Energy efficiency certification

Deepcool markets the DQxxx-M series as their 80 Plus Gold power supplies. Certification is performed by an organization called (yes, you guessed it right) 80 PLUS. But what does this “on paper” mean? It’s a program that was introduced in 2004, and intended to promote efficient energy use in computer power supply units (PSUs). Only products that have more than 80% efficiency at 20, 50, and 100% load, and a power factor of 0.9 or more are eligible. This means that the PSU will waste 20% or less electric energy as heat, reducing power consumption and bills as compared with less efficient designs.

80 Plus test type	115 V internal non-redundant				230 V EU internal non-redundant
Percentage of rated load	10%	20%	50%	100%	10%	20%	50%	100%
80 Plus		80%	80%	80%		82%	85%	82%
80 Plus Bronze		82%	85%	82%		85%	88%	85%
80 Plus Silver		85%	88%	85%		87%	90%	87%
80 Plus Gold		87%	90%	87%		90%	92%	89%
80 Plus Platinum		90%	92%	89%		92%	94%	90%
80 Plus Titanium	90%	92%	94%	90%	90%	94%	96%	94%

As you can see above, there are 80 Plus, Bronze, Silver, Gold (these three are from 2008), Platinum (2009), and Titanium (2012) certificates. Nowadays most computers with a single GPU don’t need more than a 600-650W PSU, as power consumption has dropped over the years. The PSU tested today is the most efficient at 50% load (375 W), but the differences above and under this value are not significant. You don’t need to keep it exactly at half load, but for better noise performance, longevity, etc., it’s better to stay below the maximum wattage. The reviewed sample is 80 PLUS GOLD certified - up to 87~90% efficiency (at 20~100% loads), and has active PFC with a power factor of up to 0.99. It consumes < 0.3W in its off-mode, complying with the ERP standard. If you want to check the Deepcool DQ750-M’s measurements taken by the 80 Plus organization, you can look at this and (in detail) this link.

Deepcool CG560 chassis review
This time, we’re checking out the Deepcool Gamer Storm CG560, an airflow-oriented mid-sized ATX tower PC chassis. It has been introduced to the market together with a CG540 model; the main difference is that it has a tempered glass front panel. But getting back to the CG560, what does it offer besides implementing a design using the vent that should allow better airflow?
