bit higher. At the very least, a quality fan running at the same rpm as a cheaper one, could be more silent, especially if the default fan is ball bearing and the replacement fan is fluid or sleeve bearing. Most case fans are sleeve bearing, which are of lower quality than fluid, but they last long enough I guess. Is the fan oriented vertically, or horizontally?

lol just make sure whatever you do with it, can be reversed/removed - just in case (god forbid) you need to return it for some reason under warranty-
Replacing the fan with a silent case fan seems like a good idea if it fits
exhaler
Thanks for the advise Rubz, in the mean time ill keep my eyes open for a silent fan
