1. Dumb,
Dumber,
People who get excited by high-wattage power supplies.

2. Agreed. What's the point of a 950W PSU when the current it brings is identical to typical 400W/500W PSUs that are widely available and cost a crap load less?

Why not just wire a pair of 500W ones? It's ALOT cheaper!
(There's sources around the web that tell you how to do it).

3. looks like the power supply to use for an SLI 2x6800 Ultra rig

4. Provides more watts but the same amount of current?

Wattage = Volts x Amps

Would the author care to elaborate on what is meant by this?

5. The article says that each 12V rail can only accomodate 14-18A, which is the maximum for most PSU's on the market. I think the PSU achieves its high wattage by providing several 12V rails, each with the 14-18A limit. Today's high-powered ATX/EPS12V PSU's probably use two rails, maybe this PSU uses 3-4?

6. Usually all the 12V lines run back to a 12V node in the PSU. I can see where your coming from though. Seperate 12V sources for ATX12V line and the molex and sata lines. Possibly the same for 5V in the atx connector and 5V that goes to drives.

7. I fail to see why one would buy a $500 PSU from a relatively unknown manufacture with a rated continuous output power of 650-750W. Better options, if you want that much power in a single PSU would be:

1. The Enermax 660W (EG851AX), for about $250

2. One of the (non-ATX) switching PSUs from Delta, rated as high as 5'000 W !

3. Buy quality components from an electronics catalog, and build a PSU yourself, as powerful as you want it to be. (PSUs are pretty simple.)
