So, my PC build will use 467W at max, recommendations are to have a psu with 10-15% watt output for best efficiency. In time I want to add another GTX 980ti to my system, I'm wanting to buy the EVGA 750W 80+ Gold Certified Fully-Modular ATX Power Supply but I'm worried that for the first 3-4 months that I have the PC without the second graphics card, that it will be an overkill and give me less efficiency..
Is this true? Do I need more watts? Will I need less? (My GPU is Gigabyte 980ti extreme non-water cooled drawing 250W each)
