OK I have an AOpen 400w PSU right now. with +12V @ 16A and Medion here at NV News told me that 16A is way to low for a new A64 MoBo, A64 CPU and 6800GT, He said I need at least 22A on the 12V.

I have found a couple of good cheap ones at newegg. But what is Dual +12V?
how is the +12V rated? I was looking at this one...

but the +12V is rated +12V1@16A,+12V2@18A so how does it work? and would that be a good PSU for my system?

System in Siggy!
Thank you. ;)

Dual +12v rails is actually split +12v rails. If you add them up, you should get a decent idea about the overall +12v rail. So, that PSU would have 34A on the +12v rail.

I have no knowledge of that particular power supply, but there is more to choosing one than just the label specs. Quality and reliability is a big factor with these units. If you buy a cheap unit, you will probably get what you paid for. And, I can tell you from experience, that it is no fun to have one go out. There are some good comparisons available, but you will need to Google for them. I would also recommend buying a tester, they are cheap and will quickly answer any questions that might arise.

The only question that I would have, is that even a company that puts out a lesser product, doesn't necesarily have a consistent quality. You might just have been lucky and got a good one. I don't know anything about Aspire, but the local PC Club had them in stock. But I would rather be safe. I have never seen the best quality sold at the lowest price.

I never claimed it to be the best but the price/quality ratio is excellent imo. I might have just got a good one true but look at all the other reviews on newegg.And if you were to get a bad one, newegg has a very generous return policy.

I understand what you are saying, and I am not against anyone saving money. The only reason that I believe as I do, is because I had a series of power supply problems, and not being all that good at diagnosing problems, this caused me alot of problems. It is good to have good support, but it is better not to need it in the first place. I scrimp and save anytime that I can, but I would rather do this with something that is not indespensible.
