The power draw on my UPS is typically showing around 205W load at present and jumps up to about 350W when actually playing WOW. I have been occasionally smelling a burnt smell from the PSU. Seems to me I may be pushing the limits? Maybe this card is a bit much for my PSU?
External Power - 6-Pins:2
Minimum Power Supply Requirement:500 watt
XFX Recommended Power Supply:XFX 650W PSU
■500W (or greater) power supply with one 75W 6-pin PCI Express power connector recommended ◦600W power supply (or greater) with two 75W 6-pin PCI Express power connectors recommended for AMD CrossFire™ technology.

You should be more than fine, unless the PSU is failing for some other reason. Load-wise you're more than ok. Heck, a Seasonic G360 should run that setup easily.

Antec also use CWT, Fortron and HEC to make cheaper models. Seasonic makes their flagship stuff.
Seasonic stuff tends to be expensive, but sometimes you can get deals.
Cheaper Corsair models are made by CWT, pricier models are (can you guess?) Seasonic.
The fact that some of the biggest PSU names use Seasonic to make their flagship lines speaks volumes about Seasonic quality in general.
