Any word on PSU requirements for DX10 cards

[StevenNevets]

I'm probobly getting a 430/450W PSU for my new rig and shall be upgrading to a DX10 card in the future

Does anyone know about the PSU requirements, hoping this would be enough for a 7900 GT alternative

well current top end cards require at least 500w and 20+amps for them, so figure higher.

umm... not from what I see???

System Requirements Minimum of a 450 Watt power supply
Minimum 550 Watt for SLI mode system

They'll have different levels of DirectX10 cards just like they have different levels of DirectX9 now most likely. To stay safe I would say 400w (although 350w might cut it in a simple system) on up.

The power output equivalent of 1.5 neutron stars. Won't come cheap.

If you can afford to buy a card that needs a secondary GPU PSU, than you can probably afford the extra power supply too.

I'm going to be one of the serious ones and say 500W for a single card system, and 600W for a dual.

If this whole thing about next gen cards taking up around 200watts is true...well...you'll just needs as much as you can get.

I was actually half-serious in my previous post. Get a reasonable PSU now that can support one mid to high-end DX10 GPU and if you end up really needing more power for SLI/Crossfire, grab one of those secondary PSUs. They are under $100. I think past performance has demonstrated that unless you buy both cards at once you will probably not buy a second one later as the next gen card will be faster, cooler, offer more features, etc. No reason to spend extra for "future-proofing" if you will not likely use the capability and the mitigating factor (I.E. secondary PSU) is not very expensive in relation to a second video card.
