Besides the crappy choice of caps, they're usually pretty well built PSU's, but they love CapXon, which seem to be "ready to bulge within the month" edition. Do they do it just to save a few cents per unit? Even if they used a cheap brand like L-tec I think they'd last a quite a bit longer...Although the lower end FSP units seem to have terrible efficiency which just kills the CapXon's even faster...

Re: Why does FSP/SPI insist on using CapXon in most of their PSU's?
All relatively new units I have from lower end Sparkle/FSP have all Teapo caps... The 350PN/B was phased out in favour of the 400W 400PN/B... I haven't got a hold of one yet."We have offered them (the Arabs) a sensible way for so many years. But no, they wanted to fight. Fine! We gave them technology, the latest, the kind even Vietnam didn't have. They had double superiority in tanks and aircraft, triple in artillery, and in air defense and anti-tank weapons they had absolute supremacy. And what? Once again they were beaten. Once again they scrammed [sic]. Once again they screamed for us to come save them. Sadat woke me up in the middle of the night twice over the phone, 'Save me!' He demanded to send Soviet troops, and immediately! No! We are not going to fight for them."

Well, at least that's a small improvement. Most of the ones I see are from 2008-2011 units. The FSP300-60GLS's fail pretty quickly even with a low load, and they are 80 plus with APFCOriginally posted by mockingbird View PostComment

Because they want you to also buy another power supply!Comment

Re: Why does FSP/SPI insist on using CapXon in most of their PSU's?
ATX-350PN I have from 2008+ are the ones with the Teapos... I've never seen the big Teapo "SC" bulged in them (THough I haven't tested them), only the two small 8mm 16v 1000 SC ones by the 5VSB ever bulge.
FSP300-60THN/350-THN had a single 35V 1000uF Capxon I believe... Also, the THN have two different revisions. One with the DM311 chip and one without."We have offered them (the Arabs) a sensible way for so many years. But no, they wanted to fight. Fine!

35V in a computer PSU? For what reason, other than using up space?!Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Why does FSP/SPI insist on using CapXon in most of their PSU's?
The PN an PN/B have all 10mm Teapo SC on the secondary filtering rails. With the THN model, the +3.3V rail I believe has two Teapos and that Capxon for the pi filter output. They used a 35V cap for the higher rating... It's common."We have offered them (the Arabs) a sensible way for so many years. But no, they wanted to fight. Fine!

Re: Why does FSP/SPI insist on using CapXon in most of their PSU's?
The only reason I can see using 35V on 3.3V is due to higher ripple current and lower ESR. However, using a 35V cap is complete overkill!
CapXon do not last. Period. They are the worst capacitor in any SMPS. Next to Samwha. I have pulled approx 30-40 CapXons, from KM, KF, GF and GL series, and others.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Why does FSP/SPI insist on using CapXon in most of their PSU's?
Yeah, they are pretty bad. I'll leave them if they're primaries on a non PFC PSU though. How are their solid state capacitors, are they mediocre too?Comment
