Hi friends,
I am planning to buy a Seasonic S12ii 520w but I have come across multiple threads telling the need for a pure sine wave UPS to support it. This has me confused so should I buy a very costly pure sine wave UPS (not possible) or should I go for a less reliable PSU like corsair GS600 and an APC 1.1KVA UPS?
Waiting for your suggestions.

PS: Total budget for UPS and PSU is 10k.

I am more interested in GS600 is there any problem with it. But couldn't get any proper reviews compared to Seasonic. Are there any pure sinewave ups for 5k.

go through this thread first:
*www.digit.in/forum/power-supply-cabinets-mods/191220-need-ups.html
btw this cyberpower ups is also "simulated sine wave" not "pure sine wave" which as you said are very expensive.don't read too much over internet as you will never find a conclusive answer only confusion.buy seasonic psu & apc ups & if something goes wrong rest assured it will not be because of "sine wave".

Ya man I really wasted 2 days about the issue but only got confused.
Problem is the assembler asked me to get the Seasonic in flipkart so don't know whether to risk buying it.
Ur Advise on it.

it is your money so your choice but if i had the money to buy i would buy this seasonic psu & apc "smart ups".just go through the above thread & buy only from a reputed/experienced seller even if the price is a bit higher.also buy ups from shop if possible even if it means a 3-4 hour journey else order online but i don't trust much courier compnies for heavy electrical items like ups especially if delivery is in a small town or remote area(delhi,bombay,bangalore etc are fine).

What abt Corsair GS is it reliable?
Even Antec VP series seems to be gd?
Just don't want any headaches after buying these beauties.

like i said your money your choice,even apple products fail so there is no guarantee you won't get any headache after buying any of these.general consensus seems to be seasonic>antec>corsair.

No man still didn't complete the assembly. Planning for APC 1.1kva same as you.
A small doubt is your UPS compatible with PSU.
