Current EA-650 Green

Older EA-650 Greens

🤣 This is funny, look at what just happened here:

If you watch at the two pics carefully, the top one from Amazon sports ' 0-761345-27508-8 '.

Google that and you'll find it's the model number for the EA-550. 😀

Someone at Amazon just photoshopped a '6' on a picture of a 550 to illustrate the 650 😵 ... throwing us into confusion in the process. 🤣

Isn't it easier (and cheaper) to buy some Zippy/Delta server-grade ATX PSUs? I've bought a couple of HP-6500p and 6400p that can withstand any +5/+3.3V load. Considering the high-grade componentes they've used I doubt you will even need to recap it.

I like it, as long as the fan doesn't make enough noise to collapse your house.

Guys I hope this topic goes well for my question... I own an HP Pavilion socket 939-based, currently in use as XP mule in my garage, its PSU yesterday suddenly stopped working after having powered up the electric current via power strip: the PC has not more initiated, the strange thing is that the characteristic blue LED light on the power button started flashing continuously. I tested the power supply with the same PC by unplugging all boards and devices: same situation. I had to replace the power supply with another one, however Pavilion original PSU seems pretty good as construction, and above all: it's quiet. I'll post some pictures of the PSU, I do not see inside defective or swollen capacitors: what could be the problem? It is worth adjusting this PSU? What do you think?

IMHO one can't get anything much more long-term reliable than a server-grade Delta-made PSU with jap caps inside.

Probably one or more caps inside are KIA or dying and their ESR is too high (all swollen caps are bad, but not all bad caps are swollen).

ESR tends to drop as caps warm up, PSUs/mobos that wouldn't start due to bad caps's high ESR when cold can sometimes still boot (for a time) if heating up brings down ESR low enough:

HP comp PSU with blinking LED starts after being heated up with hair dryer, episode 1

HP comp PSU with blinking LED starts after being heated up with hair dryer, episode 2

^ That's a dead giveaway of bad caps with too high ESR.

Here are some pics on that JUSTPC (USA) Inc 450watt 20pin supply. Specs according to the sticker are: 450watt max output. 20A on the 12v, 40A on the 5v, 28A on the 3.3v, 0.5A on the -5v, 0.8A on the -12v and 2.0A on the +5v/SB need any closeups of any parts let me know! Sorry for the crappy pics but my camera sucks and the lighting in my house is terrible. I will try to snap some better ones later.

I just had this happen with a 250watt Bestec out of a lga775 HP Pavillion. It ended up having 3 or 4 bulged out bad caps. I bet they are indeed bad caps at fault, even if they are not bulging. Bestec seemed to have regularly used poor quality caps (Teapo's, Crapxon and Jamicon) from the 4 or 5 I have used/seen. If you have a spare PSU I would go ahead and just swap it out and toss the Bestec.

What's funnier is that the same photoshopped photo is used on Antec's website so Antec did the photoshopping and distributed it.
http://store.antec.com/earthwatts-green/ea-650-green.html

Antec has always been a slimy company.
They used to hire people to troll forums to promote their products.
I ran into one that called himself AntecRep on experts-exchange.com and on badcaps.net and a few other misc places.
This was when Antec was heavily into using Fujhyyu caps in their flagship models and at badcaps.net (were most people know electronics) it more or less resulted in a pile-on (the whole community on the AntecRep). He didn't last long anywhere that had people that really know PSUs.

My experience with Delta and Zippy has been generally very good.
The Zippy/Emacs in particular like to use a lot of Chemicon caps.
Not all models are created equal though so the best plan is to take a peak inside to be sure.
Even with a few crap caps server grade models usually last longer than consumer models.

gdjacobs is right. Some of them are pretty loud.

Looks cheap & weak (apart flom blurry 🤣 ). Little input filtering, dwarf bulk caps, slim heatsinks, small main transformer, no mag-amp for +3.3V. I wouldn't push that thing above 250W.

Thanks! That is what I figured. Oddly enough they spent the extra pennies on sleeving the cables and putting two good quality 80mm fans in it along with Rubycon primary and secondaries. I think I will use it in a P3 or slow P4.

Funny thing is that the 500W is quieter than the 400W (which is very cramped inside - when I opened one of mine to take a peek I couldn't identify anything 😵 )

Unfortunately, they're the only retail PSU vendor that has a manufacturing contract with Delta anymore, so if you want absolute top flight construction, Antec (on select models) is it.

The Bestec 250w models had a reputation for blowing out and taking the motherboard's chipset with them.
Problem was seen in a lot of OEMs. Emachines, Gateway and HP included.
https://www.google.com/#q=emachines+bestec+po … +supply+failure
I have avoided them since that time.

That doesn't mean your 300w Bestec is hopeless, I just personally wouldn't bother with one.
Over at badcaps.net Bestecs have somewhat of a following. Amazingly actual fans.

And a repair of one.

everell (at BCN) would be one to talk to.
I think he could probably draw out a Bestec schematic from memory.

Yes, but I've seen no evidence yet that this new version of Earthwatts is made by Delta.
.

THE NEW PHONEBOOK IS HERE!!! - THE NEW PHONEBOOK IS HERE!!!

No, actually just the Enermax EG465P-VE I mentioned earlier is actually here now.
Actually testing and reworking it will come later but I took a quick peek under the hood.

Looks like a good solid PSU that would be reliable with fresh caps.
As expected it will need recapped but none are actually bad yet.
No hard to find sizes of caps.
The fans are both ball-bearing type.
Soldering looks good.
And the big plus: It uses connectors so you don't have to desolder anything to remove the PCB to work on it.

Looks like a great "recapper" PSU for +5v heavy apps and very easy one to reacap.
These might not even need recapped immediately. Well cooled so caps last longer.
This one is an Enermax EG465P-VE but there is also a EG365P-VE that should be about the same.
At the moment these appear to be easy to find and not too expensive.
- Remember to READ the labels.
- The same model numbers are used for different ATX specs and their ratings are different.

Details of the caps.
The primaries are the horror of Fujhyyu but they are large (heat dissipation) 22x50mm and 1000uF 200v.
Primaries hardly ever blow so I'm not too worried about those despite they are Fujhyyu.
- I didn't not do any circuit tracing. The following are guesses by location.
All the rest (I can see) are JPCE and none are bloated, presumably because of the cooling.
[JPCE is aka PCE by some people, made by CEC-Coils. Common in older PSUs. They are a so-so brand.]
The main OP filter caps:
The 12v has a single 12.5mm 3300uF 16v JPCE-TUR
The 3.3v and 5v each have (1) 4700uF (12.5mm) and (1) 2200uF (10mm) JPCE-TUL
The +5vsb has a pair and the -5v & -12v one each 8mm JPCE-TUR
None of these will be hard to find replacements for.

I suspect it isn't, but it's no more than a gut feeling. Be nice to know for sure.

Actually, it would be nice if there was a table or database for tracking this sort of information. Unfortunately, everyone is guilty at one time or another of substituting a decent quality power supply for something sourced from the Dodgy Brothers, and I like the idea of being able to use the data as an instrument of punishment.

Actually at second look the secondaries are all fuhjyyu's. Time to burn it with fire! Need to stock up on some good supplies, iv sold or given away all my good quality ones it looks like. Other spare "500" watt has no brand name and every single cap is a fuhjyyu. Also Im 99% sure that it has one of those cement PFC's since it weighs a ton and has tiny heatsinks.
