I believe Enermax have the highest commercially available PC PSU. I doubt very much you need that much power though, what are your specs.

What do you need to power? Fifteen hundred watts is a lot of juice. Enermax makes good PSUs which review very well; Antec and Seasonic tend to review even better. Prices go crazy as wattage goes up, so if you can gauge your requirements better, you might save a lot of money.

Unless you have an extremely overclocked pc system with 4 video cards operating in quadSLI mode you do not need a 1,500 watt power supply.

The general rule of thumb is a high quality 500 to 550 watt power supply with sufficient current (amps) on the +12 volt rail(s) can easily power a system with any single video card made. A high quality 700 to 750 watt power supply with sufficient current (amps) on the +12 volt rail(s) can power a system with two video cards operating in dual mode. There are a few exceptions like the new ATI Radeon HD 5XXX series cards which use less power due to their energy efficiency.

A high quality 500 to 550 watt psu will have a +12 volt rail rated at 40 amps. A high quality 700 to 750 watt psu will have a +12 volt rail rated at 60 amps.

In addition the power supply should be at least 80+ Bronze certified for energy efficiency. There are some models available which have achieved 80+ Silver and 80+ Gold Certifications.

Corsair and Seasonic are two of the brands that have a reputation for high quality power supplies that consistently earn high marks in technical reviews. They are reliable, stable, and come with a 5 year warranty. Some of the newer models come with a 7 year warranty.
