Re: ATX power supply not made in China

I'd be interested in this, but unfortunately I've never seen a non-China power supply either.

Re: LCD monitor backlight

It's been a long time since I looked into it but I believe the operating brightness makes a huge difference in the bulb's lifespan. I always keep my backlights pretty dim, I don't see the point...

Re: Linux penguin -- Best, comment, rage.

First unix I installed at home was FreeBSD 2.something. Command prompt only, worked fine but I only played around with it a bit.
Then tried redhat 6.2. Tried the Gnome GUI on that, didn't like it....

Re: SVHS Goodness

I've bought 3 $5 VCRs in the past year, and they were all fails.
The first one worked for about a month. The other 2 were DOA. Annoying.
I haven't seen an SVHS yet, I'd love to get one of those...

Re: CapXon

Even though the replacement caps weren't low-ESR, it still should have most likely started running (for a while at least) if caps were the only problem. There's probably another problem besides the...

Re: Gigabyte GA-7VTXE - Bad Caps

As it happens, I apparently did a diagram of this board. I found it on my hard drive, so I've attached it here (too big to post inline).



That's what I would do. The board was laid out for 9...

Re: Does anything less than 470uF usually bulge?

Weird - isn't ITOX a long-life brand? I'm amazed they'd use OST caps.

Re: Video adapters - bad caps

I think part of the reason for the cheap caps is because the add-on video card market is very gamer oriented. The big customers buy new cards every year, so long lasting parts aren't a necessary...

Re: Opinions on "ultra durable" Gigabyte boards?

True if you count Opterons, I think Supermicro also makes those. I was really thinking of desktop PC boards.
The high end brands make desktop boards for Intel, but they're only interested in...

Re: Opinions on "ultra durable" Gigabyte boards?

Those caps are really rated for 2k hrs at 105C, but the endurance increases dramatically with reduced temperature. So Gigabyte is just speculating that they'll run for 50k. That number doesn't come...

Re: What is the quality of Sapphire video cards? Do they use good capacitors?

A few years ago I ordered a Sapphire card (Radeon X1550) for my nephew's old computer. It had some cheap caps on it but it's good to hear they've apparently improved on that.

I'm annoyed that ATI...

I'm not talking about killing a virus after it's infected you. Loading a web site has never given me a virus.

Re: LOL virus fail.

I don't see how that's any different than Windows. I kill stuff in the task manager all the time.
What annoys me is that Firefox doesn't provide a clear way to close those popups without using the...

Re: Is buying a used SmartUPS a good idea?

I got the UPS about 1 1/2 weeks ago, or something like that.
It's working great. It didn't include the serial cable, which apparently is proprietary, but I got one of those later. It also didn't...

Re: Abit NF7

I've never traced out that board, but it's possible that 1 unique cap near the AGP slot might be the only cap on the AGP power supply output. If so, it might be overstressed with higher power cards.

Re: Identifying badcaps in a Xbox360

There's many machines (360 probably among them) that run so hot that cap failures are common regardless of the brand.
I've also seen blown Rubycon MCZ in a small form factor computer. It was just...

Re: 2 motherboards - 2 problems....

The Intel sounds like a power supply issue. Maybe also the Gigabyte. When it was still able to boot (but failing), did you check the voltage readings?

When you replaced the Intel board with the...

Re: Is buying a used SmartUPS a good idea?

Sounds like the used SmartUPS is probably a better choice than a new BackUPS. Seller looks reputable, so I've now bought one. Thanks for the help.

Re: Is buying a used SmartUPS a good idea?

Isn't deep discharge very bad for lead-acid batteries? I've only heard of that being good for NiCd or NiMH.

Re: Win7 sucks as gaming platform with CRT screen?

I wonder if this is a bug with the game(s), not the OS/DirectX. The game should be able to detect all supported modes but some might just assume you want 60Hz nowadays.

Try a manual override in...

Re: Is buying a used SmartUPS a good idea?

The history of my bad UPS went something like this:

1) Battery no longer held much charge. It was just good enough to deal with momentary brownouts, but not long enough to shut down. By this...

Is buying a used SmartUPS a good idea?

My old UPS (APC Back-UPS ES 725VA) has died. It might just need a new battery, but I'm in doubt. A few months ago I started getting a constant alarm (which I disabled in powerchute), and after the...

Re: Win7 sucks as gaming platform with CRT screen?

I don't see why video memory or age should be an issue with this. My old Geforce2 MX 32MB ran my CRT at 1600x1200 85Hz.

Re: Identifying cap manufacturer. M inside of a square

I did find a couple badcaps threads though:
