| Rated Power(Watt) | Working Conditions |
|---|---|
| 300 – 450 | A mainstream CPU + A single GPU |
| 450 – 600 | A CPU + A GPU(overclocking) |
| 600 – 800 | Dual CPUs(overclocking) |
| 800 – 1100 | Top dual GPUs or 3-way GPUs |
| ≥1100 | ≥ 3-way GPUs or dual CPUs + A system with a lot of equipment |
*300-450W
Few people choose this range because it can only meet the power supply requirements of a modern low-power PC with a mainstream CPU and a single GPU. It is not suitable for most gamers and PC enthusiasts.
*450-600W
It is the largest sales volume and the richest product choices in the market.
Even if it is overclocked, the power consumption of a PC composed of a CPU and a GPU will not exceed this range.
*600-800
For gamers with dual GPU systems and those who love overclocking, it is powerful enough and can provide enough surplus sources.
Because surplus sources often make you safe. If you’ve got only one GPU, this level is very suitable for you.
*800-1100
This power range is suitable for high-end two-way or three-way GPU computers.
Whether it is a high-end gaming system or a professional workstation, long-term reliability and stability are absolutely necessary. Usually, the power supply in this range will not be at a low price.
*Above 1100
If you need to use this level of power, it means you have to use a system with at least three high-level GPUs or very powerful dual CPUs and a lot of other equipment.
These power supplies will power some very important functions and quite expensive systems, such as advanced servers and cryptocurrency (such as Bitcoin) mining systems.
Therefore, in this power range, choosing a “value” power supply is a complicated process, because the power supply must meet very high reliability standards.
