what watt PSU do you have now? 180w?

800 G3, what is product code seen vast here.

IF TWR , I will answer.

as  rule (not all) PSU are custom PSU and custom jacks not standard ATX.

like HP 400 G3 is ATX PSU.

 280watts seems max, on ebay .. and custom power DC  cable, unique to  HP only.

there are only 3 places to look and see,  (generic answer too all PCs for sure not ATX spec) looking works. just at a glance

• rear side not   (5.9") wide  Tall (3.4") is not ATX (ruler time)
• then not over 5.5" long some go 9inches, and hit things, over 700 watts are  too long. for many PCs  (ruler time)
• then the 2 power cables that run the MOBO, if 3 seen with 7 pins that is custom PSU HP. if  4 pin and 24 pin that is ATX.
• and more, there are more cables needed if running a GPU card over 75watts , are you?

TOWER ONLY but not said by you. but here it is.
