PC Restarting When Under Load.

[EsaT]

If applying overclocking and removing fps cap doesn't cause anymore problems then cause was pretty surely PSU.

What was the specific model number of that BeQuiet?
If you're willing to do "autopsy" that might give hints to what part failed.
(suspect capacitors, with few of them likely bulging)
Waiting couple days with it disconnected before opening it basically guarantees there's no charge remaining.
Even if BeQuiet cheaped in costs and there's no "bleeder"/discharge resistor, leakage current of electrolytic capacitors starts emptying them once not getting power.

I'm out at the mo but when I get back home I'll look it up.

Edit: ok, the model number is Z1-650W (Power Zone).

If I were to highlight its age, would it be a viable option to sell the old unit, or should I just recycle it?

I thought I'd upload a couple of pics. They might provide a bit more info.

Out of interest, I'm trying to work out how to solve this minor problem. Below is a pic highlighting fan connections, however, the new PSU doesn't have these and the motherboard system fan ports look to already be in use. I'm still left with one fan that I can't seem to find a suitable connection for/or one that works. Any ideas?

You can get an adapter that allows you to connect more than 1 fan to a motherboard fan header, just an example:

That BeQuiet serie is made by FSP and surprisingly using Teapos instead of FSP's older "trademark" C(r)apXons.
Though 6-7 years would be long time for those in enthusiast use.

At least without testing with oscilloscope and some load would consider it WEEE ready.

Thanks. I can now see one spare connection on the board but it's not ideal as placed in the middle / very tricky to get to (the cable would be at full stretch anyway as connected to the fan on a case door).

So, is it not quite as bad as first thought then?

Definitely far from worst.
Once BeQuiet even had PSUs with infamous Fuhjyyu capacitors. (same time with Antec)
But neither exactly any high quality made to last long time in enthusiast use product.

Though not the greatest capacitors would fare better if kept cool, but BeQuiet is agressive in slowing down fan speeds.

Since installing the new PSU, which has been solid so far, I seem to be able to run higher CPU clocks (without tinkering with advanced settings) and also, enabling XMP in the bios. Now, the ram runs at the right speed: 2400Mhz.

I assume it's stable as I've done a couple of long video renders with no problems. Quite surprised.
