Way back in June, we looked at Corsair's newest take on the TX line of units for the first time, and found that it was exceptionally well performing for something that wasn't being pointed at the high end market. I'm really quite excited, as a result, to see what the 750 watt model in the line can do.
Of course, this unit is being marketed in the same way. We have all the same bullet points on the box about 80 Plus Gold certification, all Japanese capacitors, thermal fan control, and superior voltage regulation/reliability. But what you may remember about that 850W model was that the word "superior" was practically an understatement. That beast had near mythic level regulation, something unheard of even at the high end a few short years ago.
Since this unit is smaller, it may well prove itself better than even its big brother. But before we get to that part of the review, we do need to get the box pictures and a few other things out of the way first.
We've already seen this stuff before, so I'll just gloss over it today. Much of this part of the box focuses on efficiency, fan noise, and how easy the unit is to install thanks to those modular cables. I will personally add that the unit is only semi-modular, with the ATX and CPU cables fixed. But that's okay, almost all of us will need those cables anyway.
Compatibility is also touched on here, but because we know this platform has DC-DC conversion topology we can be pretty sure no processor will throw it for a loop when it comes to crossloading. These designs can take zero load conditions better than even the indy regulated units of days past could.
Reliable? Well, we should certainly hope so. I don't buy stuff I don't think will hold up, and am usually pretty quick to tell you guys about it if that's the case. Fortunately, Corsair has never really had a big problem there with any unit I can think of. Sure, a lot of people whine about the older CX units, but a lot of those people don't get something fundamental about that line... it was really freaking popular. Everyone and his dog bought one.
If you sell a million units and they have a 1% failure rate (not saying the CX units were that high... or low... or sold that many), that still works out to ten thousand units that get RMAd. The majority of those will be from people who plugged the ATX cable into their noses or some other nonsense and complained it wouldn't turn on, while some will be legit failures. Even fewer numbers will be legit failures that took out other hardware, because you and I both know I personally looked at those units and found nothing to support any idea that the protection in them was lacking in any way. In fact, the newer CX units are exactly the same, just with increased ability to handle heat before shutting down.
But because you still had those ten thousand unhappy customers out there, and it's more fun to complain than say, "Day 325... unit #264,748 still works, everyone!", that's all you ever heard. "The CX units are crap." "The CX750 killed my dog." "The CX550 said something bad about my mother and then ate all my cake." "The CX650 is only rated to thirty degrees, so that means it will explode at thirty-one. I better go tell people it burned my house down... it didn't but it could because I'm a Doctor of the Internet with a degree written in boogers that says I know everything, so it's ok if I exaggerate just this once."
What am I saying? Do your homework before bashing units or ruling them out on hearsay. You don't have to come to this site and take my word for it, there are lots of other good ones out there. Reviews written in crayon on a retailer website don't count.
Rant over, let's look at some pictures of cables. This being a power supply, we can expect a few of them. No, you do not plug any of these into your nose. I tried, they don't do much besides get the tomato juice to come out.
Elsewhere on the box, we get a few more compatibility points to read. Auto switching, because it's a unit with active PFC being sold in North America and Japan as well as other places worldwide that run at 240V. Supports ATX and EPS standards, because it literally has to before it works with anything being sold as computer hardware. Has dimensions because it's a thing that exists within our universe.
I do like that this one is a touch shallower than the 850W model... it's not much shallower, but sometimes that makes all the difference to some people.
Unpacking the box, we find the same stuff we found in the bigger unit's box. A manual, a warranty guide, a safety guide that for some reason lacks the lyrics to Safety Dance (shame on you, Corsair!), a bag with some zip ties and screws, some modular cables, a power cord, and the power supply itself.
I have no issues with the documentation. Though it is lacking in person, additional information is available at the site to make up for that. No need to kill a thousand trees just to tell us the unit can handle fifty degree thermal conditions at full power.
