不過NV官方好像推薦G80單卡瓦數要400W (好像+12V超過幾安培)
之前忘了在哪有看過功耗建議表了 
我還是建議您可以的話，先未雨綢繆換PSU，畢竟如果真的350W不穩(輸出安培數不夠)
有可能會影響甚至損害到週邊，這也是很難說的事情，防範勝於治療 (誰叫G80這麼耗電)... |

貼了某網站的實際量測資料 (整機、含電源供應器的浪費)

他的裝備：
* Intel Core 2 Extreme QX6700
* NVIDIA nForce 650i SLI based motherboard
* 2x1GB PC2-6400
* NVIDIA GeForce 8800GTX
* PowerColor ATI Radeon X1950 XTX
* Western Digital Raptor 150
最後的結論：
...DailyTech previously reported NVIDIA recommends a 450-watt power supply for a single GeForce 8800GTX graphics card. This isn’t too farfetched of a recommendation.
Power consumption of NVIDIA’s GeForce 8800GTX isn’t as bad as expected. When compared to AMD’s current flagship ATI Radeon X1950 XTX, the GeForce 8800GTX only consumes 24% more power at idle. The power consumption differences under load decreases to around 4%. Considering the performance differences, the GeForce 8800GTX is no worse than AMD’s ATI Radeon X1950 XTX in terms of performance-per-watt....
