Operandi posted--Quality is far more important then quantity when it comes to PSU's. I?ve never heard of Sintek so I can only advise you not to buy it. Stick with reputable manufactures, Seasonic, Forton, PCP&C, ect.
That would be good advice had Sin-Tek had a bad track record!!
As it is I have been impressed with what I have been hearing!!
But with that said-- instead of telling you NOT to buy something because said person knows nothing about the product--or because the product has a limited track record...
You must remember all companies had to start somewhere.....
If you check there website out you will see it appears to be a solid and impressive start!!
I would advise you to take your time and check Sin-tek out!!
As I said I have been impressed by what I have been hearing.
But.....those other brands such as Seasonic, Fortron...etc....they are good brands also!!
Yet with that said....the only one of those brands that I have personally heard nothing bad about is PCP&P!!
Good Luck in your search!!
