Picking out a power supply is not something that should be taken lightly. In a literal sense, weight is one way to determine if a PSU is up to snuff or not, but you also need to factor in how much wattage you need and how it's distributed -- today's systems rely heavily on the +12V rail(s). The easy way to figure out how much power you need so you don't overspend is to use eXtreme Outer Vision's recently updated online PSU calculator.
Putting together a modest system that doesn't require a nuclear reactor to power up and sustain during gaming sessions? EVGA might have what you're looking for. The hardware player announced a couple of new power supplies -- a 500W model and a 430W model, both aimed at budget builders who aren't looking to spend all their holiday skrilla on a PSU, yet still want a name brand unit.
Affected models were sold prior to October 1, 2013
EVGA today issued a notice to customers warning that some of its SuperNova power supplies may suffer from a manufacturing defect. Affected units are prone to shut down at any given time and/or may refuse to power on. According to EVGA, the issue only affects a "small batch" of 1300W and 1000W PSUs, including the SuperNova 1000 G2 (120-G2-1000-XR), SuperNova 1000 P2 (220-P2-1000-XR), and SuperNova 1300 G2 (120-G2-1300-XR).
Flat ribbon cables and 80 Plus Bronze certification
Cooler Master this week expanded its line of power supplies by introducing its new GM Series under its gaming umbrella. Billed as being "efficient and valuable," Cooler Master says these new PSUs boast better efficiency and improved heat dissipation thanks in part to being manufactured with a unique 3D circuit design. The GM Series also boasts semi-modular cabling with flat-ribbon cables.
OCZ is still making the most of its relationship with renowned gamer Johnathan Wendel, otherwise known as Fatal1ty, the name you'll find on the side of OCZ's two newest power supplies. Available in 550W and 750W models, these Fatal1ty PSUs feature a brand new core and are quieter, more energy efficient, and easier to manage thanks to a completely modular cable design.
New 80 plus gold and 80 plus bronze PSUs announced
LEPA Technology announced new power supplies in the GM MaxGold, BM MaxBron, and MX F1 series, which range from a modest 350 Watts up to a more robust 1,000 and targets everybody from entry to enthusiast-level computer builders.
The GM-MaxGold and BM-MaxBron are both semi-modular power supplies. They feature a special Anti3s Q-Brick design which is a protective sleeve designed to protect from static, shock, and slip. This protective sleeve comes in two colors, red and black. In addition, both lines boast an improved DC-to-DC converter which improves stability in C6/C7 sleep modes. This ensures full Haswell support for low power sleep states.
Silence is golden, or in this case, 80 Plus Gold certified
Corsair on Thursday added a new line of quiet power supplies (PSUs) dubbed RM Series to its product portfolio. These are intended to replace the TX Series of PSUs while adding 80 Plus Gold level energy efficiency, whisper-quiet operation, and monitoring capabilities, Corsair said. Even when delivering high levels of power, Corsair claims you'll hardly hear a peep out of its RM Series.
Unique software solution keeps track of energy costs
Thermaltake has come out with a new kind of power supply (PSU), one that will let you monitor and control its vitals to provide your system with clean and stable power, and to help you keep track of how much juice it's sucking from the wall. The new units are the Toughpower DPS 850W and 750W, both digitally controlled via a free software download (DPSApp) available on Thermaltake's website.
The power supply might be the single most under appreciated component in a system build (don't go generic, folks), but at the same time, that doesn't mean you should overspend on way more power than you need. If you're putting together a budget build, EVGA hopes you'll consider its new 600B, a 600W PSU with 80 Plus Bronze certification, meaning it's over 80 percent efficient at typical loads.
After achieving 80 Plus Gold certification for its original Supernova 1000W power supply (1000 G2), EVGA is back with a newer revision that now boasts an 80 Plus Platinum badge, meaning it's a little more efficient than its predecessor. The new Supernova 1000 P2 features 92 percent efficiency under typical loads and has a new "ECO Thermal Control Fan System" that supposedly eliminates fan noise during load operations.
