Re: thermaltake tr2 430w

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.

I don't agree.

Re: thermaltake tr2 430w

What???????

Btw the photo you posted shows the 5vsb line.

Are you sure you know what you are doing?

not as well as you guys know but enouth to recap it.\
the second set of pictures has the 12v.

Well, Th3_uN1Qu3 has pulled 500W from a 35 size transformer before. And this review shows 470uF Capxon primaries (220V/105C) doing 350W with 76% efficiency at 115V (at 50C room temperature, too):

So it is possible.

EDIT: I wouldn't want to risk it. But I have 300W Hipros with only 470uF primaries and they do 300W alright at 75% efficiency and continuously. Efficiency won't be fantastic but it can work.

It's 10% possible or less. Would you risk blowing the psu and/or damaging the hardware connected? I wouldn't.

Ok, no prob! Either way I would replace the 1000uF caps with 2200uF or 3300uF.

I would also replace the 5vsb 470uF capacitor with 1000uF.

If momaka saw this, I am sure he would warn you about that resistor near the 5vsb capacitor. Try to bend the resistor away of the capacitor if you don't want it to cook the cap.


12V has actually only 1 cap and no coil. You might want to replace that 2200uF 16V cap with a 3300uF 16V cap.

Please post a nice picture of the solder side if it is possible.

Do you mean that you think 470uF primaries can't do 300W continuously or do you mean 350W? Or do you mean 560uF primaries can't do 350W continuously?

And, alternatively, maybe you could bend (slightly) the capacitor away from the resistor.

Re: thermaltake tr2 430w

i marked the corner that is 12v had to open up the psu again i had just put it back in my computer.

Indeed, I do both!

i just replace one of the 470uf or all 3?

[Phaihn]

Re: thermaltake tr2 430w

i just replace one of the 470uf or all 3?

also for the 3300uF do i go up to 16v? or jus 6.3 and 10?

Re: thermaltake tr2 430w

I attached a pic with my suggestions. The cap circled is 85 Celsius cap. This is unacceptable for a power supply. You should replace it with 105C cap. I am not sure if this cap is for -12V or 5vsb. If it is responsible for 5vsb filtering along with the other 470uF I would advise you to put a 1000uF there too.

also for the 3300uF do i go up to 16v? or jus 6.3 and 10?

You better stick to the original voltage values. 6.3V can be replaced with 6.3V or higher Volts (10V, 16V).

10V -> 10V or 16V

16V ->16V

Re: thermaltake tr2 430w

alright thanks a lot i dont know if ill be able to get this done anytime soon i put $25 on preload credit card the other day and i just found out tody they took $15 for a monthly fee i was really angry about it.

Re: thermaltake tr2 430w

i am going to catalog the caps i have and see if i have the caps i need in my collection.

Re: thermaltake tr2 430w

The rule I use is 1uF/watt and is common in SMPS design (without PFC front ends.) Remember with two 470uF 200V in series, that's just 235uF... you're getting serious ripple on the primary, so the transistors have to pump more current through the transformer and the transformer needs a greater turns ratio.

It's much cheaper to use bigger caps and smaller transformer/transistors to get a higher output power, than a smaller cap and bigger transformer/transistors, so in general when I see small caps, I think small output power.

are you saying i should use bigger primary caps?

Does that apply for the secondary too (hugely powerful rectifiers vs. smaller output capacitors vs. coils)? As in, it's much more prudent to have smaller rectifiers and bigger capacitors (in capacitance)/more coils on the secondary side in terms of filtering than largely powerful rectifiers and smaller capacitors (in capacitance)/less coils?

No, it's far too variable with secondary design to be useful for that. It's just a basic approximation for non-PFC power supplies. Good designs use 1.5~2uF/watt. Antec used two 1200uF 200V in series (600uF) for a 350W power supply. Not saying Antec are any good, but at least the output power is probably honestly rated.

In general at high frequencies capacitance is less important: it's ESR which is the killer. Basically you want to dump all that high frequency to ground and get flat DC out. Lower ESR, less impedance for the AC. That's a basic view of the problem. I'm sure th3_un1qu3 will improve on it .

[Wester547]

Re: thermaltake tr2 430w

So then... having low ESR/impedance/high ripple rating capacitors on the secondary guarantees stabler power and matters far more than having the highest uF rating?

And I always thought Antec rebranded PSUs, so whether their PSUs were good or not would depend upon who they're branding (whether it be Seasonic, Delta, FSP, etc...).
