Model overview based on user reviews
The Gamemax GP Series power supplies offer a range of models suitable for various budgets and needs. Users appreciate the affordable price and features like braided cables and 80 Plus Bronze certification in some models. However, there are mixed reviews regarding noise levels, with some models being quiet under load, while others produce loud noise during heavy use. Quality concerns are noted, such as bad quality connectors and incomprehensible capacitors. Some users suggest spending a bit more for a higher-quality PSU, as the protection system can cause frequent reboots, affecting system stability. Overall, the Gamemax GP Series may be a good temporary solution for budget-conscious buyers, but investing in a more reliable PSU is recommended for long-term use.

I couldn't decide on a brand of PSU for my new PC for a long time, as there were many mixed reviews about this Gamemax. But I decided to go with the GP-400A model for a PC with a hyper processor 4560 and a video card 1060 with 3 GB, not counting the cooler, hard drive, and RAM, as they consume very little power. What can I say, the PSU is quiet, really quiet even under load, the power is sufficient, 120mm cooler, sleeved cables. I saw in some site's description that it has a modular system, but that's not true if anyone's wondering. It works, and I haven't thought about it since I installed it. The cables have velcro for cable management, the cable length is good, everything needed is there. Quiet, braided wires Not found  Viktor S.: use Gamemax GP-400A few months |
A block is like a block. But due to loud rattling under heavy loads, I was forced to change it to a Zalman TX ZM600 Price, stability Loud noise under heavy loads. use Gamemax GP-550 few months |
A good PSU if the budget is small for a while you can take Not expensive, there is a power cord Noisy! Factory defect tangled 2 wires no braid use Gamemax GP-450 few months |
