Hi,
I was surprised to see that the brand Rasurbo hasn't been mentioned even once on this forum.
Well, in May 2009, I was dumb enough to buy two Rasurbo Basic & Power RBP-450CL units (for 22 EUR each). It seems they were manufactured already in 2006.
As it turns out, I didn't need these Rasurbos until about half a year ago, when a couple of my old PSUs died. Now, after only a few months of relatively light use, it has become troublesome to get the Rasurbos up and running; one might have to press the computer's power button about a dozen times until the Rasurbos finally agree to keep running (I'm sure the hard disks really appreciate this), instead of powering off after only a second or two ...
Once you get the computers up and running, there usually won't be any stability issues nor any other apparent problems for days. Isn't that a bit surprising?
I've now taken a closer look at one of the Rasurbos and found six quite obviously damaged green 1000uF 6.3V Teapo caps. The one right next to the large 15 Ohm resistor near the purple 5VSB wire has almost turned black, presumably because of excessive heat (the PCB looks a bit burned there, too).
Please take a look at the attached pictures. Is this a very badly and cheaply designed PSU?
Cap brands, capacitances and voltage ratings:
- C34, C33, C25, C28, C26, C27: Teapo 1000uF 6.3V (green).
- C20, C21: CapXon 470uF 200V (dark purple).
- C12: Su'scon 1uF 50V (black).
- C14, C48: Teapo 4.7uF 50V (brown).
- C31, C39: Teapo 10uF 50V (brown).
- C41: Teapo 22uF 25V (brown).
- C22: Teapo 470uF 16V (brown).
- C23: Teapo 1000uF 16V (black).
All caps except the six green Teapos appear to be in good condition, but I guess you never know, with brands like Teapo, Su'scon and CapXon ...
Would you expect this PSU to work like new after a recap job or could there be other problems as well? Why is the above mentioned resistor getting so hot?
If I decide to recap this unit, should I replace *all* caps? It's not too likely that the caps with capacitance 22uF or below are ever going to fail, is it...?
I have already successfully recapped three motherboards (QDI WinneX 3, Asus K8N-E, Epox EP-8KDA3J), so this PSU would obviously be a quick and easy job.
I did a bit of googling and it seems some of the newer Rasurbo PSUs have been getting some pretty good reviews. Hopefully the reviewers know what they're talking about...
