Recently acquired one of those silly Logisys acrylic power supplies and lucked into getting one of the "better" ones (most of an input filter, bridge rectifier instead of 4 diode treatment, OK-sized heatsinks, etc.) and wanted to fill out what I can on the board + get some decent caps on there (especially the primary side since I highly doubt the ones in there are actually 1000uf). My questions are:
1. How do I know what components to install re: the input filter? It seem to be missing an X cap, a resistor, and a Y cap.
2. Where can I find a good heatsink for the bridge...

Re: Power supply build quality pictorial. part 2
HEC-550TB. Same unit as [URL="http://www.hardwaresecrets.com/printpage/ADATA-BN-550-Power-Supply-Review/1268"]this thing[/URL]. Caps on secondary are all Teapo, except for one Su'scon on the 5VSB and other assorted minor caps. Primary is CapXon.

Intel 945GCNL help!
So I was building a PC for a friend of mine using some spare parts I had lying around, including the aforementioned motherboard. The problem is, I can't get it to boot from either hard drives or USB drives (yes the board supports usb boot). After trying fruitlessly to install windows from a thumb drive, I was able to install it via the DVD, however the PC always reboots when the OS tries to load disk.sys. Any ideas what could be going on? Specs below
Celeron e1200
Aforementioned motherboard
160GB laptop HDD
Windows 7 Pro
2GB RAM
Btw thanks in advance...

Re: Toshiba A135 stuck in sleep mode?
Which wouldn't be the worst thing in the world tbh, I got this for free and have no money invested in it. The re-flow makes sense since the last time it turned on it was when I moved it...

Re: Toshiba A135 stuck in sleep mode?
ATI Radeon XPress 200M is the video stuff, integrated. Weird thing is I've got it to work once before, now it just kinda laughs in my face.

Re: Toshiba A135 stuck in sleep mode?
Hope not, otherwise I'm out essentially the cost of a new one of these things.

Toshiba A135 stuck in sleep mode?
Just got a dead A135 notebook from a friend recently. Notebook powers on but displays no video through the VGA or external monitor, keyboard won't work (except the FN key until I press anything else), except for once where I got it to display on both until I closed the laptop. Tried removing hardrive, swapping RAM modules, clearing CMOS, all that good stuff, still nothing. Think it may be the magnet for the lid closed switch, but I have no idea how that thing works with the motherboard. Any ideas? Thanks in advance.

Re: Power supply build quality pictorial. part 2
Got two more wonderful units in yesterday, another Raidmax RX-380K, and one creatively named ATX Switching power supply. Both were pulled from machines, the former was a replacement for a dead DELL part, the latter from a generic PC case.
First up is the ATX Switching power supply:
As you can see, no creative expense has been spared with this one. The case is a lovely shade of matte gray, and the label is a very heavenly white. Fitting for a PSU that can deliver "450w" of power!

Re: Power supply build quality pictorial. part 2
Just picked this one up recently. Real Power ATX 235U
Nothing spectacular to look at, has a weird texturized feel on the casing, might be because it hasn't exactly lived an easy life.
Cable count is typical for a unit this old, 5 molex, one main, 1 berg.
Fan shot. Easy because this unit exhausts into the computer. It's a 92MM U.S. Toyofan unit that puts out 43.8 CFM.
Label shot. Nothing spectacular. It's an old unit, so low on the 12V side of things.
Finally...

Re: Power supply build quality pictorial. part 2
Yes, Powmax. They're one of the most famous PSU names, but for all the wrong reasons. They're so bad that they've become pretty much the gold standard for bargain-basement PSUs everywhere.
Everything in the above picture is a lie.
Cable count is the same as the rest, except for the addition of an AUX connector.
What a familiar sight. Tiny heatsinks, no input filtering, questionable quality capacitors, all hallmarks of a typical leadmen unit. Speaking of capacitors, primaries are JEE, as are...

Re: Power supply build quality pictorial. part 2
Next we have yet another rather infamous name: Bestec.
This particular example is the ATX-250 12-Z Rev. D, found in a new-ish HP.
Please excuse the blurriness. Camera was acting up at the time.
Cable count is the same as the Macron Power above.
Inside, again, looks decent enough.
So naturally some Jamicon capacitors had to show up and ruin the fun. You can't see it in this pic, but there's a few bloaters in there. Fan is also Jamicon, but I couldn't get the thing out of the...

Re: Power supply build quality pictorial. part 2
Got in some real marvels of engineering recently. All of them are broken in some way, two due to bad caps, one due to being garbage in the first place.
Up first is the delightful Macron Power MPT-251. Came out of some old FRY's prebuilt thingy. Having owned one of those wonders, I can say build quality wasn't high on the priority list for FRY's.
Label shot. Nothing spectacular here.
Cable count:
1 x 20 pin
1 x 4 P4
2 x floppy
4 x Molex.
Inside presents a bit of a...Last edited by cheese007; 12-09-2010, 11:01 PM.
