12代cpu全部参数
作者：我是四海飘零
前言
让我去小黄鱼买二手电脑配件我自己是不太愿意的，但是身边就是有人敢于尝试从海鲜市场（小黄鱼）上淘二手的电脑配件来找我帮忙装机。考虑到每个人的需求和接受都不一样，所以我站在自己的角度来说不太愿意去购买二手的电脑配件，尽管价格较低但是考虑到售后质保，我个人是强烈不推荐购买二手的，除非是品牌支持个人送保。
装机配置单
因为CPU、主板、显卡是身边朋友从海鲜市场（小黄鱼）上淘二手而来，剩余的电脑配件则是从拼多多上购置的全新配件。
CPU
小黄鱼上也会有一些价格不错的产品，比方说这个12代i5处理器，零售版肯定是比那些所谓的“ES”、“QS”处理器都要靠谱，好歹也是带KF结尾的处理器，只要能点亮就没啥问题。
主板
我这位朋友执著非要上Z790主板，说是买新不买旧不考虑上一代Z690主板。在目前的市场上，华硕、技嘉、微星、华擎的Z790主板基本上都没有低于1400元价位的，二手的价格也在千元价位。反正是图便宜，精粤Z790M主板在小黄鱼上也有人卖，二手八成新的价格不到六百元的价格，说实在还是蛮划算的。
包装盒上也能看到精粤这块主板的参数信息，不到六百元的价格去买块二手Z790主板玩玩那还是很值得的。
包装盒里有一份质保卡，一根SATA串口线，一块8成新的精粤Z790M主板。
板子的成色还行，但是实际上主板上还是能找到不少二手瑕疵的，比方说散热片的划痕肉眼可见还是较为明显的。
Snow Dream（雪之梦）明显是有模仿华硕吹雪的嫌疑，从散热片的布局上又更接近华硕PRIME大师系列主板的造型。
精粤Z790M主板采用了后置一体式I/O挡板，接口分布如下：USB 2.04，USB 3.2（红色）2，USB Type-C1，DP1，HDMI1，CLR CMOS按钮1，WiFi SMA1，DEBUG指示灯1，2.5GbE有线网口1，SPDIF1，音频输出接口1。
在精粤Z790M主板上有3个M.2 SSD插槽支持NVMe 1.4协议、GEN4.0速率的固态盘。
主板拆开看细节
可以看到精粤Z790M主板的图示说明，该有的接口基本上都有，就连前置Type-C接口都有预留，扩展性还是可以的。
14+1+1 Dr.MOS供电模组，这个供电数量带个i7处理器实际上也是完全没有压力的。
PWM芯片：RT3628AE（最大支持8+1相供电），所以我也没整明白精粤是咋支持14+1相供电的。
微距拍到的主板Dr.MOS供电模块特写，说实话做工细节还有待进一步提高。
这颗NCT5585D芯片其实是Super IO芯片，主要用于监控主板上各个硬件的温度、转速、电压等信息的。
精粤Z790M主板也是用了小螃蟹Realtek ALC897的集成声卡芯片。
这个价位上能用上小螃蟹Realtek RTL8125BG芯片还是很良心的，这个是2.5GbE Ethernet Controller（以太网控制器），也就是说有个2.5G网口传速速率会比千兆网口更快。
目前精粤Z790M主板还不支持在BIOS里调节RGB 5V和RGB 12V的接针，只能等后期BIOS更新支持了。
内存
内存用的是宇瞻黑暗女神NOX系列的RGB灯条，这个是DDR4内存，可以一键开启XMP支持到DDR4-3600频率，还支持超频到DDR-4000频率。
显卡
显卡没有考虑用NVIDIA 30系的矿卡，非矿的3060Ti G6X显卡价格也不便宜。朋友也是选择了在小黄鱼上入手蓝戟A750 Photon 8GB显卡。
蓝戟A750采用了三旋帆翼风扇，能提升风扇的散热效率，也支持风扇智能启停，在低功耗下做到静音，在满载下做到满速加强散热。
蓝戟A750整张显卡重量控制的不错，前面板用了聚碳酸酯材质，在提供强度的同时也保障了框架的稳固。
蓝戟这张显卡隶属于Intel ARC阵营，作为I卡的合作伙伴显卡的外观质感依旧在线。
蓝戟A750延续Photon系列的全包裹设计和DEBUG灯光，搭载自研灯控Blues具有监测电源和主板的供电故障的能力，便于判断问题定位，的确是个很不错的设计。
A750也重新设计的金属背板也能有效的防止PCB变形，提高了显卡的韧性。
蓝戟通过五根镀镍散热管+高密度散热鳍片搭配三旋帆翼风扇的组合打造了更高效的散热系统，优化了显卡的散热压力。
蓝戟A750拥有3个DP接口和1个HDMI接口，对于有需求外接扩展多屏幕的用户来说是个很好的选择。
蓝戟A750显卡内置了28组Xe Core核心（448 EU执行单元），最大GPU频率：2400MHz，显存容量：8GB，显存类型：GDDR6，显存频率：16Gbps，显存带宽：512GB/s。有两个8PIN供电接口，供电相数：6+4，最高支持PL1：195W。
电源
电源采用了全电压供电设计，独家定制的3D电路+LLC谐振拓扑+DC to DC稳定电路方案，在减少电力损耗的同时，还能提高稳定的电压输出。
电源依旧是推荐艾湃电竞650W电源，全日系电容，通过了80PLus金牌认证。官方承诺10年换新，只换不修。
机箱
机箱推荐用的是九州风神魔方CH370，外观颜值和体积都很均衡的一款MAXT机箱。
九州风神魔方CH370机箱颇为好评的就是机箱的前面板永久了不会觉得单调。支持1秒变脸，内置了可移动插件，轻拉即可改变机箱前面板外观效果。
九州风神魔方CH370机箱在前置面板上带有一个伸缩的耳机支架，可以外挂头戴耳机还是很方便的。
水冷散热器
为了压制Intel Core i5-12600KF的散热压力选择了九州风神冰堡垒240。
九州风神冰堡垒的外观造型在一体式水冷散热器里算的上是非常好看的。
九州风神冰堡垒240水冷头独有的双光环无限反射ARGB冷头，而且冷头也是用了大尺寸的紫铜基底，能够给处理器提供更高效的散热。
装机展示
经过一番装机之后的亮机效果，等后期精粤Z790主板BIOS更新支持RGB灯控后，应该可玩性会更高。目前是依靠九州风神冰堡垒240自带的RGB灯效和宇瞻黑暗女神NOX内存的RGB灯效来维持“高颜值”。
精粤Z790主板的后置一体式I/O挡板对于装机用户来说还是很方便的。
点亮CPU后查看精粤Z790M主板的BIOS版本：A09，目前已经刷BIOS更新到A12版本，可惜的是BIOS UI界面依旧是第二版的UEFI图形界面。
目前精粤Z790M主板的BIOS更新还是今年1月份的，这说明精粤还是没有给Z790M主板更新到最新版的BIOS UI界面。
跑个鲁大师测一下性能，综合性能得分：161+万分，Intel Core i5-12600KF处理器的性能还是蛮强的。
总结
不介意二手的话，其实CPU、主板和显卡购置二手其实还是能很大程度上降低装机的成本，当然其他配件也选择二手的话还能再压低装机的支出成本。基本上CPU坏的几率不大（除非运气背，那就没办法了），只要能点亮就没问题。主板和显卡只要还在保修期内，硬件没有问题也是可以的。显卡只要非矿的二手问题就不大，就怕是矿卡冒充二手坏了那就比较麻烦了，还得看显卡品牌的售后政策。强烈建议电源一定要买全新的，电源图便宜选个杂牌或者寨牌的电源一旦炸机大概率硬件烧坏的情况还是蛮大的。
