Re: My Latest 8-core Project

Be careful - you might get some serious computer tan now! :group: ;)

The monitor on the left looks barely on the edge of the desk, though.
Next up: bigger desk upgrade? :D

BTW, often there are...

Re: unknown (solid?) caps on MSI "military class" graphics card?

No, it would be fine.

BGA memory chips like these are generally designed to cool through the solder balls on the under side. Thus, with a properly-designed PCB with large ground and Vcc planes,...

Re: Power supply build quality pictorial. part 2

Nice solid-looking unit.
Only thing I will nick it for is the 270 uF primary cap - seems a bit on the low side for a 550 Watt unit. 330 or 390 uF would have been preferable. More if the PSU is...

Re: best cheap/free scores 1.1

Ah. Monkey technicians at work somewhere again, I see. :group: Just the same as that PC I found a little over a week ago. (Pictures still pending, lol. :D ) Some people just don't know how to use a...

Re: Directly replacing NiMh cells with Li-Ion cells - bad idea ?

If I had to guess... probably so that they could use a cheap wall-wart adapter for the charger instead of a more beefy SMPS adapter. Make sense from a cost stand-point at least: just tell the user to...

Re: Elite 945GCT-M3 dead

Hmm.. so maybe someone did work on it indeed. I find it strange, though. Most repair shops don't do this kind of work. But maybe someone was experimenting with it.

That said, it is possible to...

Re: xbox one-s

Yeah, I've had that idea for a long time now, but never tried it. Should work fine, obviously, as the CPU heatsink is a lot better equipped to handle the heat the GPU produces than the stock (v1 or...

Re: unknown (solid?) caps on MSI "military class" graphics card?

Well, I don't know for sure, but I'd say most likely they do.
Like you said, there has to be a reason why manufacturers use Japanese polymers in the CPU VRM. But it may not be because they are more...

I use pencils almost exclusively when drawing/sketching almost anything. Got about a pound worth of them in a bag, most of which came back from when I was in middle school and high school - typically...

Re: xbox one-s

Interesting.
Hey, I see more potential work (and customers) then! :D
Plus, I'd much rather be replacing MOSFETs than doing BGA work with the old Xbox 360's... which would always come back (or get...

Re: best cheap/free scores 1.1

Ha! Cool to see someone still cares about old tech like that (I know I still do.) :)

Regarding the VX700... why do you say you think it needs a recap? Picture too dark or something?

Re: OCZ Fatality 700w PSU Repair Help

Ha! Yeah, two GTX 285 cards will indeed double as room heaters. 204 Watts TDP per GPU x 2 + the CPU TDP (around 100W?)... and that's indeed 1/2 KW of heat to get rid of (in the worst case, of...

Re: Elite 945GCT-M3 dead

Not trying to undermine your troubleshooting experinece, but are you sure someone actually tried to replace the Southbridge before you? I find that very unlikely. If you still haven't cleaned the old...

Re: best cheap/free scores 1.1

WOW!
And despite having the same core clock as the Q6600, I bet it runs most things way faster, probably due to optimizations and updated instruction sets. Makes it that much more of worthwhile...

Actually, it's funny that you mentioned this. :D

The above post was actually typed a couple of weeks ago, but I didn't get to posting it until now, as I hadn't gotten the pictures organized yet.

I did! :D - In all of the 60 or so minutes it took me. Most of that went towards making the wooden thumb screws for the CPU HS. Otherwise, the OS install went pretty quickly to... Windows 7 Pro, by...

Talking my E-VGA 780i-SLI PC "build"

New year and time for new PC builds, right? :)

Well, okay, this build isn’t exactly “new” stuff, nor did I start it this year. Rather, some of its parts have been waiting on my shelf since...

No offense, but I think you have a comprehension problem, my friend. :p:

Re: resistance burned adp 240 ar power supply ps4

Re: xbox one-s

Nope, not me. But given the hardware... particularly the GPU - an AMD HD7770 variant, I'd expect the GPU VRM and RAM VRM sections to read similar resistance to a discreet HD7770 GPU. Just a guess,...

Re: Sony Audio System Shake 7 Went dead after thunderstorm

Start with the power supply. Does the stand-by section output the proper voltage? If yes, can you turn-on the main PSU without the amp being connected? If not, does the APFC try to run when you turn...

Re: Definitive Technology BP7006 AMP Guide Help

Re: Apple ][+ Astec power supply

It's an Astec PSU. They generally use very reliable parts... save for those RIFA film caps. :lol:
But once you get those taken care of (and maybe the output caps too, as PeteS mentioned)... the PSU...
