Re: Enermax EG465AX-VE(G) Thermistor

The original supply had the 20 pin. Yep, the newer one has the 24 pin (20+4; they are separate) connector.

The actual draw on the 3.3V rail was not measured. It might be easier to use a DC-DC converter that can handle the current but we cannot modify the OEM's design. We have to keep everything working and intact according to OEM documentation and specs.

Luckily, the tech was able to transfer the wire harness to the newer supply and get the PC back up and running!

Re: Enermax EG465AX-VE(G) Thermistor

Sorry for the delayed response I was out of town. I will follow up with the tech and get more info. I do remember that the PSU had capability to do 40A on the 3.3V rail and 46A on the 5V. This is different from the standard EG651P-VE. I'm assuming this is for the backprojector board.

The modification involves a separate wire harness with decently heavy DC wires running to a capacitor bank before connecting to the backprojector board. Other than that, I will let you know if there's anything different on the PCB.

Re: Enermax EG465AX-VE(G) Thermistor

It's just a tricky situation. Basically we found the supply of the same part number and are getting a couple overnighted. If the PSU is identical except for the mods commissioned by the OEM, we will attempt to repair the old one first. If for any reason we can't do that, we will have to modify one of the new supplies or have a third-party do so. We have been trying to locate an entire PC that it could be harvested from, but to no avail as of yet.

Thanks again for your help!

Re: Enermax EG465AX-VE(G) Thermistor



I really appreciate your responses! Thanks. Sorry, he just gave me the specifics. A capacitor was damaged but did not disintegrate - it was a 1200uF aluminum electrolytic. An MOV and a power resistor disintegrated....

Re: Enermax EG465AX-VE(G) Thermistor



Oh, ok. The system is an international mode and usually takes 230V and to test and work on it on the bench switched the supply to 115V setting. He unfortunately forgot to switch the setting back to 230V on the supply when finished and it was sent to the site like that. The result was that it did take out the varistor, a capacitor and a power resistor. The varistor and capacitor disintegrated beyond recognition and I don't know the exact specs on them. I can infer, given common designs etc but for medical-related equipment, we need...

Re: Enermax EG465AX-VE(G) Thermistor



Yes, exactly. The supply was set to 115V setting and connected to 230V. The partial schematic you posted above resembles the PCB of the PSU I'm working on. Do you by any chance have the full schematic for that model? That would be helpful. Thanks!...

Re: Enermax EG465AX-VE(G) Thermistor

Hello!

I have a PSU for a medical PC that's a modded Enermax EG651P-VE. Basically someone forgot to switch the transformer setting to 230V and it blew multiple components. The supply is custom and impossible to find a replacement for. If anyone has a schematic for it or a similar PSU, I would be seriously grateful!

Thanks.
