390 Nitro PSU 8 pins

[IntelDiesel]

I have this PSU
http://www.anandtech.com/show/2395/7

Sapphire R9 390 nitro 8gig has 2 8 pin power.

I'm not seeing anymore cables in my psu box that would work for 2 8pin.



What do I need?

You should have 6+2 pin PCIe cables.

The problem is your PSU is old, so when it was built there was no such thing as an 8 pin PCIe connector. Best advice is to get a new PSU with the correct connectors, plus PSUs do wear out over time. That said, if really can't afford a new PSU, you can use a couple of 6 to 8 pin adaptors, but I don't recommend it. In theory the only difference between the 6 pin and the 8 pin is 2 extra ground wires (the live wires remain the same), this reduces voltage loss from ground wire resistance. If it uses 2 8 pins, there must be a reason the manufacturer feels the need to do so, so I recommend you get a PSU with the correct connectors.

SR71 If I can't find it what what would you buy as a replacement?

 

[Dark Lord of Tech]

EVGA G2 or GS 650W IF YOUR GOING TO RUN A SINGLE CARD SETUP.

I didn't word it correctly.
Can't I just buy a new PCIE 8 pin power cables if I can't find the included ones from a local big box parts store?

I figured my power supply I listed was still pretty dn good.

You need to buy one specifically for that PSU.

If you're missing a cable, call Silverstone. Modular cables are not interchangeable in this manner as the pinouts vary considerably.

 

[Dark Lord of Tech]

No you need to have the exact cables that would come with that model power supply.

Thank you Gentlemen. I was not aware of that.

 

[Dark Lord of Tech]

Glad to help.

Using the PCIE (2) 6x2 pins worked as expected. Thanks for all the help.
Fired right up and played Rust. Massive improvement over old gpu

Nice to hear.
