Ok, I recently build my system, however the budget was limited so I went cheap for the first PSU - terrible mistake, as the second morning the entire rig didn’t power up. Exchanged the PSU for a new one, Intertech Combat Edition modular. (I didn’t know much about PSU’s at the time and was in a hurry to get everything together). Now, sometimes when I boot up the system, suse stops prior to starting x server with a black screen(the display is lit up from behind but it is all black). There is no error message, no control no nothing. The same happens if I restart and boot into Windows. I’ve got grub-uefi and win 8. I kept restarting with no success, and had no clue what to scout for first. Bios was working fine, all params looked ok, no overclocking done, nothing to hint on this.
I then, unplugged the rig all together, gave it about 1 minute and restarted. Everything booted up properly now. I haven’t made any kind of overclock to the GPU. The CPU is AMD fx8320 and has turbo enabled in bios and activates in windows as well when starting. It goes to a max of 4.0Ghz from the default 3.5. Other than that, everything is default.
GPU is Sapphire 7850 OC edition, with Asus M5A97 LE R2.0 edition. The RAM is a cheap Kingston 8.0GB 1333Mhz.
I am suspecting the PSU for being at fault with the startup issue, considering the way it gets resolved(unplugging everything). I believe if the ram, CPU or GPU was at fault, I couldn’t start it at all nor would have any stability in games or otherwise.
I want to know if anybody else shares my opinion regarding the PSU, or if you have any other suggestions. Should I change the PSU? Is there any fast inexpensive way I can put the PSU to a test?
If it needs changing, what else should I buy? The price of the psu was 60$ or 220 lei(Romanian currency). Shouldn’t this be decent? The rated output is 650(or at least so the label says).
Thanks in advance for your help.
