Possible PSU Problem?

Hi,

My PC which is about 4 years old now has just started behaving a bit erratically. Most nights I leave it in sleep mode and it usually starts back up fine, however the other day when trying to turn it back on it had switched off completely and when pushing the power button nothing happened. I switched the mains off and re-attached the cable in the back of the PSU (XFX Pro Series 650W) and it booted up alright. It worked for about a week and the same thing happened today. I just wondered if this was an early sign of a failing power supply or something else? If yes, could anyone recommend a suitable replacement?

The specs of my PC are - Intel Core i7-4770K 3.50GHz, MSI HD 7870 Black Knight 2048MB GDDR5 PCI-Express Graphics Card, Gigabyte Z87-D3HP Intel Z87, Crucial Ballistix Sport 16GB (2x8GB) DDR3 PC3-12800C9 1600MHz Dual Channel, SanDisk Extreme SSD, XFX Pro Series 650W XXX Edition Modular '80 Plus Bronze' Power Supply.

Thanks
 
Hi,

Thanks for the reply.

The PSU has not been overclocked and I have not made any recent alterations to the windows settings. In regards to the CMOS battery, isn't it usual for the time to start misbehaving, or are there other signs?
The PC has been rock solid since building it, so I'm a bit bemused by the behaviour. I'm wondering if the culprit could be the AC power cord or the socket extension.
 
No, I left it in sleep mode overnight and it had switched itself off by the morning. I tried waking it up but nothing happened and there was no response from pressing the power button, so I turned the mains off and gently wiggled the ac power cord in the back of the PSU, turned the mains back on and it worked again. This behaviour happened a week ago and it seemed to be working like usual, however it happened again the other day so I'm now so wondering if something's not quite right.
 
Unfortunately I don't have another one to test it with. Would it be a good idea to buy a new one as a precautionary measure? If yes, should I replace it with the same one or something else? I do plan to upgrade to a 4k monitor in the not too distant future, so might require something a bit more subtantial. I currently have a MSI HD 7870 Black Knight 2048MB GDDR5 PCI-Express Graphics Card installed.

Thanks
 
Thanks for the advice.

Would the Focus Plus 650w be a suitable replacement, gold or platinum?

As my current PSU is very outdated, does the same apply to the rest of my components? If yes, would it be better just to use it untill it breaks and then just build a new PC?
 
Think I will stick with the modular PSU for the time being, I think it would be easier just to plug the existing cables from the old PSU into it and save some work with cable management.

The Seasonic gold 80+ sounds ideal and good value for money. I will wait then and upgrade my system in the near future when the newer technology surfaces at a good price.

Thanks for all the help.
