Allan 'Zardon' Campbell May 30, 2012 Featured Announcement, Power Supplies

The 135mm SilentWings 2 fan. This fan is a fluid dynamic bearing model with copper core. The fan is decoupled from the case which helps reduce vibrations and subsequent noise. This fan is rated to 1,500rpm with 0.22A of current. It demands 2.64W and produces a maximum of 62.74 CFM.

The design of the Dark Power Pro P10 550W is exceptionally clean with multiple rows of small black heatsinks separating the components. This supply is a new power conversion circuitry topology design. This particular model in the range is half bridge LLC resonant converter with DC to DC voltage stepdown.

The daughter PCB contains a control IC for the protection circuitry. The EMC/EMI filter is set to ensure immunity from radiation and conducted emissions.

The DC to DC daughter PCB handles the conversion to 3.3V and 5V from the 12V DC. Next to the main transformer is the OPP control coil for current detection.

The primary capacitors are rated 220uF, 450V. All capacitors in the unit are Japanese high grade, 105c rated. The power supply has OCP (over current protection), UVP (Undervoltage protection), OVP (Overvoltage protection), SCP (Short Circuit safeguard), OTP (Temperature Safeguard) and OPP (overload protection).

Almost 2/3rds of all Cyberpunk 2077 players are on PC

Despite its ubiquity across multiple gaming platforms nowadays, CD Projekt Red has always been a PC-centric studio, with the original The Witcher being a PC exclusive and its sequel coming only to Xbox on the console side. Despite selling millions upon millions of copies of both The Witcher 3 and Cyberpunk 2077 across PlayStation/Xbox since, new data has revealed just how much of the audience still hail from CDPR's home platform.

    Their products always look great. This is a little costly for a 550W however, id be aiming to get 750W at this price, even without all those lovely extras.

    Ideal for a media center, but again, its rather expensive for a 550W, even if its gold.

    Heck of a bundle, but I dont think id buy a 550W anymore, id be aiming a few hundred watts more, just for some futureproofing.

    Its a common mistake that people think every PC needs 800W+ a 550W can handle two graphics cards (not the high end power suckers obviously) and a decent system.
