E3+华硕Dragon HD7850 2G要多少W?
推荐回答(4个)
选择电源大体需要计算一下平台所用的最大功耗 然后留出50w左右的余量保证稳定。拿您这个平台举例子
E3 1230V2 最大功耗 69w
HD7850 最大功耗 150w
主板硬盘内存光驱加在一起 50w
那么您这个平台的最大峰值功耗大概是 270w
再留出50w的余量 保持稳定性。那么也就是320w以上的电源就足够了。
实际购买中就推荐您买350w额定的。
华硕HD7850 大概就是1500块 350w的电源如果买一线大厂商的的
比如航嘉的 就300左右 比如航嘉冷静王至强版 300块
如果买一些其它品牌的 实惠的牌子就100多就能拿下 比如 先马超影450 169块
所以最低那就准备1600多 1700块就够了
450W够了
显卡可以用微星1G 1100, 2G 1300,电源300以内有很多选择。
华硕(ASUS)Dragon HD7850-DC2O-1GD5 910MHz/5000Hz 1GB/256bit DDR5 PCI-E 3.0显 1300
酷冷至尊 战斧二代 主动式400W电源 200
400w完全没问题 起码1500
