No - get a branded one. You only need 750W really unless you're going SLI.

No, again that's a poor power supply.
Something like this is only a few £ more expensive but well worth it.

Will leave you plenty if headroom to overclock you Bulldozer cpu in the future too.

"This 750W PSU is designed for entry level systems that require a lot of power."
Well that sums it up really. Your PC is not entry level by any means.
Can I just ask a quick question... Do you have something against branded PSUs?
some of the branded PSU's are generally good and well priced and those are alright but some are hideously overpriced for a low wattage

When it comes to PSUs it isn't all about the wattage though, that's the thing. You can have a 1200w PSU but it if has rubbish efficiency you'll not get anywhere near that, nor will you ever really need that unless you're going tri/quad SLI.
Anyways, the branded PSUs are always better, you get a nice warranty usually just in case, they are efficient and the wattage is suitable for what the user needs.
This, I also wouldn't want to risk the rest of a build by going with an unknown brand of PSU that could end up ruining anything its hooked up to.
With buying a known brand you can be fairly sure that you wont have any problems.
A lots been said about PSU's all ready but to add alittle more:
Cheap PSU's tend to do various things such as quote their maximim output rather than sustained, have very low amps on the 12v rail (which is the place where it counts). The PC's before yester year took most their juice from the 5v/3v rails, many cheap PSU's still provide a large chunk of their output in this range (they can advertise higher watt rating this way), which is absolutely useless for todays systems.
Another trick is testing at low temperatures which naturally allows the PSU to take more punishemnt and throw out more power before it dies, rather than test at the more realistic higher room/case temps. This allows them to state a higher output rating not reproducible in real life scenarios. Or simply they just tell blatent lies, which they can get away with as a result of the lax regulations where they are manufactured and the units taken just at their word at every stage.
You can find many reviews of poor quality 400-600w psus crapping out well below their quoted output.
Quality PSU's will have better quality components/design that will last longer giving the PSU a longer lifespan, allowing it handle higher loads better, with greater eficiency, stability and reliabilty etc
The list is almost endless tbh.
However many ppl with undemanding sytems can get away with cheapo units trouble free which is a problem as they think they'll be fine when they build a more demanding one.
As has been said it can potentially do damage, or it will simply fail to provide enough stable power and youl get sytem instability/bsods etc.
One thing to watch out for, just as wattage is no indication of how good a PSU is, neither is price, so you can still find some ***p PSU's at the price boundary of the quality ones.

Rule of thumb, you pay for higher quality and efficiency.
E.g.: Higher priced models will be more efficient - look for the 80 Plus rating.
Not all capacitors are created equally - the cheap ones will tend to fail/bulge/explode where as the more expensive (usually Japanese ones) will last longer.

Sorry - Are you not taking anything in? ._.
well so far people said about high quality and 80+

I think this is a lost cause folks!
Get a PSU suited to your sytem, PSU's have low efficiency at low power draws so no point going for 750+ watts unless you are definitely planing to go for a dual card setup and overclock.
The reason to go for 'branded' (thats just to say they've been around some time and have built up a reputation) is that there are specialist review sites that take apart PSU's and inspect the hardware and then test the charecteristics of the PSU under various load conditions. Ones being reccomended will have a good track record of providing good quality power supplies. If you're lucky you may also find a review article specifically testing your model which is reassuring.
btw 80+ was refering to efficiency not price. There are good 80+ psu's in the £50-60 range.

We have told you time and time again, the PSU that you linked to will not supply 750W decently - what I mean is, 750W reliably (i.e. supplying 750W when the case in 50*C inside, low ripple and noise on the rails ect).
Poor quality PSUs have been known to take entire systems with them when they fail.

Look at my post. Read the statement in quotations.
I've got another question for you. Why do you insist on going for a non branded one when for another 4 pounds (4 pounds!!) you can get a decent branded one that comes with the benefits of the branded PSU.
You and me both.

I think this is everyone's face towards the OP:
That's definitely the face I'm pulling!
The OCZ 650W one that both shadow_boxer and I linked will be fine for you at a price point in your range based on that unbranded one you linked, asking if it was OK.
If you aren't going to listen to people who are giving you good advice then it's your call. Buy the cheapest you want with the 'wattage' you desire and see what happens. Let us know
