Gaming usually uses large amounts of power, more components than a basic desktop, and a 24-pin connector is best for a standard ATX board. In truth the Dual 12v rails are not as critical as they once were because safety is built into most modern PSU but in older models, this was a critical component.


to be fair, an mITX can totally be a high end gaming PC. A lot of SFF computers nowadays can host a 1080ti, etc


A high end gaming pc. Mini-itx was designed for low power consumption builds. High end should give you the impression that a lot of power will be generated from a high end gpu.


According to Comptia's standards, ITX and Mini-ITX is mainly used for industrial business purposes. Gaming does not fall as a primary use for the mini-ITX form factor. Plus, it's "High-End" gaming. It's crucial to notice the details in the key word choices and the environment each question presents.


Then what's the correct answer?


The answer is B,C,F


But isn't there a higher chance of overdraw with a dual rail PSU?




B is a questionable answer. The question doesn't indicate any reason for a large amount of connectors. Answer E seems like an appropriate answer based on the question, especially since F is considered a correct answer.


Actually for high-end gaming 500-550W would be ideal.


A. Mini-ITX C. 24 pin connectors E. 350-450 watts of power
