Cougar GX-S 550 W

The Cougar GX-S550 is an affordable PSU with decent performance, ultra-compact dimensions, and a silent operation under normal ambient temperatures. The only compromise is the lack of modular cables.

What an interesting fan speed curve, there's no curve.

There is, a silent one even, but not with a high intake temperature.

If i'm not mistaken, this seems to be one of the most solid PSUs that Sirfa has produced for quite a long time now.

P.S. Excellent review as always from Aris!

The operating temp of 0 - 40C means it is useless in hot or humid climates.
My bedroom where I use my main computer reaches that in Summer with no air conditioning.

Not true, this PSU only isn't gonna be silent then.

Also 50°C isn't a problem for a PSU rated for 40°C, only some can deliver their rated wattage then, but 80 or 90% of the rated power is normally always possible. Many can even do 50°C fine, even if they're rated for only 40°C.
