Do I have enough power for my machine?

Use the power supply calculator to find the wattage rating that you'll need:

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.

I linked him to the HX650 by Corsair........semi-modular, 80+ Gold and plenty of PCI-E connector for video cards. All that for less than $100.

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 I'm out of date.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.
