power calculation formula
power calculation formula:
(CPU TDP power consumption + graphics card GCP power consumption + other hardware power consumption is 50W) / 0.6 = rated power of power supply (unit: W)
note: in the formula, "/" is divided by sign
interpretation of power formula:
we know that in a computer host, CPU and graphics card are two major power consumers in all hardware. The CPU TDP power consumption and graphics card GCP power consumption indicated in the official parameters are not actual power consumption. The actual power consumption will be greater. Take rtx2080ti for example, the design power consumption of GCP is 285w, but the actual power consumption is about 350W, However, we can calculate the TDP power consumption of CPU and GCP power consumption of graphics card. Of course, we divide it by 0.6 in order to retain 40% of the rendant power when it is full load, so please don't worry. Your TDP power consumption and GCP power consumption are not the actual power consumption and other topics
computer host
for other hardware, we can package it with a power consumption of 50W, such as 6W motherboard, 2W memory, 8W single mechanical hard disk, 2W single solid state, and other devices including chassis fan or optical drive
of course, the above power calculation formula is based on independent graphics card. If you are a core graphics card (integrated graphics card), it is enough to use 250w-300w rated power. I suggest starting with 300W rated power. After all, there is not much money for low wattage power. If you consider upgrading graphics card later, it is recommended to reserve power in advance
note: the final power needs to be adjusted according to the actual situation. If you are afraid that it is not enough, you can undoubtedly add another 50W
let's first understand the GCP power consumption of three graphics cards of rtx3070, RTX 3080 and RTX 3090, which are 220W, 320W and 350W respectively. We use several common installation configuration platforms to give an example, as follows< For example:
i7 10700 + rtx3070 host computer, in which i7 10700 TDP power consumption is 65W, rtx3070 GCP power consumption is 220W, other hardware is roughly calculated according to 50W, then (65 + 220 + 50) / 0.6 = 558w, personal recommended rated power is 550-600w, 600W stable enough, including sure enough, If it's not enough, of course, it can also be directly on 650W
i7 10700k + rtx3070 computer host, in which i7-10700k TDP power consumption is 125w, rtx3070 GCP power consumption is 220W, other hardware is roughly calculated according to 50W, then (125 + 220 + 50) / 0.6 = 658w, the recommended rated power is 650-700w, if the usual toss over frequency, the recommended rated power is 750W
i9 10900k + rtx3070 computer host, in which i9-10900k TDP power consumption is 125w, rtx3070 GCP power consumption is 220W, other hardware is roughly calculated according to 50W, then (125 + 220 + 50) / 0.6 = 658w, the recommended rated power is 650-700w, if the usual toss overclocking, the recommended rated power is 750W
i7 10700k + rtx3080 computer host, in which i7-10700k TDP power consumption is 125w, rtx3080 GCP power consumption is 320W, other hardware is roughly calculated according to 50W, then (125 + 320 + 50) / 0.6 = 825W, the recommended rated power is 850W< The power consumption of i9-10900k TDP and rtx3080 GCP is 125w and 320W respectively, and other hardware is calculated as 50W, which is (125 + 320 + 50) / 0.6 = 825W, and the recommended rated power is 850W
i9 10900k + rtx3090 computer host, in which i9-10900k TDP power consumption is 125w, rtx3090 GCP power consumption is 350W, other hardware is roughly calculated according to 50W, then (125 + 350 + 50) / 0.6 = 866w, because there is no 900w-950w power supply in the market, the recommended rated power is 1000W
summary:
the above is the power calculation formula shared by it network, roughly calculating the overall power consumption of rtx30 Series graphics card. If you are going to start with rtx30 Series graphics card, you don't know how many watts of power you need,
On September 28, 2019, Gigabyte launched two RTX 3080 Series graphics cards after the first two geforce rtx3080 gaming OC 10g Falcon and geforce RTX 3080 Eagle OC 10g falcon, which are respectively the super carvings of aorus geforce RTX 3080 master-10gd, And geforce RTX 3080 vision oc-10gd snow eagle
as of October 25, 2020, these are the latest series of graphics cards, and the configuration is also the top
extended information :
the new cards all adopt the forward and reverse cooling system of three fans, two 90mm and one 80mm special blade fans, and are equipped with seven high-performance pure copper heat pipes As well as fan intelligent start stop and other heat dissipation technology and air intake grille and other heat dissipation technology, can greatly improve the heat dissipation effect, enhance the stability and life of the graphics card
the fan uses nano graphene lubricating oil, which has longer service life and quieter performance. In addition, the intake grid heat dissipation design, large copper plate and composite heat pipe heat dissipation technology are the ultimate stacking practices. In addition, the ultra rable power supply design further improves the performance, stability and overclocking potential. RGB fusion 2.0 and modeling metal reinforced backplane are essential
1. Different resolution: at 2K resolution, rtx3080 is 25% higher than rtx2080ti
2. Performance difference: rtx3080 shows performance on compubench, and the running score is much higher than rtx2080. It can be seen from the comparison results of each sub item that the performance of rtx3080 is twice as high as that of rtx2080 and about 60% higher than that of rtx2080, and the improvement is still obvious
Different frequency of video memory: 19000mhz for 2080ti and 14000mhz for rtx3080
extended materials:
precautions:
if there is a strong demand for computer display performance, rtx30 Series graphics card is worth buying. NVIDIA ampere architecture is based on Samsung 8nm
The NVIDIA ampere architecture doubles the throughput of light and triangle crossing, and the RT core reaches 58rttflops and Turing 34rttflops. Meguiar's gddr6x video memory is also used The power consumption of
rtx30 Series graphics card is greatly increased, reaching more than 300W, which means higher requirements for power supply. Generally speaking, power consumption = graphics card power consumption + CPU power consumption + other hardware power consumption (60w-120w, depending on the number and total power consumption of other hardware, note that TDP is not equal to power consumption.)
because Buffett himself does not support bitcoin, he always thinks that bitcoin is a fraud
for a veteran investor like Warren Buffett, Warren Buffett has always believed in value investment, that is, he is optimistic about the performance of an enterprise for a long time, while bitcoin has no physical support, which means that bitcoin is a kind of hype
Buffett never talks about bitcoin
Buffett holds his own shareholders' meeting every year. At this year's shareholders' meeting, he never talks about bitcoin, and when reporters repeatedly ask about bitcoin, he is always reluctant to give a positive reply< this is not the case once or twice. In a rare conversation with Warren Buffett, we can see that he is very pessimistic about bitcoin . The reason is also very simple, because Buffett always thinks that bitcoin is a fraud{ RRRRR}
he can move back and forth
hope to adopt*-*
