Grab this gigantic, 1600W 80+ Platinum power supply for just 33 cents per watt — Seasonic's Prime TX 1600W is down to just $532
An RTX 5090-ready power supply.
While CPUs and GPUs often take front seat as the most important components in a gaming PC, the power supply fueling the system is just as crucial. If you're rocking a high-end build, a good PSU can be the deciding factor between your computer running smoothly or catching fire in the middle of an intense session. That's why it's best not to cheap out and go for something as reliable as Seasonic's Prime TX-1600, which is on sale for just $532.99 on Amazon right now.
A fully-modular 80+ Platinum power supply with 1600W of grunt, coupled with native PCIe 5.0 connectors and full ATX 3.1 compatibility — it doesn't get much better than that. Whether you're building a flagship gaming PC or an AI workhorse, Seasonic's Prime TX-1600 with its 12-year warranty has you covered.
As the name suggests, the Prime TX-1600 is a 1600W power supply manufactured by Seasonic itself. Featuring 100% Japanese capacitors, it's fully modular and has the flagship 80+ Titanium certification from Cybernetics. The unit is also PCIe 5.0 compatible and fully ATX 3.1 ready with dual 12V-2x6 connectors for the latest Nvidia RTX 50 series and AMD RX 9000 series GPUs.
The Prime series in general offers exceptional efficiency, load handling, ripple suppression, and transient response, so the TX-1600 is no exception. It's a relatively quiet PSU enabled by a 135mm fluid dynamic bearing fan with great static pressure, leading to an A rating for noise level from Cybernetics. You also get high-quality PVC embossed cables in the box.
The original unit came out in 2022, and we gave it a glowing review back then for its overall excellent performance. The subsequent Noctua edition still sits in our best PSUs tier list to this day. Seasonic revised the Prime TX-1600W platform to be ATX 3.1 compliant in early 202,5 with this unit in particular featuring native PCIe 5.0 connectors for incendiary GPUs.

TechieTwo IME the Seasonic Prime PSUs are the top of the heap for performance and reliability. They ain't cheap but you generally get what you pay for, especially in PSUs.Reply -
A Stoner I thought this seemed expensive, but apparently mine is a super flower leadex. My understanding is they are near equal peers. I got mine for ~$280.Reply -
spoidz I had been Seasonic on mine and all my relatives builds but there were a few poor reviews for specific models recently - apparently certain models just weren't measuring up in tests.Reply
The >1250 models seem to make the cut but many below that have noted issues.
I now started checking test websites first and ended up on BeQuiet for the 850W for my relatives latest upgrades (Win 11 new hardware)

bmtphoenix Even a system with a 5090 won't use that much wattage, and does not need that kind of wattage. With connectors changing recently, it's not even future-proof in any real way.Reply
Sale or not, this is just throwing money down the drain.
