- Optimal Gaming Experience. If you are a PC gaming enthusiast you obviously need a PSU to enjoy the service of all your components for long enough. That is one main advantage of having a high-quality PSU. It will always have a positive impact on your system by providing heavy duty protection and providing stable power.
- Prevents Damage to PC. A PSU both protects and prevents your PC architecture from damage. If for example, you are using high-end video cards, a PSU will prevent damage to the application and software in use by providing adequate and stable power.
- Reduces Power Bills. Any 80 Plus Rated PSU plays a very important role in reducing the percentage of power lost to heat. If you are kind that deal with advanced PC gaming SLI architecture and use other components, an efficient PSU will significantly reduce your power bills.

General Thoughts on the Ideal Amount of Power for Gaming PCs
Many gaming PC owners don’t bother to acquire power supplies for their architectural systems and yet they risk losing every inch of their investment. A power supply unit (PSU) plays a great role in supplying a stable and regulated current to the different components in your PC. If for you own an advanced PC gaming system and have expensive graphic cards you better consider having a PSU on your shopping list.
You never know the value of some of these gadgets until a tragedy comes knocking at your door. In any case, a power surge or an electric fault occurs, you risk losing your entire system if you lack a reliable high-quality power supply unit. A power supply may not be such a necessity if you use your PC for home basics but the opposite is true if you have powerful gaming beasts. Buying a power supply is both a smart investment choice and a worthwhile precautionary step.
Since a power supply simply supplies power to your PC components, there are some factors you need to take into consideration when buying one. The most important aspect is to calculate your total power consumption before even thinking about the brand. I know how challenging it can be if you are a novice in this fields. Powering your computer can be mind blowing especially if you allergic to some physics terms. The good news is that the world of computer power supplies has advanced and TDP Calculators are readily available on various websites. You can use them to calculate the power consumption of your system and other components. You don’t have to push yourself so much budget-wise when acquiring a power supply. There are decent units in the market that are great performers yet budget-friendly.
Additionally, it is advisable to go for a brand that is above the 80 Plus Standard. Most PSUs have their maximum efficiency when operating at 50% of the rated capacity. To avoid degrading the performance of your PC chose a PSU whose wattage is above your system requirement so that nominal load range is between 20% and 100%. Avoid operating on the extreme lower or upper rated capacity of your PSU in order to maximize both performance and lifespan. With that said, let me take you through the factors you should have in mind before cashing out for any PSU out there.
Buying a high-quality PSU and especially one that will last for long unfortunately involves a due diligence process. Finding the best doesn’t necessary means that you have to break the bank unless your powering 8 GPUs or something freaky. Despite the fact that expensive is not always synonymous with quality, it is good to avoid opting for the lower end PSUs in a gaming PC build. Many of the PSUs at the lower end are designed for basic home or office computers. In a nutshell, you want to do some research and always keep in mind higher quality components necessitate a more beefy power supply.
The Factors You Should Consider Before Buying Power Supply
A power supply is a very important component that shouldn’t be taken for granted. It determines the long-term reliability and stability of your system. In fact, if you are the kind of folk that just picks whatever meets the eye don’t risk doing so when it comes to buying a PSU, otherwise you risk everything you have been able to buy so far.
A PSU powers and guards your entire system architecture and thus requires much attention. A single mistake made in acquiring a PSU would mean that your system will be prone to crashes, performance problems and boot failures. The following are the factors you should have in mind before cashing out any bucks for a new PSU. Also, if you are building a compact gaming PC, be aware of the dimensions before making final purchases.
The Total Power Consumption of Your Components
This is perhaps the most important consideration that should first hit your mind when you think of buying a PSU. The various components of your PC have different power needs. You, therefore, have to establish the total power needed to support your system without strains. It is always good to consider PSUs whose wattage is above 500, a requirement met by most brands.
However, note that not every PSU whose wattage is above 500 will meet the powering needs of your system. If for example, your SLI architecture uses more than two over-clocked graphics then you better consider a PSU whose wattage is above 1200W for an optimal gaming experience.
In addition, never load your PSU to 100% of its capacity as this may degrade its performance. To be on the safe side, always buy a power supply that is oversized in comparison to the power needs of your system. Having a good margin not only guards your PSU and other components but also allows for future upgrades. There are several calculators on the web that can help you calculate the total power consumption of your system. You, therefore, have to be careful because PC builds differ and the calculators are not 100% reliable.
Fully modular cabling systems not only make handling the cables easier but also enhance the flow of air. With the modular system in place, your entire architecture looks neater and organized. This, however, will depend on personal preference as it is not such a big deal. What is important is to have a PSU whose cabling system is manageable and reduces impedance. Another major advantage of modern modular cabling systems is the connectors that help in using graphic cards and other components.
Efficiency – 80 Plus Standard
PSUs just like any other electrical components are energy efficiency rated by a certification program developed by Ecos. It is what we refer to as the 80 Plus Standard. If a PSU is rated 80 Plus Titanium that simply means that is capable of providing 80% of its rated wattage while the remaining 20% is lost to heat and other energy forms. Well, why do you think you should consider this when buying a PSU? It is because the more efficient a PSU is the less heat it dissipates and thus less power is consumed. If you architecture uses hundreds of Kilowatts you better consider buying a highly-efficient PSU so as to reduce the power bill.
It would be very stressful and disgusting if you spend hundreds of dollars on a PSU only to realize that it is a non-match to your system. Whether you are buying a mid-tier PSU or one that would meet your entire PC gaming power needs, always ensure that it meets all systems’ connection requirements to avoid this mess. If you ignore this factor, you risk buying another PSU or incurring more replacement costs.
Rails and Current Regulations
The rail debate is very controversial in the PSU world. A PSU can either have a single rail or a multi-rail configuration. These are just the connections that deliver different power voltages. A single rail PSU will deliver 12V with the advantage of eliminating the need to balance the loads unlike the case with the multi-rail configuration. The major downside of a single rail PSU is the probability of surging power into the connected components. On the other hand, a multi-rail has the ability to supply power to graphic cards and other components but one has to be cautious when balancing the various power loads. It is advisable to check the current ratings on various PC connections in order to know your standing.
Even though this factor may be an afterthought for many builders, it deserves attention as it can help eliminate serious risks. Most modern PSU has inbuilt heavy duty protection such as Over Temperature Protection(OTP), Over Power protection(OPP) and Under Power Protection(UPP) just to mention a few. These features shut down the system to avoid further damage whenever power irregularities occur. It is good to ensure that your pick has at least one or more inbuilt protection(s).
Last but not list, ensure that you buy your PSU from legitimate retail service providers who provide warranty for their products. No matter how expensive a PSU is, failures can occur when you least expect.
