Inspiron 3030S and 3020S Small DT Buyer beware

commonly asked psu and gpu upgrade options for S (Small DT)

the S is the slim and cheaper entry level of Inspiron

this model has very limited upgradability

user should know this before decide

3030 small desktop can only accommodate up to 300W Dell oem psu for Optiplex,

Dell does not even offer the 300w psu in 3030SFF spec, only 180w.

another evidence of this being a low end entry model.

3030S and 3020S are 92.6 mm wide only

there are two different types of Dell oem 300w psu

their dimensions are:

(1) 186 x 120 x 63 mm​ (120 mm wide not good for Small Desktop)

this has a black 8 pin PCIe connector for gpu
