Maximum power consumption by a single GPU

[Harry-Son]

From the past one year, I have been using a Dell optiplex Desktop computer which previously came with a 265w power efficient psu. Right now I am thinking about installing a new Graphics card in it but I have doubt about whether my Current power supply is enough to power up the GPU or not. I have heard that GPU need sufficient amount of power supply and during the game play it drain more from the PSU. Can anyone tell me what the maximum power consumption of gpu is?

After analyzing both NVidia cards and ATI cards, it seems that NVidia leading in energy consumption, where even the Geforce 7800 GTX 512MB reaches the consumer 100W the maximum, while the X1900XTX can reach 120W. In all cases, complain that the upper range of cards are too noisy, and this time, too long, so we must be careful when choosing our model, to ensure that we have no space problems in our computer. A good guide to decide which is the most balanced that we can agree best for your computer, regardless of the segment that we seek.

Some new models of graphics cards for mini PCs are characterized by high energy consumption. However, with the finest engravings GPU, graphics cards have midrange power consumption low. Similarly, the heat is reduced although the cards are performing. The graphics card must be compatible with the power supply system and the mini PC. The power supply is indicated by the words "High Output". Models of graphics cards are supplied with a voltage of 12V. Therefore, it is necessary to determine the maximum power that the power is able to provide on this line voltage. To do this, simply check the table on the label of the PC power supply. Then, it is necessary to refer to the current value equal to 12V. The value that is included will then be multiplied by 12 to determine the value of the maximum power. Therefore, if the intensity equivalent to 12V is 14 A, maximum power is 168W. The configuration must be less than 168W.

The consumption of GPUs is the question of the power supply, which should provide stable energy; otherwise it would compromise the same operating system. In the worst cases can damage the power supply itself. It's good to know, then, that power will be needed, as well as adapters and connectors will be used. Last but not least, we must consider the costs, both those components as those of energy, which in general are considered on an annual basis. Taking into account all these factors, we have packed this guide should help you find the right balance between performance and energy costs, with due awareness.

Graphics can sometimes consume more power than an entire PC system. Some high-end cards for gamers or professional users can be accommodated with a TDP (thermal design power, the entry for consumption under full load) greater than 300 watts under full load on the market and this consumption is in fact often exceeded. This phenomenon has recognized by expert testers and it has been found among other older ATI and Nvidia gaming boards. For the mainstream office applications, AMD recommends the Radeon HD 5570th this is with 8.6 watts (idle), 31.6 watts (load game) and 37.3 watts (full load) power consumption very well in class rank, although some GeForce G210 cards are sometimes even more economical. Be seen under load (15 watts) and full load (16.2 watts) may also involve an "Asus EAH 4350 Silent". The "Green Edition GeForce 9600 GT" In addition, Nvidia has the maximum power of 96 watts almost halved to 59.

These data do not need to be taken as being accurate, but as guidance only. Each model may have different variations because such manufacturers distribute the same models with different frequencies, or eventually improve the manufacturing process of a same chip, etc.

The PCIe graphics consume practically all of the 12V line of the source. Dividing the consumption shown in Table 12 to leave the amps need about the chart on 12V line.
