Get Your Money's Worth
||Posted . Owned for 2 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I mean, it's a Seasonic platinum PSU - what do you expect? Fairly expensive, but it runs basically silently, it's efficient, and the full modularity is nice for keeping your cables tidy. I do wish it included some 1-1 cables instead of just daisy chained molex/sata/pcie ones, but that's just a personal preference for neatness. All things considered, a PSU isn't something I'd go cheap on, and this one and the GX-850 are both extremely solid choices.
I would recommend this to a friend - Pros mentioned:10 year warranty, Reliable

One of the BEST power supplies out there!
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Seasonic is one of the best power supply companies out there. The parts inside this PX-850 are all high quality with all Japanese capacitors. The unit is absolutely SILENT at idle and fans don't even kick in until it hits 30% load. And even when it comes on, you can barely hear it. There is a switch in the back that allows you to switch between the fan always running and only when it hits the threshold. For the sake of longevity, I kept mine always on. I can't tell the difference in noise level from about 3 feet away. For reference, my PC is next to me on my table. As this is a Platinum 80+ rated unit, it is over 90% efficient when you are running in it's sweet range of about 50-60% power draw. I immediately noted that my PC idle going from 180 watts down to about 153 watts after switching out the Apevia Gold 80+ 800 watt PS that came with my CyberPowerPC that I also bought here from BestBuy. (The OEM PS ran at full tilt regardless of the load and the noise drove me nuts!) And with only quality parts inside the Seasonic, you get a full 10 year warranty. That just tells you how much confidence they have in this particular design. If you are able to get your hands on this, I suggest you buy it right away. Power supplies have gone up in price and gone down in supply dramatically during the pandemic. That and you are also competing with people who build PCs to mine cryptocurrency. I was honestly surprised that BB actually carried this hard to find model. I believe I bought the last one in my region as it was no longer available for purchase either online or in store after I checked out.

Bulletproof - Titanium power supply from Seasonic!
Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Replaced a thermaltake 850w psu that also worked well - but was only gold certified. Best Buy had this in stock and I was looking for a titanium - 850w psu. This was about 1 inch shorter - compared to the Corsair and Thermaltake psu and higher wattage.

Good for RTX 3000 series
||Posted . Owned for 1 week when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Works great so far. I have a RTX 3090 and 3060 Ti on hand, and this has everything you need to run one. I've only tested hooking it up to a 1660 Ti so far, but I know that it would work fine with a 3090. You need anywhere from 750 to 1000 watts minimum for a full system with a 3090, and this card has more than enough juice for most systems. (The 3090 FE has a 350 watt TDP, but some of the custom cards are over 400 watts at this point ... just depends on whatever else you have in your system.) It has a PSU tester in the box that's very convenient if you want to run/test the PSU without having a motherboard plugged in. This little adapter just shorts the green wire with a black ground wire which you can do with a paperclip, but it's a nice little bonus that they're including an adapter these days. I'm using it on my test bench without a motherboard at the moment. It appears to be very quiet so far, and I haven't noticed any coil whine. My environment is kinda noisy, so YMMV. The reviews/benchmarks out there look good. I don't have any complaints. If it's in stock, grab it!

Excellent premium power supply
||Posted . Owned for 1 week when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.A great power supply from one of the top name in PC power. Thoughtful modular design, very good power efficiency, pretty good documentation. This power supply has switch that enables a hybrid fan mode where the fan only runs when necessary. This is a great feature for people who want a quiet build. Some of the modular power cables are a little stiff and hard to work with but they can be replaced with high quality aftermarket parts. Comes with a 10 year warranty, which speaks to the quality of this part.

Great power supply
||Posted . Owned for 1 week when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.This power supply has worked very well. Mine did not include the cloth bag as pictured due to covid mask manufacturing, not a big deal but thought I'd mention that. Its a bit smaller than a regular psu so it'll fit better in some smaller cases, but keep in mind that it's not small form factor.
