Your spare PSU Stash

Re: Your spare PSU Stash

My only working spares are a handfull of 250W or less Clay Pigeons... I do have an early production (sorta) 450W TGGI (made by super flower) with all sorts of cool features. I also have a couple old 5V heavy 300W units (a Compaq badged delta and a hipro made AGI). All my good ones are dead (a 550W acbel, two 850W OCZ's, etc).

dmill- I'm jealous... there's quite a few gems there (a 1200W no less!). The biggest I ever owned was a 950W Tuniq that I fixed and later sold to a classmate... kinda wish I had it, as if I ever upgrade my main rig's GPU's, I'll need more than the barely sufficient 600W in it now.

PSUs currently with their PCBs out waiting for a re-cap (And they've been waiting for quite a while - until I make a big order from Neward):

Re: Your spare PSU Stash

I have collected so many that I had to store most of them in the attic!

Wow! That's a lot. Now I'll have to go and find my bottom jaw.

Re: Your spare PSU Stash

WOW! Nice stash! I want to see the other side with all the wires

And I thought I had too many...

Re: Your spare PSU Stash

Yup, that's me. But I think c_hegger confirmed it once, too.

Nope, not me. I haven't load tested a Sirtec PSU from before they became Sirfa.

Re: Your spare PSU Stash

Maybe I don't read enough PSU reviews, but I think it would great if someone took an APFC PSU, measured it's efficiency, then removed the APFC and measured the efficiency again. Has this been done before? If yes, then I'd like to see that article.

I haven't heard of it. But considering until recently most PSU reviews only went as far as to check voltages in the BIOS and sometimes with a multimeter too, I'd be surprised if anyone has done something that interesting.

I'm sure someone here could give it a try, though.

Re: Your spare PSU Stash

APFC might be more efficient but the APFC circuits are also more stuff to go wrong...

All energy conversions have losses. In this case, APFC is just an extra conversion. So I'm not entirely convinced that APFC is more efficient. I think it's just that newer designs are more efficeint (i.e. single-transistor forward is better than half-bridge, then 2-transistor forward better than single-transistor, and etc.)

I should shouldn't I

Might as well. If I ever come your way, I'll buy an entrance ticked .

Maybe the caps are failing. Wasn't it you that said Sirtec PSU's have an insanely picky feedback loop?

Yup, that's me. But I think c_hegger confirmed it once, too.

The Task PSU had 1 bad Jenpo cap on the 3.3V rail. But I replaced it, and that wasn't what caused the oscillation problem. I didn't experiment too much with it, but I remember (from a while back) that it didn't like it if you added an extra cap on the 12V rail (it has spots for 2x 10 mm caps, but only one is used and is usually 1000 uF... the other was 100 uF - yes, just one hundred uF). And although it seemed to be only stable with the stock setup, even then the regulation was quite bad.

Can you upload label and internal photos of that psu please?

I'm waiting for a sunny day...
No, actually the problem is that I am too slow and too lazy and never get things done on time, so I never get to post all of that stuff on BCN. I actually have the pictures already.
... unfortunately, yes, you have to hit me on the head for me to do anything right
But I promise you I'll do it someday. I really want to as well.

The Task PSU is built by Sirtech, but it has very crappy regulation and oscillates BADLY with a 12V load.

Re: Your spare PSU Stash

As long as it's not a lump of Chinese concrete!

Haha so true usually those aren't reliable though

[Agent24]

Re: Your spare PSU Stash

I like an old reliable design with PPFC

Re: Your spare PSU Stash

Here, on 230V, that's not an issue, as the coils don't get as hot.

So true. It seems that the booster coil is the most likely thing to fail in a APFC circuit. With proper placement, I like an old reliable design with PPFC

Re: Your spare PSU Stash

I have way too many...Either to have on hand, waiting to sell, or just laying around because I recapped it

Going for The PSU Museum title?

I have mostly junk. Just a few good worthwhile units. Namely, a MPT-301, a HiPro HP-P2507F3P tank in a RaidMax RX-380K case , Bestec ATX-1956D, a Morex MXA-235PTF1, and a LiteOn 250W unit (forgot model).

I also have a PowMax LP-6100D and a Task TK-930TX. Not sure if I should consider these as decent, though. The PowMax... well, it's a PowMax, need I say more. I wouldn't trust it even with a recap and a proper 5VSB circuit. The Task PSU is built by Sirtech, but it has very crappy regulation and oscillates BADLY with a 12V load. I think a Deer DR-250ATX that I found last year is better than both of these. At least I know I can trust it up to 250W and it will have good regulation.

as many of the "old-school" designs... are not worth anything to me (other than parts).

Why?
There are so many excellent "oldschool" designs without PFC. Just because they lack PFC doesn't mean they are inferior. In fact, many of the better ones (think OEM Delta, HiPro, and Lite-ON) are simple, yet bullet-proof tanks, especially with good caps.
I think you are missing out.

Re: Your spare PSU Stash

I decided to only keep units with active PFC

How come?

I've got a couple of boxes of PSUs like that. Need go through and weed out the good ones and test them. The crappy ones I am keeping for spare parts and projects.

Pictures?
