My partially-recapped L&C 450W PSU

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

I got an unused fire extinguisher down the hall from the room this PC is in. All the fire extinguishers in my house are unused. The status needle in all of them is in the green zone.

I got an old 60GB Seagate in this system for testing, I kept its good 80GB WD hard drive in my Vantec external HD enclosure.

I'd be okay with the Seagate HD dying out or the floppy drive, but if anything else fails I'll be like:

That Powertek 500W PSU in that review I think looks worse than my L&C, with less caps than my L&C. Those heatsinks on that Powertek 500W look like if they came from a Powmax PSU. I've never seen a Y-B200ATX -based L&C or DEER fail before, since a have a few relatives who use them and report no failures.

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

I would recommend a co2 based fire extinguisher, it wouldn`t be that a mess if you want to blow out your burning L&C PSU

wish you get along well with your Looby & Crap PSU

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

One of them are CO2, and this is just a three-month test of this L&C in my backup PC.

With good caps in it, I may be less worried of cap failure in that thing.

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

I just replaced that temporary "dynaplex" 470uf 16V general purpose capacitor with a United-Chemicon SXE series 470uf 16V capacitor from my jar of caps.

Here are the finalized results :

2 Saturn-logo brand 330uf 200V caps - replaced with 2 CapXon KM series 330uf 200V caps

2 HERMEI 1000uf 10V 10MM cap (strange with Panasonic T vent instead of honeycomb vent) - replaced with 1 Nichicon HE series 1000uf 6.3V cap (voltage decrease not affecting anything)

Two extra spots filled in with Nichicon HE series 1000uf 6.3V caps.

1 HERMEI 22uf 50V cap - replaced with 1 Nichicon PW series 47uf 63V 8MM cap

One G-LUXON and one saturn-logo brand caps (small 2.2uf 50V and 0.22uf 50V) - replaced with 2 CapXon KM series 4.7uf 50V (unnecessary recap though)

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

One G-LUXON LZ series 470uf 16V 8MM cap - replaced with United-Chemicon SXE series 470uf 16V 8MM cap

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

-------------

Overall, primary caps and all secondary caps were replaced with quality replacements.

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

Wow Newbie2... that really is now a better L&C power supply!

I hope it works really good powering that backup system of yours!

[Newbie2]

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

My L&C power supply also runs a little cooler (no more really warm air coming out of the fan) with its new caps.

In fact, I'm testing one G-LUXON I yanked out of that L&C. The Compaq case has front USB, and there is a capacitor on the seperate front USB board. I took out the Sanyo WX series 470uf 10V 8MM cap and put in the G-LUXON LZ series 470uf 16V 8MM cap. So far so good, since its only been a few days. Pics on that thing later.

Here's the pic of the G-LUXON:

yes dry powder would make quite a mess. For anyone using an L&C i would recommend a fixed Heptafluoropropane system http://www.fm-200.com/

WHY?
WTF?
hey its your machine.do you enjoy chasing problems?

[Sparky]

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

Why is there a cap on the USB board... Anyway I doubt that it really even needs to be there so I don't think it would cause any problems unless it shorted out internally. Still unsure why you'd put a crap cap in place of a good one though...

[Newbie2]

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

This is just a test of the G-LUXON cap. I still have the SANYO cap, so if the G-LUXON cap fails, the SANYO goes back in.

I believe the cap there will be lightly used, so I believe I wouldn't see a failure in a short time.

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

L&Cs don't usually catch fire when they fail - the worst that usually happens is that the +12v rectifier shorts out, and the PSU turns off and won't start again. Or the fan gets sticky, causing the primary switching transistors to overheat and break down, taking the primary bridge rectifier with them, before the fuse blows and prevents further damage.

The most dramatic pyrotechnics you will see on an L&C is the fuse blowing - pretty tame stuff, usually. There's very little danger with a re-capped and re-fanned L&C - I've not had a single failure so far, but I also change the +12v rectifier.

OTOH, Powmax is usually a different cup of tea - occassionally dies with flaming debris being ejected out of the fan outlet.

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

If you want see a really pyrotechnic (non-nuclear) electrical fire, you best bet is failing Lithium-Polymer batteries, such as those in this AT&T DSLAM:

http://www.lightreading.com/document...image_number=2

It cannot be put out with any fire extinguisher, it burns explosively like rocket fuel and throws shrapnel. You don't want to be charging the Iphone while it's in your shirt pocket.

poor alcatel. i wonder if they're gonna get sued.

How do you know the G-LUXON cap failes when it failed?

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

he'll probably test it once in a while or wait until one of his usb flash drives explodes.

Maybe G-LUXON is getting better... I haven't seen any recent failures of them on Badcaps.

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

maybe that because they can only be found with capacitance under 1000uF, which are general purpose caps... (on mobo though)

[yanz]

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

Newbie2, maybe it would be nice to know what are the ampere rating for those +5v and +12v rectifiers on the secondary side... Btw i also do recapping for many L&C PSUs but yours seems to have "cheaper" quality..
