Anyone ever heard of this power supply?

I'm going to have a system built for me. I have compared thru 3 sites, ibuypower, cyberpowerpc, and monarch. Monarch is the most expenisve comparing apples to apples so they are out. Both of the other sites rec this power supply NZXT PF-500 500Watt Power Supply. Anyone ever heard of it? Anyone know if it's ok. I play to run my system stock (at least for long time) and it's basically 4400 x2 and 2 7800gt sli. So what do you think, will it be ok?
Here are all the specs I could find from both sites:

Just to be safe i would stay away.... depending on who makes the PSU, not just brands it, will tell alot about the quality. If you need a good 500w PSU look at Fortron, OCZ, Emacs, Zippy, Antec, ThermalTake, Seasonic, Silverstone (Zuse only)

I think they only come with NZXT cases. I have one for sale in the trader section...
