The $170 Seasonic X-750 provides a positive first impression when we unpack it. The 750 W PSU is stowed away in a black velvet case, while the cables come in two nylon packs. Except for Corsair, Seasonic is the only manufacturer in this roundup to use a fully modular cable management system, with even the ATX and CPU cables being modular (though the value of this is questionably, since you're probably not going to use a power supply without hooking it up to your motherboard).
The fan on the Seasonic X-750 only starts running at loads above ~250 W, otherwise staying perfectly silent. The 750 W PSU is 80 PLUS Gold-certified, and its single +12 V rail (preferable to all of the units with dinkier +12 V output spread over multiple rails) can handle up to 62 A.

FLanighanWhy not Corsair? I jizz at my tx850w
The article doesn't appear to measure noise from during switching and how much noise is introduced to the CPU and bus.
Anyway, it will be a cold day in hell before anyone gets me to switch out my Silverstone 1500 Watt PSU.
I call BS. I could run your setup with my PC power & cooling 750w unit.
