That's a 6-rail PSU. Ignore the claims in the sale ad saying it's single-rail, the sticker clearly shows it's not. You MIGHT be able to find some documentation by contacting Seventeam (I hope you speak Chinese) showing which connectors route to which rails.

No chinese here rs, I`m from Brazil

Just to finish this discussion, this is a good PSU and i made a good choice?

Can i sleep thinking that i made a good thing?

Thanks again

You're fine. =)

OP:

At ~100VAC you need thicker wires to deliver the same wattage you would at ~240VAC. This stops some high wattage power supplies from getting enough power from the socket (those use a C13/C14 connection pair). This unit uses a C19/C20 pair so it can draw more from the wall.

Now, this can also be dangerous if the wiring on your house is not very thick, or if it's old and teared and the voltage there is at ~100AC. It's possible to overload the inner cabling on the house in that case.

But you have ~240VAC there so all this doesn't matter to you.


Anyway, do not give the advertised wattage numbers too much attention. Units around the 1.2KW mark can easily deliver like 1.5 kilowatts without issues. This unit with all the thick plugs and the internal structure it has might be able to go even further.


It's quite sad that many companies that have the means to make some exotic, reliable and powerful units end up making garbage because of cost considerations. It's not just Seventeam; Fortron/FSP, Enhance, Channel Well, Huntkey all showed that they can do some great stuff in the past, yet they rarely do.

I even have the impression that Enhance currently has the most efficient budget units made for Coolermaster (that are quite crappy on the insides) and I still remember Huntkey making X7 1200 using an approach no one tried before, not to mention Seventeam making a unit with user-adjustable voltages for Silverstone in the past (I think that this Seventeam unit shares a very similar internal structure to the Silverstone).

And to answer the original question, again, this PSU is fine.

Thanks for the explanation man
