OptiPlex 990 SFF PSU Upgrade?

Hi everyone,

I have read on places like Toms Hardware that I can upgrade my pay on my system, but then i had a friend tell me that my components in my PC are only rated for 250W. So could someone who is sure please tell me if i could upgrade to like a 350W psu.

My system is a Dell OptiPlex 990 SFF:

I5 2400

Integrated graphics (I want the psu upgrade to upgrade my gpu)

500gb Western Digital HDD

Hi Governor Keagan,

We see that OptiPlex 990 SFF supports only the given specification for PSU. Small form factor 240W and this system is not tested with 350W.

Please get back to us for any further questions or clarifications.

Looks like you can't, small form factor dell's have proprietary power aupplies which cannot be upgraded even if you could it would make no difference due to the motherboard configuration. Only mini tower dell's can use atx power supply upgraded.
