However, both NVIDIA and AMD are slowly phasing dual GPU tech because in reality, most gaming system don’t need to have two videos to renders beautifully these days. That is plenty of power for a SLI/Crossfire setup. And to ensure consistent power delivery on such mid-range gaming PC, the CS750M for example, is designed with 62A on the +12V single rail.

So Corsair mixes up the ingredients and brings forth the CS series - an excellent blend of both world at an affordable cost.ĬS-series has 80-Plus Gold power rating, semi-modular cable management, thermally controlled fan that doesn’t pick up much noticeable noise (max at 24 dBA) until system is over 50% load.

On other hand the TX series coming up next is a professional power supply that runs a little more quiet, all Japanese capacitors and labeled 80-Plus Gold but of course it’ll come with a price. Gamers in particular, will be having a hard time to pick out a reliable, sufficient-wattage power supply that doesn’t really break the bank.Īs you have seen, the the GS series above is a great power supply for gaming system but it doesn’t have very good energy efficiency and is non-modular. Second tier capacitors.As the gaming industry continues to grow, the hardware market will always be flooded with new PSUs from every corner of the world.

Please read the power supply reviews for detailed descriptions of problems and issues. Out of spec ripple and noise suppression. There may be additional brands and models that would qualify for the psu lemon list but they are not listed because they were not reviewed or subjected to rigorous testing. NOTA BENE - Only brands and models that were reviewed and tested by competent hardware review sites are listed. To find a high quality power supply for your computer that is safe, stable, and reliable please check the Power Supply Recommendations List. The PSU Lemon List includes descriptions of problems found and links to the hardware reviews that discovered the psu problems, issues, and flaws.
