Three focused calculators, each with transparent math and cited assumptions. Pick one to get started.
PSU Wattage Calculator
Size your power supply with honest headroom math.
Pick your CPU and GPU (or enter wattages manually), add your accessories, and get a recommended PSU wattage with transparent assumptions — minimum, comfortable, and the retail tier to buy.
Open toolMonitor PPI Calculator
Pixel density, pixel pitch, and viewing distance.
Enter screen size and resolution to get PPI, pixel pitch in millimeters, the retina viewing distance, and a comfortable distance range — plus what the density means for office work, gaming, and design.
Open toolGPU Power Connector Checker
Which power cables your graphics card needs.
Select a GPU to see its power connector requirement, estimated board power, a recommended PSU range, whether an ATX 3.x unit makes sense, and the cable safety notes that actually matter.
