    Default Delta DPS-600MB 13 year redux

    Well, I've been inactive here (and everywhere online really) for a number of years now. With a new job and a ton of things on my plate, it's a rare event that I can find time to post nowadays. I do still occasionally lurk around and read some of the reviews though. Anyhow, I read a few of the 10 year redux reviews over the last little while at HardOCP, which kinda got me thinking - The Delta DPS-600MB in my main PC was originally sold back in 05, making it 13 years old now. I recently had to replace it in order to make way for a new GTX1070, as it doesn't have the two required 8 pin connectors. So, I decided to dig out the load tester after quiet-ish stretch at work and load it up. Here's how it went:

    3.3V - 14.26A Load - 3.32V - 12.6mv ripple

    5V - 15A Load* - 5.02V - 24.8mV ripple

    12V - 44.08A Load - 11.76V - 36.4mV ripple

    5VSB - 2A Load* - 5.01V - 12.8mV Ripple

    -12V - 0.2A Load - 12.16V - 10.8mV Ripple

    * Approximate load only. Ammeters on these rails were not functioning

    In total, that's about 653.5W load. AC power draw was 824W, so that's about 79% efficiency. Not amazing by today's standards, but not terrible either for a non-80plus power supply.

    In short, this thing is showing no signs of distress, and even handled a 50W overload, despite being 13 years old. At this rate, it will still be going strong after 20 years in service. I knew there was a good reason why Delta has long been my favorite OEM.

    Damn, those are some good results. Do you happen to know what topology it uses on the secondary side? That's a fairly balanced load, so a group regulation scheme would perform well there, though it could also use Indy regulation...

    I have a DPS-470-AB I've been meaning to pull apart for a while, I've just not had time lately though (it's a dual PCB design so I can't see anything from the back of the PSU)

    It's individually regulated. There is a Russian forum here (https://forum.radeon.ru/viewtopic.php?t=13951) with some inside pictures of a DPS-600MB (links are in the first post)

    Thanks for checking up on this! Such tests are not common but very helpful.

    Thanks! From what I can see, that looks similar to the limited part of the DPS470AB that I can see, though the 470 has a vertical bulk cap, not horizontal...

    I'd love to see more of these, but finding PCs that have been in use for 10+ years is hard (I have access to a bunch of ex-business ones, but I don't own a load tester, nor an oscilloscope and my DMM is far from accurate enough for this kind of work).

    Dual PCB unit with 80mm Fan, what else?

    Is this the Plattform the Antec Signature was based on?
