Are you in the market for a new PC power supply unit (PSU)?  <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

If so, you\u2019ve likely come across classifications like modular, semi-modular, and fixed. But what do these terms mean, and what extra considerations should a prospective buyer take into account? In this guide, we\u2019ll explain modular PSUs, from how they differ from other power supply units to whether they\u2019re the optimal choice for your next PC build or upgrade.  <\/p>\n\n\n\n

\n\n\n\n

What is a Modular PSU? <\/h2>\n\n\n\n

Modular power supply units give you greater control over cable management inside your computer. The more modular your PSU, the easier it is to plan precise cable routes<\/a> that improve airflow<\/a> and create a cleaner, more professional-looking PC. <\/p>\n\n\n\n

What\u2019s more, modular PSUs can also be compatible with a wide range of custom cable kits and individually sleeved cables, making it easier to personalise your computer’s appearance. However, we recommend checking that the custom cable kit you’re interested in is compatible with your PSU model. Some power supplies feature different pinout configurations, and using incompatible cables can leave you in a bind or even damage components.  <\/p>\n\n\n\n

Modularity is a spectrum, rather than just being a straightforward yes\/no feature. Power supplies are typically available in three configurations: fully modular, semi-modular, and non-modular (often called fixed) designs. Each approach delivers its own balance of convenience, cable management flexibility, and installation complexity. The more modular the component, the more you can expect costs to trend upwards, too. <\/p>\n\n\n\n

As a result, knowing the differences between these classifications can help you choose a PSU that best suits your budget, build requirements, and aesthetic preferences. <\/p>\n\n\n\n

Fully Modular PSUs <\/h3>\n\n\n\n

Every cable on a fully modular PSU can be detached and swapped out. As a result, you get the added flexibility of only connecting the cables your configuration requires. No leftovers! <\/p>\n\n\n\n

Without unnecessary clutter, managing your remaining cables is a far easier and more streamlined process. The door is also open to utilising customised cable kits without negating the warranty on your PSU. Once again, double-check that the one you\u2019re interested in is compatible with your unit’s pinout configuration.  <\/p>\n\n\n\n

Of course, the more agency you have, the more you can expect to pay for that privilege! Fully modular PSUs are pricier, but absolutely worthwhile if you\u2019ve got the dough.  <\/p>\n\n\n\n

Does a Fully Modular PSU Improve Performance? <\/h4>\n\n\n\n

Generally speaking, modularity alone does not improve gaming performance or system speed. The main benefits are improved cable management, cleaner aesthetics<\/a>, and an easier time upgrading your configuration<\/a>.  <\/p>\n\n\n\n

Of course, optimised airflow can indirectly improve some aspects of your gaming computer\u2019s performance. Your hardware may also last longer if it\u2019s not frequently overheating <\/a>and throttling. That said, your cooling solution<\/a> will be doing the bulk of the heavy lifting there. <\/p>\n\n\n\n

When it comes to gaming performance, a PSU\u2019s wattage<\/a>, 80 PLUS efficiency rating<\/a>, and proven track record in testing<\/a> are far more important considerations than whether its cables are modular. The quest for modularity is worthwhile, but don\u2019t lose sight of these key metrics!  <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Semi Modular PSUs <\/h3>\n\n\n\n

As the name suggests, semi modular PSUs take a bit from column A and a smidgen from column B. That is to say, only some of the cables are detachable! <\/p>\n\n\n\n

Which cables are fixed depends on the model that you buy. It might be that you\u2019re dealing with ATX 24-pin and EPS12V 8-pin connectors at a minimum. You may also find an 8-pin PCIe cable is locked into place.  <\/p>\n\n\n\n

At the very least, though, you still have some say in how to manage those cables! Just not as much as if you were to have full modularity… <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Fixed PSUs <\/h3>\n\n\n\n

Fixed PSUs are sometimes referred to as non-modular PSUs or regular PSUs. Whichever way you slice it, you can\u2019t detach any of their cables.  <\/p>\n\n\n\n

As such, what you see is pretty much what you get. They can be a bit of a faff to deal with, as cable management becomes a puzzling chore (you may even be lumbered with cables you don\u2019t need for your spec), and there can be some restrictions around the cases you can use with them.  <\/p>\n\n\n\n

The good news, however, is that fixed PSUs are very affordable. That said, unless you\u2019re going for an exceedingly entry-level spec (nothing wrong with that!), you\u2019re unlikely to encounter them.  <\/p>\n\n\n\n

\n\n\n\n

Is a Modular PSU Worth It? <\/h2>\n\n\n\n

Our determination is that, yes, a modular PSU is worthwhile. Whether yours is fully or semi-modular is up to you. It all depends on your computer build requirements and your budget.  <\/p>\n\n\n\n

More freedom is always a good thing, as is removing any extra cables that you aren\u2019t using. Ultimately, we\u2019ll always endorse any component or configuration that makes your life as a PC gamer easier!  <\/p>\n\n\n\n
