CONCLUSION

   Over the years I may not have heard the best things about power supply units manufactured by Helly Technologies but on one hand the G12 GC-850 passed all my tests without issue (rail stability proved very good, especially for a mid-tier model that is) and on the other I seriously doubt Seasonic would risk their reputation by releasing a mediocre unit in the market. That being said even though build quality is quite decent overall I can’t ignore the fact that Helly has used Taiwanese and Chinese capacitors and that clearly deducts more points from the final result. Of course, these capacitors may never fail and so I’m not being fair towards their manufacturing companies but in this market, reputation matters and both Taiwanese and Chinese capacitors simply don’t have the best (and consumers tend to pay extra attention to this). Noise levels are also somewhat high at load and even though this is nothing new for low and mid-tier power supply units it could deter some potential buyers (even though as always chances are your GPU will be louder at load).

   The G12 GC-850 850W 80 Plus Gold power supply unit currently retails for around USD145 inside the USA and for 104.10Euros inside the EU (Amazon.de) a price tag which is indeed balanced for a Seasonic model. Long story short the G12 GC-850 may not be award winning material but it does perform well, produces quite a bit of output, has a relatively strong +12V rail and is 80 Plus Gold certified so I strongly suggest giving it a chance if you’re out in the market for a power supply unit around its wattage and price range.
