Need Help -- PSU for Phenom X4 Build Tags: Power Supplies Build Phenom Components Last response: January 31, 2009 3:12 AM in Components Share MjBinkley January 31, 2009 12:22:12 AM Hello all, I finally convinced my wife to allow me to build a new computer, old one was an AMD FX-55 based machine. New one is as follows: AMD Phenom X4 9850 BE BIOSTAR TFORCE TA790GX 128M 8GB OCZ Platnum DDR2 1066 ATI Radeon 4670 1GB I do not intend to Overclock for at least the fist 3 months. No plans for Crossfire at this time. How big of a PSU do I actually need? How do I calculate the required PSU as I have not actually purchased the items and therefore do not have the specs? Thanks in advance for your advice. More about : psu phenom build theAnimal a b ) Power supply January 31, 2009 1:24:24 AM If I were you I would get a Phenom II instead. They perform better and overclock better as well. AFAIK when you run 4 sticks of RAM with a Phenom it won't run at 1066, so you may as well get some 800 instead. I would also buy RAM rated at 1.8V (G-Skill & Mushkin are good). I don't think you'll notice the difference in 1GB versus 512MB on a 4670. As far as the PSU, a good quality 300W+ would be plenty. I'd suggest Antec Earthwatts 380 or 430, Seasonic S12II 380 or 430, or Corsair VX450. MjBinkley January 31, 2009 3:12:57 AM Thank you, really appreciate the advice. Especially on the RAM as I was not aware of that issue. You just saved me a bunch of cash. Can't find your answer ? Ask !
