I'm building a:

AMD 64 3500+
Geforce 6800 256mb
512x2 dual channel RAM
Asus A8n SLI dlx mobo

Is the 400w PSU that came with the Antec case going to be enough?

Hi,

I am assuming its a Antec psu but what is the model number of the psu?

check the amps on the 12v if it has 20A or more it should be enough.

I don't know how to check the amps, I looked on the side of the PSU, but it's all greek to me :tazz:


This is the exact case I bought with PSU specs at the bottom:

Does that help? Or can you tell me what letters/numbers to look for on my PSU if that link doesn't help?

yep that helps alot, heres the specs on the psu (specs)

Notice the +12v under max load it says 18A, this is the minimum Amd recomends for your cpu so technically it should work, however most users of 64 bit processors recommend the +12v be in the mid 20's especially if you are using a high end video card.

So my recomendation is to try it but if you have any problems get this Antec

Thanks a bunch!

So I'm just going to be scraping by? If it isn't enough, what kinds of signs can I look for? Will my system be overheating, or just shut off?

Also, I'll probably be buying a new PSU in the near future so that I can run a second 6800 in SLI, will the 480 be enough? Or should I just go for a 550 to be safe?

As far as signs to look for, you could have problems with the video card not playing games correctly, this is usually mistaken for a driver problem that updated drivers don't fix or the system might freeze. I have seen some try and run a 300w and wonder why there video cards don't work even after updating the drivers I am purely speculating at this point. I would not worry to much you are within spec.

With what you want to run in the future maybe the 550 would be best

Thanks again.

I'd just like to take a quick note here to thank the staff and other users here for just being so [bleep] helpful. Easily the best forum of this nature I have ever visited. Building this PC would be excruciating without you guys.
