Solve : PSU problem?? |
|
Answer» Hello everyone. I tried doing the paper clip thing to try the PSU. I plugged a case fan to try it. It got power for half a second and then it stopped, again. You did the what now? Paper clip thing? Did you take ESD precautions? If so, describe them to me.I did that kind of test with the power supply: http://www.overclock.net/t/96712/how-to-jump-start-a-power-supply-psu-test-a-power-supply-and-components For the ESD precautions, everything was turned off, it was on a non-conductive surface, I was standing up, and I was grounded touching my computer case. Quote I was on a non-conductive surface Its conductivity that protects you from ESD (hence the reason you have to connect to your case in order to be protected) but you're not unfamiliar with the subject so I'll assume you didn't waste any hardware with a discharge. If you feel that this may have been the case, you should mention it sooner rather than later. Quote did that kind of test with the power supply Yeah, I'm not sure if that is very useful. A fan isn't much of a load and other than the state of the fuse, you can't really tell much from such a test. However, you also mention Quote EDIT2: I took the motherboard out of the case, and I tried powering it with only the ram, PSU and CPU. Didn't work. I swapped with the rams sockets. Nothing. And this happens with both PSU's? What kind of outlet is your computer connected to and is it connected with an extension cord? If so, what type of extension cord? it's a bit odd for two PSU's to both give up the ghost. Quote But when I putted everything inside the box, plugged everything, the power wouldn't turn on. So did you only now put it together or did it work fine all this time up until now? Quote So I looked for my Windows 7 CD, I putted it in the dvd-burner, turned back to do something quick, and when I looked back at my computer, it was turned off. I pressed the power button, and nothing happened. Did you mount your CPU cooler as per instructions? Did you install the risers? Quote Its conductivity that protects you from ESD (hence the reason you have to connect to your case in order to be protected) but you're not unfamiliar with the subject so I'll assume you didn't waste any hardware with a discharge. If you feel that this may have been the case, you should mention it sooner rather than later. I am pretty sure I didn't break anything with a discharge. But there is still some possibilities.. Quote Yeah, I'm not sure if that is very useful. A fan isn't much of a load and other than the state of the fuse, you can't really tell much from such a test. I know, but even if I try only with a fan, or only with the motherboard, or even with the whole lot, it always does the same thing: Gives power for half a second and shut down. Quote And this happens with both PSU's? It did happen with both PSUs. It was connected directly to the wall everytimes. Quote So did you only now put it together or did it work fine all this time up until now? When I tried everything for the first time, I was almost sure that the power supply was dead or something, so I send it back and I waited for them to ship another one. The only time it worked fine is yesterday, before it shut down by himself and couldn't power on anymore. I was accessing the BIOs. Didn't have time to do anything but put that Windows 7 CD in. 1-2 minute after, it happened. Quote Did you mount your CPU cooler as per instructions? Yes I did of course.And this wall outlet is in order, you've had other devices hooked up to it that did not break down? Switch on the back set to whatever voltage comes out of the mains? PSU capable of auto-switching if there is no switch? Quote When I tried everything for the first time, I was almost sure that the power supply was dead or something, so I send it back and I waited for them to ship another one. They didn't send you the same one back? Did you note the serial NUMBER for the first PSU? I'd like for you to make absolutely sure that your CPU cooler is mounted properly. Quote And this wall outlet is in order, you've had other devices hooked up to it that did not break down? Switch on the back set to whatever voltage comes out of the mains? PSU capable of auto-switching if there is no switch? Yep. Had lots of devices hooked up to it and everything works fine. And my power supply doesn't have any switch on the back to set it to whatever voltage, so I guess it is capable of auto-switching. Quote They didn't send you the same one back? Did you note the serial number for the first PSU? I ordered another of the same power-supply the same day I send that one back for a refund. Quote I'd like for you to make absolutely sure that your CPU cooler is mounted properly. Right now, the cpu cooler is not mounted since I took everything off the motherboard but the cpu and the ram. But i'm pretty sure it was mounted properly when I tried yesterday.Well, perhaps you just got unlucky and were sent another defective PSU. I would return this one as well; third time's the charm. Is the company you order these things from trustworthy? Are these PSU's sealed? I have never seen a piece of hardware break the PSU so I doubt it's any of your hardware.Some people told me that it's VERY unlikely to get a defective PSU. The company where I order these is Directcanada.com. They are very trustworthy and everything I order from them is sealed.

Try the PSU on some other hardware, then. You do risk damaging it if the PSU isn't in order but if "some people"' their opinion is important to you, then set your mind at ease by testing it! That paperclip thing doesn't really do it. At the very least, you'd need a load of some kind like a resistor. I use one of these: http://www.recom.nl/testers.html Not very accurate but useful in these situations. |
