antec sp 450

[paul_h]

I have an old antec PSU I de-capped ages ago, but lost the bit of paper where I wrote down what goes where.
Can anyone help?

Here is two 10V caps IIRC, one 2200uF and one 1000uF cap, which one goes where?

Also for the power rails, I know theres a 16V 3300 on the left (is that correct?)
And there's two 6.3v caps on the right, what sizes should they be (3300uF??) and what are the two middle caps I've completely forgotten about, are they 10V / 2200uF for the 5v line??

Any help would be greatly appreciated, I removed these caps last september!
Thanks.

2200/10 on the left near diode, 1000/10 on the right near resister and 5VSB wire.

Yes, you're correct. 3300/16 on the left (12V), 2x2200/10 on middle (5V) and 2x3300/6.3 on the right (3.3V).

Thanks a lot.

Re: antec sp 450

Two 1000uf 10V caps go in the standby circuit (picture 1) 0076G.

That's the value in both my 3 Antec Smartpowers and my Antec True Power.

Re: antec sp 450

was one 10mm dia and the other 8mm for some unknown reason, even though they are both the same voltage and value?
If so, that rings some bells, I was doubting myself thinking the one was 2200uF anyway, I began to think that maybe one was 1000uF and the other one was 1200uF(not 2200uF)

[Krankshaft]

Re: antec sp 450

No both are 8mm. For example Panasonic FC series EEUFC1A102L. Larger caps will get in the way of the rear fan blades.

You can force a 10mm to fit with a bit of lead bending but it will be tight.

Re: antec sp 450

OK, thanks for that.

Re: antec sp 450

I just found my diagram, it does show a 2200uF cap on the standby circuit (closest to the inside of the PCB), and the outer one being a 1000uf cap.
Maybe I noted it down wrong, maybe that's right for my SP 2 450w, what should I do?
This is a later model SP2 450w, it's one I got for RMA exchange after the original blew, over a year after they weren't really being sold retail anymore.

edit: also with the 5v rail where I thought both middle caps were 10v 2200uF, It seems on my diagram that one was 10v 2200uF (the one closest the the cables/edge). The inner most one was 10v 1000uF

Re: antec sp 450

To me it makes sense, because I never did the recap because I couldn't get a D8mm cap the rated uF for one of the standby caps. A quick look around, and with info from krankshaft re pana D8mm, it's easy to get D8mm 10v 1000uF caps, so I think I was stuck on a 2200uF D8mm cap

Re: antec sp 450

I just fixed a Antec SP 400 and a SP 450 this week.

the main filter caps are 4700uF 16V D10mm, 2200uF 10V, 1000uF 10V.....

You can use 3300uF 16V D10mm Samxon RS or 2200uF 16V D10mm GD/GT to fixed the size problem of 16V rail.

I have repaced all caps, most of original are Fuhjyyu and seomtimes mixed with Teapo, surely both big can caps are Fuhiyyu....

Re: antec sp 450

OK, it's all in and now the PSU turns on. Voltages seem OK too.
Only thing in the outside fan doesn't run, but they may be just switched on a certain temps? The thinner inside fan with the tacho wire runs OK.

Things didn't go smoothly with the tagan. That PSU required a lot of dis-assembly unlike the antec. The antec required next to no dis-assembly. For the tagan I had to remove heatsinks. And to remove heatsinks I had to remove components like the control PCB and some coils so I could unscrew the schotts from the heatsink. And it was pretty hard to get everything back together under the heatsinks. I should have just desoldered the schotts, but my desoldering sucks and I didn't want to overheat the rectifiers

Anyway, the tagan is back together but just blows the fuse.
No bang, just quietly goes open circuit (no visible shorts either). Maybe the 5 amp fuse I have is too small (I'm on 240v single phase)? I don't have any 10amp fuses yet.

Re: antec sp 450

if you didnt remove the antec heatsinks you probably missed some small caps.

as for the rear fan - it only runs when it starts to cook.
they discontinued that model because so many people returned them thinking the fan was faulty!

[paul_h]

Re: antec sp 450

There isn't really much that the heatsinks cover on that antec.
Fan problem solved anyway. I knew one would only come on when a certain load/heat level reached, but as I said, the inside fan ran from first power on, the outside one never started, even with the system loaded and hot. Switching fan plugs and neither ran.
Got it sorted though, as one of the plugs was dodgey, and the solder pins too.
So now the outside fan runs on boot, and the indoor fan runs as required.

I'm pretty sure plenty of people, more than the kind you mentioned, returned antec PSUs for other faults besides the indoor fan.
The first antec PSU killed my entire NF2 system, then I got this one as an RMA. This one killed my ram before it died. If antec were to discontinue anything, I hope it would be horrible capacitors before secondary fans that confused people.

Anyway, they probably discontinued the twin 80mm fans because everyone else was shifting to 120mm fans, not due to a few returns from paranoid owners.
They would have had hundreds of thousands of returns due to FU caps

late edit: I just though that emoticon was funny and was how I felt, no offence and I didn't know it was for noob

Re: antec sp 450

antec =
bad caps
bad soldering,
bad fans
bad prices

and they did sell a 120mm fan version at the same time as yours,
they were aimed at different customers.

Re: antec sp 450

Be sure to replace the 22uF/50v cap down near the mains/fuse.

Re: antec sp 450

I just picked up an Antec SmarPower 450 (SP-450) from the flea market today for $10.

Can you give me tips which caps (series) to replace the Fujjyu/Teapo combo with? Did you guys replace the primaries, and if so, with what?

Re: antec sp 450

Be sure to replace the 22uF/50v cap down near the mains/fuse.

I just got a dead Antec SP-450.

I haven't take the entire thing apart yet, but at first glance, surprisingly, I can only spot one bad cap (circled in red). The Fuhjyyu caps on the secondary side all look flat!!! I know you can't see much with the heatsinks in the way.

With my multimeter, the only voltage I get is standby (purple) at 4.98V DC. I tried shorting out green and black with a paper clip, but nothing turns on. Any hints on where to start looking for the other voltages?

Obviously, I will recap everything once I determine the problem.

PS. Do you desolder all the white/green/black wires from the AC plug and on/off switch to access the underside?

Re: antec sp 450

Both of those caps are for the 5vsb. Get them replaced and move forward.

I can't believe I didn't see/remember that thread. I searched for antec 450 and not sp-450. Thanks for the pointer.

It might take a few days for me to work on this due to disappearing sunlight which is required for me to see what I'm soldering.
