GTX 970 - 6 pin power supply instead of the required 8 pins

Hi, 

 

I've bought the new GTX 970 and apparently my power supply only has two 6 pin connectors. 
My power supply is the "
EA-430D GREEN POWER SUPPLY" from Antec. 

For the GTX 970 I need 8 pin connectors.
Is there anything I can do, or should I buy a new power supply? 

Thanks in advance

Tom

@tomthecomputernoob Welcome to the forum! :)

 

I checked the official website of the PSU manufacturer and the PSU only has one 6-pin PCI-E plug. So that means that it's not compatible with your GPU. That being said, most graphics cards come with power adaptors these days. Did yours come with something like a Molex to PCI-E 8-pin adaptor? That could help you. 

If you don't have that, you'll pretty much need to upgrade your power supply. I suggest getting something like a Corsair CX500M, Seasonic G Series 550W, or a Corsair RM550. Pick the one that fits your budget better!

According to the official geforce website here, it says

 

Supplementary Power Connectors 2x6-pins

 

You should be fine, although 430W may not be beefy enough, especially since the website recommends at least 500W

According to the geforce website you need a "Minimum System Power Requirement (W) 500W" that being said you can get a two molex to one eight pin adapter, just check the wiring before plugging it in to your graphics card.

Thats not true. My whole system takes in the worst case scenario 430W-450W (after OC) and I have a lot more power hungry components. He will be fine with 430W... still even with room to OC.

 

(Just use molex to 8-pin if you dont have 8-pin on PSU).

usually cards which have 8pin connectors come with adapters from 6 to 8 pin. The power requirement by the manufacturer is usually way overkill so you should be fine with your psu as long as you dont overclock like crazy...

These connectors aren't optional, without them the card simply won't work.

 

You can use molex to PCI-e power adaptors, but make sure you get ones that use 2 molex connectors as one is not enough and could be dangerous.
