The power supply of a computer is equivalent to the heart of the host, supplying blood to those major hardwares. The quality of the power supply will affect whether other components of the entire computer can operate normally. Nowadays, more and more people like DIY computers. They are often more concerned about the parameters of the processor, graphics card, hard disk and memory, and often ignore the power supply. When your gaming PC is assembled with a processor above the i7 level and a discrete graphics card above $300, your computer needs to be powered by a high-power PSU.

What To Consider When Picking The Best 1000W Power Supply?

1. Rated power

The rated power size does not represent the quality of the power supply. However, high-end CPUs and graphics cards are recommended to be paired with a powerful power supply.

2. Power conversion rate

There are many wires on the power supply and there are resistances in the wires. If there is resistance, there will be electrical losses. If there are electrical losses, there will be conversion rates. Generally, you can choose a power supply with 80PLUS bronze certification or above. The rated power refers to the power after removing the power loss, otherwise it is a false standard.

The higher the level, the higher the conversion efficiency and the more power saving. Although it is not positively related to the quality of the power supply, in general most of the power supplies above the gold medal are of good quality. There are two advantages of purchasing a power supply with a high conversion rate: one is that the heat generation is small and the power supply is quiet; the other is power saving.

3. Full modular and non-modular

The cables of the non-modular power supply are not detachable. During the installation process, many cables of the non-modular power supply are redundant. It is difficult to route the cables.

The cables of the fully modular power supply are detachable. You can use any cable to plug in the power supply, and the inside of the chassis will be very clean. You can also buy some custom cables to make your computer more cool.

There are also semi-modular power supplies. The motherboard power cable and CPU power cable of the semi-modular power supply are the same as the non-modular power supply and cannot be disassembled. But the rest of the power cables are detachable like fully modular.

FAQs When Picking The Best 1000W Power Supply

1. How many watts of power does your desktop PC need?

Now the power supplies on the market can be roughly divided into the following ranges: 350W-500W, 500W-900W, and power supplies above 900W. 350W-500W power supply is the most abundant product selection, which can meet the power supply requirements of a desktop computer with a mainstream CPU and single GPU, suitable for office and home use; 500W-800W is very popular among gamers, even for overclocking Or dual GPUs can also provide a large margin; the power range above 900W is suitable for high-end dual- or triple-GPU computers, it can provide reliable power for high-end gaming systems or professional workstations.

2. Fully modular, Semi modular and non-modular power supply, which one should I choose?

At present, the power supplies on the market are mainly divided into modular power supplies and non-modular power supplies, and modular power supplies are further divided into fully modular power supplies and semi-modular power supplies.

The difference between modular power supply and the non-modular power supply is that the modular power supply adopts the separate design of the power supply and the wire cable. When not needed, the wire can be pulled out to save space and increase the heat dissipation capacity. The non-modular power supply directly leads the power cord, these output cables are fixed, so the expansion is relatively poor, and the outlook is relatively cluttered. Non-modular is the most common design and the price is the lowest.

In addition, modular power supply is divided into fully modular and semi modular. All the wires of the fully modular power supply can be freely plugged and unplugged, but the semi modular only supports some pluggable cables. Consider the price, the expansion experience is also good and it can also solve the problem of cable confusion.

So how to choose your PSU? It mainly depends on your needs. If you are targeting a home or office computer, you do not necessarily need a modular power supply. If your requirements are high or you like to DIY, and there is a need for expansion in the future, then you can consider the modular power supply. In addition, modularization is not related to the core performance of the power supply, so there is no need to pursue modularization.

Final thoughts

In general, choosing a computer power supply requires doing your “homework” in advance, and you can’t make a choice just by looking at the brand. You should compare a few more models, you better not choose too low price’s PSU for petty cheap.
