Powering GPU

[Frank0110]

I have a Lenovo thinkcenter with a Lenovo Mahobay 8PINS mobo i7 3770 with a GT1030 2gb . Obviously the PSU don't have any pcie connectors .
Iwant to upgrade the GPU to GTX1060 6gb running on a 8 pins pcie 
what is the best option ?
Running the GPU on another PSU using only pcie 8pins or swapping the psu and get a 24 to 8pins adapter to power the whole system , i know the last option will keep my system running even when shutted down 
so i am scratching my head right now
will a separate psu backfeed power to the PC through the pcie slot ? 

sorry for the english , i speak french and computer wise i am a total noob

Lmfao my bad im just a boy

yes mobo 8 pins power
       cpu 4 pins power

so i want to know , am i better to have a separate psu to power the gpu or get a 24 pins to 8 pins adapter and swap the main psu and will using a separate psu feedback power to the pcie slot ?
i check those sata to 8 pins pcie but i read it is a no go

um im trying to imagine what your saying, is there a separate CPU and motherboard power? and if not a CPU 8 pin should work.

A CPU 8 pin power connector does not work as PCIE 8 pin power. They're pin out and connector are both different, if you manage to force an 8pin CPU connector into the GPU you're going to fry the GPU, PSU, or both.

 

I'd edit your reply and fix that before someone actually tries it.

i tried 8 pins power as a pcie but it dose not fit the socket on the GPU

Since it's an oem Lenovo desktop we'd need to know if it uses a proprietary power supply or a standard ATX. If it's proprietary you can use a second PSU with a 24 pin jumper plate to power just the GPU. Or, if it can fit standard ATX power supplies, you can simply replace it with a standard unit that has the proper wattage and PCIE cables.

yes it is proprietary , so my best option would be an external psu with the jumper plate ?

is it a better solution than a new psu with a 24 to 14 pins power adapter ?

That or with the age of it, you could likely find a Dell Optiplex or other OEM prebuilt for cheap with a better CPU and the proper power connectors for pretty cheap. 8th and 9th gen i7/i5 prebuilts are pretty commonly available on ebay for less than $100.

Those adapters are usually fine as long as your positive it's the pinout for your motherboard.

thanks a lot for your help !

If you don't mind taking up two wall outlets, just get a separate PSU that's only for the graphics card. No need to touch wiring that's already there

No worries, if you do decide to look into the newer tower route, the Precision 3630 supports standard ATX PSUs, though they're more in the $200 range that's with an 8th or 9th gen i7, 16GB to 32GB Ram, and a 256Gb to 512GB SSD plus Windows 11. I'd look around though, if you go that route just look for an 8th gen intel or newer that supports ATX power supplies.
