ee spx-250w of doom!

[ratdude747]

the world's worst atx psu!

i will have pics soon

what i know now:

its an ee spx-250w.

its light and crappy

its got a few small ruLycons! jee and sc too. very bloated!

thin metal/wire, tiny heatsinks, no filter, poor vents.

4 diodes, all 2a

tiny transformers

bad looking fan

tiny 330uf 200v primary caps

i will have pics in 'bout an hour or 2 (i have yet to take/resize them)

you can already see its going to be a nightmare... get ready for fail!

Re: ee spx-250w of doom!

ok, so camera flash gordon here horrifically misjudged time: i now have the pics

WARNING- if you have a weak stomach, grab a barf bag NOW!

first: the label:



250w my ass. 25.0 on at most. you will see why... READ ON!

next, an overview:



pitiful in every way. not a single good brand cap, even some fakes! say hi to rulycon!

the primary side (or lack thereof):



nothing good here:

• tiny jee primaries
• 4 2A diodes
• no choke
• no x caps
• no y caps
• lots of jumper wire

next, the weak secondary side:



lets see... i DID see 2 PI coils, but only one torroid... few caps, and they are sc if bigger, rulycon if smaller w/ "K" vent. most vented caps are bulged. thin wire too.

next, the heatsinks:



look how small they are! tiny silicon too, and look at those winpy transformers! 250w is soooo overrated for this box o' fun

last, the sheet metal:



those are the only vents in this unit, other half was solid. they were clogged with dust when i pulled it form a bp6 box...

and trust me, the metal is thin. really thin.



who buys this crap? lesson: a cheap psu is usually going to cost you more in the end.

Re: ee spx-250w of doom!

There's another brand I know of called "TT" (NOT short for thermaltake). The heatsinks are fairly small, the fans sometimes only last a few months, I havent seen them with good caps, and the case is so thin that it gets bent when you plug in and unplug the power cord, although the ventilation is a bit better than yours

Looks like a classic leadman.

Re: ee spx-250w of doom!

i think its a pre-hisoric powmax here's why:

ee also makes cases. i have 2 right now, the one this one came out of was well built, i have a brand new ee that i flimsy with a new psu that i have yet to open... and the both have ee stamped in big letters in the bottom.

BUT- i used to have a powmax case... the bio II to be exact. flimsy but looked sweet. and it had the same logo in the base.

anyway, i have a fex old pics of it, and this is the only one with a hint of my find:



i had thought it was CE as in the safety certification, not ee as in a brand. i was wrong... i rember it being stamped the exact same way os the oler ones i have.


so, powmax=ee

Re: ee spx-250w of doom!

My guess would go with Leadman/Powmax/Sun Pro as well. The "7700"-marked transformer and those tiny heatsinks seem to be consistent in their low end power supplies. Looks somewhat identical to a "380" watt Sun Pro Raidmax of mine.

Speaking of the crappy heatsinks, look at the heat damage on the PCB in the second to last pic !
And, yes, it is possible that this is a really old Leadman unit, judging by the cut-out for an old style AT turn-on switch. I've noticed that old Deer PSUs have this as well. They probably just used the same case production line for both AT and ATX PSUs. Apparently a cost-cutting technique saving valuable beans.

i have seen an old agi (re-badged hipro) with that. saves cash, and to me, is no problem.

Re: ee spx-250w of doom!

Looks like a real antique - probably from mid 1990's. Antique value means it is worth more than a recently blown up psu. So its money value must be going up!

Does it work?

Re: ee spx-250w of doom!

i still see those cases.seems to be a way to fake a ce stamp in the buyers mind without being certified by ce.
some are so cheap they dont even deburr the steel after stamping.
we call them "ginsu cases"

[ratdude747]

Re: ee spx-250w of doom!

never tried using it... i knew it was bad and didn't want to risk it... not worth fixing in my book.

Re: ee spx-250w of doom!

NO kidding. haha

Re: ee spx-250w of doom!

"ginsu cases" Yikes. DEADLY cases. I had gone through these and got *nasty* cut that bled like crazy from these. That made me go for good cases with rolled edges from on now nearly decade and half ago.
