Loading up a UPS - any criteria?

[carbon8ed]

Managed to bag a Dell 1500VA USB 230v for a very good price.

Still in APC warranty and with the main rig running 4 x SETI is indicating 33% on the little LED things on the front.

When I turn SETI off, it drops to using just 16% as draw. Have decided am gonna also plug my E6600 into it - well just because I can LOL.

Question, I am using 2/5 indicator lights on the power draw (33%) running just the main rig - no monitor. Is there a formula for calculating how many rigs I can attach before the UPS will not be any use to shut the machines down etc?

Cheers

For such a formula to be of any use you'd have to know the exact power draw of each of your rigs. This number is not equal to the power rating of the PSU.

thought so - im surprised at how little draw the main rig actually takes - got the 1500va version as watts to va conversion suggested this was the one i would need
