I have a 500W PSU from Cooler Master. I recently went to Microcenter and the tech told me that I need a minimum of 550W PSU (suggested a 600W PSU from Thermaltake) and the 500W PSU I have will not be enough.
I used the Newegg power supply calculator gave me a rating of 361W which is much less than the 500W that I have. Can someone tell me if I can use the 500W PSU or was the tech actually correct in saying that I need a minimum of 550W (the supposed formula was NewEgg value + 200W). If the 500W is enough, I would like to use it so I can reduce creating more electronic junk in the world.
If you are paranoid with your computers you would know better than to buy $40 600w power supplies.....you get what you pay for.
With an HD6570 you can get by with a quality 400w power supply. Since Coolermaster tends to be crap you are fine with the 500w model you have.
Either the Microcenter tech was an idiot or he was trying to make a commission off selling you that Thermaltake power supply or both. If anything Thermaltake is even worse than Coolermaster.
So keep what you have now. If you ever upgrade to a decently powerful video card you will need to upgrade though. Stick with Corsair, Seasonic, PC Power and Cooling, XFX, Silverstone, Enermax, OCZ, and Antec for quality brands.
