Freddalf Posted August 31, 2009 Share Posted August 31, 2009 I have questions regarding warranty and how to best explain to the reseller about this problem. I've had issues with my PSU since I bought it about 5 months ago, and I haven't investigated it until now when I have discovered some actual issues with my Powersupply. Background: Ever since I bought this PSU I've had a beeping noise when I've powered off my computer. Just as it cuts power it produces a loud but fading beep from the PSU (and yes, I have traced the noise to the PSU). Recently I found that one or more of my SATA disks clicks regularly. But when I tried to pinpoint wich one it was, I found that ALL my SATA devices was clicking at the same time (on both SATA power channels) at regular intervalls. Upon this discovery I decided to check my voltage levels by using the only program for checking I have installed, CPUID HW Monitor, and it shows for +5V: 4.30V and even supposing there is an error in measuring, it is REALLY REALLY low. Is this a solid case of a faulty PSU? So, to beef up my proof so no retarded techsupport from the reseller returns a no-fix and takes my money, is there perhaps a more sure and secure way to measure voltage? Since my Old PSU was 580W and it ran for 2 years previous, the 650W should be sufficiant. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted August 31, 2009 Corsair Employees Share Posted August 31, 2009 What does it show the Voltage is in the MB BIOS in Hardware Monitor? Link to comment Share on other sites More sharing options...
Freddalf Posted August 31, 2009 Author Share Posted August 31, 2009 Good call! It reports 5.03V, wich is all fine. However, it does not explain the power-off noise or all my SATA drives clicking at the same moment every 10 seconds. Are all +5V on the same grid? Because it is quite straightforward to measure with a multimeter for dips. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted September 1, 2009 Corsair Employees Share Posted September 1, 2009 You can easily test a power supply for functionality with a simple paperclip. First, disconnect all the cables from your motherboard and other devices, but leave the power supply plugged into the wall. Next, bend the paperclip until you have a U shape. Find the 24-pin ATX connector and plug one part of the paperclip into the socket where the green wire ends, and the other end into the socket where a black wire ends. Make sure the power switch on the back of the PSU is on, (should be the I symbol) and the fan should spin up. If it doesn’t, your power supply may be bad. If you’re uncomfortable with this, numerous online retailers sell “Power Supply Testers” that come in a variety of forms and prices.
