The Chieftec VEGA M 850W is an ATX v3.1 compliant power supply with enough power to support a strong system, destined either for gaming or for creative purposes. Read the review to learn more about this product!
The Chieftec VEGA M 850W is (or will be) included in my best ATX v3.x & PCIe 5.x PSU picks article.
The CHIEFTEC Vega M series consists of members that adhere to the Intel ATX 12V 3.1 standard, with support for PCIe Gen5 and Gold efficiency. Their capacities range from 750W to 1000W, and in today’s review, I will examine the middle member of the line, which features a maximum power of 850W. All Vega M units utilize a contemporary platform featuring an LLC Half-Bridge design with DC-to-DC technology for generating the minor rails. Most PSUs nowadays costing over 50-60 dollars use a similar design. Additionally, the Vega M units have a fully modular cable design for easier installation. Cooling duties are handled by a 135mm fluid dynamic bearing (FDB).
All looks well on paper, but the testing data will show the capabilities of the Vega M 850W, and hopefully, it won’t disappoint me. The only thing I disapprove of so far in this PSU is that it doesn’t have any Cybenetics ratings, which are significantly stricter and provide a wealth of data, leaving nothing out.
