Elecool (LC-Power) LW-7250 Plus

[UraBahn]

Hello,

Last night when I was at my brother's, I picked up an old Gateway 2000 P5-166 that someone put in a newish-looking case before placing the system (and the 256MB of CL2 PC100 SDRAM and Philips CD-burner inside of it) out by the dumpster. Being the environmentally-conscious (read: cheap) computer guy I am, I took this thing home and, upon opening it up, found it uses an Elecool (rebranded LC Power) LW-7250 Plus '300w' power supply.

Unit looks reasonably well built (but still no Delta or Hipro by any means), had no missing critical parts, some rather dorky-looking 'copperized' heatsinks (which I am 100% sure aren't copper), below-average quality-ish Ruilian Science .22a 80mm fan, and a garden variety of terrible-quality caps from HEC, B.H. (Bor-Hourng or something like that), Decon ('kills power supplies dead!') and UNITED (*not* United Chemi-Con, this looks like a knockoff). Oddly enough none of those lousy things look bad, but I still wouldn't trust any of them. I am running low on caps so I just replaced a few of them for now:

680uf 200v HEC --> 680uf 200v Matsushita UP
1000uf 16v B.H. --> 1200uf 16v Nippon Chemi-Con LXF
2200uf 10v B.H. --> 3300uf 10v Nippon Chemi-Con LXJ (GND rails)
2200uf 10v B.H. --> 2200uf 6.3v Nippon Chemi-Con LXJ (5v rail)

Unfortunately most of these caps are 10mm, and the insides are really cramped so none of my 12mm Nichicon PLs will fit.

Unit worked fine when I powered it up after the mini-recap. (Course, all it's got running on it ATM is that P166 I mentioned earlier.) I take it LC Power isn't the same as L&C? This unit looks way too well-built to be L&C. I'll put up some pictures of this beast soon when I get my P3 server up again.

I take it LC Power isn't the same as L&C?

I was exploring that very question today at Hardforums... from what I can tell, LC looks to be using Shenzen Chi Yuan as an OEM. Evergreen uses them too.

They do look reasonably well built - not the best, but not the worst. Definitely not L&C/Deer.

I have issued this in the PSU section too, as there are some LC-Power models out there, wich are not that bad built. I ended at Shenzen Chi Yuan too by the UL number search.
Particular model was an LC-6550. I think thy are fine for abouth 350w to 400w at mediocre efficiency. But they have now a more efficient model availiable.

Well my server needed this power supply, so unfortunately I won't be able to get any pics of it at the moment. I think Gonzo posted some pics of a similar LC power model. If I remember correctly mine looked alot like his.

So far everything looks okay, it's powering my Jetway 993AN Slot-1/Socket-370 motherboard, 550 MHz 'Katmai' Pentium III processor, 256MB of SDRAM, an ATI All-In-Wonder Pro video card and two HDs: a 5GB Maxtor Galaxy V and a 13GB Quantum Fireball CX. Funny thing is, with an old AST VGA monitor I don't see any more of that bloody 'interference' with the screen. (I was using my flat panel monitor on it earlier, with that I saw the interference.)
