See your cpu fan connector, weather it is connected properly. to check wether psu is working properly, short the black n green wires present in the psu's mother board connetor by using a single strand wire, and switch on. if the fan rotates there is no probs with the the psu. then u will have to replace the motherboard

Cooler Master 1000w Silent Pro M not compatible with MSI MS-7548 (Aspen) motherboard?

So you're using the same CPU 4+4 Pin x2 power cable on both rigs?
(One of them)

Yes, I see it's a modular cable design, and the CPU 4+4 Pin x2 power cable, can be used as a single 4-pin ATX +12 Volt power cable,

http://www.playtool.com/pages/psuconnectors/connectors.html#eps4plus4

ALL Yellow wires are 12 Volt (DC) wires.
ALL Black wires are Ground wires.

ALL 12 Volt wires go to ONE single 12 Volt power rail, in the Power Supply, BUT; there is nothing saying an individual Yellow wire may be bad.
This is why I wondered if you are using the SAME power cable CONNECTOR. Same power cable.

Yes?
Then suggest it has something to do with the Active PFC circuit.

http://www.hardwaresecrets.com/article/Anatomy-of-Switching-Power-Supplies/327/6

Not aware of any setting to change in BIOS Setup utility - Power.

BUT, I do not know everything! lol!

IMHO there is no reason it will not work, unless as said; something to do with the Active PFC circuit.

From here let's hope someone who really knows what is going on, will post.

My pc is shutting down and I can't wake it up without shutting down the power from power supply. The Antec 300 tower has two blue lights- the top light starts blinking when it has shut down and I


sounds like a power supply problem

Test your PSU power supply unit or replace it if your power supply units fan is not working your PSU is faulty

http://pcsupport.about.com/od/toolsofthetrade/f/powersupplytest.htm



One bad lead can cause a computer to continue on a cycle of restarting or to shutdown or fail to detect/ boot up a computer hard drive



Test all leads that attach to your hard drive power and data cables IDE SATA
the leads from your MOTHERBOARD TO YOUR HARD DRIVE make sure they have a secure dust free connections and are not faulty or just replace them they could be faulty

hope this helps

Computer will not start. No fans, hard drive or monitor motion at all. But, a green light on my motherboard blinks.


Out university has hhad a failure rate on antec 450w psu of 40-50% over 4 years (total number of pc:s with this psu was approx. 300). Check your motherboard with a known-to-be-good power supply.

Turn on the computer nothing happen then smell burning from the power supply! turned off right away.


That power supply is probably dead. try your motherboard witha known-to-be-good power supply to determine if your system has survived. IN my experience the failrate for antec sp450 watt psu is close to 40% over 4 years (300 pc:s at university), so there is a high probability that your psu is unrecoverable.

Cooling fan for antec power supply pp 303xp does not come on when computer is switched on. Is this a replaceable item or do I have to buy a new power supply?


I THINK I REMEMBER reading that Antec had introduced a feature on some of their psu s where essentially the fan(s) were thermally controlled - if the psu was not working very hard it remained cool and the fan remained off but as the psu got warm with additional load it gradually increased fan speed. Perhaps this the issue you are seeing and nothing is wrong ?
PSU's are generally difficult to open and contain few accessible parts. some you can actually change the fan. I don't know about yours though.

I agree with you about the power supply being faulty. Unfortunately FixYa is not affiliated with Antec nor sells or service any computer components.
You need to contact the supplier who sold you the power supply or contact Antec.

I replaced my power supply with a new Antec 650


Let give it a try.
Turn off your computer and unplug it from main supply. Remove the battery for cmos bios. wait half an hour. insert battery again and reset the cmos through jumpers. Plug the main supply and start your computer.

Psu shut down


99% TIME IT IS A FAULTY FAN GOING OUT.

REPLACING THE FAN INSIDE THE POWER SUPPLY WILL RESOLVE THE PROBLEM.

P/S ARE CHEAP, JUST BUY A NEW ONE OOR REPLACE WITH ONE YOU HAVE ON HAND
