EVGA SuperNOVA 550 G3, 80 Plus Gold 550W, Fully Modular, Eco Mode with New HDB Fan, 7 Year Warranty, Includes Power ON Self Tester, Compact 150mm Size, Power Supply 220-G3-0550-Y1

So I have had this Power Supply two years now. I bought mine from Amazon Warehouse. It was listed as Used - Like New. And boy was it. It was brand new in the box and hasn’t been opened. The box just had a minor scratch/ding if you would even call it that. Product came just as if I got it new and I only paid 74.99!!! I have the EVGA G3 Supernova 850 Watt 80+ Gold version. Wow this thing is amazing. Fully modular, braided cables, 80+ gold, very very nice box, comes with a case for the PSU itself as well as a case for the extra cables. If you look up google reviews on this PSU you will see how amazing it is. 10 year warranty says it all. In testing they found out that EVGA could have listed this as a 1000 watt platinum rated power supply. It took over 1050 watts to shut this thing off! By far the best PSU I have ever owned. I’ve had it for two years and not had a single issue ever. I’ve never heard it once till this day. It runs so cool and quiet I had to check and make sure the fan was working. I’m not easy on it either. I have an Asus Prime X570 - PRO motherboard with an 8pin plus 4 pin cpu power. My system has a Ryzen 3900X overclocked, RTX 2070 Super massively overclocked, 32GB of G.Skill 3600mhz Ram, 6 case fans, a PCIe wifi 6/BT 5.0 wireless adapter card, one HDD, 3 sata SSDs, and two NVMe M.2 SSDs. My CPU cooler is a huge Noctua NH-D15 with twin 140mm fans as well. I provided some pics but that was before I upgraded the case, GPU, and CPU cooler. In this pics the GPU is a GTX 1070 and Hyper 212 Evo cooler with twin 120 fans. My PC also has a optical drive, NZXT LED touchscreen that controls my temps and fans, a portable SSD, headset, keyboard, mouse, sound system, microphone, RGB gaming desk, Xbox One controller, duel monitors, and other things plugged in still. I have tons of things being powered by this Power Supply and my PC is on and running anywhere from 5 to 10 hours a day, everyday. I can’t praise this PSU enough. Once again I got this 850 watt, 80+ Gold, fully modular, 10 year warranty EVGA G3 Supernova for 74.99! I can’t stress how amazing of a deal that is for the PSU I now have. I would def pay full price for this. A PSU of this quality that will last you 10 years at the very minimum. You can’t beat that imo. Plus its completely silent, runs cool, looks super nice, and the cables are very high quality. 850 watts is enough to power whatever 99% of most people would ever need. I have between 3-4000 dollars in my PC now and it’s a beast. I don’t even come close to using 850 watts. If you catch this PSU in stock and most definitely if you catch it on sale buy it instantly! 11/10 from me. Before this I had a Corsair 750 watt PSU and this unit blows it out of the water in every way possible. EVGA fan for sure now. So much that my RTX 2070 Super is EVGA and it looks and runs just as nice as this Power Supply and comes with the same fantastic warranty(even tho I voided it on the card lol). Just buy it.

Writing this review in 2019, I have an older Haswell i7 build with a GTX 1660Ti and it's still a very strong system for gaming... after getting the 1660Ti, I wanted to "add some bling" to my system, so I decided to get a new case and some custom cables for the PSU. I had an older EVGA 750 Bronze semi-modular PSU, and while I had no problems with my older PSU, it was both a Bronze and I wanted full-modular for the cables I had in mind (I didn't have room for custom extensions, I needed to use custom replacements). First off, there are MANY sites that offer wattage calculators for how much your system draws at peak useage... long story short, the average home computer with a single graphics card usually maxes out around 300W give or take. That doesn't mean buy a 300W PSU (don't do that!)... you never want your system to reach your PSU's max wattage, and the most efficient power draw a PSU ever reaches is usually around 50% max load... so if your system pulls around 300w, you want a PSU around 600w capacity for maximum efficiency. So unless you're running a ton of peripherals and two or more graphics cards, the average computer owner should be looking in the 550w-650w range... anything more is just throwing your money out the window and your PSU will be less effiicent since it won't even reach 50% of it's max draw. I was very happy with this PSU... it's the perfect wattage, it runs very quiet, it has an econo-mode, it's small, its fully modular, and the cables that come with the PSU are all black wires from beginning to end... not a single "ketchup and mustard" wire to be found with this PSU. It even comes with a bag to hold all your modular wires that are not in use. Also, becuase it is fully modular, it makes it easy to get replacement cables for custom wiring jobs as-in my pictures. I purchased the Cablemods E-Series replacement cables for my G3 PSU and was very happy with the results. Make sure after you purchase your EVGA PSU you register it with EVGA (through their website) to get the extended warranty... you have to register within 30 days of purchase to get the extended warranty... otherwise, you're stuck with a much shorter warranty. It's free and only takes a couple minutes, so make sure you knock that out! I've been using multiple EVGA PSUs for the many systems I have in my house and have never had one fail on me... I might replace one from time to time for various reasons, but it's never been becasue of a failure. EVGA has me as a happy return customer! You'd be wise to get one of their PSUs.

It powers my computer. Remarkable 5 stars

No issues here, everything works well.

I’ve had this PSU running my i9 / 1080ti for a while now. Replaced my HX1000i that blew up on me.

robust, easy to connect

Very quiet and great for powering my pc with no problems.
