EVGA SuperNOVA 850 P2, 80+ Platinum 850W Fully Modular Power Supply with EVGA ECO Mode

I purchased the EVGA fully-modular 1000watt platinum power supply for $185. I previously had a semi-modular SeaSonic PSU that worked very well and still does to this day. I upgraded because I wanted to add another 780ti to my system and needed the extra juice as well as cleaner wiring offered from a fully-modular supply to allow for better cooling on the bottom GPU. I picked EVGA because it is one of the most reputable computer part makers in the business. (I buy nothing but EVGA graphics cards, as they offer wonderful warranties and are renowned for their outstanding and prompt customer service.) This power supply is no different and comes with a 10 year warranty. Knowing EVGA, I have no doubt that they will take care of the issue in the unlikely scenario that I actually have an issue.While the PSU is on the expensive side, this is because of the 1000 watt capability which is on par with other manufacturers such as Antic, Rosewill, and SeaSonic (which as actually considerably more expensive at the 1000 watt power bracket.)The PSU comes nicely packaged with a carrying case and many connectors (some red, some black.) I ran the red power connectors to my GPUs and it looks very nice. The wires look to be of very good, solid quality. The wires also have adequate length, allowing me to route them properly and get the CPU connector tucked away nicely, which I did not have enough length to do on my previous seasonic PSU. The 1000 watts of power are more than adequate to run dual sli 780tis at stock voltage (which you probably only need about an 800-850 watt PSU to do,) but it gives you plenty of headroom to turn up the voltage if need-be. The PSU runs very quietly and I cannot hear it over my case fans (even on the low setting, which is actually very quiet.) The PSU also has an eco-mode, which can be turned on by flipping a switch on the back of the power supply close to the power button. I have not turned this feature on at all, but I believe it turns on the fans less often or maybe only when needed rather than keeping them on all the time. With the platinum efficiency of this power supply, the damage on the electricity bill is already minimized, and this eco-mode is an available feature for those that might want to use it. Overall this is a very good power supply, well worth its asking price and more than capable of its claims. I highly recommend it to anyone wanting to run multiple GPU setups and I cannot imagine that the less powerful PSUs in EVGA's lineup are any less worthy.

This review is for the 650 Platinum power supply.After the original bronze level EVGA power supply went out after about 4.5 years of continuous 24/7 use in a security camera server, I decide to get something a little more heavy-duty component wise and purchased this platinum level power supply. This power supply is definitely a step up from the previous bronze power supply, which provided 500 watts of continuous power. This one is not only capable of 650 watts but has a much better warranty at 10 years versus 3 for the bronze one.This is a really good quality power supply that feels very solid. Best of all this is a modular power supply making it easier to customize as my previous power supply was not. Included are tons of different cables for most applications as well as a power supply tester. To confirm my paper clip test on my previous power supply, the tester confirmed my previous PS had gone out. The power supply was easy to put into the case and connected easily. It didn’t like some of my cables from another PS that I was using as a temporary unit until I got this one installed and I had to switch to the new ones that came with the PS, but otherwise I had no major issue with the installation. When the PS is powered up the fan is silent and works efficiently. The eco mode (enabled by a switch on the PS) seems to work fine on my camera server and I like the fact that it saves some wear and tear on the PS.So far, no problems with the PS. I think it is a bit expensive, but as long as it lasts through its 10-year warranty, I will be satisfied with it. I will update my review with any long-term durability issues as this will be running continuously for the camera computer server.5 stars

Let me first start off by saying I’ve been building computers for 2 decades. I have experience with this stuff.One major rule of building? Don’t get a cheap heart. PSU = Heart of your build.Things I consider when buying PSUs? Quality, Longevity, Rating, Noise.You cannot go wrong with EVGA components ever. These is a brand that does NOT cheap out, but in return you pay a premium. Is the premium worth it for all their products? Debatable. Is it worth it for PSUs? 100%.This thing is small (140), packs a punch at 850w, and is rated for 80+ platinum. It’s also fully modular, and is future proofed. It can run modern day cards without needing to daisy chain your PCIE 6+2 cables (comes with 4 cables and has 4 individual PCIE/VGA power slots. Currently running an MSI RTX 4080 Trio X and an i7-12700k and have zero issues.The cables that come with it are high quality and have a decent amount of play, not too stiff, meaning you can run them through your case easily. They are also decently long and gave me zero issues with my Hyte Y60 case.Last plus? No noise. This thing has no noise or that sometimes annoying PSU slight chemical smell.The ONLY thing I will tell you to do, is flip the eco mode button on the back to “Off”. Eco mode isn’t reliable with power management on ANY PSU.Enjoy it. Don’t buy garbage, buy this.
