    It looks to be the same size as the Opus 90w and almost the same price. Nice!

    So where is 220W version for the price of 150W?

      I dunno but I like the small footprint, fanless, power supplies that run cool and quiet.

        So I get it you're driving a golf cart?

          The OPUS 90 watt has been discontinued, it is no longer being manufactured. The OPUS 120 watt is the replacement.

            Nice. Wanna take my 90w in on trade!?

            By the way, fix the 120w link on the 90w page. It's a 404.

              So compared to the M1-ATX, the new Opus 120W offers an extra 1.5A on the 12V rail and 2A less on the 5V and 3.3V rails. The listing didn't mention any dependencies between the rails. It also doesn't mention if the firmware is user flashable or not though presumably the firmware is the same (or similar) the tried and mostly trouble free Opus 150W firmware. Another big concern will be the standby power issue. Can it be jumper selected to disable the +5VSB rail like the Opus 90W (and unlike the Opus 150W)?

                PSU's have flashable firmware now? I just want the extra 30w to handle the load of my system. I haven't built my system yet, although I have 95% of the parts. I'm scared to see if my 90w is up to the challenge of all these USB devices. I have about 7 that need to run simultaneously. I MAY put 2 or 3 of them on an external-powered hub but I doubt it because I'd have to run the 5v off the PSU anyway!

                  It's not user flashable.

                  Standby power is disabled by default on the 120 watt. There is a jumper to enable if if you want to.

                    I dont think USB devices ask that much amount of wattage. Because its 5v with max 0.5a (without external power ofcourse), which makes it 2.5 watt. 7 devices makes it 17.5watt all running on their max.
                    Am i wrong on this?

                      No, but some USB devices use external power because they exceed (or far exceed) 2.5W maximum provided by the bus.

                      Yes, some do.

                      Just because a PSU is rated 120W versus 90W doesn't mean you have an extra 30W to play with for any particular purpose. With respect to 5V power, it is a more capable supply than the previous 90W model and about 20% LESS CAPABLE than the 90W rated M1-ATX and the Opus 150W; each of which supply 10A on the 5V rail.

                          Wait, so what are you saying?

                            It wasn't clear?

                            For USB devices (i.e. considering the 5V requirements only) you would rank the fully regulated ATX DC-DC PSUs in this order.

                            Opus 90W - 6A
                            Opus 80W - 8A
                            Opus 120W - 8A
                            M1-ATX 90W - 10A *(reduced with concurrent 12V consumption)
                            Opus 150W - 10A

                            At $90, I'd say the new 80W Opus is even more interesting than the 120W. It also appears to be the right shape and size to replace the Morex unregulated supplies.

                              Ohh now I see what you are saying. Sorry I'm an electrician noob (thanks to this forum . Why the hell didn't they up the 5v amps for the 120w ?? What rail is the extra power on? I think that sucks. I feel that USB peripherals are very important to a mobile computer... and if that's what these things are designed for, then they are falling short.
