And if the group regulation hasn't been tuned properly for 5V heavy applications, you get what you are seeing with the 12V shooting up as the PSU inadvertently adds more energy to the 12V circuit at the same time to delivering more energy to keep the 5V rail propped up. So just get something from a …

Just as a bit of a tangent, I thought FSP was generally well regarded. Did I get that wrong, or does it vary between models? My personal impression is that FSP is best regarded by people who did not do test bench examinations. I originally considered FSP an acceptable brand until I did my tests . …

Ugh that looks like FSP :vomit: No filter and fan of the cheapest sort. That is not what I like or even would consider using myself. Asides of that, just the current draw of the inactive HDD of maybe 1/3 to 1/2A on 12V probably doesn't constitute a sufficient load for this PSU. You need something …

Could you provide more details of the PSU? Type name and some amps it should be able to provide per power rail? Some rebrands use the builders type name (like a HP or Dell branded pus with FSP type name) Maybe you could open one up and take a picture from the inside? That way we can help telling …

I don't think those Athena AT units are very good, at least from what I've heard, so pictures of the inside would definitely help. The Startech ones, on the other hand are quite reliable... the protection on those saved me from an incorrectly plugged P8/P9 connector the other day. Another reason …

Yep, bad design or faulty. I personally don't trust any power supplies except ones from very reputable companies like Seasonic. For AT systems, I use an ATX to AT adapter. Hi, thanks for the response! That would be a great solution and I would feel more comfortable running a modern, quality power …

Hello, I'm hoping to seek some advice from some power supply experts. Super short story is that I'm seeing 13V on my 12V line with 2 brand new AT power supplies, and the voltage increases under load. Slightly longer story... I'm building out a retro PC with an ASUS P5A-B, K6-2 500Mhz, S3 Trio64V+, …

Thank you Sarah Walker for your great contributions over the years in creating and enhancing PCem. I feel terribly for the manner in which people have apparently treated and disrespected you. All too often on the internet, the vocal minority have too loud a voice. You are a gifted and talented woman …
