is this refurbished psu?

[ipo3nk]

i found few model of seasonic that quite old still on sale in my country.
the seller says that the psu is new non refurbished.

but if i look in detail, all of them had old manufacturing date on their parts
the tranny, capacitor & semiconductor date code too old for a new psu.

check this out.

it cost USD82$ listed for 600w
tranny date code 0809, (year 08, week 09)
like excact copy of tx650? including the manufacturing date!
if you search the batch number in capacitor, it also says 2008 parts.
afaik, psu makers never stock capacitor in large number..




it cost 52usd for 400w.. full range input.
this is the value line, like antec earth watt model.
including the date code, 0910..
still using champion micro pwm/apfc controler..




this is the new budget line from seasonic that also sell in here.
parts made in 2012.. i'm sure this is non refurb psu.
s12-ii with infeneon pwm/apfc controler..
the price is 54usd, 220v only..


what do you thing about the first two?
is it refurb psu? worth to buy?
for comparison new s12ii 520w cost 70$

Possibly. I occasionally see NOS stuff much older than that

Re: is this refurbished psu?

You wrote that the s12-ii is $54, then you wrote that it's $70, which is it? At $54 I would prefer it, but if it is $70 and the PC that the PSU is going into uses nowhere near 400W, then I would consider buying the new old stock 400W PSU, BUT look at the brand of capacitors used on the output, it is the best indicator of which will have longer life.
