Dell Optiplex 390 SFF PSU Alternative
Hey there, curious if there's a PSU alternative (240W) for my 390 SFF.
According to this video www.youtube.com/watch?v=I7_enEWxJyM the guy have a bigger PSU in his SFF. Its a 3020 7020 9020, it looks identical to 390 SFF. Can anybody confirm it can fit in 390 SFF? Or what other Optiplex SFF PSU is transferrable to 390?
Thanks
Currently equipped:
Optiplex 390 SFF A14 BIOS
250GB SATA 3.5" HD
i3-2120
Planning to upgrade:
Bigger CPU to i5-3570
Convert to SSD, possibly 2 SSD

that psu has an 8 pin ATX proprietary for 9020 series motherboard. you can not use it for 390 motherboard which has a 24 pin ATX socket. you are looking for a TFX psu to fit SFF. The stock psu for 390 SFF is 240W. Dimensions: 72mm x 62mm x 240mm
replacement psu needs to be around same size to fit inside case.
