GTX1070 in an Inspiron 3881 - PSU / space
Hi there - I currently have a DELL Inspiron 3881 micro tower and am looking to move a NVIDIA GeForce GTX 1070 8GB into it from another machine. I'm interested to know if this will physically fit, but also if I will need to upgrade the PSU. The 3881 PSU looks like a low-profile / SSF one, but don't know if the case will take a standard PSU. The GTX 1070 has an 8 pin power connector. Many thanks for any help - Ben

If you already have the card, you can measure to see if it will fit. You will need a higher capacity power supply with the required connector, and you almost certainly will not find one that will fit inside the case -- it will need to remain outside the chassis.

@ejn63 Thank you for the reply - I was dubious about the PSU. I wonder whether a new machine might be the way to go, rather than the external option! Thanks again.

You can see which GPUs others are using in the Inspiron 3881 over at userbenchmark. BUT, that site doesn't tell you what size PSU is installed in any of the systems listed...

you just need a dell psu that has an 8 pin to power the full height 1070
The Dell oem 1070 will fit chassis (it is a mini tower)
The Dell oem psu 360 w fits the chassis too.
A 360w Dell oem psu is sufficient for GTX1070 in 3881 (assuming i7-10700 etc.)
psu estimate
Load Wattage:321 W
Recommended PSU Wattage:371 W

PS never mind Nvidia recommends 450w for 1070 that is typically overestimate. Dell 360w came w a 6 pin. use a 6 to 8 pin adapter for 1070
