DeepCool Quanta DQ1250 1250W Power Supply Review

   We may be just days away from NVIDIAs announcement of their latest desktop graphics line (GTX 980/970 models probably) so if that does happen on the 18th of this month i expect that many of you will want to also upgrade their power supply units quite soon (i expect some have already done so in anticipation of this). We have already tested quite a few of the latest PSU models to hit the market by a wide range of manufacturers but the good thing with this industry is that you always get many more to choose from and so currently there's an abundance of models with outputs surpassing the 1KW line. This is certainly not needed if you plan on using a single high-end card but if you decide on using at least two then you'd better be ready. DeepCool has left quite the mark in the industry with their very good air and liquid cooling solutions but it seems that's not enough for them since their latest Quanta line of PSUs seems to have nothing to be jealous from other similar competing solutions and the flagship DQ1250 1250W 80 Plus Platinum Certified model should be quite the beast.

   Judging by its specifications sheet the DQ1250 seems to be a solid semi-modular (only the mainboard and two ATX12V cables are attached) 80 Plus Platinum certified power supply with a continuous power output of 1250W and two strong 12V rails capable of delivering 45A and 65A peak output each. As expected from the flagship model of the Quanta PSU line DeepCool has no only used high-quality components like Japanese made capacitors but they have also installed a separate circuit which keeps the fan at zero rpm either until the power supply surpasses 30% load or the ambient temperature crosses the 25 degrees Celsius mark. We also see that DeepCool has also included the rather standard electrical protections including over voltage protection (OVP), under voltage protection (UVP), over current protection (OCP), short circuit protection (SCP) and over power protection (OPP) so the DQ1250 should have no problem providing clean and stable power to your system around the clock 24/7. Leaving out the specifications sheet however it's up to us to see how well it performs so let's check it out.
