Anyone remember auxiliary PSU's that fit into 5.25" drive bays?

I remember coming across these devices some 5 or 6 years ago. Has anyone ever used them or seen them? Are they still for sale? I don't remember the total Watts they were rated for but I seem to remember it was a couple of hundred Watts.

Found it. It was for Crossfire/SLI setups and is no longer available (it got rave reviews too):

Seems like you keep looking to the past to find solutions in the present. Just buy a new case my friend. :love:

Or maybe they just want to recall nostalgic techno oddity?

Yeah, I remember that thing. It is of course not very useful nowadays, since fewer and fewer cases even have 5'25 bays to begin with, also IIRC there were screaming fans inside...

It would have been a nice auxiliary PSU for a R9 295x2 or Titan-Z setup -- you wouldn't have to buy a new PSU. It might even have been useful for mining rigs.

I don't recall that particular one but I do remember seeing similar ones around 2007 -2009. They had several issues starting with cost being the same as a normal ATX unit and the efficiency of a DMV department on a holiday weekend with its computer system down. I think they were mostly aimed at people who owned mass produced desktops and were afraid of upgrading the PSU themselves but still wanted to install a dedicated video card.

I remember them but never used one. They were supposed to be for SLi, but I’m sure there were others. That was when 12v demands started to rise I think. Shortly after that regular PSUs started getting (a lot) more powerful.. and shortly after that I think 3.3 and 5v capacity started to dwindle.

I had the 650w Thermaltake dual-bay one for a while: https://www.newegg.com/thermaltake-w0158ru-650w/p/N82E16817153070?Item=N82E16817153070

It let me run 3 way SLI with 9800GTXs. But it quickly became more practical to just run one big PSU.

I still use it occasionally, even today, mainly for testing old GPU card or helping friends or family troubleshooting their GPU problem. a lot faster than replacing the PSU with bigger unit.

Yeppers, I happen to have one of them. It's a 250 watt unit made to help power a video card. :laugh:

Crazy how times have changed.

How do these auxiliary PSU's work? Do you have to use a separate switch to turn them on?

Yeah I got a good deal on a couple of VisionTek VT-450CD's. I never had a SLI setup but I used them to assist a couple of 500W power supplies when overclocking Xeons. IIRC they were around $25. each! Just found a couple of forum posts about the ePower 450W version of the APU from 2013 over at HardForums. HardOCP also did a review on it back then. The VisionTek "Juicebox" is the model that I used. It ran cool and quiet in my rigs. They were selling for $19. and I used mine until the i7 "Devils Canyon" was released. I upgraded to a pair of 650W XFX units in 2014. Absolutely NO regrets!

Nope, they fired up when I turned on the PC

Mine just had a splitter that attached to the 24-pin on the motherboard. The main PSU and aux PSU turned on at the same time thanks to the splitter.
