Hi everyone,
i recently got an old optiplex 780 (sff) from someone who doesnt need it anymore.
I was very happy with the pc because my other one (dell inspiron 531) was getting really slow and stuff... I knew that i was going to get this computer and i thould that i could upgrade it so that i can play games at medium settings.

The problem with this pc is that it is the sff model. This means that i cant really upgrade the psu (stock : 235w) to a normal sized 300w one to add a video card for gaming. I Searched for days to find a solution and i found a few ones : 1. buying a new case
This is probably the best thing i can do atm but i dont know what case supports the mobo from the optiplex 780
2.buying a new motherboard MSI G41M-P33 Combo socket 775 so i can put it in a normal case .
3.adding an external psu (spare 300w) to power a decent graphics card wich is shown in this video https://www.youtube.com/watch?v=HKq9rcLzJMw (not sure if this will brake my components or video card.


Please give me your opinion on my problem and possible solutions

Thanks !

Sorry for my bad english , im Belgian

I wouldn't go higher than a GeForce 750 or a Radeon R7 250 or R7 260 on 300W PSU, to be honest. Otherwise, yes, what you're planning most likely could work, but I'd recommend a better PSU if you're throwing a decent graphics card in the mix.

Thanks for the quick reply !

I think im not going to add a second psu because of al the cabels and the case is so tiny so i guess the only thing i could do right now is buying that motherboard and getting a bigger case ? Then buy a 450w orso psu and when ive got the money buy a decent graphics card...what graphics card would you recommend that doesnt require a 6 pin connector and is good with 450w ?

My recommendation would be the 750 Ti for that requirement. It's a low-power card that can run easily on 450W and doesn't require a 6 pin connector and is only around $150.

Not sure why you'd have to replace the motherboard, though, unless it doesn't support a dedicated video card. The current motherboard should screw in fine into a normal size case.

It might fit, but after googling and looking at the board, it is weirdly long instead of wide. I would go ahead and get the motherboard you were planning on, now that I've actually seen what it looks like.

Assuming this is the baord in your system:

It's strangely opposite to the usual ATX standard in that the PCIE slot is at the top of the board and the RAM is at the bottom, so that would fit very awkwardly in a regular case. I would recommend a new motherboard.

Okay i will buy a new one, just one question : the cpu fan is not directly above the cpu but at the side , idk if this would fit on a new motherboard , dell makes there product so that you cant really mix it with other components ...
