I find it ironic that the DIY crowed is talking about PSUs that have a rating of close to a thousand Watts and when you buy an OEM desktop, it'll have a 300W PSU. Even, the OEM with i7-3770 CPU and AMD Radeon™ HD 7570 1GB GDDR5 comes with a 460W PSU...
I did try this link and i put in my graphics card and the rest of the important stuff. Somehow it calculated a minimum of 300 something Watts. That is irrelevant because my card expects 400W min.

The HX650 is a very good choice, I have two. In my opinion a PSU with a single 12V rail and active PFC (Power Factor Correction) is always best.

That is likly the usage that you would have if Idle under load it would be much higher a Graphics card can use inbetween 75 to 150 w from idle and up to 200 to 500 w underload

My apologies. I'm out of date. www.newegg.com lists many 80+ Gold or Platinum units at prices that aren't absurd. There are a reasonable number of choices even if you put a lot of filters in their Power Search (80+ Gold or Platinum, single 12V rail, modular, active PFC). It's a good place to look for information even if you cannot (outside of US or Canada, or no credit card), or will not, do business with Newegg.
