Asking about adapter

[KudaJurus1st]

Halo all,

so I just checked online that the 780ti box has 2x 2 molex to 8 pin adapters. Unfortunately the box and the cable got lost. In my power supply there are only 1x6+2 pins and 6 pins, That means i need 1 more 8-pin (the card needs 2x8-pin). The question is, is it better to use 2x Molex to 8-pin adapter, or 6-pin to 8-pin adapter. BTW my psu is teamseven st-650w 80+ bronze and I don't think I will be buying a new psu any time soon.

 

Thanks

That is a sus PSU.

 

It's a split rail design from what I can see, so you have two 12V rails; rail #1 provides 20A and rail #2 provides 30A. Make sure you're running that card off rail #2 for best results, it is hopefully labeled on the PSU outputs.

 

As for adapters, either one will work "fine" but they're not great solutions for the long run. Thankfully a 780 Ti isn't the worlds most aggressive card power-wise. They're typically 250W TDP, so roughly 20A sustained current. Hence why I suggest making sure it runs off rail #2.

First of all, thank you for answering. And I just found on the internet that 2molex to 8 pins supplied a maximum of 120W and 6 to 8 pins only 75W. If you were me, which one you will choose (in the case of not buying a new PSU)
