thermaltake tr2 430w

[Phaihn]

i am thinking about recapping my thermaltake tr2 430w while i am working on the monitor killing 2 birds with one stone so to speak i was woundering if anyone knows if all these have the same caps in them or are some different and does anyone know what caps are in it just dont feel like opening it up tonight i will crack it open tommorow. as a side note ive recapped it before with spares ive had in my collection so i am just wanting to replace those with good Rubycons.

680uf 200v x2
470uf 6v x3
1000uf 6.3v x1
1000uf 10v x2
2200uf 16v x1
2200uf 6.3v x3
10uf 50v x3
22uf 25v
4.7uf 50v
1uf 50v

some of the smaller ones are pretty hard to see

Re: thermaltake tr2 430w

anyone have any advice on what to get if i want to increase wattage of the psu above 350w?

It's a HEC OEM design... a review is here: http://www.hardwaresecrets.com/article/332

Not much you can do about increasing over 350 watts, in the review the 12v ripple was already at 85 mV at 16A load on 12v
Might get it a bit smaller by using a 3300uF 16v capacitor instead of the 2200uF 16v capacitor.

Other than that, like i said, not much you can do. It's an old design optimized for 5v which was tuned to up the 12v that's needed for new systems.

15-16A on 12v is still reasonable, enough for using it in a system with a video card that doesn't require a pci express connector, or even a card with a single 6pin pci express connector, that you know it won't use more than 80-100 watts when playing games.

That would leave 80-100 watts for the processor and fans, which is enough for single and dual core processors, even some quad core processors.

ive read that.. figured as much i might not be able get much past 350w.

Re: thermaltake tr2 430w

should i bother changing out the smaller caps or just leave them?

You can leave Teapo and OST, they are not so bad in well cooled psus.

The primary caps are only good enough for 350W max. For 400W+ it should have 820uF.

Check if the 12V line of the power supply uses only 1 cap. If 1 of the 470uF caps is used for 12V you need to replace that cap with 1000uF or 2200uF.

Judging from the photos you posted it seems that 5v and 3.3V each use 1x1000uF and 1x2200uF. Another possibility is that 1 of them uses 2x2200uF and the other 2x1000uF. Either way I would at least replace the 1000uF caps with 2200uF.

5v

With good enough silicon, even 470uF/560uF primaries can do 350W, though of course we'd be talking about more heat output + 7x% efficiency. I think it depends heavily on the rest of the components, similar to how a 35 size transformer can do 500W with good enough components. It also looks like there's conductive glue near the 5VSB output; I'd recommend getting rid of it.

the yellow glue or white?

[Wester547]

Re: thermaltake tr2 430w

It's less yellow (if I'm not mistaken) and more tan. Tan glue with added heat and age becomes brown (it darkens) and can become conductive over time, so I recommend removing it.

ok

Re: thermaltake tr2 430w

some of that glue is in the middle of alot of sensitive parts i dont want to damage anything.

Re: thermaltake tr2 430w

You don't -have- to remove it but I hope the PSU is cooled well enough for it not to cause issue.

[Phaihn]

Re: thermaltake tr2 430w

well think i got rid of most of it
i reversed he fans i hope hat improves cooling.

[Wester547]

Re: thermaltake tr2 430w

Reversed the fans? I thought a PSU was only meant to have the fan blow air one way (effectively out). I'd suggest keeping it where it was by default unless the PSU by default blows air into the computer and PSU (unless you mean case fans).

[Phaihn]

Re: thermaltake tr2 430w

i figured it would help if the psu fans were sucking cool air in.

[Wester547]

Re: thermaltake tr2 430w

The problem with that though is that at that point the PSU would be blowing the hot air from the system and PSU back in. It should be the other way around (blowing hot air out).

What???????

Btw the photo you posted shows the 5vsb line.

Are you sure you know what you are doing?

Re: thermaltake tr2 430w

i just put them back the way they were
