Re: My partially-recapped L&C 450W PSU

Here are the pics.

Shot of CapXon 330uf 200V caps

Shot of Nichicon 1000uf 6.3V caps (slightly blurry)

Shot of the PSU overhead

Comparison of Panasonic cap and Hermei cap (Hermei with Panasonic T vent)

Anybody else has a HERMEI cap just like the one I have (with Panasonic T vent)?

--------------------
Correction of previous post: The 47uf 63V Nichicon cap is a PF series cap, not PW.

Re: My partially-recapped L&C 450W PSU

Aww, you're using that to power a real actual working computer?

Ok, come on all, lets start a PSU fund for Newbie2, it'd only take a buck from us each to get him a PSU that can actually deliver 150w+ without blowing up

I don't need any PSU funds, I got a PSU in my closet with the P4 +12V plug that actually looks decent on the inside to supply 250-300W (the PSU is some Best Power 500W). I got an Antec SL450 PSU in my main PC, I wonder why those Fuhjyyu caps in it still aren't failing

.

This is just a test to see if my recapped L&C can work in the long-term with its new caps. 2 months later, and if this thing still isn't dead, it's still going to be replaced by that Best Power 500W mentioned above.

BTW, my backup PC specs:

AMD Athlon XP 2200+ 1.8GHz T-Bred Socket A CPU
MSI MS-6390 Socket A motherboard from Compaq(has Rubycon and United-Chemicon caps)

Diablotek Radeon 9600XT 256MB AGP8X video card
512MB DDR266 PC2100 RAM (2x256MB)
LG DVD+RW 16X DVD burner
Seagate ST360012A 60GB ATA-100 5400RPM hard drive
1.44-inch floppy drive
Compaq Presario 6000 case

If this L&C blows this PC up, I'll be like this:

Re: My partially-recapped L&C 450W PSU

no EMI filters !!!
thin heatsink !!!
small transformer !!!
450W ???

It just looks like a 200W cheap PSU .

My 250W cheap RMB150 Holely ATX-300P4-PFC is far better than yours.

Re: My partially-recapped L&C 450W PSU

You can peel off that hot glue and replace the remaining the secondary caps. It's not like the white epoxy used by FSP and Delta - that's pretty hard to remove.

You may also want to replace the pair of 3A rectifiers on the +12v rail with a real 10A, 200V or similar TO220 rectifier.

Even if I do, I still won't be able to replace one 1000uf 16V cap near the Nichicon caps, since I don't have any suitable replacements. The rest I do.

Should I bother replacing those tiny caps (2.2uf to 4.7uf) in the future?

I don't know if the two extra caps actually did any benefit to this L&C PSU.

Are CapXon caps actually good for recaps?

**Sparky** · 08-08-2007, 07:42 AM

Re: My partially-recapped L&C 450W PSU

The two tiny caps probably aren't a big deal.

If you have a cap that is roughly the same value as that 1000uF 16V, such as a 1200uF or even 1500uF that would most likely work OK. Increasing the capacitance value a little is fine.

I don't have any 16V caps of those capacitances. Would a 6.3V cap work in this case?

Correction: I just found a Rubycon YXB series 1000uf 16V 10MM cap in my jar of caps. Will this work to replace that Hermei 1000uf 16V cap?

Re: My partially-recapped L&C 450W PSU

I just replaced the last three vunerable-to-fail caps on the secondary side of my L&C 450W PSU. The rest are just tiny caps ranging from 2.2uf to 4.7uf.

-----------------------
G-LUXON LZ series 470uf 16V 8MM cap - replaced with "dynaplex" 470uf 16V 10MM general purpose cap

(it works fine)

G-LUXON LZ series 1000uf 16V 10MM cap - replaced with Rubycon YXB series 1000uf 16V 10MM cap

Saturn-logo brand 1000uf 10V 10MM cap - replaced with Nichicon HE series 1000uf 6.3V 8MM cap

-----------------------
I also measured the voltages on the +12V and +5V rails with a digital multimeter.

+12V rail: 11.79-11.83V (the voltage has fluctuations between the two, I'd say it's okay)

+5V rail: 5.14V (rock-solid voltage here)

No, most likely not. It probably would burst that cap because the voltage is most likely more than 6.3V.

I don't see why not, should work fine

Re: My partially-recapped L&C 450W PSU

Recap the two caps on +5Vsb as well, if you haven't already. These are usually 1000uF/10 or 1000uF/6.3. They're located near the point where the purple wire from the ATX connector is soldered to the PCB.

All the other caps below 470uF can be ignored, except the 22uF/50v, which you've already replaced.

There was a 1000uf 16V G-LUXON and a 1000uf 10V HERMEI that was close to the purple wire that I already replaced with one Rubycon 1000uf 16V cap for the G-LUXON of the same values, and that 1000uf 10V HERMEI nearby was also replaced with a Nichicon 1000uf 6.3V cap.

So, this PSU is no longer partially recapped, it is now FULLY-RECAPPED!

My L&C PSU is running fine with its new caps!

If those guys at DEER Computer Co. LTD.

are reading this, I hope they get this message straight to their heads, use GOOD caps! Also improve your PSU design and use better heatsinks.

Re: My partially-recapped L&C 450W PSU

What the cheap power supply!!

I don't belive it is a real 450W PSU, i don't need to see the PCB design and other components of this power supply first.

I just see the large can caps330uF 200V, there is no quality 450W PSU to be used with 330uF 200V as input caps.

If there is a quality 450W PSU, it should be used with 680uF/820uF 200V as the large input caps at least, it is my repair experience for the power supply.

**Big Pope** · 08-08-2007, 11:01 PM

Re: My partially-recapped L&C 450W PSU

More my personal additional opinion.....there is no worth to replace with good caps for some hardwares under quality and bad design.

**Newbie2** · 08-09-2007, 06:49 AM

Re: My partially-recapped L&C 450W PSU

My quality Antec SL450 I believe has 680uf primary caps, but I haven't checked it recently. Its voltages are still all rock-solid.

With that L&C, I believe it actually puts out closer to 200W. The PCB says "Y-B200ATX Ver: 3.1", and I've seen 330uf primary caps in a Bestec 100W PSU used in old HPs (1998-1999 era).

I just wanted to see if this poorly-designed L&C can put out a few more days or months of life before failing. So it's poor design and good caps. I'll see if it lives at least 2 months in this PC I'm using to test it.

Its +12V rail jumps from 11.79V up to 11.83V as I watched when I measured it with a digital multimeter on an unused 4-pin molex connector, and its +5V rail is rock-solid at 5.14V.

It seems to be doing the job of powering this PC well (no restarts, no problems, currently):

AMD Athlon XP 2200+ 1.8GHz T-Bred Socket A CPU
MSI MS-6390 Socket A motherboard from Compaq (has Rubycon and United-Chemicon caps)
Diablotek Radeon 9600XT 256MB AGP8X video card
512MB DDR266 PC2100 RAM (2x256MB)
LG DVD+RW 16X DVD burner
Seagate ST360012A 60GB ATA-100 5400RPM hard drive
1.44-inch floppy drive

i would have tossed that unit out on the loading dock and shot it up with the .40 cal
the junkers will still grab it for the metal value even with a dozen big bullet holes in it!

Are you 7x24 hours and 100% full load your system with this PSU?

This PC gets powered on in the later time of the morning (10:00AM or 11:00AM) and powered off at night (9:00PM or 10:00PM). With system usage, I use it daily now for Internet, e-mail, word documents, and other normal things to test how the PSU is doing. I use this machine to play Soldier Front sometimes. I think Soldier Front would use the most resources of this PC.

It's not running 24/7, it's running "9/7" (nine hours a day, seven days a week). It's used to do normal things any typical home user would do.

This PC that the L&C is in runs perfectly stable. No funny things happen (constant restarts, or any other weird things). This PC's cooling is one 92MM ADDA sleeve bearing fan in as an exhaust fan, and a Cooler Master Socket A heatsink/fan for the Athlon XP 2200+ in the system.

Re: My partially-recapped L&C 450W PSU

Be sure to keep a fire exstingusiher nearby the Deer PSU

And be sure that you can live without the components in your PC, most likley the very well designed PSU is outputting allot of ripple current, thus slowly killing HDD's and other stuff which do not filter the current at all
