I looked smallest and powerful videocard for my small pc case(Fractal Design Ridge). This card I found here with very food price. Videocard perfect fit in my pc case. Because this is SFF videocard and dont have evaporation chamber(like have his bigger version), power consumption limit is set to 100%. But it still enough for overclockind. I reduced voltage to 0.925mV and increased GPU to 2850Hz. This card can work with 3000Hz, but in my small case - very fast overheat. If you want build powerful small pc - this videcard will help you!
Best RTX 5070 for a budget. Packs a punch. Thermals are good and fan noise decent. Compare to other brands, Zotac is the low end model, but meets MSRP.
