    I am not an expert in pc building but this psu is working so far. Mostly this is a review for the provider as I had ordered one which didnt end up working, not sure if it was the psu or my computer, but the return process was very easy and they were quite communicative. I recieved a replacement in a timely matter as well.

    Goes in the A tier list of Power supplies that Linus Tech Tips has included. Got it for a heavy discount on Prime Day and just could not say no to it at that price point.

    I dont have any complaints about the product. I have been using corsair power supplies on all my builds for about 8 years. The one this one replaces was a 600 watt that ran constantly for 5 years and it is still running it just couldnt keep powering that rig after I made some upgrades to it. So I added this 800 watt to it. I liked the price and sometimes I wonder if my PC is even running because it is so quiet. I recommend this power supply as I recommend all corsair products.

    I have what I guess is the previous version of this power supply. Ive owned it for about a decade now and its worked without issue.

    Works perfectly, the white cables are a nice touch for my white case and the flat cables look nice too.
