DeepCool PQ-M ATX 2.4

If you are building a new PC or upgrading an existing one, you can count that DeepCool will meet your expectations regarding high quality, quiet operation, and high reliability. The PQ850M is a PSU that combines all the best features to give gamers and power users the best.

Today we’re putting the new Deepcool PQ1000M power supply on our test bench. The company is rather known for making the chassis, coolers, or fans, but two power supplies were already covered on guru3d. The first one was the DQ750-M back in 2018, a 750 Watt unit with an 80 Plus Gold certificate that earned the “Recommended” award. The second one was the DQ850-M-V2L which was reviewed in 2020, bringing, for example, the 10-year warranty (instead of 5-years), but on the other side – it was rather noisy in low-mid load. Another two years have passed (coincidence?), and the next unit from Deepcool is in our hands, again with more wattage (it looks like a rule).

DeepCool initiated its cooperation with Seasonic with the PQ-M series. The Seasonic Focus Plus Gold, or GX, platform is used. While quite good, it does not meet requirements everywhere, including for Alternative Sleep Mode support and transient response, with the latter being of immense importance. Moreover, as with the Seasonic TX-700, there is a notable voltage drop at +12 V during one of the turn-on transient response tests I conduct, more specifically the PSU Off To Full +12 V test, where a full load is applied the moment the PSU is turned on. The voltage drop at +12 V can lead to compatibility problems with mainboards. Seasonic should closely examine this problem to address it as soon as possible.
