A power supply’s number one job is to provide enough power for a PC’s components, no matter what type of computer you’re building. But calculating that number takes a bit more math than looking up the TDP (thermal design power) spec for each component, adding up those wattage numbers, and then buying a PSU close to the total. You need more wattage ...
Usually the lower the wattage of a power supply, the fewer power cables it has. Go low enough and this point is a bit moot—generally, systems requiring a 400W or lower PSU just don’t have enough components to needa ton of power cables. Cost also influences the number of cables. Pricier models generally offer more. You have to be most attentive to t...
Power supply efficiency tells you how much actual power you can expect to get from a power supply. While the wattage tells you the theoretical amount provided, the power efficiency rating indicates how much power you should expect to have after losing some to heat and other causes. These days most everything is 80 Plus-rated or higher. At minimum, ...
Modular vs. non modular
Power supplies come in two flavors for how their power cables attach: modular and non-modular. Modular power supplies have completely removable cables, while non-modular PSUs do not. The cables on the latter are installed in a way that is fixed. Predictably, modular power supplies cost more, but they have two advantages over non-modular models. First, you don’t have to plug in all the cables, which reduces how much bulk to deal with in limited space. Second, you can upgrade your PC’s look by...
Form factor and dimensions
The size of your power supply matters for two reasons: It needs to be compatible with your case. And it affects how much physical room you’ll have for the cables attached to it. Make sure to buy an ATX power supply when your case supports only ATX power supplies, and SFX or SFX-L when your small form factor case requires it. When you have a choice, you’ll save money by choosing ATX, but you’ll get more space to work with by choosing SFX or SFX-L. Should you want to reuse the PSU in another bu...
Rails
The rails in a power supply are the individual wires that carry different DC voltages—when the power from your home gets converted from AC, your power supply splits them into 3.3V, 5V, and 12V DC. The components in your PC draw from those rails, with the power-hungry parts like your processor and graphics card reliant on 12V. In the old days, you more often found power supplies with multiple 12V rails. Such a feature allowed you to plug a power-hungry GPU (or multi-GPU setup) into separate ra...
