Looking for a safe reliable and durable Power Supply Unit

Solution
Tier 1 and Tier 2 PSU's are known for their safety, reliability, and efficiency. But that does not preclude you from backing up your file system regularly in case something happens.
Why are all having 750w? What are you using , or intending to use? From what you wrote there corsair seems to be the best?
Gtx1050(ti)/rx460 - https://pcpartpicker.com/product/4Vzv6h/seasonic-power-supply-s12ii430b
Gtx1060/rx480/rx470 - https://pcpartpicker.com/product/fZyFf7/seasonic-power-supply-s12ii520bronze
Gtx1070/1080 -https://pcpartpicker.com/product/gYMFf7/seasonic-power-supply-s12g550
These would be the best cheapest PSUs but they are very good , stable and offer best perf/$. Going into 750w without an sli is pointless.
 
From the PSU Tier List and Reviews:

1.Corsair CS 750M --> Tier Three (OEM: Great Wall)
2.Cooler Master V750 --> Tier One (OEM: Seasonic)
3.Antec EDGE 750 EC --> Tier Two (OEM: Seasonic)
4.Tt Toughpower Grand RGB 750W --> Tier Two (OEM: Sirfa/Sirtec)

Among the four choices about, I would go #2, #3, and #4 (in that order). I will eliminate #1 in the choices.
 



If I go for thermaltake would I be in risk? It does have 10 years of warranty but It doesn't matter because if it somehow burns my motherboard/cpu or my precious HDDs. Only want it for RGB 😀
