MSI 1660 Super power question (safe?)

[-Adz-]

Hi,
Would really appreciated some guidance on the following:

Bought a MSI 1660 Super to upgrade a bargain PC I got from work for gaming.
The PC has a weird PSU (685w) which has its own board, on that board there is an 8 pin power_VGA2 port, furthermore the PC came with a 8 [male] to 2 x 6 pin [male] connector currently unused, 2 pins on the 8pin side are also unused/ empty.
The 1660 Super has a 1x 8pin port.
I looked around and most cables out there are 8 to 6 pin connectors however I managed to find and buy a 1x6 [female] to 8 pin [male] adapter.

So I will end up with:
8 pin port on PSU board
Connected to:
8 pin (2 pins unused) to 2x6 pin connecter
Connected to:
6 pin (1) to 8 pin adapter
Connected to:
8 pin port on 1660 supper

My question is:
Is this setup safe and will it provide enough power for the card (normal and overclocked states)?

Your help & time is much appreciated.

To be perfectly honest my brain melted trying to understand what exactly you have going.

Let me see if I got it : you have something akin to a modular PSU that has an 8 pin female connection going to an 8 to 2x6 adapter which is going to a 6 to 8 pin adapter ? What I don't understand is why didn't you just get an 8 pin extension cable ?

You should buy a new PSU to be blunt.

Sounds like the OP ended up with some kind of an Optiplex (well, not really those things don't come with PSUs above like 300W, but you get the gist) their workplace decommissioned. These things tend to have both proprietary PSUs and logic boards.

Tbh, your best bet would be to get a 1650 that can draw all its power from the PCIe slot.

Sound about right, got confused my self writing it
Most of the connections that I found (available online) are 8 to 6, i did however find a 6 to 8 (https://www.amazon.co.uk/dp/B01DV1Z32Y/ref=cm_sw_r_wa_apa_i_y3SoFb2D5ZZF4) which i thought could work.

A new PSU is possible, however I was trying to save a bit of cash with what i have if it works.

Similar to an Optiplex, a design tower, namely a PRECISION T5610.
Already bought the 1660 since i saw an 8 pin port and a 685w seemed sufficient.

So in conclusion, this setup is not recommended?

Power is not a problem, using those adapter chained like that ... ehm. I don't know how they are wired to guarantee that there wont be any problems.

I posted the link because I had a similar issue a while back with an HP Z620.
Had to get the correct cables to power the 1070 I wanted to install. Can't remember much else but it worked.

Just plug the 6 pin connector directly in to the card, the extra two pins are for extra current which isn't really needed in such a low power card.

Thank you for the feedback.

Great, that is a really usefull article.

I'll give that a go i guess.

Thank you for your time and help all.
