Hi
 
This morning everything fine with the computer and then a couple of hours later the most horrid smell emanating from the computer.  Quick look in Speccy at temperatures and everything was great. GPU the hottest in the 40's, recently re-pasted and cleaned.
 
So off with the power and in for a hunt around, and the PSU was hot to the touch and when opened the smell seemed stronger from that than anywhere else in the case. It is the original PSU from 2009 when the system was built (700w OCZ)
 
I have noticed recently that network transfers into the machine causes the mouse to stutter for the past few weeks but it was one of those things that I thought would investigate when time allowed.
Have had a check around the rest of the components and cannot see anything amiss and all the resisters I can get at are cold to the touch, yes there is some smell but that I think is to be expected given the smell from the PSU.
 
Am I on the right track, or should I be looking at a new computer. Personally would rather not as it still does everything I want it to and it boots in seconds (SSD drive).
 
Looking at the EVGA Supernova G3-550W or EVGA Supernova G2-650W both on Amazon for £85
 
Thanks
Paul

Thanks, not sure I am going to be upgrading the machine in the future.  It is now 8 years old so more like it would be a replacement with lower wattage components in terms of CPU and GPU.

Thanks the 750w G2 is £120 on Amazon which is over my budget really
 
Have been on the OuterVison Power Calculator and it has given the following:

• Load Wattage: 374w
• Recommended PSU Wattage: 424w
• Recommended PSU: EVGA 650W G2 Gold 80w @ £85 on Amazon

 

looks like you would be good to save some cash and go with a 500w, unless you plan to make huge changes when you upgrade, like swapping to sli / xfire and many many more hdd's / ssd's, excessive wattage will leave you outside the efficiency curve of the psu.
