EVGA SuperNOVA 550 G3, 80 Plus Gold 550W Fully Modular Power Supply with Eco Mode and New HDB Fan

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.

In a word, Superb. Easy to install, 4 simple screws attaches it in standard mid or tower desktop case. Plenty of nice features & like many PSUs of this caliber, multiple 12V rails to bear the load. Though you come to expect that from 80Plus rated PSUs. They don't call this a SuperNOVA G3 class PSU for nothing. This PSU surprisingly powers my 165W Core i9 10920X based HEDT Computer with no problems, and apparently has some head room to spare. Basing this on load to my UPS battery backup & CPU-Z Hardware monitor. I wasn't sure it would handle it at first. In fact, I almost wished I'd gotten an 850W or more to be sure I'd be OK power wise, esp for an HEDT PC. But after seeing it in action last couple months, I have no complaints. Another plus is the fully modular cable support to keep excess cables out of your case. Also I love the 10 year warranty by EVGA (w valid receipt, 3 years without). But the best part is it is so QUIET. I cannot hear it at all! Something I discovered these G3 class PSUs have is an Eco mode switch on the back, which only powers the PSU fan if it's needed. At first, I thought why is the fan not running? Then I saw the Eco switch. Aha, of course! Eco mode was ON. Duh, No wonder it's so quiet! Lol! But even when the fan is running you still can't hear this high class well made PSU. Well done EVGA for such a superb quality product & Thank you Amazon!

My Corsair CX500 has served me well for years. But when I began upgrading my unRaid server to a 16 drive server case, I knew that the power supply needed upgrading as well. When I began looking for a replacement the following were important:- Modular- 650 watts or greater- 80 Plus Bronze or greater- Plenty of SATA power connectionsI had never used an EVGA power supply but the EVGA SuperNOVA 750 G3 fit the bill. I could have gotten away with the 650 but I needed the extra 3 SATA power cables that the 750 came with. At the time of purchase, it was moderately priced at $111 but it came on sale a few days later at $79.99. Amazon was quick to adjust my price after a quick call to customer service.Installation was a breeze. I've built plenty of systems but this was my first time using a fully modular power supply. I have to say, I'll never again use any other type of power supply: modular is THE way to go. Since this was going into a file server, the supply came with a lot of cables I didn't end up using. I didn't have to sit and zip tie wires and try to organize them like I did with the Corsair either. Performance wise, this thing just works. I mean, there isn't much to say about a power supply other than it works and it does so efficiently. I can't comment on the sound because my server case has fans blowing at full speed to keep the drives cool. We'll see how long this one lasts but it looks well-built. For a 750 watt power supply it's also pretty compact.The 10 year warranty is also a great selling point just be sure to REGISTER WITHIN 30 DAYS OF PURCHASING!
