If you enter the model number here https://support.lenovo.com/us/en/partslookup you can get all the component specs. It says this model is 100-240Vac,400W 90%, I believe 90% qualifies as gold, the Intel versions of this product line are advertised on their site as gold and show up in the component list as 90% also. I have been unable to find info on the AMD models on their sales website, but specs are available through model numbers in the link I shared. I haven't purchased yet, but this product line has great components for the money, you cannot build a complete system with comparable components for the Legion prices, This model is a contender for me, but the power supply on this is scary weak especially when upgrading RAM is likely immediate and a new Video Card within a few years seems inevitable. There are other good options in this product line, but this has the best processor by far (the Ryzen7 version) and is a very good price. All the Legion desktops have NVME SSDs so they're very fast from from the factory, 32 GB transfer opposed to 6GB with traditional SSD's. (It's crazy they don't advertise these things) I wish they offered this processor with a RTX2060 and larger SSD though, they have one like that a bit more expensive with a low end I-5, which is also a contender for me. If I were to get this though I'd immediately upgrade to a 512 or terrabyte NVME SSD, and remove the other hard drive, I don't need a drive that big cooking the box and slowing the system. Samsung 980 Pro or WD black SN 850 NVME SSD are available here at great prices and currently have the 5th and 1st fastest benchmarks, well worth 130-230$ for me, and are 7x faster than my current SATA 850 EVO SSD. I'd likely wait to upgrade power when I upgrade GPU or add RAM. I've read also from a review where someone added a drive to an Intel version, he said the wire system is hard to access, that should be a consideration also for future upgrades in power management. I'm currently debating between this and the I-5 with the RTX2060 It's 50$ more, but has 650 Watt Gold power and has only a single 512GB NVME SSD which should be plenty for programs and files for several years, and might not justify the purchase of the fastest bigger SSD. It's likely the video card will be relevant longer and a CPU upgrade might be cheaper than a PSU, and GPU upgrade in a few years, or unecessary. Comparing benchmarks though, the Ryzen7 is almost double the speed of the cheap I-5, and the video card is only about 1/14th faster in the other, but has the current tech. It's a tough call, but the power issue is a big one. Another thing influencing my purchase is the next gen chips are likely going to be ARM based and destroy anything anyone can buy right now, but it might be a year or two before they're available and work out the kinks, I'm running windows 7 on a 3rd gen I-7 with a GTX-970 and am hitting the limit on my SSD. To make this thing run modern programs I'd need a new SSD, OS, and the video card will barely scrape by... If I'm going to monkey around reinstalling everything and invest 200-500$ just to scrape by I might as well get something new. It's a tough call. The Lenovo website has been a good resource and their sales number has been very helpful with questions and resources.
