Re: Antec EA-500D Question

The EA-650 is here. It's rev 02F.
Seal wasn't broke and it's so clean I doubt it's been used.
Took a quick look inside.
Found two date codes on caps. Both are week 17 of 2009.
Delta Xfmr of course. - Primaries are 2x Samxon 270uF 450v.
I haven't built an actual BOM yet [do that when the other one gets here] but I can see ALL the other caps are LTEC LZG, LTEC LTG, or Taicon PW. . .
. . . plus one 220uF 6.3mm 85c Taicon VR on the fan board.
I mean, it's probably okay there but when you are sourcing PW from Taicon anyway - WHY?
-
Not one Jap-Cap in the thing.
-
Except for one 470uF 25v PW all the main OP caps are LTG.
The way the wires are packed there's not gonna be much air flow back there.
Only 3300uF or above OP cap is a 3300uF 6.3v cap.
The rest are 2200uF or less and the supposed 3 12v rails are sharing two 2200uF caps.
-
Looks kinda WAY 'lite' on the OP caps uF [and ESR] overall.

Re: Antec EA-500D Question

I just bought an Antec AE500D as a replacement. Does anyone know what date Antec became aware of the capacitor plague and have they taken corrective action with new products?

There are several excellent capacitor plague photos here:

Antec doesn't care if you get crap caps. They still use them.
.
Earthwatts aren't as bad as the older models with Fuhjyyu but they do use a slew of iffy caps.
[Off the top of my head LTEC and TAICON for sure and possibly Capxon at times.]
Two units with the same model number might have completely different caps so you just have to look to see how your luck was.
- Good idea to check them periodically too.

Thanks for the update.
The parts that weren't written by one of us are probably wrong.

Re: Antec EA-500D Question

Thanks for your reply. I have another AE500-D arriving today as a spare. I think I'll open it for inspection and perhaps replace all the electrolytics as a matter of routine. Do you have any idea how many are involved and how difficult to get to them? They really pack these PSU's tightly.

You really just need to look because they aren't consistent from unit to unit. [Revisions and all that.]
I haven't heard of wide-spread failures with Earthwatts.
I would leave them alone and just check the caps every couple of months.
[Like when you -ahem- clean out the dust bunnies like everyone -ahem- does on a regular schedule.]

There was an EA-500 and an EA-500-D. One of them is a two PCB PSU but at the moment I'm having a brain fart and I don't remember which one. The two PCB version is a little strange to get apart but all-in-all neither one is exceptionally hard to work on as PSU's go.

Re: Antec EA-500D Question

Very good advise and thank you. I would hate to replace capacitors that are not part of the plague. I got a pretty good deal (79.99) at Amazon with free shipping. The same unit at the Staples chain is 99.99 + tax.

My computer case does a pretty good air filtering job but as a matter of routine, I take it (and the backup machine) outside once per year and blow it out. My neighbor once asked "does it work any better after you clean it?". This is a guy who doesn't use ATM's because he "don't trust them".

Re: Antec EA-500D Question

I have one of these with a burned out IC. IC904. Can anyone tell me the numbers off this IC so I can replace it. I would read the numbers but the IC is unreadable. It popped last night on me.

Re: Antec EA-500D Question

I'd be glad too.

That's a TNY278PN.

I still have this thing sitting around waiting for a re-cap after all these years. Maybe when I get my hacked P965 quad-core Xeon build up and running I'll get around to it.

Re: Antec EA-500D Question

I'm not sure if it's the right thread, but it is the best match I could found using google.
I have Antec Earthwatts EA-650 (model rev: 00F) with burned out IC904. I am wondering if it's the same chip mentioned above (TNY278PN), or if someone happens to have said PSU and check it for me.


Thank you!
