Title: Do i need two power supplies for my rig? Post by: ninjagod on August 28, 2017, 07:39:22 AM Ive seen almost every rig have two power packs/supplies.
Can i get away with just one? Title: Re: Do i need two power supplies for my rig? Post by: MATHReX on August 28, 2017, 07:56:04 AM Well, what is the model of your GPU and how many are there in one rig? It all depends on the power consumption of the complete rig.

No, absolutely not.Can i get away with just one? Only AMD GPUs have to have 2 PSUs because they eat a lot of Watt. With an nVidia RIG, even a 6 x 1070 GPU, you can have only one PSU.

You have to be ready for a significant increase in noise but server PSUs are of platinum grade (better power efficiency) and are cheaper than consumer PSUs.

6 GPU rig examples: Example 1: 6x Rx 470 intro with 6x 6pin pci-express risers. Two evga supernova 750 G3 power supplys woyld be enough. Psus havet 6+6 8 pin pci-express cables. Example 2: 6x Rx 460 2 gb, NO 6 pin. One evga supernova 750 G3 with 6 pin risers would be enough. Conclusion is that gpus matters and how many Connectors your psu havet.

That depends on what PSU or which pair of PSUs you plan on getting, along with all of the components that your system will be composed of. Considering the other threads you've made, you have no idea what your system is going to look like, so it's too early to answer this question. I suggest that you learn the general process of assembling a desktop PC prior to messing around with a GPU mining rig. Title: Re: Do i need two power supplies for my rig? Post by: Vann on August 28, 2017, 10:37:37 PM It depends on how many cards you plan having in the rig and how many power connectors each cards requires. The total watts is only one factor. Another factor is number of PCI-E power connectors you need for the GPU's. If the PSU doesn't have all the VGA power connectors you need for the cards, you may need to use a larger PSU with more VGA connectors or a secondary PSU to have enough VGA power connectors for all the cards. Another consideration is when going with a 1500 W or more PSU, two smaller PSU's are cheaper than a single larger PSU.
