Inspiron 3880 PSU 300w Upgrade

Inspiron 3880

My desktop is an Inspiron 3880. I need to upgrade my GPU to an ASUS GTX 1050ti, which requires a 300w PSU. The included PSU is 200w. I purchased a 300w PSU from Dell on referral from a Dell representative. However, this 300w PSU has different connectors.

Two questions:
Is there any way to use this 300w PSU with my desktop via adapters?
Can I use this ASUS GPU without upgrading the PSU?

Thanks in advance for help!

Read these threads, here and here.

PC may not boot with the existing PSU if it can't handle the load from the new GPU, and that extra load could cause damage.

And keep in mind that you may have to disable Secure Boot in BIOS setup, before installing any after-market GPU or PC may not boot. So make this change after you get the new PSU connected and everything is working properly with the existing GPU. Then swap in the new GPU...

You cannot use the 300w psu. It is meant for Inspiron 3910 and newer models which use 8 pin Dell proprietary connector on motherboard. 3880 uses older 6 pin connector. The 8 pin and 6 pin out are completely different and incompatible.

You could purchase a Dell oem 360w psu that has 6+4 pin c/w 3880. there are also 260w oem psu compatible too.

you could try test the 200w for the 1050ti but gpu may be underpowered. No harm is done doing the test. Worst case scenario pc would shut down.
psu calculator shows load wattage is 211w using nvme ssd only w 1050ti in 3880. so 200w is just a bit low.
