Hi there.

I want to know what ups do you guys recommend for a small office (well not that small) here is what we going to power from it.

1. Fridge
2. Microwave
4. 2x small nas devices
5. 1x i7-2600 pc with 3 screens 2x hd6670 graphics cards (80+ psu)
6. 1x i7-930 pc with 2 screens amd hd6650 graphics card (80+ psu)
7. 2x simple i3-2100 with onboard graphics and 1x screens
8. Server room consumes about 500w
9. 3x laptop. 2x plain dual core laptops and one sandy bridge celeron laptop
10. projector (samsung)
11. fax machine
12. toaster
13. security camera
14. 2x printer (Samsung clx-6220fx and HP 1022nw)
15. Mypbx telephone system
16. ice maker (whatever you call them)

The reason for asking as we currently moved office and don't have proper ups equipment here yet. in the old office we use to power the pc's, Laptops, Printers, fax and security camera with a mecer 10KVA ups and everything worked out fine. I'm scared that the 10KVA ups is not going to be enough to carry the load and keeps on tripping.

Currently we work in this way. only the servers protected by 3KVA online ups. So please suggest a cheaper solution for me if the 10kva ups will not be enough.

before anyone think I'm stupid due to the circuit board layout we can't really split the kitchen from the rest of the office. So please don't troll :D

Thanks
Nelis

How deep are your pockets?

It'd probably cheaper buying small individual UPS's for the equipment then trying to run a fridge and a microwave off a UPS
 
well deep enough. Don't worry about money just not something that's R100K :D do you think I should get a pure sinewave ups for all the pc's or will modified sinewave also be fine. i'm scared modified sinewave ups will break a pc cause the i3 pc's are just running like a simple oem psu. I can maybe get away with a 1KV ups for each pc. just enough to quickly save an shutdown pc. shouldn't take longer than 5min.

Last resort should be some new big psu over 10kva. just another question. do you think that 10kva ups will handle everything? I mean I won't use everything at the same time.
 
You want to put a toaster on a UPS?!? You mad bru.

Some for printers and fridge (though slightly less so).

Well if we get a big ups that we need to connect to the circuit board we need to have the toasters etc etc on the ups aswell. we will not be using it while we on battery. but right now getting a ups for each pc sound like the only option. what do you guys suggest for best reliability while keeping it as cheap as possible?

No you don't. Even if you get a big UPS, the toaster will wipe out the charge & depending on size maybe kill it. And yes the tea lady will make toast during a blackout even though you told her not to.

Do the sane thing and put the kitchen on a separate circuit (Toaster and fridge).

Printer is kinda dicey too.

Also, dedicated UPS plugs plugs. Usually blue ones iirc. People will still manage to jam a kettle into your UPS circuit though...brute force. One of my dads client's nearly lost a UPS worth a couple hundred k that way.
 
I know about ups plugs. Shoul I wait for electrician to come and split the kitchen from the other plugs?

I'd really play it carefully tbh. Like I said you can really fry the UPS & insurance is going to laugh at you...

Red plugs :) shaved earth pin.

No red is dedicated. Meaning normal grid, with a breaker but no earth leakage. UPS is generally another colour blue I think. Also shaved earth point, but different angle.

Someone posted a listing of the most common colour usages, but aside from the red none of the designated colours are really consistently used.
 
Every place I've ever worked has used red for clean/ups power.

Correct... and asks for professional installation. Also consider taking out laser printers from the circuit, substitute by backup inkjets.

Blue is UPS. Its not regulated though, so technically red is acceptable too. Red could be UPS or not depending on what the electricians (&build specs) felt like, blue is 90% certain to be UPS.

The red ones are much easier to obtain so some electricians go for red on UPS powered plugs too. Its been discussed here:
