Hi there folks I'm planning on buying/building my new PC over the next four weeks, so i've already bought the Case and PSU now I havent bought the other items yet but i wanted to check that the case and psu work. Now i've installed the psu but when I turn it on nothing happens, is it broken? Or do I have to have it connected to a mainboard etc... for it to work?
you can test the PSU by connecting some hdd / dvd / cd drives / fans then "jump start" the PSU by simulating the "power_on" motherboard signal by shunting the "PS_ON" green wire to ground via a paper clip or something - then plugging the unit in and powering the rear switch on...
Here is an example of the atx jumper:
It should fire up the PSU and stay on, the drives should be spinning and the cd/dvd should be able to eject. You *have* to have at least one hdd or cd/dvd drive connected to act as a "pull-up" load to power the unit on. The drives should spin up and the cd tray should be ejectable and it should stay on. If you have a voltmeter you can test voltages, but they may be out-of-spec some PSUs are like that in a low-load or no-load scenario
Thanks for the quick reply! I was just worried the thing didnt work but from what you said i guess it wont turn on unless its connected to a motherboard?
Ok Newb question # two the PSU came with plastic ties around the wires near the actual box one going through the actual box and one next to it around the cables. I removed the black twist ties but i dont know if i should remove the ones next to the PSU box?
Hehe I know this must be a silly question to you veterans out there but im learning!
lol we were all noobs once... yea the mobo acts as the middle-man between the power-on switch on the case and the psu itself, no harm in fooling it as long as it's done correctly. Nice PSU by the way 8)
You can leave the twist-ties on if you like to help out with the cable organizing, but some use a metal insert like a garbage tie and for some reason I am paranoid of keeping those around since it is possible for the metal to wear out from constant twisting and may break off and cause a short on the mobo or worse a bottom-mounted psu 8O
I removed all the black twist ties but theres still those 2 white ones near and going into the PSU I guess they are supporting the wires but they're hard plastic. Plastic + electricity + Heat = Hmm should i be leaving them there?
Again thanks for the advice and quick reply i appreciate it!
No prob, as long as they are not restricting the length of the cable no harm done... If they are the zip-ties immediately after the cables exit the psu housing then yes they are for support so best leave them.
Will do, now the hard part.... waiting! Looking forward to the build but from reading the forums i need alot more tools, there was me thinking i'd be ok with a phillips screwdriver! LOL.
Do i really need things like a static band? etc...
Thanks for your patience doolittle. Choosing parts, worrying about compatability issues etc.... can get a little over whelming to those of us just starting out
Doolittle, your post on the PSU testing was very impressive. I am so happy you posted that. Been in the business for over 35 yrs (mostly on the software end) and never heard of this method. Sure is going to save me a lot of grief on Thursday when I go to troubleshoot one of the pc's I built couple year ago.
Thank you very much. I am so glad I subscribed to these forum.
