Seasonic's Core GX line includes three members with capacities ranging from 500 to 650 W. All are fully modular, have compact dimensions at only 140 mm long, and are covered by a seven-year warranty. There are also the Core GM (semi-modular) and Core GC (fixed cables) lines, which are more affordable. The Core GX-500, which I will evaluate in this review, features 80 PLUS Gold efficiency. On the Cybenetics scale, it is Gold rated with 115 V input and only Bronze with 230 V because of the low power factor (PF) readings. It is also rated as Cybenetics-A in noise output, so noise output is very low. It is always nice to look at affordable products by known brands like Seasonic since most users can't or don't want to spend the $100 or more on a high-end PSU. That said, with a price close to $80, the GX-500 isn't actually that affordable, which does mainly have to do with the increased demand and low availability. This PSU would normally go for around $50-60, which is a fair price given its features. At $80 or more, it is just too expensive, especially considering the sleeve bearing fan. Its warranty is long, though, and should you need it, Seasonic customer support is good.
