Could anyone provide a succinct description of the differences among these power supplies.  I am looking for a 1600W supply and had hoped to find this either in the FAQ or product descriptions, but could not.  Is it just the energy rating or are there other differences I should know about? The T2 and P2 are out of stock and I’m trying to decide whether it’s worth the wait.

    Bronze/Silver/Gold/Platinum/Titanium is the efficiency rating..Most PSUs run at maximum efficiency around 50% load..You can use the OuterVision Power Supply Calculator to estimate your system's wattage draw/need or use a Kill-A-Watt/Usage Monitor to find out exactly..It's more important to get the right wattage PSU..A higher wattage PSU with low load (overkill) might not be as efficient as a lower wattage one at higher loads.

    Thanks. That makes sense and I understand the efficiency ratings. I was just wondering whether there were any additional differences. Based on this, I will likely go with the 1600W G2, since that is available and meets my output needs, even if it is not the most efficient product in the portfolio.

    Clearesult.com has a good breakdown of the 80 plus program and the ability to look up power supplies along with their specific efficiencies. Interestingly there are other efficiency ratings that are sometimes reported like ETA and lambda (some more real world conditions and relationship to noise). Interesting if you have the time to look into.

    I’m curious, are you planning a dual GPU build?

    Yes, I am thinking about it, but I haven’t gotten as far as evaluating GPU candidates. I also already have a Corsair AX1200i on hand from a previous build and haven’t decided whether to cannibalize that.

    Thanks so much for this. That’s is exactly the kind of data I was hoping to see.

    Setting up a dual GPU is a lot of effort and you'll need a case that supports to GPUs
