Question about Antec Phantom 500 (PHANTOM500) 500-Watt Power Supply

1 Answer

Antec Phantom 500 burned out

... due to some overvoltage / surge on AC mains. We opened the PS and found nothing visibly burnt/ charred / blown. Are checking the input ckt upto CX1 CX2 (X capacitors?) and so far havent found any problem. Any ideas on which component may have gone bad and how to check.

I have an Antec Truepower 2.0 TPII-430. This power supply provides power to the fans but when I push the computer power-up button, nothing happens. I installed another similar power supply and everything...

Test it. Unplug the molex connector from the mothrboard. You can use a wire or a paper clip to test it to power on. You will connect (short) pin 14 to and ground pin. (diagram here) For example, put one end of the paper clip into pin 14, and the other end into 13, 15, or 16. If the power supply turns on and fan running then maybe a problem with the front panel switch on the computer case.
P.S. make sure you unplug all other leads to drives before doing this.

Hi, I want to use the DC power supply disconnected from the motherboard. When all connectors to the powersupply are disconnected the fan in the power supply is not rotating and no 12 volt DC is...

As long as you're not talking about hooking it up to anything else, as in a hobby project, then the best thing to do is go out and get yourself a power supply tester. Office Depot still sells Antec ones in my city for under $20, and I recently bought one or two over eBay, direct from China, for under $4--shipping incl--each!
You just plug the tester up to the PS, plug the PS into the wall outlet, turn it on, and ...there you go!
Just one word of warning--be careful with Bestec power supplies--nothing personal against the company itself, but they should all be replaced before they damage your computer. I never worked on any eMachine with one of these power supplies, which had a hardware-related problem, where there wasn't damage to the motherboard due to their Bestec power supplies. They are not properly 'fused' to protect your computer against spikes, surges, etc.

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.

Plugged computer back in after move and won't start. green light in mb on.

Actually, there is nothing you can do with the hard drive. If its shorting out the power supply when its pugged in then it is defective. However, most hard drives carry a 3 year warranty from the manufacture. If the drive is younger then 3 years old, I would call the manufacture and get it repaired or replace. Hope this helps . . .

(I have Antec Phantom 500) when I turn on my computer it turns on for about a split second and it goes off ..

Most likely the power supply but it could be the motherboard.

Do you see anything on the screen when it comes on?

Antec sp-500 power up?

Hi oldgunny, I think you would be better to shoot it befor opening it. The only serviceable part inside is a fuse and if this was blown then it would not start at all, so regretable as it may be you will need to replace it.
