My PC just keeps rebooting at random intervals. It powers on fine every time and works just fine.

The problem is that for no reason it will just reboot itself, I can play games for hours on end then the next time I play it just reboots, same applies for web browsing, encoding streaming, seemingly everything.

I suspect a PSU prob as I have quite a lot of Hardware in my comp and wondered if anyone had experienced the same thing as I dont want to shell out on a new one and still have the same issue. Hardware spec below.

DS3
e6320 + Arctic Freezer 7
X1950xt 256mb
2gb PC8500 1066 ram
Creative X-Fi Gamer
2 Sata drives
1 IDE drive
USB2 PCI Card + 3 USB Hard Drives
1 USB 4-port hub
1 Exhaust Fan + 2 80mm case fans
2 x DVDRW drives
1 USB card reader

All powered by a 480W Thermaltake PSU..

Do I need more juice?

Thanks in advance :D
 
The XT demands a lot more power on the 12V rail, It seems a PSU problem to me. Have you tried monitoring temperatures on the CPU, GPU etc?
 
Would be surprised if its the PSU unless it's faulty tbh.
To test simply unplug everything except the minimum, ie boot hd, gfx.
Then see if it still does it.

Temp are fine across the board to be honest as that was my first thought. CPU is 46/47c under load, The XT has an Accelero cooler on it and idles around the 50/55c mark.

I am really lost as to the problem, I've never had anything like this at all.
 
Even though your psu is rated as 480w it is woefully underpowered, not one of thermaltake's finer moments.

To illustrate:

A 380w antec earthwatts has 27A on its 12v rail.

Your 480w thermaltake purepower has 18A on its 12v rail.

So your supply is marketed as being 100w more powerful, yet at max it delivers 108w less on its 12v rail than the antec. Not good for a modern system, not good at all.
 
Just to confirm its a Thermaltake Xaser III Silent Pure Power 480w.

If its this then I'll have no issue in investing in another more suitable power supply.

Thanks again for the advice guys :D
 
I think I've found the culprit. I think its one of my RAM sticks.

I basically unplugged everything I possibly could and still got the same effect. So I started on my hardware. I've run Memtest which fails immediatley on one stick but passes on the other.

Could this be causing the issues Ive been seeing such as random reboots?

Looks like OcUK will be getting a call for an RMA.
