Re: PC Power Draw?

Not quite sure... but I think that Sencore (or just any AC ammeter) likely just measure the voltage drop over a current shut and then amplifies the magnitude of that to give a reading on the scale.

Re: The "leaked" Windows 11

QTF! :group:

Heck, I'm still on the line about Windows 7 (Vista for sure sucked.) I know a lot of you will think I'm crazy to say this... but I just can't get used to 7 for certain things, like...

Re: PC Power Draw?

Same here.
Currently sitting in front of a HP Pavilion DV6000 laptop (the C2D ones with Intel chipset, luckily, and not nVidia shitset) that averages about 20-25W at the wall (real power, that is),...

Re: Alienware laptop issue

Sounds like a short-circuit or overload in the laptop is causing the power adapter to shut down. Either that, or perhaps the power adapter is bad (bad caps?) and shutting down under any significant...

Re: Max resolution out of DVI-D port.

I bought a cheap DVI-D to HDMI cable from Newegg a few years ago. A lot of user reviews mentioned that they could get sound through the cable. However, I have not been able to confirm this with mine....

Re: CD Shows No Content When Making ISO Image

Another thumbs up for IMGBURN from me. https://www.badcaps.net/forum/images/icons/icon14.gif

Re: Compaq PDP-121P - Baked MOV

Yes, looks pretty normal. If the TT tester was able to identify it, then that means the MOSFET is actually working.


Looks like the MOSFET between the 12.8V and 12V rail is used either as a...

Re: Why does my Seasonic SSR-500GB3 whine??

Good call!

So, if the PSU is making whining noise both in standby/soft-off mode and aksi when turned On, then that means the whining noise is likely coming from the 5VSB circuit (probably the 5VSB...

Re: The ghetto mod thread

That sounds about where I would be drawing the line too.
Q6600, OC-ed or not, can peak up to 130-140 Watts probably. HD4850 and mid-range HD5k (i.e. HD5770) are also another 100-110 Watts. So that's...

Re: Chieftec GPS-550AB-A (Delta OEM)

Well, I see an 8-pin IC on the primary in that first picture. So I don't think that PSU uses a 2-transistor 5VSB (but check what is written on that IC first!) The small cap next to it (47 uF) is...

Re: Why does my Seasonic SSR-500GB3 whine??

Does the whine noise change under different loads? (Try something like AIDA-64 or OCCT to load the CPU only, GPU only, and then CPU + GPU to get maximum load.)
If noise changes with load, it's...

Re: Chieftec GPS-550AB-A (Delta OEM)

For the endurance alone: yes.

VY series are only rated for 1000 hours (at 105C, max applied voltage, and any diameter, it looks like.) The ripple current is also only 1170 mA for the 16V, 3300 uF...
