Re: Enermax to stop making PSU's, will only make stickers?
Just picked up a Revolution X't in 430W, and can simply peer inside and see CapXon.... yep, the best part about this PS is the stickers....

Re: Hurco Hawk5 CNC, PC Power Supply Needs R&R
A little update:
The Hurco machine has not been used a whole lot since the rebuild, but certainly enough to note some other issues...
1) Normally difficult time getting the axes to calibrate upon startup, sometimes 5+ minutes trying & retrying... hoping to get beyond a "marker not detected" message that would keep coming up.
2) Quill/Z-axis is often just twitchy and will shut-down the servo-side due to positioning & movement-faults... then there's those scary moments when it just starts rapidly...Leave a comment:

Re: Hurco Hawk5 CNC, PC Power Supply Needs R&R
Hi there,
Yeah, it actually was(as we received it, at least), and somehow functioned just fine all these years(previous owner had alluded to having some heat issues, and installed another case-fan on the electrical cabinet housing). I had put my hand on it once after a little test run and it certainly was uncomfortably warm.
However...
upon this latest re-assembly I did use some thermal-transfer-adhesive to bond a 2x2"(perhaps larger, still) aluminum heatsink to it, and that ought to help out with any temperature...Leave a comment:

Re: Hurco Hawk5 CNC, PC Power Supply Needs R&R
I don't exactly get it, but I do tend to take the jackass route in so many situations, and, honestly, my tendency towards that does frustrate me as well.
Anyhow....
So I did end up grabbing a Panasonic FC series cap for one of the 'middle' positions, and some Nichicon PW's for the "right side" caps, but the rest were filled in with Rubycon ZLG's. Oh yeah, and then there's the mains, those got replaced, too. A little O-scope testing on the +5V, and basic multimeter checks for the other outputs.... slap the power...Leave a comment:

Re: Hurco Hawk5 CNC, PC Power Supply Needs R&R
Bah... now I'm seeing where I've already goofed up, it would seem. I need to be learning about cap-series, and when Low ESR vs 'this trait' vs 'that trait' is to be desired more than what I was looking at/for in my purchasing. Stoopid.Leave a comment:

Re: Hurco Hawk5 CNC, PC Power Supply Needs R&R
Hello again,
Well I did a little snooping around my "badcaps.net"-supplied capacitors, and found the proper caps(performed some voltage testing, too) for most of the caps on the board.
Not meaning to be brazen or insolent, but I did go ahead and purchase what caps seemed sufficient to the task at hand(highest hours @ highest-temp, etc). Of course, if this idiot has chosen wrong, I welcome your criticism, and will likely be purchasing whatever is deemed better.
These are what I invested in:...Last edited by mazade; 03-24-2015, 10:21 PM.Leave a comment:

Re: Hurco Hawk5 CNC, PC Power Supply Needs R&R
Heheh, I've messed with a lot of computers myself, and never seen one operating naked like that one is/was... perhaps I'll thermal-adhesive-bond a decent one on there.
So, forget the yellow caps, ok.... what about that white one hiding behind those resistors.... Sprague 2.0uf 250V??
Thank you.Leave a comment:

Re: Hurco Hawk5 CNC, PC Power Supply Needs R&R
Thanks again for the contributions.
Hmmm, any direction(s) regarding these caps found on the board...?
Standard 3.0uF 200v
Sprague 2.0uF 250v
Didn't end up replacing anything last night, just stared at it and copied down info.
Regarding the 'smaller' caps in the center(likely the reason for my delayed starting); should I replace them with 'similar value' or 'same value' capacitors...? Ex. one of them is 25v 100uF... I have 25v 220uF ... I understand that maintaining these values is critical...Last edited by mazade; 03-23-2015, 06:06 AM.Leave a comment:

Re: Hurco Hawk5 CNC, PC Power Supply Needs R&R
Good input, thank you both.
Heh, didn't even notice the small caps in the center there, doh!
Where might I acquire the monster input caps??
I did acquire the 'badcaps.net' general power supply recap kit some time ago... should that suffice for most of these?
The unit has been running recently too, I actually had it all up and running a few days ago, spindle, servo's and all... I just haven't cut(milled/machined) anything with it yet. I suppose lucky may be a fair enough description...

Hurco Hawk5 CNC, PC Power Supply Needs R&R
Hello to you all,
We've very-recently acquired a 1996 Hurco Hawk 5 SSM(single screen) CNC Mill, and are doing a little clean-up prior to putting it in service(quite anxious).
While we have seen this mill in operation prior to purchasing, it was learned from the prior owner that they kept the PC-side of the machine on continually, and that it 'always' had issues starting cold(lower temps and/or starting up for the day)... this being the PC-side too. These machines came with an integrated 486 board & setup for handling the G-code & Conversational Part Programming... basically... -
Re: Power supply build quality pictorial. part 2
@mockingbird -- everything I pulled out was replaced with appropriately spec'd Rubycon's from badcaps.net... the particular line of Rubycon's I don't recall, and didn't think to check as I figure anything-Rubycon is better than teapo's or capxon'sLeave a comment:

Re: Power supply build quality pictorial. part 2
Just the other day I did a recap on a nearly new Antec VP450, containing mostly Capxon & Teapo crapacitors. Replaced with Rubycons from here.
One thing I may want
.... I didn't replace any of the tiny caps I saw(50V 10uf, 25V 22uf, etc...), and from what I've read just a bit ago, it's a better idea to replace even these smaller ones since they are a junk brand and very prone to fail...?
This is intended on going in an AMD X6 build... moreso for light server usage, not gaming. Pics are of: craps removed,...Leave a comment:

Re: Secondary MCP61PM-HM issue & my work-around
I have this board out of its original case and all, just picked it up bare on ebay for cheap.
OK... so I'm a dupe regarding their weird setup...
I just dont like the thought of that thing being able to heat up, at all, especially with that sensitive Nvidia chipset that doesn't have any active cooling for it

Re: Secondary MCP61PM-HM issue & my work-around
Really? Well, why would the "system fan" not spin at all? It's a small crossflow fan, and the 5V that's being input doesn't even begin to turn it over...
The CPU fan spun so weak that it would hardly move, and if it was stopped(by a finger or something) it wouldn't even start back up on its own.
Perhaps you're right about that, but yikes!Leave a comment:

Secondary MCP61PM-HM issue & my work-around
This will be the second MCP61PM-HM motherboard that I've received(deliberately) and recapped with good results... yet there is still an issue which seems to have lingered on one board, but perhaps both(will find out this week I hope).
1. the System Fan plug is only putting out 5V on the + , not the 12V that it should be. Fan will not run, and system constantly gives the "System Fan Has Failed" message upon boot-up.
2. CPU fan plug is not putting out full 12V either, but I have a harder time checking the actual voltage put out since the system will shut down if it receives...Last edited by mazade; 12-27-2011, 01:58 AM. -
SX280 not powering on; amber blips once, da-2 fades off
Well, here again with another "it's not working after I recapped it, thinking I had this one in-the-bag".
SX280 Phrizbee, I recapped it's twin sitting at the same work-station only a month earlier, worked like a dream(and still is).
My friend who got to this current problem initially opened the case to find the chipset-heatsink-clamp-hold-downs !?desoldered?! from the motherboard, wow.
Well, on site, he re-soldered the spring-clamp-hold-dowm to the board thinking that would fix the issue of it not turning on, and it still didn't work....
*he doesn't play in...Last edited by mazade; 10-11-2011, 10:06 PM. -
Re: Another A8V Recap - I screw something up?
well about all the KZG's, I left some of them that were dedicated to unused USB connector spots, and to the audio chips/amp interface.
I did perform the CMOS jumper reset earlier, before swapping bios chips.
I noticed the battery is still a few hundredth's above 3V when I'd checked... maybe change-out still?
I'll likely be grabbing the 5X optical loupe and taking a close look at things : /
Thanks ^_^Leave a comment:

Another A8V Recap - I screw something up?
Hi there,
Looking for insight from you experienced gentlemen... I'm hoping I missed something.
Asus A8V Deluxe
For its owner the thing has become less and less reliable, powering off/freezing/dying becoming more common, it sounds like it has sat unused for 6 months to 1 year.
I get my hands on it and notice that it's loaded with KZG caps, like 20 of em;
6.3V/820uf things. So I get on here to learn, and then follow standard procedure. A bunch of Samxon 6.3V/820uF caps for most places, Fujitsu Poly 2.5V/820uF caps for Vcore, Samxon/Rubycon 6.3V/1500uF... -
Re: Asus Crosshair 1.04G Poly/KZG/nForce590 Challenge
As well, thank you.
Considering all the other motherboards floating around ebay & wherever with bad caps that can be acquired for 'a song'(maybe 'a song and a dance') and fixed with a few dollars of AMAZING caps, this thing isn't really worth the risk of reballing/reflowing and finding out that it might be hopelessly lost anyways, correct?
Next step for testing purposes anyways is to swap out this beefy-looking crosshair board with a re-capped, and nicely functioning but slimmed-down-looking, MCP61PM-HM,...Leave a comment:

Re: Asus Crosshair 1.04G Poly/KZG/nForce590 Challenge
Thanks for the responses gentlemen.
I was suspect of the 8800GTS myself and did swap it out with a good 'ol Diamond Stealth 3D 2000 PCI card... still the same weird issues and freezings.
This Crosshair board has the nForce 590 chipset if I understand correctly.
About the 8800GTS, what is understood to be flawed in/about them?
I did find myself looking over what caps I could actually see on that card...Leave a comment:
