611483 power supply

[crazzycol]

Hi all

just a quick question, sometime ago i had a power up issue with my HP 8300 CMT, at the time power supply's were a ridiculous amount to replace and the 2nd hand market there was very few, so i opted to for a modular power supply with an adaptor. all was going fine for the last 4 years, then the power supply went PUFF, so ive replaced it with the correct 611483 model, but it now doesnt boot not even to bios, i was wondering are all 611483 power supply's the same?? does the old 6 pin connector differ in anyway?? unfortunately the old psu has long been binned and i cant use it as a reference, ive got a 4 wired 6 pin and all it does is bleep 4 times and then ramp up the psu fan, doesnt boot, nothing on screen, ive seen one of these 6 pin connectors had 5 wires in, should i just say f*ck it and go back to the ATX power supply? or has my  motherboard croaked it ??  thanks in advance for you answers

@crazzycol -- all it does is bleep 4 times and then ramp up the psu fan, doesnt boot, nothing on screen

When you power-on a computer, it launches the POST (Power On Self Test).

Part of the POST is to run the fan(s) at 100% speed, and noise.

If the POST is successful, and the temperature of the motherboard and processor are "normal", then the motherboard should tell the fan(s) to slow-down (and get quiet).

If the POST "fails", one symptom is the noise of the fan(s).

has my motherboard croaked it ?? 

Very possibly.

Possibly, I have even more bad news for you. 

See: Windows processor requirements Windows 11 supported Intel processors | Microsoft Docs

to determine if your processor will be compatible with Windows 11.

If not, then anything you build will have a "sunset" after October 2025.

Sigh.
