I'm sorry for bumping a old thread. But when doing research on the Gamemax RGB 850 this is one of the first things that comes up.
I bought one during that period when PSUs were hard to get because everyone wanted a new one for the RTX 3000 series (if only I had known I wouldn't get my turn on EVGA's waiting list till late Sep 2021!). Anyways I got the email from EVGA and bought a RTX 3080 FTW3 Ultra. Before that I had a EVGA GTX 1080 SC. I have an 8700K OC @ 4.7 Ghz all core, 2 PCI-E NVME SSD's, 2x 3TB 7200 RPM HDD's, and 3 140MM Be Quiet case fans.
The PSU worked perfectly when I got it. I was never able to hear its fan no matter if I was gaming or running some sort of CPU/GPU burn in program. I was also quite impressed with how quality it felt from the get-go in terms of packaging, presentation, feel etc.
However, once I got my RTX 3080 FTW3 Ultra it's now giving me a problem. It gets REALLY loud when I play any game. Within 1 minute of launching a game the PSU fan ramps up to what has to be it's max speed. Every PSU calculator I've used says my system most likely draws about 650W under full load. So 850W should be just fine. But it seems the Gamemax RGB 850 can't handle it.
I couldn't find anything online about others having this issue, and this PSU actually has a good number of customer reviews on Amazon and Newegg. Including people with newer more power hungry CPU's than me and RTX 3090's saying their Gamemax RGB 850 is silent while gaming.
So I email customer service. Don't hear anything for 5 days. Send another e-mail saying I'm updating my Amazon review to let people know that there is no real warranty on this product because customer service simply dose not respond.
Next day I get a reply, they claim that the e-mail where I said I was gonna update my amazon review was the first they have gotten from me which is simply not true. But in order to even get them to make a decision on an RMA I have to do the regular stuff. Order number / image of invoice, computer specs. But they also require me to record a video of the PSU and show how loud it gets. That's just crazy if you ask me.
I actually just remembered that it comes with a card stating if you register the PSU with them (which I did as soon as I got it), you get 8 years of warranty instead of 5 and more importantly 24 months instead of 12 to get "a full refund". So that's what I'm gonna tell them. I just want my money back. I got all the box and all the packaging it came in, every book, card etc. I'll request for them to make good on that guarantee. Won't be surprised if they don't though.
Oh, take the customer reviews with a grain of salt anyways, they include a card asking you to email them your "thoughts" on the product. They reply asking you to give them a review on amazon, include pictures etc. Once you do that, they claim they will send you a free RGB mouse pad. So basically, bribe you for a positive amazon review.
