    Coolmax V-500 review @ Hardware Secrets (is this 2005???)

    http://www.hardwaresecrets.com/artic...-Review/1366/2

    Oh shit. AT-2005B... here's a platform i certainly have seen before... and no, it won't do 500W. Maybe half that. I actually have one badly burned example of it around here somewhere. You can see from the efficiency numbers that it already started to go south at 170W.

    JEE capacitors. You have to be kidding me. Do those even exist anymore? Maybe they're NOS... And Coolmax was brave enough to even put their name on the PCB... it coulda just said Deer.

      It was using 500W of power before it exploded.

      What did you expect from Coolmax?

        The engineer who designed that PCB in like 1997 is rolling in his grave somewhere in Taiwan.
        "We have offered them (the Arabs) a sensible way for so many years. But no, they wanted to fight. Fine! We gave them technology, the latest, the kind even Vietnam didn't have. They had double superiority in tanks and aircraft, triple in artillery, and in air defense and anti-tank weapons they had absolute supremacy. And what? Once again they were beaten. Once again they scrammed [sic]. Once again they screamed for us to come save them. Sadat woke me up in the middle of the night twice over the phone, 'Save me!' He demanded to send Soviet troops, and immediately! No! We are not going to fight for them."

          Might be a Deer clone since the controller is not ATX2005 as mentioned in the article but an AT2005B (datasheet https://cdn.badcaps-static.com/pdfs/...2fb8ab5167.pdf) which is not pin-compatible.

            I'm pretty sure it's a Sun Pro. They are about the only brand that use 'sapcon' caps.

            EDIT: It is definately a Sun Pro. I recently blew up a Sun Pro branded unit on the load tester and it had that same AT-2005B number in the exact same place on the PCB.

              I know it's not a Deer. But it's about the same quality.

                Yup. Sunpro safety series. They can actually come close to 400w output with the correct size transformer and primary switchers. Hardwaresecret's sister site has reviewed several that have blown up anywhere from 200 to 380w.

                  Anything will come close to 400W provided it's not built like a turd. It isn't the transformer nor primary switches which killed this one - it's that super lame 12v rectifier and those caps.

                    Considering that most Sun Pros explode below 400W, it's a wonder why they call it the safety series, since it's not technically safe for a PSU to explode. Me and shovenose both think they probably mean it's safe to assume it won't do what the label says.

                      I recently got one of these for free. It works, but I can definitely tell from the weight (or lack of it) that it won't do 500W.

                      Since I have no gaming needs and tend to run just one old 40GB hard drive and use onboard video, I might use it in a low value P4 system and store no data on it. Alternatively, I can use it as test power supply for when I get unknown working motherboards.

                      It is cloudy today so the photos aren't too great, but this board looks different from the review site.

                      And before you bash it too much, this one is working, while the other 4 Antecs I received recently all have bloated Fuhyjuu caps including one that has 11V DC on its 5V SB rail (killing an Intel 775 motherboard).

                        Yours is the same one that I got. Its made by a bit more competent small chinese OEM called LongYi.

                          Sun Pro Safety... yeah it's safe to assume it won't do what it says it will.
                          I had one of those (Raidmax "500W") blow up in my face once...when the computer wasn't even on. Lol.

                            the sun pro safety series I tested ages ago (a thermal master 420W) blew up twice. ( http://www.youtube.com/watch?v=wOjJOXIJNt4 )

                              @ retiredcaps: With proper output rectifiers (at least 80% efficiency) that looks meaty enough for 500W.

                              I just turned a former AT2005B platform into an unregulated +/-35v supply which will power a bi-amp setup with TDA7294s. Two bridges for the woofers and one stereo for the tweeters. A total of 6 ICs. Now i just need some more primary capacitance (it buzzes a little) and i'll be all fine.

                                The LongYi units have OPP (as do the sunpro safety series, but obviously that doesn't help much) but hopefully it is not set too high. If it's anything like mine was it is not beefy enough to do 500W, though it is silkscreened for two diode packs on the 12v and 5v rail.
