I would get a Good quality PSU. Don't just get any name brand. I would check some of the PC Power and Cooling, Lepa, Seasonic, Antec, Corsair, Thermaltake, Raidmax, and Silverstone
You have to remember that power consumption fluctuates. I would always reccommend at least 20 to 25 watts more than what you need. But that reading doesn't seem all that right. 625w - 650w maybe? Also, does the website reading add these watts together at idle stages, minumum, max, or what? It could be many things.
This is what was thinking, It seems overkill. I though a 500 watt would cover it. Im kinda a noob when it comes to psu's but this probably the issue. This wattage was calculated on a 90% load, so would a 500-550 watt still be ok if i dont go 90% on it? Probably not right? I guess Ill just go for a 600+ ocz one cause they are dirt cheap
I ran a 955BE@ 3.7GHz, 2 HD 5850s @1GHz each on a 530w Rosewell green PSU, which was the cheapest best value PSU at the time, which the 630w green PSU is now, and they have nice amp rating as well as 80+ certs
