Nvidia Geforce RTX 5090, recently released on the market, has drawn attention not only for its robust performance but also for its energy demand. Recent tests revealed that the plate is reduced by approximately 5% in performance when fed by a 3x 8 -pin adapter instead of the recommended 4x 8 pins.
Drop in performance when reducing food
According to analyzes conducted by the Computerbase Portal, the RTX 5090 was tested with different power settings, including 575W, 450W and 400W TDP.
Nvidia has allowed the plate to work with lower power supply to avoid compatibility problems. However, this is accompanied by a loss of performance that can be significant for those seeking the maximum of the GPU
The main finding was that by providing 100W less than ideal, performance in ratering tests suffered a noticeable drop. Interestingly, the GPU was still able to operate with 3x 8 pins, but has become incompatible with only 2x 8 pins, indicating that a supply below 300W is not feasible for this model.
The recommendation to use the 4x 8 pins aims to ensure that GPU receives up to 600W, which is essential for robust variants, such as Rog Astral GeForce RTX 5090, known for its high energy consumption.
Inventory and performance questions of the Blackwell line
The release of the new Nvidia GPUs has been marked by some challenges. In addition to concerns about correct food, there are reports of RTX 5090 units being unusable by possible flaws related to BIOS, drivers or even the PCIE connection. The scenario reinforces the need for attentive follow -up by consumers to avoid unexpected problems.
Another point that impacts users is the availability of these plates on the market. Recently, Nvidia itself has recognized that the RTX 5080 and 5090 stocks may not be enough to meet high demand, which may influence access to these GPUs in the short term.
This adds to the mixed reception of RTX 5080, which, according to analyzes, performs only 8.3% higher than RTX 4080 super on average.
