Hey guys,
I just registered to the SFF Forum so I can join this conversation. I'm trying to decide between the SX700-LPT and the PE-750 as well and I had an email exchange with Baron, Lian Li's representative in the US, about the warranty and the fan of the PE-750 that I though could interest everybody here. This is the summery of the exchange:
My original email:
Hey guys,
I'm trying to decide between the Lian Li PE-750 and the Silverstone
SX700-LPT PSUs. On paper, your PSU is better (750w >> 700w !!!), but I still
have 2 issues that I need to figure out:
1) Warranty - I've been building computers for a long time now and, mostly,
I've used Corsair PSUs, which usually come with a 7-10 years warranty. While
I don't expect a company that's new to the PSU market to give that long of a
warranty period I must confess that a 1 year warranty for a PSU does make me
a bit nervous (Silverstone give 3 years warranty for their PSU). Any chance
we'll be able to extend the warranty period somehow?
2) The fan - The Silverstone SX700-LPT's fan has a semi-fanless mod, which
means it doesn't start spinning until the load on the PSU is around 30%.
Does your fan has such a mode or is it a simple PWM fan that adjusts its
rpms base on the load and temp. Any chance we can get more data (maybe a
graph on your PSU's web page) that shows the correlation between PSU loading
and fan rpm ?
Thanks guys
Baron's reply to my email:
Hi ,
(1)The Warranty is 2 years .
(2)The fan will start to spin until the load on the PSU is around 30%. However,
once it start to ship , it won't stop even the load is under 30%.
My reply to Baron's reply:
Hi baron,
Thanks for responding to my email so fast. Just to clarify and verify those
2 issues before I finally pull the trigger and order this PSU from Newegg:
(1)Are you absolutely sure the warranty for the PE-750 is 2 years?
Because on the Newegg website it definitely says 1 year. Also, in the online
review by James Schell from SFF Network
(
https://smallformfactor.net/reviews/powersupplies/silverstone-sx700-lpt-review-finally,
scroll all the way to the bottom and you’ll see it in the second bullet point) he also
mentions that the warranty is 1 year.
(2)Did you mean to say “The fan will [not] start to spin until the load
on the PSU is around 30%. However , once it start to ship [spin] , it won't
stop even [if] the load is under 30% .”?
Thanks again

Hi ,
(1)If your PSU have problem during the 2 years warranty, please e-mail us. We
will take care of it .
(2)The psu fan will not spin until the load of PSU is around 30%. Once the fan
start to spin , it won’t stop even the load is under 30% again. However, there
is a chip on the PSU to adjust the fan speed ,and the fan speed change depends
on the PSU load.
So, what do you guys think?
