Sapphire 584 power
4G platinum version of OC, all aspects are good, the price is 1699, compared with the previous materials, sapphire now shrunk, now the Xunjing rx580
4G black wolf, the price is 1699, but obviously the radiator should give sapphire materials, the core and memory frequency are very high, so it is recommended
More than 500W power supply
the full load power of sapphire rx580 is more than 200 watts, plus the power consumption of CPU and other hardware, it needs more than 500 watts of power
The full load power consumption ofrx580 8g is about 200W, and the power consumption will vary with the core and video memory frequency of different brands and models
500 power supply should also pay attention to whether it is rated power. The rated power value is the rated voltage of the electrical equipment multiplied by the rated current. If the actual power of the graphics card is greater than the rated power, the electrical equipment may be damaged; If the actual power is less than the rated power, the graphics card will not work properly
extended data:
rated power: ambient temperature - 5-50 ℃, input voltage 180v-264v, long-term stable output power of power supply
maximum power: at room temperature, the input voltage is between 200V and 240V, and the output power is stable. The maximum power is generally about 15% higher than the rated power. For example, the new Valley nuclear power plant has a power of 325pq, a rated power of 250W, a maximum power of 280W, close to 300W
peak power: the maximum power that the power supply can achieve in a very short time. The time can only last between a few seconds and 30 seconds. The peak power is related to the operating environment and conditions, not a certain value, but it may be very large and easy to mislead users. For example, the rated power of Xingu 325pq is 250W, and the peak power is 350W. Obviously, only the rated power and maximum power have practical significance
Sapphire rx580 graphics card is better than r9390 graphics card,
the performance of r9390 series is not as strong as rx580,
choose rx580, and the power consumption is lower
the key is whether there are defects
as long as you like the price and think it's reasonable, you can have it.
rx580 4G has 70% higher performance, but it's mostly mine cards,
it takes a long time to use,
it's easy to hang up,
if the warranty is not available or very short, 560 4G will slow down a lot.
so it's better to pay 1700 yuan to buy the new gtx1660 super. You can buy a brand new rx5802048sp 4G graphics card for less than 800 yuan
