Guys, I know this isn't really lomac related but I'm trying to build a new computer for LOMAC and it's my first AMD A64 computer ever. I'm a little confused as far as power supplies go. I don't have a zillion forum accounts so I thought maybe someone here could help me.

 

Which power supply would be sufficient for an AMD64 with either a 6800 Ultra or Radeon X850XT and only 1 HD and a DVD burner? Oh and I have 2 small cooling fans in my case. I really want an Antec PS cause I have an Antec case. I'm confused cause I read all these things about making sure I have enough amps on my +12v or something like that and not sure what they talking about. Also I do have the SATA power connector on my HD and also a PCIe graphics card I want to get so do I HAVE to get a PS with the PCIe connector on PS? Please if anyone knows which PS will work I appreciate the help. thank you

Bought myself a Thermaltake Silent PurePower - 420W Solution - W0009R, for my P4 socket 775. with a BFG6800GT/OC. It does the job verry nicely. Not that expensive also.

1 6800 Ultra at its default frequencies (i.e. power consumption) eats smth. near to 7.6A at +12V line.

1 A64-939 CPU needs smth. close to 8A at +12V line.

 

So, speaking of power consumption, each one of the models listed here would be enough.

 

Concerning connectors - obviously, it's convenient to have a proper one at the PS, but there are converters that allow using old-style connectors as well. Those converters usually ship with the PCI-E video cards requiring external power supply. As well as the SATA power converters and the motherboards.
