Re: Yet another Deer....wait,IT WORKS?!

Even for a low powered computer, those are really low rated rectifiers. Good job adding input filtering! But honestly, those little caps are so old I wouldn't trust them. They're probably dried out. I would at least replace the two for the main switchers. And if you can handle listening to the fan at full speed, that will help it out

Actually,those are the rectifiers now:

5v - SBL3045PT
12v - SBL2045PT - still works,even if it's 45v VRRM
3.3v - some 10A part from MOSPEC

Also,the caps are fine if you mean those around the 5vsb/PWM chip area.

As for the Delta fan...it's no problem. I have an AVC fan WAY louder than a Delta. In fact,a Delta is barely audible to that helicopter grade fan.

Good to know. Maybe Deer designed the main transformer so that it has lower output voltages. To compensate, that means the PWM pulses are likely longer. The trade-off with that, of course, is that the power output of the PSU will be much more limited.

In my opinion, though (stating it just one last time, I promise ), that 45V rectifier on the 12V cuts the safety margin just a tiny bit too close for my comfort. But I guess just wait till next thunderstorm comes while the PC is on. Or plug in a hammer drill in the same outlet next to the PC and give the drill some revs while the PC is benchmarking or something.

*edit*
By the way, are you sure that SBL2045PT on the 12V rail is not actually for the 3.3V rail? And the 10A MOSPEC rectifier for the 12V rail? That would seem a lot more logical to me. 10A on the 3.3V rail is only 33W max power - that's very low. Even the crappiest PSUs I've seen usually have at least a 15A part.

Nope. I carefully checked and 3.3 has a 10A rectifier and 12v has a 20A rectifier.

Re: Yet another Deer....wait,IT WORKS?!

Oh good. Those new rectifiers will help it out and increase efficiency. I guess if it works with the 45V reverse voltage rectifier on the 12V, I would leave it but I would leave the power cycles to a minimum. Just put it in a computer and let it run!

Also,the caps are fine if you mean those around the 5vsb/PWM chip area.

I was referring to C5 and C6

It already is in a PC with:

Athlon XP 2500+
ASUS A7N8X-E Deluxe
1.5GB RAM
Radeon HD3450 512MB AGP
80GB SATA HDD
no ODD(intended to be discless system except for Windows installation)

Re: Yet another Deer....wait,IT WORKS?!

^ That S16C40C ain't the original +12V rectifier, it was swapped at some time (notice it is much cleaner than the other two rectifiers). As Momaka says 40RRV for +12V rail sounds hairy, better 60 or higher.

I run a Schottky 20A 150RRV there in my Oh Deer! and it hasn't exploded yet .

You have eagle eyes. Nice catch .

Quoting what I said in the beginning :

Funny thing is I used it to bench test a Foxconn 865A01-PE-6LS w/ a 2.66GHz Celeron D Preshott. Note that I did this after I removed the 2 diodes on a bracket and replaced them with a 16A part (so the label won't lie on 12v ),added PI coils and fixed 5vSB that had a bulged cap.

Also it's been replaced by a 20A rectifier anyways.

Re: Yet another Deer....wait,IT WORKS?!

What OS?

Windows 7 Ultimate. Before anybody saying anything,I've removed most of things I don't need. (except NET Framework)

[Behemot]

Re: Yet another Deer....wait,IT WORKS?!

Try Tiny7. Or TinyXP, that's better

It's a Tiny7 clone that I use.

Why discless?

Why discless?

USB faster than ODD install.
