Since I liked myself, I have been very concerned about the various indicators of the hardware. In fact, there is only one computer that is completely independent, and this is the 3A machine (AMD + ATI + ASUS) that is currently in use. It is already 2013. Nowadays, memory has long been dominated by DDR4, but I'm still looking around for DDR3 1866 offers. However, when the agricultural enterprises relied on RAZEN to turn their backs, they could only hold back the impulse of the collection, and honestly searched for improvements that could improve the current performance and stability of the machines. In fact, this is related to their own character, and after all, it is 80, and the bad habit of reluctant to throw things and spend money is still slowly changing.
Let's take a look at my 2013 DIY's first PC configuration:
My current power supply was bought in a certain East in 2013. ONDA rated 400W Power Ball King 600 Track Master Smart Edition. Motherboard: ASUS F2A85-M motherboard, CPU: AMD APU series quad-core A8-5600K boxed CPU, memory: G.SKILL SNIPER 4Gx2 DDR3-1866, graphics card: Dataland HD6570 Hengjin 1G 650/4000 1G/128bit GDDR5 PCI-E 2-piece mechanical disk, in addition to the CPU cooling fan, there are two 12cm chassis fan.
Reasons to purchaseOf course, even if they are not willing to spend money, Zhang Aunt’s various gods will repeatedly be brainwashed, and they will continue to have a kind of grasshopper behavior. Today's desktop power can be said to be a "must-have". Because after reading someone's "her" computer to detect a malfunction, after replacing the power post, he began to pay attention to the power that he had neglected before.
The fool-proof method of the Xingu GP700G power supply and the computer ATX power supply Recently, the friend's computer often fails to enter the WINDOWS system after booting and powering up. Familiar with computer DIY, I was called to solve this computer problem. After testing with the minimal hardware method, it was determined that the CPU, memory, graphics card, motherboard, and hard disk were all OK, and I would suspect that the object pointed to the power supply. Because the friend's computer mounts more drivers, there are two mechanical hard drives, a solid state hard drive and an optical drive, when the computer is used by Fad Li | Likes 5 Comments 39 Favorites67View Details Actually, in the process of using computers recently, there are indeed several things that may be related to insufficient or unstable power supply. Here to share with you, hoping to get expert answers and recognition and to remind me as much as the power of knowledge of the value of my friends.
The first is to hang a Seagate mobile hard disk.
Of course, I watch video directly on the mobile hard disk (I would say I do not see big sister you letter, right?) May be the main reason leading to hard hang. Fortunately, it was bought in a certain east. During the warranty period ... but because of the wear of the SN code, almost no sale. Fortunately, at the end of the day, it is still refundable, which is equivalent to free use for almost a year. But the things inside will not be found. Therefore, I would like to remind you in the meantime about the value of your friends. First, do not watch videos or run programs directly on mobile hard disks (especially mechanical hard disks). First, you must protect the SN codes and reduce the wear and tear caused by yourself. However, I feel that I have not touched the mobile hard disk during use, and suddenly the system is stuck and the hard disk hangs up. I speculate that there is a certain relationship with unstable power supply. Of course, this phenomenon is difficult to reproduce. Due to my experience, I can't confirm how much responsibility the power supply problem has.
The second thing is that one of my hard drives always goes out. I installed Ubuntu on this hard drive and booted the dual system as the main drive. However, during use, it is often not possible to boot the hard disk and it must be restarted several times to find it. Later, simply pulling the hard disk. The first thing I thought about was the hard disk itself or the ASUS motherboard. However, after reading the post, I feel that the lack of power supply may be the main reason. After changing this power supply, at present, this phenomenon has not reappeared. For the time being, it may be considered that there is a lack of power supply, but it will take some time to verify.
The last thing is my dual monitor, the secondary monitor always goes off. After using my 19-inch 23-inch monitor for my brother, I would like to try the dual monitor directly. However, for a few days, the sub-monitor would not work. In the end, you can only use the return monitor. This also deepened my suspicions about the lack of power supply. After changing Zhenhua, it is also possible to use the dual monitors more stably. The reason for using “more stable†is because yesterday the desktop icon has been refreshed for several seconds repeatedly, so the problem of the graphics card or system is still not doubled. The main reason for the instability of the display.
After confirming that the original power supply may be underpowered, I began to pay attention to the power supply product. The original PO's main post recommended that I buy the EVGA G2 550W power supply. Of course, the quality is good and the price is very touching. The current price is 600 yuan, which is far higher than the psychological bottom line of 1 yuan and 1W.
EVGA SuperNOVA 550 G2 80 Plus Gold Rated, Fully Modular ATX 12V/EPS 12V ECO Mode Power Supply 220-G2-0550-Y1623.3 Yuan Amazon China Direct Links However, the product of another GQ code of the same model of the EVGA is much cheaper. After asking the valued friend, the defendant, G2 is a foundry of Zhenhua. It is considered to be the quality first team, and GQ is a Chinese-made OEM. We must be weaker. Therefore, the goodwill of "Zhenhua" power brand has increased a lot.
It has been entwined between domestic brands such as EVGA and HuntKey, but after seeing Zhenhua's own brand power, it is considered a good choice for compromise. So the first time in a certain East "second kill" activities, to 20 yuan discount superimposed Aunt's 16 yuan ticket won in one fell swoop!
Zhenhua (SUPER FLOWER) rated 550W iceberg Kingdee 550 combat version power supply (80PLUS gold / support back line / 5 year warranty) 369 yuan Jingdong direct link I have a nickname in my friend called "packaging men." The main reason is that I like how to disassemble my favorite products and put them back. Even the outermost plastic cover must be opened with minimal damage. So we can ignore some details in the following figure
The first is the appearance: (positive and negative sides)
Then it's true, out of the box:
After the above bubble opens:
The 80 PLUS watermark of the warranty card, by the way, is the first time I bought 80 brands of power, but also Gold, I feel very strange.
The contents are also very simple:
Screws, power cords, and the power supply itself, what's the bag? Moisture absorption agent, such as the power of this semi-open electrical appliances, wet should be fatal, right?
The following main look at the appearance of the power itself:
The orange paint is still very bright. Active PFC, should be the standard power supply, right? But there are value-friends that this fan of the power supply is fixed speed, is to save the circuit to adjust the fan speed? This kind of large-mesh power supply seems to be very common, and I remember that power supplies were relatively closed long ago, and later they all have such a large-looking appearance.
The interface is the same as the removed power supply, so the interface has no special surprise except for the text logo:
Take a look at the nameplate of this power supply.
According to my recent research, the closer the power of +12V to the total power, the better. In addition, +5V should not be too low. While a single +12V can bring about a less restrictive power distribution, it can be said that under certain conditions, the probability of some power shortages is reduced. Although the dual (multi) road +12V also has its advantages, but I have a comprehensive comparison, from the perspective of cost and practicality, or a single road is more suitable for me. I don't know much more about the deeper parameters. At this time, according to my logic, I chose the high-priced products of Dachang and used the prices for additional safety and quality.
Here are some details of the comparison between my original power supply and the existing power supply:
The original power supply was Onda's ball king 600 master (smart version). At that time, the 80 plus concept had not been heard. It is also on the Internet to find someone else's configuration card as a tiger.
In fact, the nameplate of this power supply is not bad, if it is really as the nameplate shows, it is enough to cope with the power supply of my host. However, there are details that make me think this power supply still has problems:
From this picture, the 12-point mark below the 12V mark on the far right is “Dual 12V†(the original image is enlarged and visible). This description is not consistent with the nameplate! The contradiction between these two details has caused me to drop a lot in the evaluation of the original power supply (virtual label? poor material supply? insufficient supply?)
In addition to the parameters, in fact, from the outside, there is no obvious difference between the two power supplies:
Look inside the previous chassis:
I made a back line:
However, this chassis is really bad, I hope you God to recommend a better one - I use the table below, and would like to change a 488 video card.
Take a look at the case of replacing the chassis of Zhenhua Iceberg Kingdee. The first is the rear of the chassis:
It still looks very coordinated. Then there is the internal situation:
As you can see, I have to add two hard drives in order to detect the power supply capability of the power supply. There are a total of four hard drives! Should be full of all SATA card slots. The top piece is the most expensive Western Digital blue disk 1T, but a little block memory, so I changed the memory to the CPU side to plug it in order to make the power cord flat behind the hard drive.
The back line feels better:
After everything was inserted, it was already midnight.
Fortunately, once lit, dual monitors, 4 hard drives! And it has been a few days since it was used, and I feel that the whole is relatively stable. There is some noise that should be caused by hard disks and fans.
From personal experience, I still recommend everyone to choose this product. Cost-effective and value are not bad. The conversion efficiency of the 80 Plus gold medal can be said to be a very safe choice. Of course, the cost of this is a matter of opinion. Zhenhua, as a foundry of the EVGA G2 first-line products, has the quality of its own brand in the middle of its class. Compared with the price of more advantages but the word of mouth Xingu, HuntKey and other brands of products, I personally would be willing to pay some more cost to stay away from these saliva......
As people age, most people will go from "price sensitive" to "price insensitive" - ​​or "quality sensitive." I personally feel that this is a relatively positive and mature change in consumer philosophy. Looking at how many elderly people suffer losses of tens or even hundreds of thousands for small profits, I will introspect myself about my own consumption concept. Although in any respect, the price as the first frame of reference for people's consumption is indisputable. But when it comes to consumption, it often overlooks the "costs" other than prices, such as time, energy, and "opportunity costs" that can be used to consume other commodities. These costs are often much higher than those we pay less. One example of the most vivid image is a paragraph: Bill Gates saw ten thousand dollars on the ground on the road. He would not be embarrassed because he would lose more money when he spent the money (although this paragraph was later covered Citz himself would also quibble with his answer of $100, but his answer is not in contradiction with the economics of "opportunity cost" reflected in the paragraph itself. My personal experience is that for the first time, I went to Zhongguancun to buy a laptop. As a result, everyone can guess that because of some small profits, I actually bought the first "netbook" of my life for a premium of nearly one thousand yuan.... The profound lessons of similar experience have led me to think constantly about the fatal weaknesses of my outlook on consumption.
Saying more, in the end, thanks to the platform of Aunt Zhang and all of you, you have the existence and sincere advice, I can continue to get useful knowledge and insights, and this Zhenhua power supply is regarded as a questionnaire I submitted. , I hope you God tapping ~
