The PSU and console5 adapter for the SNES should also work with the Virtual Boy, yes?

Correct, I planned on adding more to the list as I have time. That's one I'll add right now.

Great info, bookmarked for when I need one. I'm actually still using all original for NESRGB, SNES, Genesis Model 1, and TG16 - no problems as of yet.

Seems like most are $15 too (Genesis M1 is $25 for some reason) which isn't a bad price at all.

It's because I selected the 3.5A model. The reason for this is you can either use it straight, or set it up to use as a single brick for the "Tower of Power" (with the listed adapters/splitters). If you don't intend to do that, you can always downgrade to the cheaper 2A version.

Thanks a lot for this post, I'm ordering for my nes, snes, genesis and pc engine.

What do you recomend for consoles with internal PSU (saturn, dreamcast, PS2, Wii....)???? I need to use coverters on mines from 220V to 120V, but they get really warm and some make an anoying high pitch sound.

For those, I recommend looking at mod solutions, although they can be hit & miss. I ordered a DreamPSU a few months ago, but it's looking very unlikely I'll ever get it or my money back. It's a shame too because the design is exactly what I'm looking for with extra fan sockets.

I've considered getting something more modern for some of my systems, but Tokyo outlets use 50hz instead of 60hz (also 100v instead of 120v, but the PSUs you list seem to accept a wide range). Any idea? There's plenty of 3rd party adapters sold in Japan, but not sure how well they perform.

One nice thing about the original Japanese versions of retro consoles is that the FC, SFC, white PCE+Core Grafx+Core Grafx II, MD, MCD, and even Virtual Boy (and probably some others, but IIRC not the Disk System, various PCE CD systems or Super Grafx) all use the same size center-negative post on their AC adapters, although I think the MD and MCD require a bit more power.

It's kind of hard to find info on specific ratings even when searching in Japanese, but here's a Japanese page that lists some details on PCE adapters: http://meganemushi.blog.fc2.com/blog-entry-173.html

These are switching power supplies I assume. I'd rather stick with my original bricks. Switchers can introduce unwanted noise in systems that weren't originally designed to take them.

Change out the single smoothing capacitor in your original bricks, and you're good to go for another 30 years.

And yet they don't introduce noise. I've done both video and audio comparisons between original bricks and these triads and there is NO increase of noise of any type that can be heard or seen.

Besides, the main point of these are to replace missing PSUs. For example, I got my AES for pretty cheap because it was missing the PSU. I bought a Triad for it and it has worked perfectly. I now use Triads on most all of my other consoles too. I'm a hawk for noise, so you can bet I would have noticed it.

I'm not talking about visible noise in the picture or sound. I meant noise on data lines, CPU lines and such. Have you taken an oscilloscope to your consoles to measure for noise? Switchers can put unwanted stress on your CPU and any other chips in the system, since the system wasn't designed around a switching supply in the first place. Yeah it may work with no noticeable noise on your CRT, but there's always a chance that the life of your console will be reduced. Since your consoles are already basically antiques as it is, why risk it? Just hunt down an original brick on ebay.

You can't just blanket-dismiss switching power supplies as being 'bad' for your retro consoles. For example, HD Retrovision recommends this one:

https://www.amazon.com/dp/B001BRKFII

Now due to the size, there's no way in hell that is a linear power supply. Now factor in the cost and compare to Triads, which cost more money and are distributed on electronics dealer web sites. I seriously doubt the Amazon offering is going to outperform a dedicated Triad. Neverthless you technically 'could' be right in that maybe Triads aren't as clean as the PWR+ PSU on Amazon, so I'll do some actual scope tests between the two to find out how they stack up.

All I can tell you right now, is I've actually heard of people getting a CLEANER picture from their NESRGB modded NES console using a Triad over an OEM brick. I know that's concerning video output and not what you're talking about, but it still says something when it can resolve video noise issues where the OEM brick couldn't.

Oh and for the record, I check for video noise on an OSSC with an E1S capture card, which is far more sensitive than a CRT. For example, this image was captured from a Triad-powered AES console:

I wouldn't consider HD retrovision an authority on electrical engineering. Sorry, but they're just a few guys that made a cheap RGB to component cable for the masses.

You need to do scope tests comparing OEM bricks to either the triad or the other one you linked to on Amazon. And make sure the OEM is freshly recapped for a fair comparison.

That NESRGB case study you mentioned could be simply because of the fact that they switched from AC to DC input with their new PSU, despite being a switcher. The caps are probably old and worn out on the NES's AC to DC rectification circuit. Switching to DC input could've helped clean up the picture in their case. If they were to try an original Famicom or Sega Genesis model 1 brick on their NES, it would probably have the same results.

good quality modern SMPS designs will provide smoother power than a basic ass barebones unregulated transformer/rectifier supply design (which is exactly what the OEM bricks were)

So I think a good solution for my consoles with internal PSU is conect them all of them to one of this:

https://www.digikey.com/product-detail/ ... =289564183

It says it is for medical aplication so I think is good quality (it's also the same brand FBX likes).

Do you think it'll be fine???

Also, the jp and usa consoles say to work with 120V @ 60hz, but I've been using a cheap converter and feed them 120V @ 50hz and never experienced any trouble (my country is 220V@50hz). Does frequency matter??

Ste is actually one of the most brilliant electrical engineers I've ever met. It pains me when people dismiss him without even reviewing his credentials & career. Just because they make cables doesn't make them hacks or amateurs. Here's what Ste had to say when I asked him about your concerns:
Is his contention that Sega/Nintendo/Sony would've used switching supplies back in the day if it wasn't harmful? If so, it's rather ignorant of the history of power supply technology and all the advancements that have been made. It's one of the fastest moving fields of electronics, and is why LED lighting even exists nowadays. The biggest advancements have been in the area of MOSFETs, which are now so crazy efficient you're seeing Rds(ON) in the single digits of milliohms. That's several order of magnitudes less than 2 decades ago and why BJTs were used back then instead. 32X for example used a switching supply w/ BJT internally for its +5V. Am I unaware of a large amount of 32X's blowing up mysteriously?

The only possible thing I can think of is ripple current being part of the equation of aluminum electrolytic capacitor life. However, it's a small contribution relative to ambient temperature, and a good switching supply has extremely low ripple on its output so a very minimal amount would actually hit the console's internal capacitors. I've never heard of power supply ripple damaging semiconductors. Most semiconductors have a PSRR (power supply rejection ratio), which is its ability to be immune to power supply noise across various frequencies. But that's getting into performance and has nothing to do with life-span. Anyway, if this person wants to argue their position I would say the burden of proof rests on their shoulders. Therefore, you should not get into any argument and simply ask for evidence to justify their claim and leave it at that.
Ste went on to give me details on how to set up a testing rig with the scope and a beefy 10 Ohm resistor (https://www.digikey.com/product-detail/ ... ND/3886586). His recommendation is anything 500mV and under is perfectly fine. However, looking up the datasheet for a Triad 9V 2A PSU, I found the ripple and noise MAXIMUM was already listed at 150mV pk-pk. So there's your answer. It falls well under the safe range.

Just checked the psu needed for an Atari 2600. The original outputs 9V and 500mA (center positive). This would be the Triad replacement:


North America 9V 2A, Center-Positive:https://www.digikey.com/product-detail/ ... ND/3094951

International 9V 2.5A, Center-Positive:https://www.digikey.com/product-detail/ ... ND/6165634

The 2600 has a 3.5 jack for power, Console5 sells this adapter:https://console5.com/store/dc-power-ada ... plugs.html

Here are some alternate links for the items needed for the genesis tower of power. Digikey/Arrow has the adapter/splitters. The reverse polarity jumper was also out of stock, so I used something available on console5.com (be sure you get the SNES adapter there too)

Just wanted to say thanks for this thread and add a small contribution. I haven't had any performance issues with the power adapter I got when I ordered my OSSC but I always thought the power supply itself felt cheap so I looked for a proper alternative.

With the correct type of barrel plug adapter, this could be used for USB devices as it outputs 5V

Anyone familiar with this 5V 10A PSU https://www.digikey.com/product-detail/ ... ND/5774322

Or this 5V 6A PSU https://www.digikey.com/product-detail/ ... ND/7703573

With a splitter it could power multiple devices. I'd love to have something that could power my Scart switch, OSSC, and HDMI switch in one go. It would be even better if I could add more devices like the Super NT and Mega SG. Unfortunately, the Triads seem to only go up to 5V 4A.

If you do that you will definitely introduce noise, even if you go the whole hog and get a linear PSU.

I too got tired of random picture noise and cheap replacement power bricks and I've been using one of these with the bulk of my retro consoles:-

https://www.ebay.co.uk/itm/2-Way-25W-25 ... 1975719251

Results have been fantastic, I spent a few hours playing NES last night and the noise I was seeing before using a Retro Game Supply adapter was totally gone. Given the noise was getting bad enough that I was going to send the machine away for re-capping and servicing it definitely shows how bad psus can spoil the picture quality.

You will definitely need the 25 watt version to run e.g Dreamcast (and a Pico PSU replacement) but older consoles don't draw much power at all.

I do use DC splitters with it to power multiple consoles but never at the same time, otherwise there's always picture noise.

I don't use this thing with the OSSC, OSSC was designed to use a switching power supply and is fine with that.

I would say given the extensive testing FBX did on the Triads that going full linear is probably dumb-audiophile levels of crazy but it's up to you. There will always be several consoles with weird adapters that won't work with this thing too.

Now that is really cool but probably too hardcore for me. However it did give me the idea to check diyaudio's store to see if they have anything power related. Lo and behold they recommend a Mean Well PSU of the same family that I linked to power their Amp Camp Amp. Tested and approved by Nelson Pass himself.

I've updated the OP to include Framemeister, OSSC, and gscartsw solutions. I added an extra amp on the USA version to 3 amps for the Framemeister (as I like to have some extra breathing room), and the International only has a 4 amp version available anyway.

Just curious here - whats is the reason using a splitter to power multiple devices could introduce noise? Are there any articles about this?
I have been using a splitter to power a Mega Drive/Mega-CD/32X combo with no issues, but thats understandable as they are all interconnected systems and share a common ground. However I have recently been toying with the idea of using a DC splitter to power both an AV Famicom and a Super Famicom to save plug sockets. Would this be a bad idea, and if so why?

The last thing I read about this (Might've been on VGP) is that a single PSU for multiple consoles shouldn't cause any interference so long as you're only running one console at a time; and that it's running multiple consoles simultaneously that's what causes issues, because they're not isolated from each other.

Thanks, I think I may have found the article you mentioned:-
https://www.videogameperfection.com/201 ... ene-dchub/
Odd that they had problems powering a Mega Drive/Mega CD combo :/

I guess I could try connecting an AV Famicom and Super Famicom with a DC splitter, since I wont ever be powering on both systems at the same time (Even though the power supply has more than enough amps to support both)

I wonder if it would be safe to power an OSSC, XRGB-Mini and gscartsw v5.2 with a 5V 4A power supply? In this case all three would be powered on at the same time, which I assume would increase the chance of issues.
