Hi - i have recently bought a US Robotics 8000a 4 port router off Fleabay, and the power supply was missing so checked the required spec, and it needs a 5v 2amp supply.

I emailed the seller and he sent me a 5v 1 amp supply, but is this good enough ?

A friend has cobbled together a 5v 2 amp supply from a printer ( i think ) and had to do a bit of jiggery pokery with the connector, which wasnt the right type on his cobbled job. It was supposed to be a barrel type, but he sorted it ok. And its working - just looks ugly !

Now, what on earth is in a router that requires such a big ampege ( 2 ) and can i use this 5v 1amp supply instead ?

I wasnt a happy bunny as the seller said this router was brand new, boxed, so why was the supply missing ? Still thats another story
 
does the router support Power Over Ethernet ?

that could cause it to draw lots of amps

either that or its not particularly efficient and is drawing more current than it needs.

have you actually tryed the 1a PSU ?

Hi - no i dont know if it does POE and i havent tried the 1 amp supply yet. Just came today, and i'm reluctant to whack it in yet. Just wanted to ask someone who has knowledge of these things, as i'm useless with this stuff.

I'll check the manual for POE.

Theres 1 main PC, and 3 connected to the router - thats really all i do with it.

NB have checked the manual, but its just the installation guide, so does not mention POE at all.

Just found this...

afaik you cant damage it by having an underpowered supply

it will simply fail to power on, or will just turn off, play up etc..

personally id be pestering the ebay seller for its proper PSU while your at it.
 
OK LOL - if i cant do any damage by under supplying, then its worth a shot.

Yes i emailed the seller when i got the router 3 or 4 days ago. I told him the PS was missing ( from a brand new boxed never used router ??? )

He said he would have a hunt around. I then told him it needs 2amp 5v. Today i get 1 amp 5v and the label on the PS clearly says its 1amp. Go figure

no i mean pester him for the right one, the 2amp one

hes obviously just grabbed one from anywhere to send you
 
Yeah i did pester him :)

I told him before he sent the 1amp that it requires a 2amp 5v PS. He still sent a 1amp 5v !

Never mind. I'll try the 1amp and see what happens, otherwise i'll have to hunt through all my leccy supplies and connectors and cobble something together with solder. :)
