Strix 380 issue

[standarduck]

Hi

Just recently installed a Strix 380 into my machine.

Was working fine all of yesterday evening and perfectly until about 15 minutes ago. Display died, PC still running.

No output signal detected via dvi cable into monitor,nor hdmi cable into hd tv which was my attempt to work out if it was the monitor. Weirdly when I first powered on after installing yesterday, I noticed the fans did a little spin up on power on, but now I'm not getting thag at all.

Any ideas? I'm concerned it might be a power supply issue, as I'm using a 6 to 8 pin adapter to power it up due to have an awful pulse power 750w psu.

Re: the PSU, some Rainforest buyer reviews:

I bought this to power my new video adapter. Computer with PSU works till any game starts then it powers off as soon as a constant 300W ar needed. Beware.

If accurate, it's one of those "750W" that doesn't provide anything close to that on the 12v rail/s.

It blew up. Don't go for the cheap stuff, it also fried my CPU. Never again will I buy this.

Get a good PSU pronto. Don't switch your machine on again till you do.

How do I know I haven't already messed up the video card? :/

Tried a cooler master silent pro 600w. Video card still nothing. Can I test it some other way?
