Looks like a decent budget power supply
I bought this after looking at ztt builds. Power supply is pretty good with sleeved cables. It's a breeze to build back in my corsair spec 01. Currently using r7 5700, GTX 750ti. Will be upgrading to rx9060xt

Smoke came out of the power supply and did'nt get refund/ replace
Very poor service, I was building a pc and ordered every item from the Amazon store but processor was missing in the box and i didnot get the chance to Check the Power supply as the refund of processor took 7 to 8 days and again i had to order Processor and took 3-4 days to come and when i finished the building power supply was not working, there was something Wrong in the cpu cable and smoke came out of the pcu, when i talk to customer care they Said that they cant do anything on this issue as the 7 days warranty window closed, In whole tragedy i lost my 4000 rupees, So go For a good brand and trusted power supply, because of the MSI i bought the pcu but i regret. 💔💔
