Common Questions

What’s Wattage

First off is the term Wattage which refers to the amount of electricity (in watts) that a particular component can consume.

What’s Amperage

The term Amperage represents the maximum current rate that a device can draw from the power supply unit.

What’s Voltage

Voltage is the measure of electrical potential difference between two points. The higher the voltage, the more powerful and better the performance. However, a higher voltage also means greater amounts of heat and energy consumption.


In general, when choosing a PSU for your RX 570, it’s best to use a PSU with 450W or higher if you have a powerful GPU/CPU Combo.


Importance of a Good PSU


A proper PSU is essential for every computer setup because it plays a key role in supplying ample amounts of power to every single part inside your PC. A bad PSU would cause severe damage to the motherboard, causing frequent crashes and even blue screens. Most people tend to think that they don’t need anything beyond 500W since most modern computers require only that much anyway. But there are exceptions.

It’s worth noting that there are many factors that affect the actual wattage usage. Some parts draw more power than others, and a few parts may need more voltage than others too. Also, some components produce more waste heat during operation than others. For example, an RTX 2070 draws more power than an R9 380. Therefore, if you want to save money, it’s very important to know what kind of hardware you have installed on your PC. That way, you’ll know what wattage you need to purchase.
As a rule of thumb, try to stick within the range of 200-700W for desktop builds depending on your CPU / GPU and 300-500W for laptops. Of course, it depends on your specific case. If you’re unsure, don’t worry! There are plenty of great tools out there that help you estimate the exact wattage you need. One of my favorite apps is called Cooler Master TPC Pro Utility, which lets you select individual components and estimate the total wattage needed.

What’s 80+ Gold

Another thing that you should consider when looking for a new PSU is the 80+ certification label. Basically, it’s a rating scheme that ensures manufacturers meet certain quality standards. The main goal behind this program is to offer consumers peace of mind that they won’t receive faulty products.

To earn the 80+ standard, a company must pass several tests. These tests consist of continuous load testing, short circuit protection, surge protection, ripple control, and noise emissions. Once passed, the company gets an official seal that says 80+. Products with this mark are generally known to be reliable and safe to use. Even though there aren’t any hard rules, companies who participate in the 80+ gold program typically manufacture top-notch units that last a long time.

Some notable vendors that carry 80+ Gold status are Corsair, EVGA, NZXT, ASUS, MSI, XFX, Patriot, Thermaltake, HyperX, Seasonic, and Corsair.


Final Thoughts

Buying a new PC isn’t easy. When purchasing a new GPU like the RX 570, it’s especially difficult. After all, you have to take into consideration everything from price, power requirements, and compatibility issues. Fortunately, buying a good PSU is relatively straightforward. Just follow our guidelines above and you’ll never have to worry about it again.
