The desktop configuration as follows:
CPU - Intel 2.9 GHz LGA 1155 G2020 (stock heatsink/fan), TDP = 55W
GPU - Sapphire DUAL-X AMD Radeon R9 270X with Boost OC 2 GB, TDP = 180W
PSU - Corsair VS550
MB - Gigabyte GA-B75M-D3H
SSD - Kingston SV300S37A 60GB
RAM - Corsair Vengeance DDR3 4 GB (stock heatsink)
CAB - Cooler Master Elite 311 Mid Tower (stock cabinet fan)
OS - Windows 8.1 Pro x64
DRIVERS - Latest AMD Catalyst ver. 14.4
This new system was assembled yesterday; to dedicate the computing resources to the BOINC Einstein@Home project. So it is supposed to be run 24/7/365 (at least planned). Am using the ATI OpenCL-optimized BOINC client. I strictly do NOT intend to play games and strictly NO overclocking. All components always run at normal / reference speeds for stability.
PROBLEM: The system shuts down abruptly within 3 - 5 min when the GPU load goes Max (>99%). At max load, the temp stays between 72 - 75 deg. Cel (GPU-Z readings during the death time). This is happening when using BOINC client or FurMark stress test. This does not happen when the CPU alone is stressed (ran a Prime95 stress test whole overnight successfully without any error).
Also, I ran the Windows Memory Diagnostic Tool and found no problem. Just to mention, while I did some research on this problem, I found out that most point at PSU as the high probable suspect, but,
* Bad PSU: Even though Corsair VS550 is entry-level, I hope it delivers the power which the system is expecting,
* Lower Amps on +12V line: Corsair VS550 spec says, it delivers 42A on +12V line at 240V-5A. I live in India, so it is 240V and I plug the PSU mains into a wall socket directly which is rated at 5A. I hope 42A on +12V is sufficient for R9 270X and the CPU.
Am totally confused what could be wrong. Please advice.
