Everything About Power Supplies
Introduction
Welcome to my comprehensive guide on power supplies! This video is not sponsored by any company or product; everything shared here is based on my personal experience and research. If you need a ballpark wattage calculator, feel free to visit Seasonic's Wattage Calculator.
What is a Power Supply Unit (PSU)?
A Power Supply Unit (PSU) is a critical component in a computer that converts electrical power from an outlet into a usable form for the computer's internal components. It ensures your system gets the right amount of power, distributes it correctly, and provides stable and reliable power to the motherboard, CPU, GPU, drives, and other peripherals.
Key Components and Specifications
Wattage
Definition: The total power output a PSU can provide, measured in watts (W).
Importance: Determines how much power your PSU can supply to your components. Higher-end systems with powerful GPUs and CPUs require higher wattage.
Efficiency Ratings
80 PLUS Certification: Indicates the efficiency of the PSU. Ratings include 80 PLUS, Bronze, Silver, Gold, Platinum, and Titanium.
Efficiency Impact: Higher efficiency means less power waste as heat, better energy savings, and often a longer lifespan for the PSU.
Form Factors
ATX: Standard size for most desktop computers.
SFX: Smaller form factor for compact or small form factor (SFF) builds.
Others: TFX, Flex-ATX, etc., for specialized or smaller cases.
Connectors
24-Pin ATX Connector: Main power connector for the motherboard.
8/4-Pin EPS Connector: Provides power to the CPU.
PCIe Connectors: 6-pin, 8-pin, and combinations (e.g., 6+2) for graphics cards.
SATA Connectors: Power for SSDs, HDDs, and optical drives.
Molex Connectors: Older power connectors for peripherals like fans and some drives.
Modularity
Non-Modular: All cables are permanently attached.
Semi-Modular: Essential cables are attached, optional ones are modular.
Fully Modular: All cables can be attached or detached as needed.
Protections
OVP (Over Voltage Protection)
UVP (Under Voltage Protection)
OCP (Over Current Protection)
OPP (Over Power Protection)
SCP (Short Circuit Protection)
OTP (Over Temperature Protection)
Cooling
Fans: Size and quality of the fan impact cooling performance and noise levels.
Fanless: Some PSUs are designed to operate without a fan, ideal for silent builds.
Rails
Single Rail: Provides all power through one high-capacity rail.
Multi Rail: Distributes power across multiple rails, which can enhance safety.
Choosing the Right PSU
Selecting the appropriate PSU depends on your system's power requirements and future upgrade plans. Use a wattage calculator like Seasonic's Wattage Calculator to estimate your needs.
Conclusion
Understanding the components and specifications of a PSU is crucial for building a reliable and efficient computer system. Remember, this guide is based on personal experience and research, without any sponsorship or endorsement. Choose wisely and ensure your PSU meets your system's demands for the best performance and longevity.
Thank you for watching, and happy building!

nice vid!:)

Thank you!

My 560watt 80plus seasonic. About 12 to 13 years old running with no issues because i speeded the few extra bucks back in the day

Amazingly good Power supplies...

[@alf8718]

Really? I haven't seen 1 fan using more than 10 W, usually it's less (5W). You want to buy too powerful PSU, be my guest, but don't mislead people that don't know much about those things. You exagerate with everything here (apart from GPU). And what works for You, does not necessary work for most of the people. (10 fans)

[@BudgetTechUKYT]

This is not misleading. If it's worth doing it's worth overdoing. Never cheap out on a power supply. I also clearly mentioned in the video that my PC is special with 10 fans. If your logic can't accommodate what I'm saying or trying to teach you, it's not misleading, it's then lack of understanding.

[@BudgetTechUKYT]

As a rule of thumb Total watt + 20% extra. Not sure if you know this, but it's standard practice.

[@alf8718]

@@BudgetTechUKYT Of course, but 20% more or maybe even 30% more just in case, except this "extra" power should be calculated on the ACCURATE power calculation - not like You do, for example You give Your CPU 150 W, if you happen to have a decent processor it may be 120 W (like at the moment very popular Ryzen 7 7800x3D), and many "gaming" processors go even lower (under 100 W, all the overclocking included) and more accurate calculation will give You substantially lower cumulative Power needed, and THEN only add 20%! Or 30% but surely no need for a 1000 W PSU unless You have a build with 600+ W graphics card. The Quality of the PSU is more important than the extra power! Don't underspend on PSU, but no reason to OVERspend on it as well, I've noticed You have a magic word "Budget" in Your channel name 🙂

@@BudgetTechUKYT Oh, Yesterday I responded to Your other response to my comment, did't notice this one. What an arrogant and ingnorant little person You are. You are trying to teach me something - You don't even know me, I was trying to be positive, just pointed out on Your false claims. You've got a looooooooot to learn son to be able to teach me anything. And again, 10 fans is NEVER 150 W, most of the normal fans You buy (120 mm or 140 mm) are in range from 2 to 6 W per unit. Poor little offended child, nobody should say anything against Your false narrative or You'll start crying and calling people names for daring to do so.
