Re: Help me find a replacement power supply!

It looks similar to TFX, but seems taller (almost looks like they took a standard-ATX PCB and turned it sideways and slapped the fan on top). It might be some now dead proprietary form-factor that...

Re: WD drive "colors"

Not so much any more (note my previous post). I work for a company that measures network storage in petabytes and it was all migrated to SSD about two years ago now (and to think, less than a decade...

Re: WD drive "colors"

At work our data center went to all SSD several years ago, and since a lot of what we do involves data/databases there have been significant performance improvements. There is the issue of failure,...

Re: The Cheapest ATX Power Supply on Amazon Prime, How bad can it be?

The load amounts (amps) are listed in each post.

For the actual hardware used in the most recent test a Kunkin KL283 (https://www.badcaps.net/forum/showthread.php?t=86168)300W 30A (15A X2)...

Re: The Cheapest ATX Power Supply on Amazon Prime, How bad can it be?

Some of it is due to shutter lag, I tried turning down the intensity (it was all the way up on the first set of pics) on the scope a little on the second set of pics (with the 350W load) to try and...

Re: The Cheapest ATX Power Supply on Amazon Prime, How bad can it be?

Since I finally have a big enough electronic load to put 30A on the 12V rail lets see if this PSU can handle it, I put 6A on the 5V rail and 4A on the 3.3V to better represent a modern system for a...

Re: $20 "500W" PSU From MicroCenter, how bad can it be?

Re: Kunkin KL283 300W (150W X2) electronic load

Looks like the same basic design, but on the KP184 you get a more advanced control panel and I/O ports (and of course higher wattage rating as the KL284 would be the 400W dual channel version), but...

Re: $20 "500W" PSU From MicroCenter, how bad can it be?

Yah, makes it hard to tell if they're fakes or just really faded/dirty with some of the text rubbed off from age. Either way they are either salvaged caps or phony, not good to find in a new PSU.

Re: $20 "500W" PSU From MicroCenter, how bad can it be?

Re: $20 "500W" PSU From MicroCenter, how bad can it be?

Yah, MicroCenter hasn't really made its way to PA yet (with the exception of one location in the Philadelphia area) so for me it means a trip to Northern MD. (which is closer to me than Philly).

Re: $20 "500W" PSU From MicroCenter, how bad can it be?

^This, between the thin wires from the mains connector to the PCB and those tiny little "bridge rectifier" diodes it is unlikely that this thing would be able to pull much current for very long.

Re: Could all new PC motherboards only require a primary 12V rail?

Many OEMs are doing that now. Dell, HP, and Lenovo have all been doing it for several years now (and of course all with their own proprietary connectors that aren't compatible with each other).

Re: $20 "500W" PSU From MicroCenter, how bad can it be?

It couldn't even do the lower 137W in spec (granted that is an ancient PSU tester so it was very 3.3V/5V heavy, but that is also an ancient PSU design so it should actually handle that better than a...
