Use online basic psu calculator assuming i5-10600 for 7080sff, 32gb ram, gt730 gddr5, Sata hdd 7200rpm, no optical drive, Load Wattage: 183 WRecommended PSU Wattage: 233 W if you include dvd RW recommended psu bumps up to 263w. 200w is on the weak side but able to support system normal operation. good thing is 7080 mt and SFF psu have same TFX form factor and are virtually interchangeable.  200w psu is the standard psu for SFF per tech sheet because Dell considers that most users do not need 260+w psu in SFF for business use.  You may be able to order 260w psu for MT to be configured with SFF, if Dell sales is able to accommodate your custom need.  If Dell can not sell you that, buy a 260W psu for 7080MT from third party if possible. PS 7080MT depth=11.84 in. (300.80 mm); 7080SFF depth= 11.53 in (292.80 mm) [IMAGE] 7080 SFF [IMAGE] 7080 tower [IMAGE] 7080 tower
