HD 7970 X-Vapor rebooting computer. Help!

I've just got my Sapphire HD 7970 X-Vapor Ghz edition graphics card, but whenever I try to run a benchmark it reboots the computer almost instantly. The temperature is NOT the problem as it barely reaches 55°C. I've turned off the auto-reboot setting in Windows, but it still does it. No BSOD.

Other system specs:
AMD FX 8320 8 core processor (3,5Ghz)
1 HDD and 1 SSD disc
Rasurbo EAP Eco and Power Quiet 650W PSU
Asrock 970 Extreme 3 motherboard
8Gb Corsair RAM

I suspect the PSU, but I'm really not sure. It works fine when not at full load.

Best solution

it's the psu.
At least it hasn't gone up in smoke yet nor destroyed anything else.

Buy something from Corsair, Antec, PC Power and Cooling or any other good brand with a strong 12V rail(s). 600W or there abouts would be plenty.

edit check some reviews from Jonnyguru and get something he likes, cant go wrong with those. (might get a bit expensive thou, so pick one that fits your budget :)  )

Since you are having problems while only the system is pushed maybe your power supply is not providing enough power (7970 vaporx demands at least 500W on its data sheet) try with a better quality and higher powered psu...
or maybe psu is kind of bad and not providing its peak power under high load... its a bit tricky...

well.. he already has 650W psu but im not really familiar with the brand. or its maybe bad batch... but I agree, psu is the 1st thing to be replace in these situations

Rated watts dont mean squatt if the psu cant deliver what is promised by the marketing team. A lot of 'cheap and cheerfull' psus have gone up in smoke in reviews when tested to the advertised wattages, some only manage half before they let out the magicall smoke.

I guess he got lucky since obviously some overpower mechanism is actually working on the psu and it shuts it down before anything really bad happens. Windows auto-reboot wont affect these cases when the power is lost in the psu. That in itself is a clear sign it really is the psu...

Thank you for the answers guys! I'm going to replace the PSU and see if it helps. Is there any company that makes good ones that I should check out? I don't want to spend more than 100€ on it, but I suppose they're mostly all around 50€. I'm looking at a german site that will ship items to my country(already have an order there), so perhaps there's something good here: http://www.hoh.de/hardware/netzteile?p=1 Maybe you could help me find the best one? I translate the site to english with Chrome

corsair TX-650W modular

or somewhat cheaper one
corsair CX-600
http://www.hoh.de/hardware/netzteile/500-700-watt/15371...

be quiet seems to be popular in Germany and the quality is good
be quiet Pure Power 630W

Thank you for the suggestions!
I've looked at some 750W ones from XFX:
http://www.hoh.de/hardware/netzteile/700-1000-watt/6059...
and
http://www.hoh.de/hardware/netzteile/700-1000-watt/4051...

I've looked at the 750W ones because I may get a crossfire setup in the future(distant future). I'm thinking Corsair or XFX are the best ones. I don't really trust the "be quiet" ones... kinda think it may be similar to what I have now

If you want to do Xfire in future its best you get a 850Watt PSU something like Corsair HX850 : http://www.hoh.de/hardware/netzteile/700-1000-watt/7779...
or
little cheap Corsair TX850 http://www.hoh.de/hardware/netzteile/700-1000-watt/5502...
Any less isn't recommended.
Thanks

Thank you mate!
However I'm still thinking about getting a 650-750W, mostly because the crossfire plan ain't a 100% thing, and I don't want to spend a lot of money on more watts but less quality (again). I'm thinking the decision will be between the two XFX with good reviews or one of the 650W corsairs above.
