Hardware & Technical 8 to 6 pin PCI-e Adapter!

[CMDR Cosmic Spacehead]

Hello!

My friend is using my old PSU and GPU for his new build (for the time being).

My old GPU requires 2x 6 pin PCI-e connectors.
And my old PSU has 1x8 and 1x6 PCI-e connectors. The 8 pin is NOT a 6+2, it's fixed.
I used to have an adapter for it, but it's not in my box of random PC parts. So it's basically gone. (God knows where, i never put any PC parts anywhere else!)

And I can't seem to find a replacement on eBay or anywhere.
There's loads of 6 to 8 pin adapters, and even 8 to dual 6/8 adapters, but no simple 8 to 6 pin, or even 8 to 6+2... Help!

If anyone can link me to a cheap UK seller, that'd be grand!

Have you tried the Alibaba website ?

Once I found a Sata adapter at a very good price

Do not, go for the cheapest of the cheap, go for something in the middle, there's unfortunately quite a few incidents out there where too cheap adapters are simply poor quality and cause accidents.

Lol I found one for £1.15 from China. What could possibly go wrong!

I read somewhere that if the GPU allows, you can just stick the 8 pin in to the 6 pin slot, and leave the other two pins hanging over the edge... Does that work?

The difference between 6- and 8-pin is a ground wire indicating to the graphics card that the power supply can push out enough power over that connection (enough power on the rail and big enough wire gauge). You can technically put an adapter in there, but there's no guarantee that won't lead to spurious system shutdowns or fire.

You can get SATA to 6-pin PCI-E connectors.

Or if you don't have a spare SATA you could always use a Molex to 6-pin PCI-E like this https://www.scan.co.uk/products/aka...pin-to-6-pin-power-cable-adaptor-ak-cb4-6?v=c won't be pretty though And you would need two spare Molex with female connectors. No idea on the "safety" aspect as mentioned by Shadowdancer.

You can get SATA to 6-pin PCI-E connectors.

PCIe 6-pin power: 75W. SATA power: 3 12V pins, Molex specs their crimp terminals for those at (a lower limit of) 1.5A which would make for a total of 52W. Add a 6 to 8 pin connector and you have something that tries to draw up to three times the rated current through that connector.

This one is rated up to 80W: https://www.amazon.co.uk/UGREEN-Exp...Z0BQ/ref=sr_1_6?ie=UTF8&qid=1521288401&sr=8-6

I want to see the independent certification for that rating, and you still need something capable of that corrent on the other side of the SATA power connector.

Amazon marketplace merchants are selling a lot of shoddy electrics, including mains equipment that exposes live parts or spontaneously bursts into flame while doing nothing.

Found one! It's far too long, but it'll do.

Seems good for the price

I remember when I went to use an old power supply for a new build, there was something about new CPU's dropping power that can affect older power supply that isn't compatible, just something to be aware of.
a quick search found this.

One thing I never scrimp on when I build a new system is the power supply.

this, as shadowdancer pointed out above as well, dont play with your PSU

It's only a temporary PSU until he can afford a new one. It did come with its own 8-6 pin adapter, but it's vanished.

I've told him it's really old, and he WILL need to replace it before buying anything else. Same for the 7 year old GPU.

But it ran my (almost identical) rig perfectly fine for 3 years, and my previous rig for about 6-7 years before that.


It is really OLD. lol
