New video card, computer crashing

[ISimplyFallenI]

Since I got my new 7870 I've been having a problem where my computer completely crashes. It happens whenever i play games like Metro 2033, Crysis 3, Planetside 2, and Skyrim. So I'm sure it's whenever i put the video card under heavy load, I have the latest drivers for the motherboard and the video card. I have a thought between it being 2 things, the card itself or the power supply. The reason I say the power supply is because it's 500 watts which is what the video needs and it's quite an old power supply around 6-7 years old but than again it could just be the card.

What are the full specs, if you wouldn't mind?

It may be a driver issue. Which card did you have before this?

Have you applied any overclocks to anything? If so, set everything back to default and re-try. There could be a number of reasons for your issues, but its very likely the PSU.

There's no overclocks except for the card which was factory overclocked

How are you powering the card from the PSU. It requires 2 6-pin PCI power connectors, right? Are you using adapters to power the card?

I'm using one 6-pin and 2 molex to 1 6-pin because this card only has 1 6-pin connector

I'm guessing that right there would be the issue. I think you may need a new PSU to properly power your new card.

Okay I'll be getting a new one soon

Cool, just make sure it has the right connectors. Don't use adapters.
