ATX case and 1U PSU

I found this Prototype case which I am thinking about buying:

I think it is super cool, and it is very small for an ATX case.

The thing is it uses a 1U Power Supply.

I don’t know anything about a 1U PSU, it looks like they are server power supplies.

If I get the case, what do I need to know about 1U power supplies?

They seem to only go up to 300 watts, is that enough for a P67 motherboard and a single graphics card like an HD 6950?

Also, will the power connectors fit a P67 motherboard?

The power supply will not be sufficient for that configuration. No way, no how.

 

The power consumption of the HD 6950 is more than 300 watts when under load so the PSU you suggest is not enough for the graphics alone (see chart)and you need power for the rest of the PC.

If you intend to use the HD6950 you will need a minimum 500watt PSU but of course bigger would be better.
