Cougar GX-F 750W Power Supply

It’s time to have a look at another Cougar unit. This is a company we don’t hear from too much, but they are keen to keep us aware that they do in fact offer power supply alternatives to the bigger names out there. Today, we’ll be looking at the new GX-F series at 750 watts. We’ll find out if it’s worthy of our hard earned dollars.

Cougar GX-F 750W

“Real gear for real gaming,” promises the box we have before us today. It’s been a little bit since we last looked at a Cougar unit, but today we’re breaking that spell with the 750 watt GX-F unit. Cougar hasn’t been all that prominent in an industry dominated by the likes of Corsair, Seasonic, and EVGA, but they’ve been around for a while now and would clearly like to get some more of our business.

Normally there’s a lot of marketing already on the front of a retail box, but this one is pretty sparse. All we know so far is the power output, the warranty length, and the 80 Plus certification. I’ll just swivel this thing around for you and we’ll see what’s on the back.

I like that this unit is apparently spec’ed to run at fifty degrees, full power. I don’t normally expect that kind of thing from any less than the high end units in the consumer pool, but it’s definitely a good thing if you want to make a splash these days. The box makes much of the HDB fan as well, though I really have no idea how long Cougar fans tend to last. Except for the one I bought for my last build’s CPU cooler that is up and running perfectly to this day. Either way, with a seven year warranty, I don’t plan on worrying about this one.

I’m not in love with the capacitor graphic on this box, which promises that 105 degree Japanese capacitors extend lifespan by 300% compared to 85 degree parts. First, I haven’t seen a power supply in a long time use 85 degree parts on even the primary side, where the temp rating is less critical. Second, I have never seen 85 degree parts on the secondary side of any good unit. Ever. And this is by no means an indication a capacitor is going to last 300% longer than anything. It depends on many more factors than just temperature and where the capacitor is made. It gets even more interesting when you look closely at the box and realize that Cougar is bragging about only the main filter cap and standby caps. No mention is made of any others, which I’m betting means that we’ll find non Japanese parts all over this unit on page five.

Not that it’s a bad thing to go with Chinese capacitors, mind you, I just think it’s interesting Cougar’s drawing attention to the Japanese stuff when there might not actually be much from Japanese names inside this unit.

The “refined” section is a mite interesting, too, drawing attention to the soldering quality and transformer of the unit. I’ve got no way of evaluating the transformer by itself, but will certainly be looking at the soldering later on.

Elsewhere on the box, we have a simple load table and chart with the connectors supported by the units in this product range. All good things to know. I’ve got the biggest unit in the range, it seems.

It is time to undress our Cougar, said yours truly never because people keep sending me the wrong kind of cougar. I’ll just get this box unpacked for you now.

We have some accessories in a bag, power cord in a bag, power supply in a bag, modular cables in a cable tie, a manual, and a card intended to sell more Cougars.

The manual looks pretty low effort, but is actually quite decent so I won’t pull points later.

The power cord is obviously not intended for this side of the pond, so I’ll be using one from one of the many other units I’ve tested over the years.

Not too forthcoming with the accessories, all this unit comes with there are some screws and a few more cable ties. That’s okay for this market segment… 80 Plus Gold is no longer considered the state of the art for these things. That would be Platinum and Titanium, now that it’s become much easier and cheaper to produce good units at those levels of efficiency.
