I'm looking to SLI in the near future and I currently use 1 gtx 670 EVGA FTW superclocked gpu...my (dumb) question is whether or not my psu can handle 2 of these puppies. Thanks in advance for all replies
If you ask EVGA they will recommend 1.5 times the required system power for one GPU if you're running two in SLI. Single reqs for one 670 are 500w/30a, which would make it 750w/45a for dual card SLI.
Last I asked them about it they said it's right in line with what Nvidia recommends, so I'm questioning the valididity of the above claimed Nvidia recommended wattage, and no amperage is mentioned either.
Most 750w PSUs are going to have over 45a combined on the 12v rails though, so you should be OK. Keep in mind that the quality of the PSU is every bit as important as it's power rating though.
Thread is done and solved are you trying to claim his psu is not enough for sli ? i could careless what you question. As much as the power (Watts) requirement matters, the current requirement, measured in Amps is as important if not even more important. This is especially true if you have a or several dedicated video card(s). As a general rule of thumb, you’re aiming for the highest number on the 12V line.His Power supply is 62A 12V power it's more than enough to run sli 670
