400W电源可以带gtx760冰龙独立显卡的。
一台电脑选择电源，不能只考虑显卡需要多少瓦电源，需要全盘考虑。
电脑耗电量大的只有三个，一个是主板，一般需要电功率在20-30W。一个是CPU，因为品牌不一样、型号也不一样，需要的电功率就范围较宽，在50-100W。再一个就是显卡了，显卡的GPU不同，耗电差别非常大，不过可以根据它是否有辅助电源插口，插口采用几针的，来做一个简单判断，电脑PCI-E接口最大供电能力是75W，如果显卡不带辅助电源插座，说明它的功率不会大于75W，一个6PIN显卡辅助电源插座，可以供电在75W，一个8PIN显卡辅助电源插座，可以供电在90W。电脑其它硬件耗电都小于10W。
GTX760冰龙独立显卡，本身带两个6PIN插座，说明它的功耗在225W以下。将所有电脑硬件耗电加起来，总功耗在不会大于390W，所以使用400W电源去带这台电脑是没有问题的。
振华400w电源完全能够带得动你说的gtx760显卡的，放心吧！这个品牌的电源质量很过硬的。r9
280x是要比gtx760强一点点，但功耗的确很大，为那么一点性能也要换电源就不划算了。不存在什么瓶颈，果断买下显卡了。但我建议你买映众的唷！技嘉的也可以。反正你别买花屏王凄惨红的显卡。
GTX760冰龙的TDP功耗是206W，+12V1 18A是专门给显卡供电的，12*18=216W，所以你电源可以带起。+12v2 18a是给CPU、主板等供电的。I5 3470也就满载77W。足够的！放心吧。

截取部分：
功耗部分，只有Furmark拷机一项，560Ti整机满载输入功耗低于760，其余项目均高出后者几十瓦不等。由于测试采用的游戏画面设置高，显卡实际帧数比较低，功耗也相对较低一些。在把画面设置调整到流畅运行（>50fps），并开始垂直同步后，也就是玩家日常使用的一般游戏状态下，GTX 760都能稳定在300W左右的功耗状态，一般都在270-300W左右波动；而560Ti则是340-370W，功耗降低很明显。还记得照片部分埋的悬念，760的8+6pin和560Ti双6pin谁更耗电的问题吗~（注意我这里是采用额定550W的电源进行测试，由于平台不同以及显卡满载温度的不同，功耗会有不同，建议想购买GTX 760显卡的玩家还是至少要配备一个额定450W以上的好电源。）
太勉强 新的没问题 永久了对机器不好最好额定450W
