Hi, @Avalonhaze 

 

I agree with Wb2001's opinion.

 

The 180W P/S was used in the 8xxx Elite USDT PC's with the optional MXM graphics cards.

 

The models without the MXM graphics cards use the 135W P/S.

 

A discrete graphics card was not offered in the dc7900 USDT.

@Avalonhaze,

Are you sure you know the actual naming of the various submodels?

Look at the pictures on pg 2-1 and the description on pg 7-1 of manual.

Does not the DC7900 USDT have an external 135W brick style PSU?

That same PSU is used with the 8000 series USDT units.

Apologies for the very slow reply here. Yes it is definitely a DC7900 I'm certain of that and the power brick I have is as follows.

 

Input: AC 100-240V, 50/60Hz
Output: 19-19.5V 9.2-9.5A 180W
Connector: 7.4mm * 5.0mm

 

I believe the original was 

 

Input: AC 100-240V, 50/60Hz
Output: 19.5V 6.9A 135W
Connector: 7.4mm * 5.0mm

 

The Amps are higher so I think I'm okay to use it?

@Avalonhaze,

The voltages are correct. It will only draw the amperage required.  I do not forsee an issue.

I will ask an expert on those machines to chime in.
