Deepcool DQ750 Quanta Semi-Modular Power Supply Review

Final Thoughts


We cannot find Deepcool’s DQ750 power supply listed at any major retailers in the UK or the USA, a little strange but we assume the fact this product is quite new is the reason for this: it has yet to make a proper retail landing. Deepcool claim an MSRP of $129.99 on this unit but we’re not sure how this translates into actual retail pricing. At the sub $130 price point there is a huge array of 80 Plus Gold rated 750W units with better features or better pricing. Deepcool need to land this unit on the shelves at around $110 to stay competitive in my opinion. Deepcool offer a 3 year manufacturer’s warranty with this product.


The Deepcool DQ750 is a solid power supply unit. Our testing has revealed strong voltage regulation and efficiency are the main selling points of this unit. Ripple suppression is fantastic on the 3.3 and 5 volt rails but is less impressive on the 12 volt rail: especially given the price point of $130 that Deepcool occupy. The unit does have some nice features with all-black cables and an LED fan but there’s also a fair amount missing. There’s no fully modular design which is a negative for the price point and there’s also no LED switch to turn off the LEDs if you so desire. For the wattage it also feels like this unit is lacking in cables: more SATA connectors are needed and there’s no FDD option, both of which are needed to match rival offering.

With retail pricing and availability being so scarce it is difficult to come to a concrete conclusion about the Deepcool DQ750. If it arrives at $100-110 it would make a solid buy, but at $130 which is the only price we have to work with I feel that not enough is offered. There are too many rival units offering better connector selections, fully modular designs, hybrid fan modes and more: all things this unit doesn’t have. As I write this Corsair, SilverStone, Antec, Thermaltake, XFX, Seasonic and Rosewill all offer lower cost power supplies that do the same thing, if not slightly better. Deepcool’s entry into the power supply market is certainly a good start but I can see room for improvement.


  • Strong voltage regulation
  • Excellent 3.3 and 5 volt ripple suppression
  • High efficiency
  • Quiet operation
  • All black cables


  • Too costly
  • No LED on/off option
  • Not fully modular
  • Not enough SATA connectors and no FDD
  • No user manual online or in physical form

“The DQ750 is a solid starting point for Deepcool’s entry into the world of consumer power supplies. If Deepcool can get the pricing right this unit promises to be a strong contender in a highly competitive market segment.”

Thank you to Deepcool for providing this review sample.
