Decent power supply with awesome RGB lightning
2025-12-17T06:58:35.206Z

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 PSU caught me off guard. I forgot to use the test before installing it. And this PSU has been flawless. Its modular wiring makes it great and 850 watts is premium for high end gaming. Nvidia cards work great on it.
