Also,you were lucky to get it with PI coil spaces!

I know, right! With that luck, I should have went and played the lottery that day!

Re: Power supply build quality pictorial. part 2

Well, I'm bored and since here are some PSU geeks:
Could someone tell me the topology used in the following unint?

I still don't understand how that thing works (or how (in)efficient it could be)...

Anyone anything on the topology of that unit??

And why did we miss that PIC16C72A Microcontroller?

And that 8pin chip on the output side between the cables is just a serial Flash ROM.

And that chip with the cap glued on top is a FanXPert 3 Chip (whatever that is)...

What post # is that? I don't know if my eyes are broken or what, but I just can't find that post.

Well I don't know about being beefy, but it certainly has some "meat" on it. Maybe enough to last an entire winter.

Okay, silly Deer jokes aside, yes I have seen Deer PSUs this good before and even better. It all depends how much you paid for it. The cheap ones can be almost as bad as the L&C line. The better ones can be fairly decent: line filtering, PI coils on the outputs, and a real "35" size transformer.

Looks like my 'IT 300W' Power Supply.
That one with almost all caps bloated...

Well,considering this one powers a dual core system (and not a high end one) it's pretty good for the job. I know Allied/Apex does some good units. They're pretty rare here though - this was the only one close to an Allied,save for the 4 diode bridge rectifier and EI-33 transformer.

I could actually say it powers a "GIANT ROBOT". (Megas XLR )

The Delux is still powering the Athlon 64 3000+ system. I've got two more PSUs though - a Premier LC-B400ATX and a Premier LC-B450E. All those three have PI coils. The former has them installed by myself and the latter came with them already.

The LC-B450E also has a weird thing - one of the rails has actually two rectifiers in parallel - it's the 5v rail if I'm not mistaken. Why do that is actually past my ability to understand - why do that when you have the 12v rail?

No attachments this time because can't be bothered...

Does anyone know how/why Corsair uses the WT7518 on the modular PCB?

Hm, this Forum does not support using image links with thumbnails.
Weird...

Used the same code in another forum where it worked - here it didn't..

And I can't edit my posting somehow...


Well than, as atachements (didn't want that...)

Re: Power supply build quality pictorial. part 2

Corsair RM650x? Or maybe 750x.

[Stefan Payne]

Re: Power supply build quality pictorial. part 2

no

Look at those doughter PCBs...

Re: Power supply build quality pictorial. part 2

More than 750w ?

Re: Power supply build quality pictorial. part 2

Of course not.

P.S.,
We (the forum) encourage using attachments because images hosted off-site are unreliable.
As an example: You look at a year old thread to get info for a repair, only to get the dreaded "image not found" error! ... that can be quite frustrating!

Interesting PSU.
I would guess either double-transistor forward or full-bridge. Maybe the latter as there are 4 transistors on what appears to be the primary heatsink. The other primary heatsink probably has the APFC transistor(s) and rectifier(s).

I don't know what the PIC chip does in it (or why there are even so many ICs). Most likely using a programmable IC like a PIC chip was easier than trying to make all sorts of controllers work together.

Very nice power supply!
I'd definitely mod it to ATX standard and use it if that is possible. I'm pretty sure this will work forever with those caps and that built quality.

Oh yeah, I can see that now, RM650i. It seems almost the same as x. I've been sure it is definitelly not RM550 - that one is shorter.

Re: Power supply build quality pictorial. part 2

Hm??
They use another plattform for the 550W model?
