Could you run a Log in Corsairlink whilst playing BF4 or something then post a few lines on here.

I have a 760i and mine only rarely breaks 450 let alone 500.

Wow this thread escalated quickly!

He's going with a 850w unit

Went for the evga 1300w G2 unit myself, I got burnt using an 850w PSU whilst overvolting a pair of 470s, took out the PSU and Motherboard in one nasty swoop. I'd previously run a pair of 5850s so assumed it'd be ok. I'd rather have power to spare.

Well if it only draws 5xx watts then go with one of these.

What's the worst that could happen??

730 to 850 watt PSU in my opinion (as others have said - get a good quality one)

If its the corsair rm850 that's on sale.. beware. It's likely one from the faulty batch with the broken OTP protection

Yeah, not a good choice. It's cheap for a reason.

Corsair say it only happens in high ambient but theres been reports of it happening at normal room temperature. If your system causes the psu to run at moderate load (stressed but not enough to engage the fan) then it will shut down eventually due to overheating.

For a 100 pound budget I'd recommend the Seasonic G-750.

Might be old stock ocuk is selling, why else would it be cheaper than the 750 version?
