H81probtc

1. Huaqing H81 Pro BTC only has four SATA hard disk interfaces. Two sata3 and two SATA2 generations.

2. The summary is as follows:
doskey Xiaohei = dir
doskey dir = echo bad command or file name
now the dir command will not be used, and it will be replaced by the Xiaohei I set
Enter dir to display bad command or file name, and enter Xiaohei which I set myself, which is the same function of dir before
knowing this usage, we can also disable dangerous commands such as fdisk, format, deltree, etc.

5. One of the cheapest 1150 pin main boards is
essence
advantages:
uses black high-end PCB panel, and all solid state capacitor, also can do workmanship, three-phase power supply, to satisfy the introction of cesson processor
disadvantages:
only one VGA [without on-board digital input HDMI and DVI], and there is no front 3 (after loading 2), the interface shrank seriously. Chip cooling is also general, there is the motherboard BIOS and XP compatibility is not good< Summary:
H81 motherboard is the most cost-effective motherboard, which is a good choice for office users and beginners

6. Yes, but Mingying is a mixed brand. You might as well buy a brand new mixed brand rx580 graphics card on Taobao, which is guaranteed for more than 400 years. CPU can buy an E3 1220v3 four core processor in Taobao, more than 200.

7. Hello, ASUS a78m-e is the boss. He is the motherboard supporting AMD CPU. Huaqing H81 Pro BTC supports Intel CPU. The price of ASUS is dozens of yuan higher than that of Huaqing. AMD CPU is cheaper than Intel CPU. It depends on you. If you want to use AMD, choose ASUS motherboard. If you want to use Intel, use Huaqing motherboard
