[SOLVED] Can I use a 6 pin to 8 pin adapter to install gpu?

[Coldburnout50]

So I’m new to building computers and I have built my first one. I decided to upgrade my gpu and install a xfx R9 390 amd radeon. When installing I noticed that I had a 6 pin pcie that would fit but my psu doesn’t have a cable that is 8 pin for the other side. I looked online and noticed that there are 6 pin pcie to 8 pin adapters. I have an extra pcie 6 pin cable from my psu and was wondering if I could use this adapter to connect to my gpu.

You can use an adapter if you're trying to fry your components. PCIE adapters are a common source of fires and are almost never recommended. Pretty much any PSU that doesn't have an 8-pin connection isn't one you actually want powering a discrete GPU. But for a more detailed response, you'll have to provide the exact PSU you're using.

I’m using a rosewill 500W RD500S 2SB

This one? It has only 372W on 12V rail.
Xfx R9 390 requires 500W PSU minimum. Xfx recommends 550W psu.
Get a new PSU.

Here’s the link of the one I’m using

Stallion Series RD500-2-SB - 500W ATX12V v2.2 Power Supply - Rosewill

www.rosewill.com

also what psu would you recommend? Also another question is do I need the 6 pin connected and the 8 pin to power that gpu?

Yes - both 6pin and 8pin have to be connected.

This one is decent option - for example
Seasonic S12II-620

You need an 8 pin.

This PSU dates from the bad, old days of Rosewill, before they tried to sell competent PSUs. This is an ancient, group-regulated, Solytech-made PSU.

You need a new PSU. An R9 390 can spike near 300W. This is an inappropriate PSU to pair with this GPU. This might be adequate enough if this were a lower power card that doesn't require supplementary power, like a 1050 Ti or a 1650, but this is a hard no. And it would be hard no even if this power supply had two 8-pin connectors.

Not a lot of good PSU sales at the moment. This is probably the least expensive PSU I'd run with an R9 390.

Ok thank you will definitely check it out I’m willing to spend around $100 for a psu if that helps with any recommendations
