Deepcool Quanta DQ750 750W Power Supply

Once in a while, a completely random and unknown product comes in for review. Today, I’m looking at a brand new offering from Deepcool, a company formerly known for cooling solutions, who now wants to make a splash in the power supply business. But do they have what it takes to be competitive in a market dominated by the likes of Seasonic, Antec, Enermax, and Corsair? The Quanta DQ750 is here to answer that very question.

We don’t get a lot of surprises showing up at the door lately around here. By now, most power supply companies are on to us… they know we’re tough on their units, so they don’t send us things that might not pass our load testing sessions. That’s why you haven’t seen a gutless wonder article from me in a while now.

Once in a while, though, we do get something completely unexpected from a company we’ve never heard from before. Such is the case today, as we look at our very first unit from Deepcool, a company founded in 1996 previously only known for cooling solutions. They’re branching out into the power supply market, and we’re going to see just how serious they are about doing it properly.

Today’s review unit is the Quanta 750 watt model, an 80 Plus Gold unit whose box claims the presence of a blue LED fan within.

The box is refreshingly minimal on the marketing hype. We have a few features listed on the back, and not a lot else. 80 Plus Gold. Modular cables. Active PFC allowing for automatic voltage switching. About the only feature, we don’t see on a regular basis is that fan delay on power off, but this is hardly a new feature. All in all, this promises to be a decent little 750W unit with a couple of extra perks thrown in.

Elsewhere on the box, we see this here diagram of the cabling.

Meanwhile, another side of the box shows us a load table.

I’m more interested in what’s inside the box, so let’s go ahead and unpack it.

Looks like we get a power supply, some modular ribbon cables, a Shuko (CEE 7/4) style power cord, a bag of screws, and a warranty card.

As warranty cards go, this one is a little… shall we say… uninspired. First, it’s barely big enough to print any of the requested information on. You’d have to be a gnat to write your name on this thing and not feel cramped. Second, where do you even send this? The only address I see on it is in Beijing!

Let’s look at the user guide now, and… ah, right, there is no user guide. Let’s check the website – maybe there’s one there.

Nope, no manual there. But there is a full-power operating temp spec of forty degrees there, so that will come in handy for later. Hey, wait a minute… the product page says nothing about a fan delay on power off, instead of it’s telling us this unit has a semi-fanless mode. So which one is it? Or do we get both? Both would be cool. Either way, no manual means a scoring deduction. We’ll figure out how to score on the fan modes later. I’d probably go easier on the scoring if the box was wrong instead of the website. After all, you can easily update a website. They have no excuse if the site is wrong. Re-printing a big stack of new boxes? Not so easy or cheap, and I would be happy to let that slide a bit.
