Replacing my 6 years old PSU, seasonic prime?

post #1 of 3
Thread Starter 
so the seasonic prime psu is on sale, the only problem i find is that it the 750w model, although not entirely accurate, these online power calculators did give me a good idea of how much wattage i actually use. and it turns out my Load power: 361 W.

i want to get the prime psu, however i keep reading about how the more wattage the psu the lower the effiency it would be running at lower loads. so since i'm idling around 95 watts, and loading around 361-400. am i still going to get the 94 percent efficiency at not even 10 percent idle?

According to Johhyguru's review of the 750, it looks like you will maintain the efficiency very well across all loads.
