Solved i5 3570K vs AMD Athlon ll x3 450 power consumption Tags: Power Consumption AMD Intel i5 CPUs Last response: July 12, 2014 3:39 PM in CPUs Share teunkoerts July 12, 2014 6:43:35 AM Hi, Currently I'm running a very cheap PSU in my system. I'll provide a photo in this thread. It's 430w I believe. It was a pretty big guess when I put my HD7850 in but it's running fine. So when I replace my motherboard (with H81/H87) and get a i5 3570K from a cousin will it still run fine power wise? psu: http://m.imgur.com/T53jsYk My system: AMD Athlon ll x3 450 HD 7850 Don't know the mobo 4gb 1333mhz crucial ram 500GB HDD 60gb ocz agility 3 ssd 3 led fans and some other leds in my case. no dvd drive lol thanks!

Otherwise you could fry the lot, with a poor PSU. any decent XFX 550w psu like this one will suffice : https://pcpartpicker.com/part/xfx-power-supply-p1550sxx... the I5 3570k is still a beast, so if your gonna get it, go for a z77top end z75 board to compliment, cos your gonna wanna OC that baby at some point. No point in hindering it with a Hxx/Bxx mobo.
