I would like to know how I can check if my power supply is fully functional.
Mobo - ASUS P8P67 Pro Rev 3.0, BIOS 2303
CPU - Intel Core i7-2600K
RAM - MV-3V4G3D/US, 4 DIMMs
GPU - 012-P3-1570-AR
PSU - SeaSonic X-850 (SS-850KM Active PFC F3)
Mobo - Intel DP67DE, BIOS 1448
CPU - Intel Core i5-2400
RAM - F3-12800CL8D-4GBXM, 2 DIMMs
GPU - ASUS EAH5770
PSU - EA-380D Green
I have had 3 CPUs die in my system, and 2 of them were replacements that died instantly. My first CPU died while the system was booting, and I did not hear, see, or smell anything unusual when it happened. My computer had shut off as if it was unplugged. The CPU was about 1.5 years old, which is the age of my PSU. My system had not been moved in about a month, so an electrical short is unlikely.
I've already been approved for a advanced motherboard RMA, and I should be receiving the new mobo tomorrow.
I jump started my PSU by following the instructions on SeaSonic's site, and all of my peripherals (2 HDDs, 2 Fans, 1 Optical Drive) powered on.
My system's GPU and RAM have been individually tested in a borrowed system, and the system passes the POST when they're installed.
When the dead processor was installed in my system, it's PSU would not power on unless I unplugged the 8-Pin CPU power connector; but when the dead processor was installed in the borrowed system, it's PSU would power up the system for few seconds before shutting off.
I measured the voltages on my PSU's
- 4-Pin peripheral
- 8-Pin CPU power
- 6/8-Pin PCIe
- SATA power
- 24-Pin mobo
connectors at no load and with ~20W load from my peripherals. Here are the results:
- 12.30V (12VDC)
- -11.88V (-12VDC)
- 5.05V (5VDC)
- 5.12V (5VSB)
- 3.38V (3.3VDC)
- 3.25V (PSON)
I measured the same voltages on all of the connectors I checked, but it was sometimes lower by 0.01V due to the length of the cable.
Please tell me if my PSU is fully functional. If my troubleshooting is not conclusive, please tell me what other troubleshooting I should do.
The PSU should *hopefully* be in working condition. Reasons:
- 12V components survived except for the CPU
- Voltages are well within ATX 2.2 spec
- Components turned on with the 8-Pin CPU unplugged, and they were not damaged
- PSU did not turn on when 8-Pin is plugged in because it doesn't power on when there is a faulty component. In this case it was the CPU and/or mobo (VRMs?).
My replacement mobo arrived.
I decided not to take a risk by using my PSU, so I filled in the RMA form and sent it in. SeaSonic gave me the tracking # for my advanced RMA, and the replacement PSU should arrive Jan. 2. If I can confirm that my old PSU is in working condition, then I will use it until I get the replacement.
If I don't see physical damage on the old PSU's cables, is it necessary to replace them with the new ones? The voltages seemed fine, which mentioned in the OP.
My first CPU was approved for RMA without an issue. My 2nd and 3rd CPU were replaced by Advanced RMA at no cost and with a pre-paid return shipping label. Shipping was 2 day international. However, If they were more knowledgeable, I wouldn't have been the one who suggested that my mobo or PSU were the problem.
They were quick to issue an advanced RMA for me, and the mobo arrived in 4 days (=/>2 days processing, =/<2 days shipping).
After they responded to my email, I called them to ask about the RMA form and they picked up right away. They set up an advanced RMA and had the tracking # sent to me within 45min of sending in the RMA form. The PSU arrived within 5 business days.
