Changes in power supply technology/standards/etc?

Alright. I want to buy a PSU, but I want it to be future proof.

I currently have an nForce2 with an AlthonXP. My current PSU is pretty sucky. 3y/o Antec 300Watter. Max +12V is 15A, +3.3 is 20A.

My plans eventually are to switch to A64 and a 6800GT. Eventually though, not anytime soon.

I'm deeply considering purchasing a TruePower 430 or 550. But now I'm hearing they are not as futureproof as people would've wished for. How long do I have to wait to get a new PSU? Or are there any others that I should get especially? Stock the Antec 300W is fine, but when I try to OC it doesn't help. I'm guessing cos the -12V line is WAYY too weak....
 
Well, the ATX12V version 2.x specification has made several changes to power supplies that should matter to consumers.

First off, the main ATX power connector has been expanded to a 24-pin connector which adds more 3.3, 5, and 12 volt power lines. This new connector is still backwards compatible with current motherboards, but future motherboards will require this new connector.

Next, a new connector has been established for the sole purpose of powering future videocards that use the PCI Express bus. It's a 6-pin design that will soon be required by many higher end videocards.

The four-pin ATX12V connector will stay, and the Serial ATA power connector has been officially acknowledged in this spec.

In order to have these new connectors, you'll need to buy an ATX12V v2.0 or higher power supply. I don't anticipate seeing any major changes being added for a while, so as long as you buy an ATX12V v2.0 supply you should be good for a while. Note that I'm referring to ATX12V version 2.0, not simply ATX.

Hm... Thanks. How do I find out if/which mobos support this?
 
If you need it for a new motherboard, it'll be pretty obvious in the specs. It'll mention a 24-pin ATX connector for sure. It's not a support-type thing; it's a requirement to run those boards
 
You know, that's such a great supply, I think you should send me one for testing :D
