Power supplies are a frequently misunderstood--and overlooked--PC component. Many users choose a power supply based on total wattage alone, assuming that higher is always synonymous with better. Others pay no attention to their PSU selection at all, and settle for whatever abomination arrived with their machine. But considering how important a good power supply is to a system's stability and long-term reliability, it's a shame that PSUs get so little attention in comparison to sexier components like graphics cards and SSDs.

The simplest way to make your PC games look better is to buy a better graphics card. If you already have the best graphics card money can buy (one of these, perhaps), the next step is to install a duplicate and make them work together. Most savvy PC users have a machine with a discrete graphics card, but adding a second or even third card and running them together can lead to a big performance boost in demanding PC games.
