GAMEMAX 850W Power Supply, Fully Modular, 80 Plus Gold, ARGB SYNC with Motherboard, RGB-850 Pro

Just install this power supply into any computer, and boom! Anybody within a 500-foot radius will hear the loud noises from the power supply, shriek, and run far far away. My house is now free from all mosquitoes, termites, cats, annoying roommates, and more! (Detailed version) I was building an AMD RGB computer for a friend on a budget, and I was looking for a cheap PSU. This was one of the cheapest power supplies I could find on Amazon for this price point, so I went ahead and purchased it. The installation was easy; the PSU has worked flawlessly for her so far. I loved the look of the PSU in her computer, and at that time the PSU in my computer was starting to fail. I bought another GAMEMAX PSU for myself. Initially, the PSU worked great. It looked awesome in my RGB computer case, and it shot out tons of air out the back. Over time, though, the PSU started having problems. The fan would vibrate, stop, and make a high-pitch buzz, and my computer would frequently crash. As I was still in the 1-month return period, I gave GAMEMAX the benefit of the doubt and returned it, replacing it with the same PSU. My second PSU (that I am using now to type this review) hasn't had the same issues as the first. The fan still makes the vibrating noise (it must be typical for this PSU) but I don't have frequent crashes. Overall, 2/3 of these power supplies have worked for me. I would recommend this if you are on a strict budget but not if you can afford a PSU from a more reputable brand. Additional note: the PSU's eco mode is a button switch and not a flip switch. Eco mode cannot be permanently turned off; it always turns on every time you boot the computer up. [Update] I just bought another one of these PSUs for a different computer and that one works fine; now 3/4 of these have worked for me. Several of them are still emitting very annoying noises, and I believe they are coming from a faulty fan. I wouldn’t recommend these for anybody; save up and get a better PSU instead.

It runs really well and I like the LEDs!

This is a pretty awesome power supply. It is perfect for any gaming rig provides that your power supply slow is not on the bottom. The reason being is the fan for the power supply is on the bottom so if you have a power supply slot on the bottom, you cannot take advantage of the RGB lights. That being said the RGB lights are absolutely beautiful. It blends very well and if you do not like the lighting you can actually turn it off which is nice. The fan is not too loud. It keeps at a pretty good noise level. It is not dead silent but it's not too heavy on noise that you will notice it. This provides 600 watt worth of power which is more than enough for more gaming rigs short of powering two graphic cards. In terms of connection, there are several connectors. Unlike many other high end power supplies you cannot remove to make cable management easier. There are several connectors. The main motherboard and cpu connector are always a must. There are five sata ports, three molex and two pci-e plugs. The pci-e ports are connected to the same wires. What is nice about this is that the PCI-e and the CPU cables are color coded so you can tell them apart easier. The CPU port is red and the PCI-E are green so you do not get them mixed up when trying to plug it in. It was able to provide my gaming rig with all the power it needed. I am running an i7, 1080 TI, 16 GB of ram and several hard drives and it runs pretty well without issue. The power supply does not get too hot or anything so you do not have to worry about it burning out. The cables are all long enough to work well in a full size tower and all the connector are secure. Overall I think this is a good power supply for any gaming rig given you are not running more than one GPU. It has an option of controlling the LED lights and is not too loud. It comes with the four mounting screws and the standard power cord which feel a little flimsy but it works. The light show is nice and not too bright. If you have an RGB gaming rig this is definitely going to fit into the theme.

This power supply was the perfect fitment for my Custom PC I built. Nice quality...

**UPDATE 2/22/2021 - I ended up disputing with my credit card servicer to get my money back. PSU is still a POS and doesn't even make a decent doorstop. Pulled the PSU apart and the filters are cheap Chinese garbage and are bulging from the bottom. Decided to use it for target practice instead. **UPDATE 12/30/2020 - I replaced this power supply with an ACTUAL 80+ Bronze Cooler Master PSU. Resolved all my issues i had with stability and random shutdowns. I looked into the chassis of the PSU and the caps are bulging. It smells horrid (like ammonia). The company is impossible to get ahold of and they have not responded to my emails nor my calls (they have a foreign number, and i used a Cantonese speaking friend to translate. No response. Only buy this if you're willing to risk damage to your components. I thought I would cut costs with a new build (Ryzen 7 2700 & RTX 2070 with 32GB 3600mhz RAM) since this power supply said it was 80 Plus certified. Worked great and noticed that it “almost” reached the same core clocks that my older TT power supply had. After a while the overclocks became more unstable and I kept pulling the frequency back for cpu and gpu. Now the power supply just cuts off randomly. It will drop voltage significantly to the CPU 8 pin and then cut off. Tested with multimeter and another power supply. Seems like the components used aren’t built to last. I will eventually pull it apart to see if I can see bulging filters. NOTE: I had this power supply pulling fresh air from the outside of the chassis from the bottom with ample space. I’m in a non-smoking house with pets. The power supply air intake is filters with a mesh filter I installed. There is no dust choking the intake (pertaining to this review) I would avoid this product. It was also disappointing it has two pci e spots for gpu/addl cpu but they only provide one cable for pcie power. Save yourself the trouble and spend a little more to get a way better deal. There isn’t even phone support in the United States. You have to call out to Asia. Installation was okay but the connectors are cheap and will chip ( happened to two of my sata connectors and had to tape them with electrical tape to prevent shorts). The clips to lock onto the female connector also are weak and you have to force them to close and ‘’marry”. The RGB effect isn’t controllable except for turning it off (you hold the ECO button for 5 seconds) but it won’t hold that setting after you turn off the pc. Same with the ECO mode. Please avoid this power supply.

So unfortunately my tests weren't as thorough is I wanted. I could not find my wall meter or temp gun. I tried to make this as technical as I could anyway. System: Asus x99-Pro/USB3.1, Xeon e5-1630v4, 8x 4gb DDR4 2666mhz, XfX RX580 GTS Black, Samsung m.2, and some generic cooler since I usually run a AIO. First off, there had to be some changes to the test bench but I ran the unit on various stress tests to include Aida64, TimeSpy, and the Furry donut. After hours, the system continued to run with no issues. And I was still able to handle PSU since the unit never got warm at all. However, this is where not having my wall meter creates a disadvantage. I wanted to use a power hungry system to push this unit, but I went overboard at first. I originally had a Vega 64 on the bench, but the system would not boot completely. I am not faulting the product for this since the original setup would come in at around 600w and that is the limit of the unit. If anything, the system not booting could be a good example of the PSU's fault protection. But without knowing how much power the system was pulling exactly, this is debatable. Everything else I was pretty impressed with. The fan does spin according to load, so it helps keep things quite when not being used heavily. The eco-mode button does work and isnt a useless gimmick. When system was idle, and in eco mode, the unit would cool off and become silent. Build quality seems to be on par with more "prestigious" brands, minus the thin bars used as a grid to protect the fan. They will bend with moderate pressure, and since its a RGB model its clearly designed to be installed fan up. So dont drop anything on them while building. Other than that, the house is incredibly sturdy. The wires used seem more than capable to handle the loads, and aren't to stiff to work with. They could be better, but I'll get into that later. One stand out here is the ease in which the plugs fit into place. Each one went into their sockets smoothly without having to apply so much force you worry about breaking the motherboard. Yet they stay in place snugly and take just as much effort to unplug as they do to plug in. I'm actually understating how much I loved this. The fitment is amazing. The plugs also lead into my complaints though. The wires are colored. Or "ketchup and mustard" wires as more known reviewers call them. Not only are the wires colored, the plugs are too. So to use this in a build, you now have to factor a red CPU plug and neon green plug into your color scheme. And at coming in at around 19 inches long, these cables are relatively short. Using the unit in a larger case would mean that they probably won't reach if traditionally cabled managed. Especially the CPU cable. But these semi-modular/modular units are usually more suitable for smaller builds. So its definitely something to note. At first I was pretty unfazed with this downside. My original thought was that it would be great news for sleeved cable extensions. With less length getting in the way. It would even fix the red and neon green plugs. But when you factor in that these extensions are an additional $25-30, its definitely something to ponder over. All in all, I'm happy with the unit at this price. Especially since it IS semi-modular and RGB. Right now I give it 4 stars. If they were to use black plugs and wires, I'd give it 5 stars all day long. Though this is dependent on what happens when I find my wall meter. I'll update once I do. *Update - found my wall meter and all is right the PSU. The system was pulling way to much on boot and the PSU was safely preventing itself.

Pros: -Silent operation. -Modular design keeps things simple and organized. (Had every wire I needed plus a bunch extra that I didn't.) -RGB is a nice addition that gives my PC some character. (Mounted it facing downwards and it gives my case some underglow.) -It comes with a tester to make sure that it functions which came in real handy... -Wires were clearly labeled and practically impossible to get the wires wrong... (but...) NOTE: (<not a con, the PSU is pretty solid) -I messed up on the wires... It was purely human error and inexperience on my part. I did not, apparently, insert the wires right the first time... I think there might have been a 3rd. I initially thought that I had received a bad product despite the tester activating the PSU. <It was either that or the motherboard. But! I did eventually get everything going. Found out, you can't really mess up the wire installation as they are clearly labeled and only fit into their assigned slots, however, you've got to ensure that they are plugged in securely and that the GPU wire (which has a separate piece to the GPU side plug-in goes in right. <Small part first, then larger part. If you are having trouble with it, try taking the wires out and reinstalling them as you might be having a similar issue as I had.

Item works like a charm. Purchased a separate tester prior to replacing my old PSU and it held steady for 48hours straight. Time will tell how durable it will be and will change my review then. Came in with all the cables you will ever need. NVidia 40 series + ready as well.
