DeepCool DQ850-M-V2L Review – High-quality PC power supply in test

In this review, I introduce the Deepcool DQ850-M-V2L 850W power supply, test the product’s scope of delivery and quality, and rate it.

The company Deepcool has so far been represented on the market mainly with fans and water cooling systems. With the new series of power supplies, they would like to expand their product range into other areas of PC DIY hardware. In this DQ850-M-V2L review, I introduce, test, and evaluate the 850W model in the series. There are comparable versions in 650W and 750W as well as a DN series and a DA series, but I don’t have those available.

Preface and Notice:

I received the product for free as part of Alternate.de’s “Test, Evaluate, Keep” promotion. However, this review is independent of this campaign and is in no way connected to the company Alternate per se. My evaluation is as neutral as possible, and I will of course also point out problems and flaws if they exist. I always write all my reviews with the thought in mind, how would I feel if I had paid the full price.

General – PC Power Supplies – Quality and Reliability

In low-priced all-in-one devices and pre-built systems or if the PC manufacturer saves money at the wrong end, you can quickly get an extremely cheap power supply unit installed that is supposed to deliver a certain power according to the datasheet, but in the end only does so under the most favorable conditions. This can lead to all kinds of problems in later operation, if the hardware that is operated with the power supply is then not reliably supplied with stable voltages, hard to understand crashes or possibly even hardware defects can be the result.

And also with the effectiveness of the conversion of the voltages in the power supply, one would like to consider perhaps rather 2 times whether one buys the cheapest power supply or a quality grade better because by a bad efficiency one gets fast an unnecessarily higher power consumption. And so the 20 euros or dollars that you saved on the power supply could quickly be wasted on the electricity bill. And then usually even add some more euros/dollars in addition, since you often operate such a power supply for many years and several hours a day, and at power levels of 500-800W, 10% difference in efficiency is very noticeable on the electricity bill.

Therefore, I can only recommend, especially when choosing and buying a power supply, to pay attention to high-quality parts and components and to a gold or platinum certification as well as long warranty periods. Because if a manufacturer gives only 2 years warranty on a power supply, this device is probably not so durable and thus this can quickly become a danger for the entire hardware, and in the worst case also a fire hazard in the home.

So you should definitely look a little closer, not only on the price but also pay attention to the technical data and the warranty periods, and then, unfortunately, a wide range of suppliers of cheap power supplies quickly drop out of the race. A few specific companies remain, such as Seasonic, BeQuiet, Corsair, and a few more. The Deepcool company is now also trying to get into this slightly higher-end power supply market with the Deepcool DQ series presented here.

And this is what you want to have when you entrust the life of your expensive PC hardware to such a device in the end. Because voltage spikes or drops under high load at the power supply can quickly cause crashes and spontaneous shutdowns in later operation. And there I can only recommend to rather spend a few extra tenners for a good power supply, instead of possibly risking broken devices worth a multiple of a good power supply due to a cheap PSU. An expensive graphics card from Nvidia or Radeon or a power-hungry CPU from Intel or AMD Ryzen should rather be supplied with “quality fodder”.

Deepcool DQ850-M-V2L – About the power supply itself:

The DQ850-M-V2L has a rated power output of 850W and with an 80 Plus Gold certification, this is probably also a very reliable specification. According to the manufacturer, the power supply has an efficiency of up to 91.3%. This is always dependent on the attached load, but such a high efficiency ensures on the one hand that the electricity bill does not rise unnecessarily in the height and on the other hand is not generated unwanted heat, which must then be cooled again, which could be heard as a result possibly by loud fans.

The fan of the DQ850 is relatively quiet compared to previous and comparable power supplies of mine. The case looks and feels very sturdy and quality and is completely black, except for some lettering in green and white. The device doesn’t have any RGB flashing, but I see that as more of an advantage for me.

Not only are the electronics 80 Plus Gold certified, but they are made with high quality Japanese components. So from the electronics side, they went for quality here and not cheap components.

As particularly worth mentioning and positive I feel the 10-year manufacturer warranty. This shows that the manufacturer has confidence in its own devices. Here you don’t have to be afraid of early failures. The manufacturer specifies the MTBF (Mean Time Between Failure) with 100,000 hours, but I didn’t have the time to check this ;)

DQ850-M-V2L – Technical data

The following are the technical data and specifications according to Deepcool’s manufacturer website

Related products:

In the same series as the Deepcool DQ850-M-V2L, the manufacturer also offers models with 650W and 750W. These are then called Deepcool DQ750-M-V2L and DQ650-M-V2L accordingly. Except for the lower output power and the correspondingly lower price, all three models are identical and therefore this rating should also be largely transferable to the other two models.

Deepcool DQ850-M-V2L – Connectors:

The modular design saves unnecessary cables in the case, I really like that. So cable management during installation is quite easy to handle.

In addition to 2x motherboard and 1x CPU connector, there are 4x 8pin and 4x 6 pin Molex connectors on the unit. Besides the cable for the motherboard, 2x 8Pin cables were included, labeled CPU. In addition there are 3x 6Pin to 2x SATA/2x4Pin Molex and 1x 6Pin to 4x SATA with angled connectors. Last up are 2 cables with 8Pin to 2x PCIE 8Pin, with one connector each being a 6 + 2 connector.

As a small drawback, I would like to mention that the cables are unfortunately not sleeved, which could be quite expected in a power supply of this price range. For explanation: cable sleeving is the term used when the cables are covered with a fabric-like net in addition to the plastic sheathing, in order to prevent injury to the insulation.

Deepcool DQ850-M-V2L Test – Packaging

In addition to the cardboard box, the case is delivered in a cloth bag that is sturdily padded in foam, so transport damage should only occur in case of extremely improper transport. The cables have a second cloth bag as a storage option, this is also helpful later with the modular design to store the unneeded cables together in the cabinet so that you can easily find them again bundled.

Additional content

As a small bonus, a bag of case screws for installation and also some cable ties are included. This is not a big extra in terms of value, but you would miss them if you did not have them at hand during installation. This is a case of thoughtfulness and not saving money at the wrong end, as some other manufacturers unfortunately like to do.

Deepcool DQ850-M-V2L Review – Conclusion and rating

For this price, you would have to look longer to get an equivalent and similarly well-equipped power supply. Deep Cool offers a high-quality and reliable power supply here that you can simply install and not have to think about for many years afterward. For the lack of sleeving of the modular cables, there are minimal deductions in the B grade, but otherwise, I can recommend the DQ850-M-V2L without hesitation.

The price is, depending on the dealer, with about 110 to 130 €/$ for an 850W power supply with these data rather in the lower mid-range. And for that, you get a very solid and durable power supply, where even in the long run you don’t have to worry that the expensive hardware it powers will eventually break as a result.

Over the last 40 years, I’ve had a few hundred power supplies in my hands and many of them in continuous use as well, few have made an impression as good as the Deepcool DQ850-M-V2L right off the bat. Therefore, I give this unit a 90% basic rating. However, I subtract 2% again for the missing cable sleeves, so we end up with a 88% rating.
