10 best computer power supplies
Computer Power Supplies:
A computer power supply, often referred to as a PSU (Power Supply Unit), is a critical internal component of a computer that provides electrical power to all other components. It converts electricity from your wall outlet into a form that can be used by your computer's internal components.
Key Features and Components:
Wattage: Power supplies come in various wattage ratings, typically ranging from 300W to 1000W or more. The wattage you need depends on your computer's components. High-end gaming rigs or workstations require higher wattage, while basic office PCs can make do with lower wattage PSUs.
Connectors: Power supplies come with various connectors to power different components within the computer, including motherboard connectors (e.g., 24-pin ATX), CPU connectors (e.g., 4-pin or 8-pin CPU power), and connectors for peripheral devices (e.g., SATA, PCIe).
Efficiency Rating: PSUs are rated for efficiency using the 80 PLUS certification system, which includes Bronze, Silver, Gold, Platinum, and Titanium ratings. Higher-rated PSUs are more energy-efficient and generate less heat.
Modular vs. Non-Modular: Power supplies can be modular or non-modular. Modular PSUs allow you to detach unused cables, making cable management easier and improving airflow within the computer case.
Overcurrent and Overvoltage Protection: Good power supplies have built-in protection mechanisms to prevent damage to your components in case of power spikes or surges.
Form Factors: Power supplies come in different physical sizes or form factors, such as ATX, SFX, and TFX.Ensure your power supply matches your case's form factor.
Cooling: Many PSUs have fans for cooling. The size and quality of the fan can affect noise levels. Some high-end PSUs have fanless designs for silent operation.
Importance: A reliable power supply is crucial for stable and safe computer operation. If your PSU is inadequate or fails, it can cause system instability, crashes, or even damage to your other components. Investing in a quality power supply is essential for the long-term health and performance of your computer.
Upgrading or Replacing: If you're upgrading your computer's components, especially the graphics card or CPU, you may need to upgrade your power supply to meet the increased power demands. When replacing a PSU, make sure to choose one with the appropriate wattage, connectors, and efficiency rating for your needs.
In conclusion, a computer power supply is a critical component that provides electrical power to all other components within a computer. Choosing the right PSU based on wattage, efficiency, connectors, and other factors is essential for reliable and efficient computer operation.

User questions & answers
Question: | Every time my ups (i've tested on three) shifts to battery (or from battery) this cycles off then on, forcing restart. any ideas why |
Answer: | you are having a power surge somewhere. either the UPS cant meet the load when it transitions or the UPS is faulty is my guess. |
Question: | does this come with triple 8 pin or do i need to buy another cable |
Answer: | Do not get this power supply for a 3080+. Unless something has changed in the last couple months. It would not reliably power my 3080 |
Question: | Funciona con 220volts como se ve en la foto |
Answer: | Si, 220 Vac ... Trabaja muy bien, en relación precio potencia está muy económica, muy buen sistema de protección. Saludos cordiales desde Chile. |
Question: | Is this ga model an sfx or sfx-l size |
Answer: | it is neither. It is a regular size PSU. The 1200Watt models are often slightly longer but still called a regular power supply. This is a spec sized for an ATX chassis. Perfect for an OEM brand PC that might not give any excess room for the longer 1200 watt power supplies. |

User questions & answers
Question: | DEAD-ON-ARRIVAL: is there an indicator besides the I/O switch to determine if PSU is ON or OFF? My old PSU had an LED that lit up if PSU was working |
Answer: | It is semi modular. Semi modular means that that necessary plugs are not removable, but the optional ones for hdds, psu, etc come removable. |
Question: | does this have the 8 pin 12v cable |
Answer: | Polyphenols are naturally occurring in the plants included in the Superfood Reds & Greens. Polyphenols are phytochemicals, which are naturally occurring compounds that give plants their colors or help to protect them from various dangers they might face in nature. polyphenols typically act as antioxidants, which means they can help prevent cellular damage from free-radicals that occur with pollution, smoking, eating rancid foods, and as a byproduct of normal metabolism. It's also thought that polyphenols contribute to the body being in an anti-inflammatory state, which is also associated with a lower risk of several chronic diseases. Several polyphenols, such as quercetin, catechins, lignans, resveratrol, and curcumin, are touted as being anti-inflammatory agents. Because this is a whole food product the Polyphenols are not listed in supplements facts panel but occur naturally in the product with all the cofactors needed by the body such as vitamins, minerals, antioxidants, fiber, etc. I hope this makes sense. No product actually lists the polyphenols in the supp facts panel. Thanks, T. |
Question: | How long are the primary cables? Need to reach around a large video card in a big case |
Answer: | Yes, we use plant derived Stevia. We do have a non Stevia version but it is not on Amazon yet. |
Question: | Is this modular? At the top it reads semi-modular and below it reads modular,, which is it and what is the difference |
Answer: | barely can taste the Stevia |

User questions & answers
Question: | Are the cables braided? if so, are they white or do i need to custom order some individually white sleeved cables? thanks |

Question: | Does is come with a sata power cable |
Answer: | 1=on and 0=off on the power supplies master switch sure jumping the green (on/off control wire) to black (ground) will turn on the power supply. |
Question: | Does the power supply have 6 sata cable ports |
Answer: | To clear things up, I have the 600 watt version of this. And yes it does have a 8 pin 12v cable |
Question: | What's the difference between the corsair rmx series and the rmi series? for example the corsair rm750i and the corsair rm750x |
Answer: | Joe, it's been a few months since I assembled my system but, as I recall, the cable lengths were all very generous. I don't think this should be a problem for you with this PSU. A big plus is all the variety of cables and connectors that are included with this unit. Very versatile package that was highly recommended to me by a serious "techie" at Tiger Direct. I took his advice but made my purchase here. |

Answer: | They will be releasing one for it soon. |
Question: | How quiet is it (noisy fan |
Answer: | Every holster is gun specific. Part of the order process is advising them the make/model of gun you with use the holster for. |
Question: | how about the warranty |
Answer: | Yes |
Question: | Does it have cables to connect to a cd/dvd burners |
Answer: | This will not work for either way. It has a strap for your ankle that the finger from the holster sits in so it doesn't slid down. You could just let the finger sit inside the top of your boot at the top but that would probably stab you over time. You could probably get the strap tight enough to have it stay on the book, but it might make it harder to draw your weapon. |
