PC switching off.

[Ichy]

I recently bought a replacement graphics card for my PC. World of Tanks on full graphics runs fine, maybe not as high a frame rate as I expected. I tried Battlefield 3 on full graphics and within a few minutes the PC switches off and starts up again. No errors, just a click.

I only have this problem when I run battlefield 3 in full graphics mode. I had assumed that my power supply was a bit underrated but I've checked and it is supposed to be 875w, model is N875EF from a Dell workstation. I tried https://support.asus.com/powersupply.aspx and it suggested a 700w supply.

There are not a load of cards in the case, basic specs are:
Processor - Intel(R) Xeon(R) CPU X5650 @ 2.67GHz
Video Card - AMD Radeon R9 280

PLDS DVD+-RW DH-16ABS ATA Device [Optical drive]
Samsung SSD 840 EVO 250GB [Hard drive]
ST250DM000-1BD141 [Hard drive] (250.06 GB)
ST3360832AS [Hard drive] (360.08 GB)

24 GB RAM

A couple of 100mm fans.

Any thoughts on why it might be playing up?

replace that shitty psu would be the first step.

you will need a decent single rail PSU. the chances are that cheap dell thing is multi rail and cant hack the pace of alot of current on the a single line (you will most lekely need at least 2 12v line to the gpu) and the over current protection is kicking in, or its just crap - i am going for the later

Check temps
Check the event logs

You will need a new PSU anyway.

Now I have a sweat on because I just bought the same video card from a forum member and I'm worried he's just taken my money and run :p

If the problems are card related, which I'm confident they're not as I tested the car thoroughly before posting it, then Ichy will receive customer service of the highest quality.

On a slight tangent, dydey90 didn't buy from me, I assume he bought from someone I sold a card to who was then wanted to fit watercooling to the card but was unable to so resold the card.

I don't even have the card yet and things have already escalated into a new CPU, motherboard, RAM and a blu ray drive. My DVD drive is having an identity crisis and firmly believes it can only read CDs. That's what I get from a £10 special...
