EVGA Supernova 850 G5 80 Plus Gold 850W Fully Modular Power Supply - ECO Mode with FDB Fan, 10 Year Warranty, Compact 150mm Size (220-G5-0850-X1) - Perfect for Gaming PCs, Workstations, and High-Performance Computer Builds

This EVGA power supply (PSU) is the best of the best. Not only for my use case is it more than overkill it also has phenomenal build quality, runs extremely quiet, and comes with tons of extra cables.I am using this in my latest home server build. It is powering my i5-7500 on an Asus Z270-G mATX motherboard, and 4 Seagate Ironwolf Pro 8TB 7200rpm hard drives. 550w is definitely more than I need but as this server can run for a week straight it was important to me to get a high quality and efficient PSU. Typically anything under 550w from most brands steps down a tier level when it comes to build quality, so this seemed to be the clear choice. This is also my third EVGA PSU and all have been running flawlessly. My 750 P2 is coming up on 2 years old and it has never missed a beat. So I knew this PSU would live up to my expectations.Also, it is worth mentioning that this is a Tier 1 PSU, if you don’t know what PSU’s fall under a what tier level it is best to look it up. Basically, tier levels 1-5 tell you how well a PSU is made. 1 being the best quality PSU’s, and 5 being the worst. People often associate wattage and efficiency levels with how good a PSU is when that is in fact not true. A 1000w 80+ Gold or 80+ Platinum efficiency PSU can be made with cheap components that do not last. Many Gold and Platinum PSU’s are not classified as Tier 1 or even 2 PSU’s. So as always it is best to google this information when you are about to make a purchase decision. As a cheap made PSU can permanently damage your entire computer if it decides to quit on you. The Linus Tech Tip forums have good information on PSU Tiers, and JohnnyGuru is the industry leader at PSU testing, so checking for more information from those websites will greatly help you make an informed decision if you choose not to buy this PSU.As for this PSU I have no complaints at all, I love the modularity, the A+ build quality, the great packaging, and the price of $109 I paid made this PSU a great deal! Even if you have to pay $20 more this PSU is worth it, and I highly recommend it to anyone interested!
