Cougar units may not be as well known as some of the heavyweight industry leaders, even though they’re essentially HEC units which we’ve seen before, but in the lower-to-mid range market, we think the company is doing a fine job putting together respectable units at good prices. Nothing earth shattering here in terms of innovative technology or otherworldly performance, but the Cougar GX-S 600W is a very capable power supply that gets the job done without much fanfare, and it’s a solid unit.

The fingerprint-resistant, textured finish looks good, and the all-black styling is rather stealthy, and should fit well into just about any internal case aesthetic. The durability of the finish, however, is susceptible to scratching so take care when installing the unit.

From a feature standpoint, the unit is 80PLUS Gold certified, which is admirable for a unit in the 600W range at this price point. The GX-S isn’t modular, though that shouldn’t be a surprise for this affordable segment. The varying cable lengths are sufficiently long for mid-tower cases, and for anyone who needs a solid power supply without any frills, particularly in an HTPC setup, have a very good and affordable option with the GX-S.

In terms of performance, the GX-S 600W finished quite well, with some minor movement on the rails during voltage regulation testing, while the +12V was a bit overvolted. Nothing problematic though at all. The ripple results were also strong; not the best we’ve seen, but well within specification and impressive for a more affordable unit unit. The secondary caps are entirely Taiwanese, so Cougar’s validity in claiming Japanese “capacitors” is arguable, though we suspect most consumers likely won’t care about that when balanced against an affordable $119 price tag.

That said, the Cougar GX-S 600W isn’t necessarily a standout in any one respect, but overall it’s a solid package, and a strong value product, providing clean and stable power for consumers who are on a modest budget.
