Seasonic S12 II 500W power supply supports over voltage, over power and short
circuit protection in order to protect you, the power supply and the PC
system from damage. The S12 II 500W is designed to operate in temperatures
between 0-50 degrees Celsius and in relative humidity between 20-80%.
Removing the top cover is as easy as undoing four
screws. One is hidden behind the warranty sticker, which means Seasonic
will know that you've opened up the power supply if you try and return
it. The 120mm ADDA AD1212MB-A71GL 12V fan is detachable and can be replaced
quite easily if its bearings eventually dry up and the impeller seizes. The fuse is not
In the motherboard world, capacitor reliability has
become a worrisome issue for many users. A couple years back the whole leaking
and exploding electrolytic capacitor issue wreaked havoc, and
continues to this day to show its bulging, bursting, electrolyte leaking face
on older motherboards. If you've ever had weird computer instability problems
all of sudden, odds are good it's a burst
It is hard to say how much this issue impacts power supplies, but as motherboard manufacturers are buying millions of the conductive polymer aluminum solid capacitors (a more reliable part at elevated temperatures), the price had come down enough that power supply vendors can utilize the technology has well.
Seasonic utilize one conductive polymer aluminum solid
capacitor for the 12V rail on the S12 II. It claims this will deliver higher voltage stability and reliability in the long term. If true, it could yield better performance to enthusiasts overclocking their PCs. Whether this truly makes a difference we're not sure.... but using higher quality components is a positive aspect. The remainder of the capacitors in the S12 II range in manufacturers, but of note is one Japanese made Rubycon.
Power load tests are up next.
