Re: Help me find a replacement power supply!

Not to sound like a grouch, but a 1st gen Phenom X4 in a small case like that is not a good idea at all. It's going to run very very hot and likely neither the motherboard nor the video card will...

Re: Corsair HX 450W shuts itself down after a while

Probably silly to ask this, as I'm sure you've checked, but does the PSU fan run when the PSU is upside down? If yes, does the fan appear to spin freely regardless of which orientation you have the...

Re: Corsair GS800 fan spinning only on boot

This might be a silly question, but can the fan actually spin freely?
In other words, if you spin it by hand, does it take a while to come to a stop (and do a little "wobble" when it finally stops)?...

Re: Suitable replacement for shorted rectifier

For an old-ass PSU like that with a rather weak 12V rail, it probably really isn't that important what rectifier you get on the 12V rail.

Though if you really wanted something closer to the...

Re: Denon AVR-X2000 mainboard caps bulging

Was the bad Carli X2 cap placed across the incoming AC power lines for the 5VSB supply?

If yes, I suspect the amp might have seen a power surge on the line while it was on. Since the large Elna...

Re: Task TK-940TX-DF Blowing fuse

That's an interesting result.

It suggests the PSU might just be OK, but just not liking the still relatively high impedance of the bulbs on the input. However, I haven't seen a PSU that doesn't...

Re: D-Link router - faulty power brick?

Yup, that's why I left the 10V, 1000 uF Chemicon KZE in there. I also had 6.3V, 1000 uF KY available at the time, and even these have better specs than the Teapo SC caps original to the SMPS. Not...

Re: Original Xbox Replacement Caps

Nichicon had a manufacturing flaw/problem between 2001 and 2004 with the HM, HN, and HZ series. In 2005, they got most of that squared away - at least with the 16V and higher voltage -rated caps....

Re: Original Xbox Replacement Caps

Yeah, MBZ is pretty stable.

MCZ and MFZ, on the other hand, can be a bit more unstable - usually when placed in hot spots. But those two are newer series, so you won't see them on the original...

Re: D-Link router - faulty power brick?

TO-220 resistor?
From what I remember, and the pictures I've attached previously, there are only two TO-220 devices: a MOSFET on the primary side in an isolated TO-220 case and a schottky rectifier...

Re: Fisher Scientific T-30 Metal Detector - Circuit schematic

Looks like someone soldered two "modern" resistors in there at some point. I wonder why that was.

Unfortunately, I don't have much knowledge in the way of metal detector theory, but if bad comes...

Re: Kitchen range hood not turning on

Is that a picture of the power supply board after you replaced the capacitors?
If yes, it looks like the capacitors you used aren't low ESR/impedance type, which is usually necessary for switch-mode...

Re: Task TK-940TX-DF Blowing fuse

Buzzing for single-transistor forward PSUs typically means over-load condition.

However, since you have a series light bulb, it could also be a false over-load condition, as some PSUs simply don't...

Re: Original Xbox Replacement Caps

Ah... yeah.... that would be my copypasta.
Thanks for catching that! Fixed it now. ;)


In that case, likely OK to use them.

Re: Original Xbox Replacement Caps

It depends.
If the caps are in parallel, then... MAYBE :D

I say "maybe" because of ESR.

For a number of _identical_ caps in parallel, the total equivalent ESR/impedance in the circuit, Z, will...

The first one with the direct link and I think the one with the Foxlink PSU... and maybe a few others. It was a bit random.

Just to make sure, I did try viewing this thread on different PCs and...

Re: Abit BX133-RAID odd issue, bad caps?

Hmmm.

Being socket 370, the socket is surely pinned (i.e. not BGA), so I doubt contact between socket pins and mobo is bad... but do check socket solder joints on board under good light, if you...
