While my HX850 may have 10 places to plug in the cables, each with a 12V line, it still has but one 12V rail which powers all the connections. Rails themselves aren't modular, it's the cables.
I saw a dual 12V rail, 650W the other day which 12V-1 rated at 20A and 12V-2 at a mere 6A.
Yep mate the Thermaltake I have in the tester at the moment has dual rails one at 24A and the other 22A but I think the 24 pin is on the larger rail.
Anyway I suppose we have hijacked this thread a bit eh
Voltage is only part of the psu output equation. You have to know what it is putting out in current, or amps. A psu may test with good voltage readings but fail on amp output causing all sorts of problems. You can test for amps with a multimeter but it well require a shunt. Good meters may have a internal shunt capable of up to 10 amps or so, but nothing close to what a pc psu can supply. Having a "test" psu available can save hours of troubleshooting. It doesn't need to be a real expensive high end unit, several good options in the sub $50 area.
Most of the time when there is a TDR in the mix driver crashing and recovering it is a issue with the GPU
I had that same issue for weeks till it came down to the GPU the PSU was fine
I recommend sending the GPU back 6870 display driver has error every 3 mins
Which is what I have been saying all along Mad and yes I have had some more expensive multimeters that will read up to 20A in DC and 10A in AC. There are to ones that do "clamp" around the cable but are usually quite expensive and not what we would probably want for our purposes because they measure AC current only How does a dc clampmeter work? | Electrotechnik - The Website on Electrical Engineering
Haha that's not a problem. The more you guys got back and forth, the more I learn.
Hey Solarstarshines, thanks for the reply. I was thinking that in the back of my mind but I was trying to convince myself it wasn't. I don't really want to have to return something to Asus and deal with the whole process. If the problem still persists when I replace the PSU, then that will be my next step.
Hi All,
Just a quick update. I ordered a new PSU from newegg.com yesterday morning and it should be arriving here sometime today. Again, that's the best thing about living so close to their warehouse, standard shipping feels like overnight shipping. Anyways, I will install it tonight and report my findings. If the problem still exists, I will look into returning the GPU to the manufacture.
Thanks,

Just to clarify something which some of you may not be aware. The power good signal is generated by the motherboard to let the PS know the motherboard is happy with the supplies it is getting, if that signal is out of range the PSU is 99% of the time defective 1% of the time the motherboard is the issue.
Gary I do not agree on you 12v single rail. In the event of a short there is no current limiting and bang goes all your stuff with 100 amps through it. I always use Enermax PSU. I put this baby in my upgrade I have done in the time this thread has been going....ENERMAX ERV1000EWT-G 1000W ATX12V v2.3 / EPS12V v2.92, v2.8 SLI Ready CrossFire Ready 80 PLUS GOLD Certified Modular Active PFC Power Supply - Newegg.com
