Antec NeoECO 750W Modular 80 Plus Gold Power Supply Review

Antec is one of the oldest names in the business, having decades of experience in creating cases, coolers, power supplies and much more. Many of my first PC components were from Antec, and I’ve been using their products ever since, given I’m pushing 40 years old now, it’s fair to say I’ve been using Antec for a long time now. Admittedly, it’s been many years since I had the pleasure of testing one of their power supplies, but I know their older units were really well-made and reliable, so I’m hoping to see that still holds true. Admittedly, the NeoECO I’m testing today isn’t particularly high-end, but at just £106 it’s both fairly affordable and offers a good amount of power and efficiency for mid-range system builds.

Antec NeoECO 750W

At 750W it’s far from the most powerful PSU, but if you’re not running a £2000 GPU and flagship CPU, you don’t really need 1000W anyway. However, Nvidia recommends a 650W+ PSU for up to an RTX 4070 and the RTX 4070 Ti should be ok with 750W. AMD recommend 650W+ for the RX 7800 XT and 750W+ for the 7900XT, depending on your CPU configuration too, of course, so you’re not that limited by 750W. However, keep in mind this PSU doesn’t have the 12VHPWR connector, and uses the more traditional 8-pin (6+2) connectors, but otherwise, it is packed with features like 80 Plus Gold efficiency, a DC-DC topology, Zero RPM hybrid fan mode, and more. Antec also offers it with a 7-year warranty, which is great to see.

As a child still in my 30's (but not for long), I spend my day combining my love of music and movies with a life-long passion for gaming, from arcade classics and retro consoles to the latest high-end PC and console games. So it's no wonder I write about tech and test the latest hardware while I enjoy my hobbies!
