BFG 8800GT power supply consumsion

My current computer model is GM5474 its a gateway and it has a 400 Watt psu with a combined voltage of 12v 1 and 12v 2= 30 A now I dont know what that means but is that enough. thanks:)

400W is pushing it, especially for some no-name brand PSU. I would say minimum 450W, optimally, 500W.Spartan8907

The watts are not such important if it has enough A on +12V rail

well are my Amps enough. thanksoblivion1010101

yes they are but if you want stability get a new PSU like Antec EarthWatts 430w

Well the wattage and amperage ratings of your PSU are more than enough.What people mean by stability is that PSU may not be good quality and may die if it's pushed hard.It's your choice whether you want to run your not so cheap computer with an unreliable PSU.

And well you DONOT have to spend 200 dollars on a quality PSU.If you want to get a new PSU then just get the corsair VX450 watt.You can get it for around $80.
