Its shorter, not so many things inside.

Re: Power supply build quality pictorial. part 2

Picked this up at a thrift store for $2.50, decided to actually get decent pics of a PSU for a change.

It's a Xigmatek NRP-602. 600W, 80+ Bronze, made by HEC.

Not a bad looking chassis, all dark grey with nothing special.


Actually has filter caps, plus the PCB connects using spade connectors rather than direct soldering. That's not something I've run into a lot.


Once inside the board states it's a "600TE" PCB.


Caps are a bit interesting. There's a mix of Nippon Chemicon, Teapo and "SK". Not sure who made the SK caps, not Teapo as they're 105*C rated.


Here's a HEC branding


Soldering...could be better, not the worst I've seen.


Fan's just a Young Lin Tech DFS132512H. Seems it's been used in a few Cooler Master PSUs as well.


Here's full res pics, rather than 1024px downsampled. Didn't want to make you guys wait a week for the images to load: http://imgur.com/a/OAhZ6

Re: Power supply build quality pictorial. part 2

The 105*C "SK" capacitors are likely Su'scon.

Re: Power supply build quality pictorial. part 2

The 105*C "SK" capacitors are likely Su'scon.

Looks like that'd be them. I guess that means this PSU was built with decent caps, probably alright caps and less than favorable caps.

Not a huge deal, this'll be reserved for those mid range systems that'll draw maybe 300W on a bad day. I'd never trust a Xigmatek for a proper gaming rig.

Re: Power supply build quality pictorial. part 2

I'm almost certain they're Jamicon.

[Wester547]

Re: Power supply build quality pictorial. part 2

Jamicon's SK series is rated for 85C rather than 105C.

[Stefan Payne]

Re: Power supply build quality pictorial. part 2

I'm almost certain they're Jamicon.

Hec doesn't usually use Jamicon but they use Sus'scon. So it's very probable that those are Sus'scon caps...

Had such unit on the Chroma 6000 ATE btw.
Ripple was rather poor on that unit...
20%, 50% and 100% load:

Oh dear...

I haven't seen the voltages on a scope though, so I can't tell how bad it actually is or if it's just some random EM noise bullshit that just looks bad but really isn't.
Can't say for sure.
The HEC SIlver Plattform of that time had some problems with somethings like that so it's possible it's the same with this one...

Re: Power supply build quality pictorial. part 2

Weird to see HEC use a Japanese cap for PFC filtering...I've only ever seen them use CapXon. Yeah those are Su'scon caps, HEC is known for using them. And Su'scon always outlines the capacitor series letters, as seen in 4th picture on that little black capacitor.

Re: Power supply build quality pictorial. part 2

They're doin it for some time now - since the first Cougar units...

Re: Power supply build quality pictorial. part 2

Hey guys

I am in the middle of recapping an old Jeantec Storm 700w unit I bought way back when in 2007.

It was used for a couple of years as my main PSU during the Core 2 Duo era then relegated to server duties for the last 4 years.

It has never skipped a beat but the limited reviews about were mixed on it, I thought I would ask what people thought of it? I am still not so clued up about PSU design.

The OEM is Sirtec.

Apologies the pictures are half way though removing caps.



Main filter is a Su 'Scon LZ 470uf 400v (I have left this)
The rest were Teapo,
1000uf 6.3v x 2 (Near transformers, one vented)
3300uf 10v x 2
3300uf 6.3v x 2
1000uf 16v x 2
3300uf 16v x 1
470uf 16v x 1
Few other 10-2.2uf

Have recapped with
1000uf 6.3 Panasonic FC x2
2700uf 16v FC x4
1000uf x 2 16v FR
3300uf x 1 16v FR
470uf x 16 FR
Few other low values with identical FR caps.

Hopefully will last another 8 years, what do people think of it?

Looks quite decent. Should last many more years with the recap (probably even more than with the original caps.)

The only problem you *might* run into the future is with APFC blowing itself - either due to it killing the primary 400V cap or just because APFCs like to fail in general. But when that happens, you just replace the primary cap and remove APFC MOSFETs, and PSU is good as new again. (actually even better, IMO.)
Of course, you also *might not* run into that problem ever.

Re: Power supply build quality pictorial. part 2

Well it powers a i7 920 and a 7870 while running stress on the GPU and CPU at the same time for a couple of hours.

Fan got pretty loud and the readout on the back got near 400w however accurate that is.

Not bad for a old unit

Re: Power supply build quality pictorial. part 2

Have had this sitting around broken for years. Doesn't turn on. No voltages at outputs. Fuse OK.


It has a watt meter display on the back.

Would like to figure out what is wrong with it.

Re: Power supply build quality pictorial. part 2

Its a Sirtec like the one I posted above

Pics of inside? Hows it look?

Apparently some browsers aren't displaying the inline images I posted in the forum.
I think everyone can see attachments, I'll attach some now.

If it wasn't for the modular output connectors and the name on the side, I'd think I was looking at mine...lol. Oh, and the fact that mine doesn't turn on.

Re: Power supply build quality pictorial. part 2

Got something new =)

An old Enermax.
A not soo old Liteon
And a very very old HEC.


The Liteon seems quite nice, besides that cap right next to the secondary heatsink...

Pics to come.

[Stefan Payne]

Re: Power supply build quality pictorial. part 2

Here the first.
Take a guess who did this PSU.
I won't say...

Very high heatsinks, you can see that this was designed with one 80mm fan in mind.
Caps are ltec on the primary side and mostly Taicon with some SamXon on the secondary side.
Soldering is also beautiful...

And it's a 300W with just 19A on +12V...

[Behemot]

Re: Power supply build quality pictorial. part 2

Umm, maybe, with all the LiteOn signs, let me guess…LiteOn?

That's a VERY nice looking unit!

LiteOn is like Delta! The way their designs are made, they look really similar. (good quality though!)

Those are some high quality pics as well!

Dang, you beat me to it by a few minutes!
