No. The smaller units are not as large as TFX they are smaller.
The tower can use an EPS12V power supply with MODDIY adapter.

EPS 12v units are HACKED into existence via using the power supply OUTSIDE the case.
The hole left behind by the removed power supply and the MODDIY adapter get this done.

Hi,
As per the system's design we suggest the users to continue using 290w power supply unit since the system's chassy and system's functionality are tested to be working best with these specifications .
If there are any more queries to reply to this post we will be glad to resolve them for you .
I hope this helps.
Kindest Regards,
DELL-Jennifer K

Reading the previous post about the "stock" power supply being enough for that persons needs. I hav a similar question. I am using a Optiplex 3020 with 16 Gb ram and a GeForce video card that requires 450 watt power supply per its specs which will be displaying to 4 tvs for a security system. Is there a larger power supply available for it ? These are machines which we purchase for our corporation for various mainly point of sale usage and I don't have a lot of choice in selecting a different machine?

No. I think you may need a graphic card with lower watts usage. Max power supply of this Dell is 290 ( or 300 in US).

Hi speedstep,
I am considering getting this adapter as I am in the same situation. A couple of questions:
Is it straightforward to mount a standard ATX PSU in the 3020 case?
The Dell PSU has 2 cables going to the board - an 8 pin connector (which the adapter clearly has) and a 4 pin connector (which the adapter doesn't). What would replace the 4 pin connector?
Thanks

That mean the GTX 750 Ti that doesn't come with 6-pin will work?
