INTRODUCTION

   The latest GeForce RTX 4080 and 4090 graphics cards by NVIDIA may be what many people would like to have in their rigs but let's face it, not everyone can afford (or wants) one. So even though ATX v3.0 and PCIe v5.0 power supply units are the ideal companion for such cards (both due to 12VHPWR PCIe 5.0 connectors and their higher efficiency) they are not a one way, not for people who have no plans about upgrading their systems with one of those cards. As a matter of fact, if you look around you'll find quite a few high performance and quality power supply units which have almost nothing to be jealous from the all the latest additions and the PRIME TX-750 model by Seasonic is clearly one of them.

   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.

   Seasonic first unveiled the PRIME TX line back in 2016 so it's worth pointing out that it has undergone numerous changes since then. Today the PRIME TX line includes 650/750/850/1000/1300/1600W output models all of which are fully modular and feature the 80 PLUS Titanium electrical certification (up to 94% efficiency - the 1300/1600W models also sport 12VHPWR connectors). In terms of available features the PRIME TX-750 features a single strong +12V rail (62A) capable of delivering roughly 99% of the units entire rated output (744W), 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, peak power output of almost 863W, fluid-dynamic bearing 135mm fan with hybrid mode (fan starts to spin at over 40% load) and high-quality Japanese manufactured capacitors. Just like its larger brother (PRIME TX-1300 / review here) the PRIME TX-750 is also fully shielded by an array of electrical protections including over-current (OCP), over-voltage (OVP), under-voltage (UVP), short-circuit (SCP), over-temperature (OTP) and over-power (OPP). As for warranty once again Seasonic covers the entire PRIME TX line of power supply units with a very generous 12-year limited one.
