[SS SST-ST85F] Converting dual 6 pin PCIe connectors to a single 8pin

[orestesp]

I am re purposing an old Silverstone SST-ST85F Fully Modular 850W PSU.
However, it lacks PCIe 8pin power connectors, so I had to buy a cable from ebay that converts the dual 6 pin PCIe connectors on the power supply to a single 8pin connector, in order to power my RX 480 (pic related):

(The cable converts 2x6pin PCIe male connectors to a single 8pin female connector, which will then, through a male-to-male PCIe 8pin cable, will power the GPU).

Is this going to work or is it going to fry my graphics card?

How old is this PSU? Twin 6-pin to one 8-pin adaptors do work but I wouldn't risk an old PSU with a new card. Any decent 850W PSU should come with 8-pin cables, unless it's so old it dates back to before 8-pin PCI-E cables existed.

Here's a page that lists its specs:

Support dual PCI-E 8 pin connectors & quad PCI-E 6 pin connectors

I shouldn't have any problems with it, right?

I salvaged it from a C2Q system that came with it.

Is there anything I need to look out for with the cable I am using?

I currently have a VS 550, could it be worse than this?
The system it was used for didn't even have a discrete graphics card that required additional power.

The connection is fairly straightforward

It won't fry anything, right?

Where did you find those reviews?

It won't fry anything. Using 2 6-pin to single 8-pin has been around for a long time. Some cards still come with the adaptor.

Hard to say what's worse, the Silverstone or the VS550. The VS series are cheap units using some budget parts. They're the cheapest Corsair PSUs available. Personally I would use neither, as the PSU is arguably the most important component in the system but if I had to choose, I'd go with the VS. as it's newer.

If this is the correct model, here's a review. Page 4 is disassembly showing the internals:

Teapo caps aren't that bad, they're better than some of the other cheap Chinese brands. Main thing is that caps age and cheaper caps will age quicker. That PSU also had some ripple issues. These issues will only get worse with age.

I heard that Teapo caps just don't like heat, which shouldn't be an issue in my case (rated for 85C instead of the usual 105C).
The PSU probably wasn't even used that much in that old system (it had an entry level C2Q with some random passively-cooled gpu).

Is it that bad?
What's the worse thing that could happen and how possible is it?

Hopes and dreams ruined.
Any particular SuperFlower PSU that you'd suggest for my build? I'll probably have to buy it from somewhere like Amazon since they don't have it in my country.

Thank you for your time.
