Recently it is very obsessed with computer power. I also bought a second-hand power supply and spent two days. I haven’t found a problem yet, so I’d like to share my experience
For many people who use computers, the time that the computer accompanies them can be said to be longer than that of the pro. Therefore, it is necessary to invest money appropriately in computers. In my opinion, the power supply chassis can be used for 10 years if it is used well. I now have a computer, which was installed in 2006. Everything in it is changed, leaving the chassis and power.
Chassis, I will not say more, if you are willing to, you buy a 700,800 rave reviews of the chassis, absolutely not wrong, but to over a thousand, if non-fever professional, it is not recommended.
Focus on power. The most eating power, is the cpu with graphics, cpu can be used to load more than 100w, graphics card, I use gtx 980ti as an example, overclocking full load can exceed 300w, other peripherals, set aside 100w, almost. Here we must be rated 500w power supply. Many friends do not understand what is rated, I personally explain it unclear, or Baidu.
In considering what to buy after the video card, what cpu's friends, Baidu under their respective full power, and then add a 100w, you can go to pick. For example, I am very ambitious, I would like to go on i7 6700k, and then a pair of gtx titan x sli. In this way, my cpu is 100w, titan x is a 300w (insurance point, count 350 is better, anyway, you have to buy power, not bad one hundred and two hundred, last better) so even if 100 + 300x2 = 700w, then Plus a 100w, is 800w, so I will look at more than 800w rated power. If I only use e3 + single card gtx 970, then 80w + 250w = 330w plus a 100w is 430w, so different cpu, graphics tend to choose different. Local people do not care.
Select the required power rating, we must choose the power supply, in general, are based on brand, 80plus ah, ah module module to pick. Buy a new power source, I suggest to go to Jingdong, or go to a nearby physical store (if it happens).
If you have a brand, here's a website. Everyone can refer to:
Then choose 80plus, the most cost-effective words, is the bronze medal, if the ability to allow, try to buy a gold medal or more. Relying on platinum, not only power conversion rates and other issues, but also quality problems, overclocking problems will be better.
Then on the module, personally think that the best half-module, peace of mind, full-module, then it. Not mb line cut. . . Anyway, we must use it. Anyway, we must hang the mb line. Why? . . . The only advantage is that the custom module line. . . Appearance Association can engage in, faith beliefs can be engaged, what led lights, light pollution, what you like. . . I personally don't like it.
The above article on the power brand of God, basically represents my position, then, what's the next to say?
Oh, that is how to buy second-hand power. That's right. . . that's it. A good power supply, but the price is too abnormal. How can it be broken? Used is the only way out.
Buying second-hand power, my successful example is to buy Antec HCP1000 with 900 pieces. The original price is 2000, and the difference in individual places is basically above 1700. Where are the benefits of second-hand power?
1 Save money
2 Others have used it, which is free to help you test it. Generally, it is better to choose within six months to two years, because the shelf life is also 2 to 3 years, and the shelf life is 2 years, and you choose 1 year or so, 3 years or more. For durability, please select within 2 years. For more than 3 years, there are generally new models. The top power supply, individual protection for 7 years, you are optimistic about slightly, the price has advantages, nor is it not to take. This thing is used by ordinary people. It is used as normal. It won't say 3d games today. It will go to the tester tomorrow. The day after tomorrow it will be downloaded and then standby. It will play 2d games again. In other words, electricity will not fluctuate. Very big, so say, half a year is a watershed, to be repaired, have been repaired, can continue to use, are not how to play overclocking ah, but, brain damage to take 300w to play gtx titan dual sli, Either the power supply burst, or the video card burst, and it will not exist in the secondary market. This is also assured.
3 When you sell it again, you will not feel bad. You think that the new purchase will come to 2000, then sell it will be 1300, or lower, or else everyone else will buy a new one. And you bought it back at 1300 and sold it again, 1,000 or less. The price has an advantage and it will soon be realized.
What are the disadvantages? ? Well, if you use the disadvantages of the power supply, you can summarize it like this:
1 Others used, the interface has friction marks, or the appearance is not good, perfectionists do not like it.
2 Shanzhai, repairs, contractors, OEMs, high imitation, and hard to prevent.
3 bought back, not a few days broken, cry no tears.
4 It is not possible to install the equipment back, or to regret it, or feel that it is not necessary. The problem is to withdraw, but the power supply is good.
5 Without the box packing, it feels old and psychologically uncomfortable.
6 No invoice, warranty, and other reasons can not be guaranteed.
7 The seller shrugs off his bills.
Well, I guess there are other very wonderful reasons. I think so much, then see how to crack the above problem.
1 is the same as 5 . . Here together, some are used, it is brand new to sell, this can ease the mood of perfectionists.
2 This should be done by experienced people. However, Xiaobai, like me, can give you a few tips.
One: General Power Appearance If you are stuck and bruised, I suggest you give it up. These things, 9 Chengdu is a repair, demolition and sale of goods, there are 10% to take a chance, I advise you to forget it, I have seen an Antec 750w hcg, 400, a good deal, but Look at the appearance, there are huge scratches, and then see the seller is a professional selling power supply, I thought, would not be a bad power repair and then sell it? ? ? Later still forget.
Two: To view the seller's transaction records, to see what he is doing, if it is an ordinary user, you can consider if you have sold a lot of power, praise a lot, you have to be careful, oh, minute by brush. Anyway, it is not recommended to sell power with specialization, the price is particularly cheap, and the appearance of JS trading is particularly bad. He said he had a few years of warranty and I was annoying for shipping charges. So forget it.
Three: There are shell packaging, priority, no packaging, generally have a source of problems, do not recommend risk, it is better to choose the shell of the expensive point, after all, to sell later, others also see you this thing.
Four: Some brands of power supply warranty to invoice, then choose the seller of the invoice, some brands recognize sn code, then first call the seller to you sn code, and then you go to the official website or what, what the phone check. Make sure the warranty is valid and start again.
Five: With reference to Jingdong with the paragraph, in the evaluation of the sun bill, there is a picture, you can compare one by one, observe the situation of each screw hole wear, afraid of killing, afraid of being pit. There are warranty void if remove posts are not intact, there is a very bad one, do not.
All of the above is to deal with 2. Next say 3
3 After you return to your second hand, do not hurry to sign for it. The best is SF Express, call courier, etc., and open it in person. Compare the pictures with the real thing. Look carefully for the screws and the quality stickers, the appearance, and the box. This is no problem, we must sign. Because you do not sign, courier will not give you the machine. Then it is the machine, and it will take up to half a day. Then it is always on, and then download the power test software, running voltage, these are no problem, what to do on a daily basis, free fish is 15 days automatic delivery, agreement with the seller is good, there is a test of about 10 days Time, then 10 days, no problem with power, then pay again. This can greatly reduce the adverse outcomes such as being cheated.
4 This is a buyer's problem. Therefore, consider carefully before buying. If you use a second-hand product, do not remorse it. If you buy it, you will immediately resell it.
6 Then pick up the warranty and invoice. . . .
7 transaction records and private chat records to stay, do not come with the seller in any other non-living fish own chat chat price or something, will always refuse to change the seller. No, it is called the second arbitrator.
Well, basically completed, the last point of view, buy power would rather buy 100,200w, do not pinch a precision, this is to protect the use of the machine can be better. Moreover, the greater the power supply as long as your hardware is the same, the same conversion rate of power is not more power.
I hope everyone has to help. The shameless thief loves to turn around. Anyway, I don't care about personal interests. I can see more people and benefit from it.
