As usual MSI has come to the party with a great quality, value for money product that is hard to beat! This PSU has everything I need and more without breaking the bank, this is why I have brought and will continue to buy MSI for years to come.

Very good product, nice looking and good and stable supply on all the different voltages.
Full modular system makes the cables tidy and organized.

bought this to replace a 850w supply that failed, - which turns out two usb ports had failed on the motherboard - which took out the power supply,
so, the bottom line is, this new supply is the same power and specification and,

it's shorter in length, same width, so it fits alright, the price was reasonable and it was delivered overnight - which is great service by PB Tech,
I expect it'll work ok, once I've procured a new motherboard, bought this to replace a 850w supply that failed, - which turns out two usb ports had failed on the motherboard - which took out the power supply,

Great price and size. was worried that it wouldnt fit in my case but it ended up being smaller than i thought and works great for cable management and isnt loud !

Great product, works well, more than enough power for my GPU Great product, works well, more than enough power for my GPU

Using a RX 9070 and a AMD R7 9700x and they work perfectly Using a RX 9070 and a AMD R7 9700x and they work perfectly

Totally worth the money! It works seamlessly with my system, runs smoothly for hours without overheating or crashing. Totally worth the money! It works seamlessly with my system, runs smoothly for hours without overheating or crashing.

Works great, its quite, and it can keep up with my 4070tis so no complaints from me. Also the addition of the GPU power cable direct from the PSU makes a lot more sense then those unreliable 16pin connectors that came with GPU.
