Ensuring a PSU is efficient, can supply enough power, and is reliable is a balancing game PC builders have to play, while still factoring in how much budget they have. The best power supply for one user might not be appropriate for another. Fortunately, we’ve put together a list of PSUs that should help most PC builders find the right product. For those looking for a clean, photogenic build, the RM850x is fully modular and is compatible with Corsair’s sleeved cables. It also can use a USB 2.0 header to allow for software control through Corsair’s iCUE control panel. This enables users to control a host of settings, including the fan curve. At under $150 MSRP, the RM850x is priced to move, and the extra features and quality are worth the premium, compared to more basic PSUs. The Grand RGB is a fully modular PSU, which makes for an easier, better-looking build. Sleeved cables are also available (at extra cost), which allow for that extra touch of sophistication. The only thing putting this product below the RM850x on our list is that it lacks decent over-temperature protection. Either the feature is missing entirely or the OTP shutoff is set so high that it’s ineffective. If the PSU ever reached a temperature that would damage the hardware, another set of sensors would likely detect a fault and shut down the PC. However, when dealing with a PC that likely cost thousands of dollars, most users want all the safeguards they can get. This PSU also only technically outputs 800 Watts. In actuality, its max output wattage is 720W on the 12V rail and 130W on the 3V and 5V rails. This means users should take care to calculate their power needs before purchasing the GM-800 carefully. The only real frills with this unit is that it’s semi-modular, so keep in mind that a budget PSU should go in a budget build. The biggest drawback of the C750 is that it can be a bit loud. It’s an 80+ Gold certified PSU and features a Zero RPM Fan Mode. However, its 120mm fan is noisier than similarly equipped PSUs. Those who picked up an RTX 3090 might also find 750 watts a bit too anemic, in which case the C850 would be a better choice. However, most single CPU/GPU users will find 750W to be adequate. The majority of PC builders should find the best power supply for them in the list above. However, there are some scenarios where a user needs more wattage than the units above can provide. Fortunately, many of the products above have variations that output more wattage. These are more expensive but still, have the same great features.
