Re: PSU advice requested

bad link again..what the hell is

http://cgi.ebay.com/ws/eBayISAPI.dl...em=170406362584

it'll take you at least 3 tries to link properly....

and then, buying fans on ebay? is there really no decent store with decent fans in whole of usa?

Link doesn't work PCBONEZ...

"Page Not Responding"

Something whacked. Try this:

Remove fan.
Install this to PSU but out back of the case.

.

That would be interesting to see on the back of a case.

Re: PSU advice requested

Nah, it's too drastic. My buddy needs a PSU, so I'll be selling him my AcBel for $15 (he doesn't care about the noise) and buying both the 400w Delta and the 400w HiPro. Whichever one I like best will go in my system, the other will go in the downstairs HP to replace the 7 year old Bestec in it.

Re: PSU advice requested

Bought the Delta PSU (along with a couple goodies), will keep you guys updated on what effect it has on how loud my system is.

Thanks for the link patch Toasty.

Drastic? - Me? - nahhhhhhhh.

Though it's a good idea. Would really only work if you have a newer case with the completely open area for the psu, most of the old cheaper ones out line the fan and the plug covering up the fan's screws.

Not very handy with tools are we?
It's called 'trimming'.

Re: PSU advice requested

New PSU (the Delta 400w that 370 linked to) comes in Friday.

I might do a full recap later on and banish those Ltecs and CrapXons, but for now I will just be happy to have a quiet PC. I'm also kinda discouraged by johnnyguru's article where he recapped a CWT-built Antec and the ripple actually went UP.

Re: PSU advice requested

Well, thats not going to be the case with all power supplies. Just make sure ESR matches or exceeds as well as ripple current. Maybe move up a bit in uf.

>I'm also kinda discouraged by johnnyguru's article where he recapped a CWT-built Antec and the ripple actually went UP.

if you're afraid of that, find replacements that are EXACTLY the same(esp. the esr), without the "or exceeds" portion.
but there is a "settling-in" factor that that article didn't take into account, ie they didn't wait for those caps to settle in there...
so that article is not really a law of physics or alike...heh

i just ordered fortron that probaby has capxon, any you know what?
i won't be touching it while it works ok.
if/when problems occur i'll do something about it.

Re: PSU advice requested

i4004, you're assuming the junk caps were rated correctly at the factory. My guess would be that they were not.

If you're going to do that, you need to measure the actual capacitance, and ESR, of the caps out of the unit, when new, and match that.

exactly.
i didn't really say one should trust mfrs numbers.

time to settle-in aside, that's another error of that test at jonnyguru; there was no test of old vs. new.
it really would be interesting to see esr and capacitance numbers for old and new, AND THEN esr and capacitance after few tens of hrs of work(for new caps).

i've found a convenient way to measure capacitance (with analog meter on ohm range...it's a matter of comparing readings of few good ones and then writing down the deflection it reaches) and i'll measure some crap caps in this respect, but i think i'll find stuff we already know: if esr is ok, capacitance should be too....if not, capacitance will probably also suffer...
ie blown cap probably has decreased capacity.

also, given that capacitance tolerance is usually 20-30% one doesn't need to be ultra precise....

I just mentioned that article in my last comment.

Re: PSU advice requested

The new Delta came in a day early (props to FedEx).

It's.... so.... QUIET!!!! The AcBel was definitely the sole noisemaker in my PC.

And now, to fix the "2-seconds-to-black" Dell E172FPb I found for free on Craigslist....
