Thread: DSATX 220W vs Custom built Mastero/Sproggy 4.5 (Review)

Tested again this morning.
Drove 35 min from home to work. Pulled in the parking lot and shut the car off. Walked around and double check the PSU's LED if blinking or not. Yup it was blinking. Hit the "User Switch" button, nada. Hit again couple times, and nada. Wait for a min then hit the power button, PC shutting down. Walked back to check the PSU. LED was blinking. Mobo's StandBy LED indicator was ON (meaning the PSU was on stand by). Waited a while, then PSU's LED and mobo's Standby LED was off (meaning PSU cut off power.)
Jeff 1 suggestion. If you can, make the 5V rail a little more powerfull. 15A maybe? Compare between 5V rail and 12V, the 5V rail is definitely weak. Regulating 5V is much easier (I think) than 12V right? There is plenty of power on 12V but not so much on 5V.
One of my AC PSU has 5A on 3.3V, 18A on 5V, and 4.5A on 12V. This PSU runs my setup perfect. And that is why I custom built my Sproggy as close to that output as possible.

greenman100 That is the reason I put a note there. However, the POL 5V and 12V were built into the Sproggy board. I called it POL because those 2 rails didn't joint together with the 20 pins ATX cable. I can't check those with the DSATX, unless I had to build one.

Well this is why we have the beta test. Actually the documentation is wrong. It works just fine it is just the wrong pin!!!!!

USER_SW should be on D, SL_SEN should be on E!!! I'll update this drawing soon.

Wait a sec, how do you know the 5V is weak? If the 5 volt rail falls outside of the 7% range, the DSATX will just shutdown completly, everything will turn off until you cycle ACC. Is that happening or is stuff just "freezing"? There might be something else going on here..


The DSATX is primarly designed for newer motherboards that have the P4 12V connector. This allows the motherboard to split the Main Power Loading between the 5V and 12V. Your motherboard uses the +5 volts to power the CPU along with everything else. You're hardly using the +12 volts at all. I'll look into getting a little more juice out of the 5 volts, but for now, could you try underclocking your CPU a bit to see if that solved the problem?

-Jeff

Let see what I can do about the 5V in my case, but that won't happen for a while.
So far I am okay with it cuz I don't always watch DVD on Disc. I'll try to power the DVD drive separately to see if the freezing still happen.

Now if you guys using this "USER_SW" option, double check the documentation/usermanual again. After making change per Jeff's new instruction, it works like a charm.
ACC off, Press button to short USER_SW, PC goes shutdown/hibernate, PC off, couple seconds (2 or 3) later, power off.
