At least they actually have a little better input filter.

Still much better than the cheifmax or Real PC power or whatever reviewed on JG's bargain basement roundup.

Wow, 2007 and it still has 30A of 5v.

Same junk, different day.

I was really hoping Leadman/Powmax was out of business for good.

"safty", "no servicing components inside", "safe quality", "tested comply with FCC standards"
Engrish anyone?

Lovely capacitor choices too. And look at the 5vsb transistor on the second picture - it's tiny!

But at least you have 2 fans for an odd project on a rainy day. The input coils and input capacitors don't look too bad either. Fans seem to be temperature controlled as well (green thermistor on 2nd and 3rd pictures). This PSU might actually be okay for a PII/P3-class PC (only if it had good capacitors though, and if the main transformer is not of the smaller type).

OMG!

LOL! "Safety" and "Powmax" on the same sticker!

It's an "All-NEW Safety Power Supply"?

This is obviously a new definition of the word safety involving the survival of the fittest. (as in: kill off the stupid and everyone else is safer)




Better kill it before it multiplies,
Keri

PS. Well, it does look safer than the brand new "old" Powmax that's lurking under my futon only because it's not heavy enough to use as a doorstop.

What a power supply that is too light to be a doorstop!

powmax's name is backwards- it should say "maxpow"

which means MAXimum POW from use (when bad caps go POW and explode)



another more correct name: P.O.S.max

love the thin, s***ty wire too

Thin shitty wire is a understatement.

Those things would either get really hot or just burn if the psu actually put it's "rated" specs on them.

... and the hd would click as it kept restarting due to lack of power... using too thin of a usb cable does that to external hds

are light keyboards bad too? found a viewsonic one at goodwill with a thinner than usual usb cord. thin form factor as well, lots of shortcut keys that all work with ubuntu . euro sign on 5. thopugt it would be good for travel with the thin, easy to bundle cable and thin ff/lightweight. i paid $5

good or bad deal?

It depends - light keyboards are better for moving around, placing on the lap, etc. However, among the better basic USB keyboards I've found is an Acer KU-0355. Medium weight, acceptable key-press feel, durable, never hangs. Downside is that there's no palmrest or integrated USB hub - it's just a basic surplus plug-and-forget workhorse keyboard.

mine is a viewsonic ku-206. has standard us keys plus:

2 windows/super keys

euro on 5

shoertcut keys: home, mail, forward*, back*, search, refresh, favorites (also kinda looks like camera so i use it for screenshot), stop*, mute, volume up, volume down, stop^, forward^, play (pause), back^


^=playback

*=browsing
i have 5 keyboard that haver hubs- a dell perfomance usb, apple usb, apple pro usb, hp pavillion win me usb, microsoft natural pro usb and ps/2 (built in y-cable)

all but the mac ones are in use, the macs have the best feel but are thick and heavy- good for desk, bad for travel. this one has decent feel and is light as a feather/ 1" thin (keys included, see viewsonic's spec page). thinner cable so my velcro wrap works better.

It's "safty", not *safety* so technically this doesn't mean the PSU has to be safe. They removed the "e" for legall purposes .

Fuse should be under the white wire in the last picture.
I know because I have a LP6100-D, though mine was built much better. Surprisingly it lasted for 5 years before the secondary-side caps died, then it just became unstable.
In terms of Powmax quality, I think this is one of their better designed PSUs. It's for heavy 5v use however, and a modern 12v-based system will burn it up quickly.
I used mine on a socket 462 Duron Applebred system where 12v draw was fairly low, and even there the 12v line was at 11.89v most of the time. 5v and 3.3v were good though.

I'm guilty of using a LP6100-? for maybe 4-5 years in the late P3 days. It was pushing an Athlon 750Mhz [slot type] for about 3 years of that. Had no PSU problems at all. [That I knew of.]. That was back before I heard of the whole caps issue and I never looked inside it back then. I came across it in a junk box out in the store room a while back so I opened it up for a look-see.
- Yup, I found bloaters. Only 2 or 3 though.

With what I know now I'm wondering if that's what caused the HDD problem that inspired me to replace the system.
At the time I blamed it on the fact that I had just moved and the PC got to ride in the trailer.
The drive showed up corrupted and the OS wouldn't access it at all.
I moved it to a new system and started using some data recovery software [Easy Recovery Pro] on it to get my files back.
Then after a reboot in that other system suddenly the drive wasn't corrupt any more.
I put it back in the original system, all the files were back, and it was working like nothing ever happened.
The drive never glitched again.
- Strange..

I got everything back but I didn't exactly have a warm fuzzy over what happened so I built a new system and retired that one.

Probably a good thing because that motherboard [still around too] is loaded with Tayeh caps.
None 'look' bad, but they are Tayeh so that doesn't mean much.

Back before I knew about psu's built quality, and capacitor issues, I had a compaq presario something-or-other that had a 800mhz athlon slot a with 256mb ram and a VIA chipset.

I dug it up not to long ago to see what caps it had and if it was worth using as a server or folding box or something, but it had teapo and taicon caps all over. None were bloated, they looked ok.

Long story short it still works wonderfully somehow, no stability problems what-so-ever. When I first got it about 2 years ago, I recall taking out the delta 250W psu (thinking it was crap) and putting in a solytech rosewill 350w.

why?
i would say this is the worst sort of the psu one can bump onto; it seems it has that 5vstby circuit that kills mobos(no ic).

jguru's basement roundup is a bit misleading: it's more important if psu can kill mobo than if it will destroy ITSELF if it's overloaded, primarilyl because it won't be overloaded, because no user will buy load tester just to blow psus, like jonny did.
