The DW1250's most notable advantage, most likely the decisive factor in its purchase, is that it manages to combine high capacity and efficiency with a fairly silent operation at, especially, light- to mid-level loads under normal operational conditions. I have to stress here that this feature is not to be taken lightly because such highly efficient PSUs of high capacity very rarely use a relaxed fan profile as manufacturers prefer to be on the safe side instead of having to deal with a huge number of RMAs. The DQ1250 managed to survive all of my incredibly tough tests and operated flawlessly even while the ambient inside my hot box reached 47°C over prolonged periods of time, which reveals a lot about its reliability, and the provided five-years warranty is another tell-tale sign of its high quality. Since this is Deepcool's first foray into the high-end PSU category, not everything is well, with the most significant oversight being its really thin AC power cord, which can be a fire hazard if you plug the PSU into a 115 VAC power grid, where the PSU will draw more than 10 Amps from the socket at full load. I don't understand how this matter passed under Deepcool's radar, and I strongly advise them to change it immediately by replacing the provided cord with a thicker one and offering a replacement to those users who already purchased the unit. I liked the PSU apart from its cable since it managed to perform very well throughout and is probably the quietest high-end PSU I have ever tested.

If you hate noise, but still need a very strong PSU, this one is the one for you. Just make sure to buy another power cord, or keep a fire extinguisher close, especially if your mains grid provides 115 VAC. Such a serious issue aside, for which I deducted several points, I found the DQ1250 to be a really good PSU Deepcool is currently selling for a nice price. Deepcool is on the right track, and I welcome their effort in this tough market segment.
