Hi I'm fixing my old g31m-s and I'd remove 5 blown capacitors, but I made a little mistake and I don't know where the 16v 470mf capacitor goes in this mobo (in this mobo only use a capacitor with these characteristics), I looking for a pic, a scheme or a help about it...thanks!

Re: Replacing a Capacitor in Asrock G31M-S
Most photos of that motherboard are taken from the topside looking down. That makes it very difficult if not impossible to see enough or any printing on the sides of the caps. i suggest that you put your multimeter in continuity mode and put one probe in one of the +12 (YELLOW) connectors on the main power socket (20 or 24 pin) that is on the board and the other probe on the +POSITIVE cap holes one by one until you find either the lowest resistance or a BEEP. YMMV.Last edited by Sparkey55; 04-06-2018, 09:28 PM. -
Re: Replacing a Capacitor in Asrock G31M-S
You state that you removed 5 caps in total. How many 470uf 16V did you remove? And what are the other 4 caps?Comment

Re: Replacing a Capacitor in Asrock G31M-S
Only one, four are 6.3v 1000mf, in this mobo only one is 16v 470mf (there are another four 16v but with 1000mf near the cpu)
I did remove:
1- 16v 470mf
4- 6.3v 1000mfLast edited by Quickgold; 04-06-2018, 10:21 PM.Comment

Re: Replacing a Capacitor in Asrock G31M-S
Asrock used GSC/Evercon for lots of the 1000u 6.3v units. Actually, any/all evercons should go.
Don't forget that Asrock marks the positive with a half-circle, not the negative! Replace a few at a time- easy to shotgun them and put em in backwards. Ask me how I know.
Caught it before applying power, and did not cause a "kaboom."
If it actually requires a 16v part, it'll be tied to the +/- 12v supply."pokemon go... to hell!"
EOL it...

Re: Replacing a Capacitor in Asrock G31M-S
Hi folks I didn't hold it until tomorrow and I replaced the capacitors following your advices....and success..by the moment this PC is alive, is alive, is alive
....Thanks!

I wonder the resistance value of the mlcc capacitor between atx24 pin and usb3.0. -
HI I have a PC using a Corsair cx600 psu & ASRock B450 Pro4 mother board that won't power on after a shutdown (replaced a dead drive in a raid array) Not the boot drive.
With most things unplugged, including the 24 pin ATX connector, but not the ATX12v to cpu, I have +5.01V on the +5vsb pin 9 from the PSU. When I plug the 24 pin back in to the mobo, the +5vsb fluctuates between 1.1v & 1.9v.
Not sure where to go from here ?
Is the PSU at fault or is the mobo causing the problem
Look forward to any help :-)
If I plug the 24... -
I replaced some capacitor which is located on optical pickup pcb which is shown in the table below(PCB #2).Because it have been out of order.
Now,It works very well,But I just have found that all caps (6svpc100my and other part number as well) ,which is shown in the table below, has ultra-high ripple current spec.
It is not able to obtain any capacitor which can be a substitute for this ultra-high ripple current nichicon capacitor.
So I replaced it with samxon and rubycon's general capacitor(GP,YXA series).
I know that these capacitor will not last as long as nichicon capacitor... -
I desoldered samwha NF capacitor(50v 5.6uf) from PCB circuit of 29inch CRT TV which have symptoms of no display after I heard sound of inrush of current to TV whenever I switch on this television.
I measured ESR value of this non-polarized capacitor(samwha NF capacitor 50v 5.6uf) by means of MESR-100 ESR meter and It displayed 0.3 ohm
And When I measured its capacitance with digital multimeter and LCR-T4 Mega328 meter, It displayed 10uf from DMM and 8uf from LCR-T4 meter.
I found catalogue of samwha capacitor(samwha-catalogue_3.pdf file), which is attached to this thread,... -
When I tried to repair LG 29 inch CRT TV, I found that the ESR value of samyoung SMS capacitor(160v 2.2uf), which is very close to D1879 transistor, is 6 ohm.
Judging from above ESR Meter Table,I think It is necessary to replace this sms capacitor.So I visited local electronics shop,and I purchased 160v 2.2uf rubycon YK capacitor.
But when I browse through rubycon YK datasheet,I found that there is no ripple current rating for 160v 2.2uf specification. But On the contrary, I found 39 mA ripple current rating for 160v 2.2uf SMS capacitor.
Rubycon YK DataSheet (b...
