Power supply units (PSU) are an integral part of your computer. For PC components to run effectively they need a power source that can consistently match their demands. The PSU is what supplies your entire PC with the power it needs to run efficiently. Because of the important role that a PSU plays in powering your system you’ll want to get a unit that is powerful, quiet, and efficient. In today’s blog we’ll talk about what a PSU does, what to look for in a PSU, and the advantages of the EVGA PSUs that are coming soon to Best Buy.
What does the power supply do?
If the central processing unit (CPU) is the brain of your computer then the PSU would be your computer’s stomach. The job of your stomach is to take in food and convert it to a form of energy that can be used by your body. Like your stomach the PSU converts your electrical outlet’s alternating current (AC) into direct current (DC) which can then be used by your PC. In order to deliver power, PSUs have dedicated cables with specific connections for each PC component such as the graphics card, storage, and motherboard.
Introducing EVGA SuperNOVA 750GT and 850GT power supplies
There are two EVGA PSU models coming soon to Best Buy. These models are the 750 watt EVGA SuperNOVA 750GT and the 850 watt EVGA SuperNOVA 850GT. Both PSUs pack serious specs making them strong contenders for anyone looking to upgrade.
80 Plus gold certification
All power supplies from major manufacturers go through a power efficiency certification process. The 80 Plus certification means that a PSU has a minimum of 80% power efficiency. Next, PSUs are also classified as bronze, silver, gold, platinum, or titanium. A bronze classification means the PSU has a base power efficiency of 80% while titanium classification means a 92% power efficiency. The EVGA SuperNOVAs are classified as gold meaning they have a 87% power efficiency rating.
Fully modular design 
Both EVGA SuperNOVA PSUs have fully modular designs. This is the choice design for gamers and PC builders. Modular PSUs give you the flexibility of attaching or detaching power cables based on your PC component needs. The benefit is that it keeps the number of cables to a minimum, meaning less clutter and improved air flow with the PC case.Â
Fluid dynamic bearing fansÂ
Fluid dynamic bearing (FDB) fans are almost completely silent and have the longest life span of any fans. FDB fans have no axial preference and can be mounted in any direction without suffering from wear or fluid leak. Finally, FDB fans are capable of pushing more air than similar fans in their class. This is important as fans keep the PSU cool while under heavy loads.Â
Auto eco modeÂ
This mode adjusts the fan speed based on the temperature of the PSU. During times of low energy use the PSU will become cooler and the fans will slow down or shut off. This results in less noise and lower power consumption.
7 year warranty
While other PC components may have a 1 to 5 year warranty, the EVGA SuperNOVAs come with a 7 year limited warranty. This long warranty ensures that any manufacturer-related defects in your PSU are covered. To activate your warranty, register your PSU and upload your proof of purchase to the EVGA website.
The EVGA SuperNOVA 750GT and EVGA SuperNOVA 850GT will be arriving between late May and June 2021. In the meantime, if you’re considering upgrading PC parts or are looking to build a new computer be sure to check out Best Buy’s full selection of PC components.
