Question about Antec 650W EarthWatts ATX Power Supply 80 PLUS certified ATX Case

1 Answer

I replaced my power supply with a new Antec 650

Hi my name is Ben I am not a computer expert but I know enough to get myself in to trouble. Having said that, I replaced my old power supply with a new Antec 650 watts power supply. Computer is booting up and running fine and it is quieter too. However, when I press delete to get to the BIOS setup utility at boot up it will go there and displays everything. Once I enter the password and press enter key everything disappears. I will get only two choices, which are MAIN AND EXIT. If I press F1 this displays: ''Setup changes system behavior by modifying the power on initialization parameters''...... If any one can help it would be very nice and I thank you.

P.S. After installing this power supply, I forgot to make sure to turn the PSU switch to the ON position (I) before booting up the PC for the first time as the manual had stated. Thanks

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.
May be it can help you.

Hi, in Antec 300watt power supply there is 3 cables or input or current 220volt. The cables are Black, Green and white. Which one is earth, which on is live(positive) and which one is negative?


For 120 volt operation use
black for the hot, White for the natural, Green for earth ground.
For 240 volt operation use;

Black and White for the 240 volt and Green for earth ground.
Black is generally designated as the "Hot" or "positive" .
You must make sure the switch on the power supply is set for the voltage you are using. ie: 120/240

I give up! Why would you need a schematic for a computer power supply? I've been in the computer business for over 30 years and have never needed a power supply schematic. Just curious!

Where can I find power supply for HP model ATX300-12ZBD


There are lots of ATX power supplies on the market. You do not need to use a HP 300 watt power supply. Just purchase one that suit your requirements - 300 watt or more. These power supplies have standard mounting holes.

Thoughts: There are two connections from the power supply to the motherboard. One has 24 pins and the other has 4. Make sure they both are correctly (and fully) inserted.
Try powering the computer on with all the devices disconnected (hard drive, CD, etc).

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.

Take your desktop computer (and the dead power-supply) to any computer-store. They can sell you a "generic" power-supply that will be compatible with your original power-supply.

Hint: the smaller the computer-store that you go to, namely a "mom-and-pop" company, the more-likely that they will install it for free, if you buy the new power-supply from them.

Gateway PC into Antec enclosure?


Hi:
You should be able to transfer your motherboard to the new case, but some things to check before you do:
How do the power switches and front audio/USB connections work for the old gateway? Are they standard or vendor specific? Are the optical drives in the gateway standard, or do they have special fronts on them? I have done what you are wanting to do several times, and often you need to replace OEM optical drives, and sometimes the motherboard headers don't match up with a builder case, so you do the best you can.
