Recommended PSU for DELL OptiPlex 780 SFF

[Kosenator]

Hi there.

 

I am in process of upgrading a DELL OptiPlex 780 SFF and wish to replace the PSU (255W), with a more powerful one. Is/are there any SFX unit(-s), that is/are highly recommended by professional system builders?

 

This is basically to be a nice-to-have system, for when a decent gaming system such as my main PC, is not available.

 

The GPU I wish to get is recommended to have at least a 300W PSU, which is my reason for this post.

AFAIK, the Dell Optiplex 780 SFF doesn't actually use a SFX PSU.  It's more like a proprietary version of a TFX PSU.

TFX - I learned a new term! Thank you!

 

I did a quick search, and mine is this:

The dimensions seem to fit within the range of SFX, though I admit I am new to these small-scale power supplies.
