I was using the Triad WSU090-2000-R on an SNES today, and noticed some waviness in vertical lines. I changed over to the HDR-approved PWR+ supply, and the waviness was gone. I don't have an oscilloscope, but now I'm wondering if the Triad has some excess ripple.

That's really odd. I generally use the Triad's on anything with a Genesis 1-style plug, as there's no adapters needed. So far, I'm not getting any interference on all rev Genesis 1 consoles, Sega CD, Jaguar, Neo Geo...and I think at least one other. I've never used the Triad on SNES though, I stick with either original or PWR+ for those.

RetroRGB, would you be able to do oscilloscope readings of your Triads? Unless I missed it, it seems like no one has done this yet.

One mod I made to my SNES was to restore the big power-filtering cap that Nintendo normally left off, so my system should be pretty decent at smoothing power. But the Triad is still producing wavy vertical lines. I also compared with an original linear power supply just now, and confirmed no waviness with it either.

I decided to track down the "Power Pax" PSU datasheet for the OSSC and compared it to the Triad I listed. The Triad PSU cuts noise and ripple in HALF compared to the Power Pax PSU.

With regard to the SNES, I've not actually tried one on the SNES, but I seriously doubt the Amazon listing has better noise/ripple levels than the Triad version. Still though, this warrants further investigation for SNES consoles. I will say like retroRGB, I've not had a single issue with other consoles, and I've tested quite a few.

The WSX090-2500-R has been working fine for my SFC so far. Does reduced noise/ripple in the OSSC's PSU directly affect image quality?

Probably not since we're going from 200mV to 100mV. It's more a build quality satisfaction for the obsessive compulsive, and the brick part has a nice flat surface on top for custom labeling.


On a side note, PWR+ doesn't post datasheets, so I was unable to find out detailed specs. However, based on the price, I do not believe it is a better built PSU than the Triad.

What's the "Power Pax"? Is that the multi-region PSU that is sold together as an option with the OSSC on VideoGamePerfection or something?

Yeah that's the one.

So do you advise it to replace it with something better? If so would model/brand would be appropriate?

You don't really need to replace it until it dies. When that happens, just use the one I link to in the OP for the OSSC.

So there's no reason in getting a higher quality one like improvements to the picture?

You don't have to rely on a datasheet for the PWR+. HD Retrovision did their own direct oscilloscope testing on it, and the good results they got are the reason they recommend it. I've heard of no equivalent independent verification of the Triads.

Yes I already know this. However, even HD Retrovision will tell you that it's REALLY nice to have actual datasheet documentation from the manufacturer. As such, I want to know the max peak-to-peak ripple/noise rating of PWR+ adapters, and the company simply doesn't post those ratings as far as I can tell. On the Triads, you don't need to test them for ripple because the company already provides those ratings in the datasheet.

Updated the OP with more accurate information on AES console adapter requirements. There was a lot of bad information on the internet that got taken for granted as accurate, and after spending an hour doing more research on the subject, I was able to get a more clear idea of what needs to be looked out for. Even the Neo Geo Dev Wiki has harmful info on it. For example:

https://wiki.neogeodev.org/index.php?title=NEO-AES3-3_board

At the bottom of the web page, the site claims the 3-3 exclusively uses the 9V PSU. This is FALSE! My own 3-3 requires a 5V PSU, and using 9V as per that note would have fried my system.

Updated the OP to correct a mistake on the AES consoles that require 9V. I had 2.1mm barrel versions linked there, and just found out the PRO-POW3 uses 2.5mm barrels. I've updated the links, and my apologies for that mistake.

Re-corrected the 9V AC Adapter barrel size for AES consoles. I got two independent verifications that ALL AES consoles use 2.1mm center pins. So that's another fact straightened out. It's tough getting past all the assumed info from various experts to get to the truth, but I want to provide facts, not forum anecdotes.

Anyone have any quality power leads for SAT/PS1/PS2/DC etc? I know these are relatively simple 2 wires, but I'm looking to buy a decent quantity and want something well made and fairly priced.

OSSC was designed to work with switch mode power supplies and isn't super sensitive to noise so the Powerpax/Prime Power PSUs we use are a good match and represent good value for money.

I wouldn't sell anything I wouldn't use in my own setup and I stand by that.

That's good to know, does that PSU gets hot though if you leave it plugged in (well I of course turn off the OSSC when I don't use it, but AC Adapter continues to draw power even though unless you unhook them, no?)

Just checked, the OSSC PSU does get hot while in use, FBX do you know if the Triad replacement one gets hot while in use?

I'm looking for a replacement for a Kramer FC-14 power supply. My Kramer FC-49 power supply works in the FC-14 as well - that one is a Honor (brand) ADS-18D-12N 12015G model (I bought this new so I assume it's a high quality ps). Kramer manual says "12V DC Power Connector VDC, 80mA".

Looks just like this except for USA style plug. Has that weird collar on the barrel plug itself which can screw onto the Kramer - I don't think that's necessarily needed:

Image

I can measure the barrel if need be, but I don't think my micrometer will fit inside for those dimensions. Totally open to options cheaper than Triad if they'll be quality.
