Our old network admin bought the top range UPS a few months ago but never came around to setting it up and is no longer with the company. Now the old UPS broke down and needs to be replaced, but an external company that did an audit said that that UPS won't work.
Now we are no hardware specialists, but the difference in specs is a higher output from 5A to 8.8A meaning a higher output. But isn't the UPS supposed to give the server the required output anyway?
This 'independent' audit does sell its own hardware including UPSes so I'm not sure how much bias they have. Is there a reason why we can't replace the old broken UPS with the new more powerful one? Is there a way we can check to see if the UPS works with our server?
ok, i wrote down the numbers again, the Volts and Amps are what are on the back (where you connect up the plugs which seem diffrent from on the front label.)
old one
APC SmartUPS 1500 220-240V -- 6.8A
new one
Dell UPS 1920W 250V -- 10A
No--the computer(s) aren't going to draw any more power than they actually use. You could hook them up directly to a 120V 400A power source and they'd run just fine without burning any fuses--unless you have a short in the wiring or inside the computer downstream from the fuse. – Craig – 2015-06-05T05:16:04.200
note that watts = amps x volts. Most computer power supplies (in the US) will be 120v, so best case without considering efficiency, the 8.5A is going to put out approx. 1000watts. This would be the maximum wattage based upon equipment you can plug into the UPS (such as 20 50watt light bulbs) – horatio – 2012-04-04T14:00:41.403

-1, this belongs to skeptics.stackexchange.com. [/irony] Seriously, I thought this would be some conspiracy against UPS

1Great analogy: Electronic devices all have resistance. You can't force more current through, it draws a finite amount (based on the voltage divided by resistance). Raise the resistance, lower the current. Raise the voltage, raise the current. (and no, the resistance is not always constant) – Breakthrough – 2012-04-05T00:09:31.160
I'm not certain about this, but wouldn't the new one blow your fuses on a full load if you have 7-9A fuses? On the other hand, 6A to 10A is the standard gap in my country, so I don't know if such fuses exist. – onik – 2012-04-05T09:18:42.357
