★★★★★Great power supply

I like the park modular power supply. Allows you to keep your build cleaner.

★★★★★Good budget psu!

I know it’s bronze but I’ve had this a couple years now & it’s worked great. I’ve used it with a handful of gpu’s and a couple different CPU’s. Worth noting it ran a 4080 and a 9070xt amazingly as well as a 10700k and a 14900k beautifully. No issues highly recommended.

★★★★★Great Product

Was put into my husbands PC that came from the UK. We had to swap the power supply to match the USA outlet voltage. Has been great and works amazing.
