<p dir="auto">上面我说长城电源的客服回复我，指的是电源出来一个8pin大约230w,那么我一张显卡双8pin的供电，用两根分开的线，接电源上面两个PCIE8pin的供电口，一块显卡就有460w的供电能力，是足够7900xtx使用的。</p>
<p dir="auto">如果你的7900xtx是3个8pin供电，而不是2个，最好问一下厂商，电源线应该怎么接。</p>
<p dir="auto">x99的e5，算150w,两块显卡一共700w,再加上主板上一些其他的内存啊外设什么，总共算1000w功耗，1250w的金牌电源从理论上来说余量是完全足够的。</p>
<p dir="auto">当然了如果你还有其他的，或者以后可能用更加耗电的设备，一步到位用1600w或者2000w电源也没错，成品增加不多。</p>
