I never heard of Alpine but the specs are questionable. What made you think you needed a new PSU & why did you you choose that particular one? Obviously some power is flowing thru the motherboard. Is the PSU fan spinning? Any other fans or lights? Are you sure you connected all the plugs as required? Both the 24-pin main ATX plug & the 4-pin ATX12V plug are connected to the board?

I Got a AMD Radeon 6970 and my old PSU didn't have a 6 pin connectors, + nope, no fans are running. The lights that signify a Ethernet cable is plugged in glows for a millisecond when plugging in the 24 pin connector. I'm 100% sure EVERYTHING is plugged in and the switch is on! Really upsetting considering i spent £60 on steam games!

Uhhh, dumb question. Does it have a 115v/230v switch? if you require 230v is it on 115v? Okay, that was two questions.

They are usually on the back just under the plug. Generally red and slide left/right. Often have to use an ink pen to move it. The exposed value is the set point.

You're not missing anything. It is either pre-set for the U.K. or auto-switching. The next step I would take, if you are certain all of your connections are secure and properly connected, would be to check the voltage on one of the leads. If you have or have access to a multimeter pull the four pin atx connector and check the output from the psu. It should be 12v U.S., but not certain of the voltage in the U.K. If you do not get the correct output or none at all, the psu may be dead on arrival. hth

It actually doesn't have to be connected to a motherboard, probably better if it isn't.

If you can get your hands on a psu tester, all parameters can be checked simultaneously.

Okay, thanks for your help! I'm going down to a local PC repair shop tomorrow, will see if i can get a cheap 500w+ with 6x2pins! If any more errors i shall hit you up!

May I suggest you take your 600W with you. If they're nice folks they may check it for you for free.

"will see if i can get a cheap 500w+ with 6x2pins!"

You'll be making another mistake. Decent quality PSUs are NOT cheap! Why is it you have no problem spending £60 (approx $97 US) on games & probably £215 (approx $350 US) on an HD 6970 but you want to "cheap-out" on what is arguably THE most important piece of hardware in your computer?? Pony up another £50-60 for a decent PSU or you're going to end up wasting the other £275.

EDIT: Here's a better look at the Alpine specs. It's a cheapie that's not even 80Plus certified. And I question the "Intel v2.03 enhanced +12V" rating. If you google that phrase, the only hits are Alpine & EZCool PSUs. AFAIK, there is no "Intel v2.03 enhanced +12V" standard. The latest standard is v2.31 & that was from 2008, v2.03 is from 2000:

if you require 230v is it on 115v? Okay,

If it were on 125 v and you fwd it 230 volts then the power supply would be toast and possible the motherboard with it.

It should be 12v U.S., but not certain of the voltage in the U.K.

It is the same the world over. 12v US is the same as 12v anywhere else. All PC power supplies have the same output voltages regardless of what the input voltage may be.

Testing a power supply with a multimeter will only give you limited information. That is that it probably works. The only positive information you are likely to get is that is doesn't work at all.

To test a PSU properly you need a PSU tester which introduces a load and ensures thatt the power supply can still produce the required voltage when it is working hard.
