I want with another brand and after about two weeks that power supply went out so I decided to go with this brand since it been around for awhile and is a manufacturer of power supplies for other companies also. It still going strong over two or three months without any issues.I bought two of these, 1 for my son and the other for my computer and they both worked well. I would recommend buying these if your machines need 1200W or less power. This also comes with the 600W power supply cable and is the new standard for the Nvidia 40 cards.The only thing I would do differently is buy the gold version of this as there is that big of a difference between gold and platinum efficiency ratings. ### ⭐⭐⭐⭐⭐ Runs a 5090 without spending a fortune. Seasonic quality. *by on Reviewed in the United States May 25, 2025* As expected from Seasonic it works perfectly and has plenty of cables. The were nice enough to send me the updated power cable for my 5090 for the cost of shipping despite being past the 90 day cutoff from day of purchase. It hasn't melted yet after a couple months of gaming. Power supply is quiet and I don't notice it. As it should be. ### ⭐ HEADS UP — READ THIS BEFORE YOU BUY A POWER SUPPLY FROM SEASONIC *by on Reviewed in the United States August 28, 2026* If you are considering buying a Seasonic power supply because of their advertised 10- or 12-year warranty, I strongly recommend you read my experience first.On August 1, my workstation suddenly experienced a power disruption, and the Seasonic power supply completely failed. The unit was only nine months old.Fortunately, I immediately took my workstation to a professional computer repair shop. They diagnosed the problem and confirmed that the power supply was completely dead.Because I rely on this workstation, I decided in good faith not to wait weeks for Seasonic. I purchased another brand-new power supply at my own expense so I could get my system back up and running. I then contacted Seasonic to deal with the defective unit under their warranty.That is when the nightmare began.Today is August 27 — almost one month later — and this warranty process is still an unbelievable experience.First, I was instructed to complete an RMA. The RMA process itself was a disaster. I spent nearly two hours trying to complete the online form, but the website repeatedly failed. I reported the problem to Seasonic, and eventually they had to handle the process another way.I also had to argue with them over the return shipping. I told them that I should not have to pay to return a power supply that failed after only nine months. Eventually, Seasonic provided a return label, and I shipped the defective unit back.Throughout this process, I repeatedly made one thing absolutely clear:I purchased a brand-new power supply, and because it failed within the first year, I expected a brand-new replacement — not a refurbished, used, or downgraded unit.After waiting, I was told the replacement was being shipped.Then came another problem.The shipment required a signature.I missed the first delivery by only a few minutes and had to spend an entire day waiting around for the package. The following day, I again had to wait until the end of the day before the package finally arrived.That's two days of my valuable time wasted simply trying to receive a warranty replacement.But the biggest shock came when I finally opened the package.Look at the condition of the package and the replacement unit in the photographs I am posting.After repeatedly telling Seasonic that I expected a brand-new replacement, this is what I received.I don't know whether this unit is refurbished, previously used, or a customer return. I cannot make that determination. But based on the condition in which it arrived, I certainly would not consider it a brand-new replacement. Also will not risk another $250 computer shop fee.And there is another issue that makes this even worse.The power supply that failed was a VERTEX GX Series ATX 3.1 unit.The replacement Seasonic sent me is an ATX 3.0 version.So I paid for the newer-generation product, the newer-generation product failed after only nine months, and instead of replacing it with an equivalent brand-new unit, Seasonic sent me an older-generation version.How is that an acceptable warranty replacement?I have been in the post-production business for approximately 40 years, and I have dealt with countless manufacturers and technology companies during that time.When an expensive piece of equipment fails within its first year, that should be an alarm bell for the manufacturer. A company that stands behind its product should be doing everything possible to take care of the customer — especially when the product is advertised with a 10- or 12-year warranty.Instead, my experience has been the complete opposite.The RMA process was frustrating.The website failed.I had to fight over return shipping.I had to purchase another power supply out of my own pocket plus $250 installation just to keep my workstation operational.I lost two days waiting for a signature-required delivery.And after all of that, I received a replacement that appears to be in questionable condition and is an older ATX version than the product I originally purchased.And I'm not the only person reporting problems. There are numerous negative customer reviews describing power-supply failures within 6 months and warranty frustrations.So this is my warning to anyone considering Seasonic because of the advertised 10- or 12-year warranty:Don't just look at the number of years printed in the warranty.Look at what happens when you actually need that warranty.I bought Seasonic because I believed I was buying a reliable, high-performance product from a company that stood behind its warranty.After this experience, I deeply regret that decision.I'm sharing this because I don't want another customer to spend hundreds of dollars on a product believing that a 10- or 12-year warranty automatically means they will receive the kind of support they reasonably expect when the product fails.Please look at the photographs and make your own judgment.This has been one of the worst warranty experiences I have encountered in my 40 years in the post-production business.And honestly, I wouldn't wish this experience on my worst enemy.Think twice before buying. ## Frequently Bought Together - Seasonic Vertex PX-1200-1200W - 80+ Platinum - ATX 3.0 & PCIe 5.0 Ready - Full-Modular - ATX Form Factor - Low Noise - 12 Year Warranty - Nvidia RTX 30/40 Super & AMD GPU Compatible - Samsung 990 PRO SSD 4TB PCIe 4.0 M.2 2280 Internal Solid State Hard Drive, Seq.
