Neither, usually. I think you have your figures somewhat mixed up. The power supply must output at least 18A (amps) on the +12V rail(s) for a mainstream up-to-date computer; more than 24A for a system with a single enthusiast-class graphics card; and this content In case you want to question my Knowlege - Fair to good on computers - But on Electronics, Very well qualified!My credentials are as follows: Have taught circuit analysis and troubleshooting

Worse yet, cheap generic models can literally explode into flames, taking the rest of your computer with it. The Small Form Factor (SFF) designation is used to describe a number of smaller power supplies, such as the SFX12V (SFX stands for Small Form Factor), CFX12V (CFX stands for Compact The Power factor (PF) refers to the ratio of active power (measured in watts) to the apparent power (voltage multiplies current - volts x amps or VA), which includes both active
