As topic, or any recommend?the caps size is 10mm in diameter.thanks

Re: Can 25v 330uF caps replaced by 6.3v 1000uF?
Is that an old Gigabyte motherboard? If so, then from what I've read around here I think the accepted answer is "yes".
But in the general case, the answer would be "no". -
Re: Can 25v 330uF caps replaced by 6.3v 1000uF?
Depends on what voltage it's on.
If you use 6.3v caps then the voltage they are on [+ ripple voltage] must be less than 6.3v.Mann-Made Global Warming.

Yup, its Gigabyte old motherboard GA-8IDML. support socket 478 and Sdram.Originally posted by gdement
Its 3 * 3300 choyo vrm capacitor is bulged and i am planning to recap it and other badcaps too. Weird thing is Gigabyte use Sanyo OS-CON and Panasonic FJ capacitor parallel with the Choyo caps at VRM secondary side, I wonder why their engineers do so...Comment

OS-CON + FJ + Choyo in the same VRM is indeed strange.Mann-Made Global Warming.

If the voltage tests out, then I think you can use the 1000uF 6.3v caps. Haven't done it myself but many people here have posted about making that sub and it seems to work fine for them.Originally posted by retnuoc
In general you wouldn't want to boost the capacitance that much though.Comment

Re: Can 25v 330uF caps replaced by 6.3v 1000uF?
These are 3300uF Choyo not 330uF.
I would stick with 3300uF caps.

I know I've been a little scarce lately (like the last 2-3 years), but I'm still here and still doing my thing with fixing PSUs.
For today's considerations, I have a Seasonic B12 BC-550 [A551bcafh] 550 Watt ATX power supply for you (click on links for full size images).

It's a modern ATX unit with fixed (non-modular) cables and an 80-plus bronze certificate. Here's the label:

Howdy folks,
I have an Optiplex GX260 that blew a couple of those troublesome Nichicon HM series (ultra low ESR) electrolytic capacitors. Because said caps are obsolete, they are pretty much impossible to find on the market; I did find a listing for some but I believe they are counterfeit. I feel the easiest thing to do would be to replace all the blown caps with polymer ones. I am by no means an expert in electronics, and I've found a fair bit of conflicting information, so any guidance or confirmation would be greatly appreciated. While from a practical standpoint it's not worth... -
Normally, I never post repairs this quick after I do them, because… I am usually very slow.
But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though. 
I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...

Hey guys, bit stumped with this laptop after replacing 2 blown components i.e., MP86493, MP2979A.
To begin with, this laptop was dead-dead.
Now with replaced (visibly) blown components, i do get some progress; after connecting battery or main cable;- am getting white power led
- 5-long-flashes on CAPS Lock and NUM lock
- then, fan full speed
- CPU heats up some (smaller die PCH, does not)
- always constant black screen no matter what's tried
- no USB recognition
- no HDMI output
I tried... -
LG 42LB5D (42LB5DF-UL) from 2008-01, unit is in good shape and no obvious heat damage or cracked solder on the boards.
Problem:
On first power-up the power LED flashes green about 18x and then stays solid. No backlight or image is present. Click power button, wait 10s for a click and the LED turns red. Wait 1-2s and hit power again and maybe it'll power up fully after 6 green flashes. If it doesn't light up on the sixth flash then the cycle repeats.
It seems that if the mainboard power is left on for a few minutes (solid green power, no backlight, no image)...
