INTRODUCTION

   With Intel launching their upgraded Z790 chipset, NVIDIA slowly gearing up to update their GeForce line of graphics cards and AMD just having released their new Radeon RX 7700XT and 7800XT graphics cards this is perhaps the best time for consumers to grab one of the latest ATX 3.0 & PCIe 5.0 power supply units. Yes, if you already own a high-end power supply unit (even more so if it's an 80 PLUS Platinum or Titanium certified one) you may not be missing out on a whole lot but again the addition of the new +12VHPWR modular cables combined with improved efficiency levels and up to 3 times the excursion tolerance should be plenty for some people to take that step. Late last year i had the opportunity to review Seasonic's PRIME TX-1300 Titanium power supply unit model (review here) which although not 100% compliant with the ATX 3.0 standard it did come with the latest +12VHPWR power connectors and offered performance second to none. Well, it took Seasonic a few more months to finalize and release the ATX 3.0 variants of their PRIME TX Titanium line and today with me i have the PRIME TX-1300 ATX 3.0 Titanium Power Supply Unit.

   Sea Sonic Electronics Co., Ltd was founded more than 40 years ago by engineers. Since its early beginnings the company has rigorously maintained its focus on the research, development and production of technologically advanced, high quality products. In 1981 Sea Sonic expanded into the production of PC power supplies to become one of the first manufacturers in this market. Soon after, the manufacturing of high quality and performance PC power supplies became the core identity of Sea Sonic.

   Unlike the non ATX 3.0 variant of the PRIME TX series the PRIME TX ATX 3.0 is currently only available in two outputs, 1300W and 1600W and so at least for now it's clear Seasonic made it available for the most demanding users with the top systems available today and for the foreseeable future. Both output models are obviously fully modular, 80 PLUS Titanium Certified (up to 94% efficiency) and as for the TX-1300 which I’ll be testing today comes ready with a single powerful +12V rail (108.33A) capable of delivering the units entire rated output (1300W), micro-tolerance load regulator (under 0.5% load regulation), active PFC, DC to DC topology, cable-free connection design (back panel with PCB), individually sleeved power cables (PVC), peak power output of almost 1450W, fluid-dynamic bearing 135mm fan with hybrid mode (fan starts to operate at over 40% load) and high-quality Japanese manufactured capacitors. Needless to say, the PRIME TX-1300 ATX 3.0 model is fully shielded thanks to its numerous electrical protections such as over-current (OCP), over-voltage (OVP), under-voltage (UVP), short-circuit (SCP), over-temperature (OTP) and over-power (OPP). As for warranty Seasonic once again covers both models of the brand new PRIME TX ATX 3.0 line of power supply units with a very generous 12-year limited one.
