I'm using Akor's method for testing vrms on my a7n8x.

I'm at step 3 and measuring resistance from my power pins on motherboard to the input of the VRMs. Should I be worried that I see a small amount of resistance. Akor mentions with new caps there should be no resistance but is that just an anal or ideal measurement????https://I'm using Akor's method for ... from my power

On a side note, I opened another antec 350 watt power supply that i had on the shelf as labeled bad. What a mess that is inside. A cap leaking nightmare.

I was hoping someone could tell me if the blue esr tester or please list the one you have that is helpful for testing onboard capacitors. If i'm going to order caps, I want to check the seemingly good rubicons too and get my order done in one shot.

Re: Multilple Boards and Very HOT SOUTHBRIDGE S

OK, I measured all and they vary from as low as 5.09 to 5.17 with the
xconnect 600 watt being the highest. I even measured a 4th powersupply that I have running to post here that falls inbetween. Is it possible that with a load on the P.S. these readings would change?

Otherwise, these readings are acceptable correct?

Re: Multilple Boards and Very HOT SOUTHBRIDGE S

So according to you, I would then be testing 3 different power supply's and a couple antec's. I may just do what you say. Of course I would have to strongly believe that not one of my power supplies are in spec.
My power supplies are...

Antec true power 2.0 480 watt
Antec Smart Power 350 watt model SL350
xconnect 600 watt

Re: Multilple Boards and Very HOT SOUTHBRIDGE S

Or most likely have I used my boards caps to and beyond the lifecycle of even a good rubycon CAP?

No sign of failure but if a cap is like a battery... It's time to replace my motherboard Caps?

Puzzling Hot Southbridge Phenominon...

I've got two a7n8x deluxe and 1 gigabyte GA-7vAXP board. All setup independently and all suffering from can't hold my finger on the southbridge without burning it. These boards did not used to be this way and are all socket A with rubicon capacitor. Newegg sought after boards and ran very well for many years. The capacitors look mint on all these boards. 1 board is dead and i'm assuming the other 2 will follow shortly. Installed heatsinks and still too hot to handle. All boards have the Nvidia MCP southbridge and when the ran properly, they...
