Graphics card needs external power

I have a 500 watt power supply and recently bought a graphics card which requires a 6 pin (i think that's what its called) but I'm not sure what to do with the wires from the psu. There is currently a straight 4 pin available but it needs to be 3x2 in a block for the graphics card

Any help would be much appreciated.

The straight 4-pin that you're referring to is most likely a molex cable. That is not a PCIe power cable. What power supply do you have? Please name the brand and model.

I remember seeing that PC on ebay before, it's honestly not a bad pc for the money but that power supply has got to be a cheap, no-name fire hazard.

Get one of these, depending on what your budget can stretch to:

Its a Telsa Black PSU.

One ebay seller states the following in the description of his listing:
PLEASE NOTE THIS IS AN ENTRY LEVEL POWER SUPPLY AND WE WOULD NOT SUGGEST USING WITH PERFORMANCE GRAPHICS CARDS.

Also, what graphics card are you using?

You sure it's telsa? because that same seller has an ACE 500w that has no GPU connector on it:

Either way, it needs to be replaced to enjoy that 270x

Hm, perhaps! I'm with you on this - 650watt psu really should be about right for a 270 setup with room for a few modifications.

So if I were to replace it what'd be the best? I'm really low on funds at the moment after buying the pc graphics card and network adapter o-o

I think any half decent 450w or better would handle a 270x, no need to blow the budget :) 

For £35 this really is a bargain: http://www.aria.co.uk/Products/Components/Power+Supplie...

Or heres a corsair VS450 (V2) for £27: http://www.cclonline.com/product/99687/CP-9020009/Power...

The XFX is definitely superior to the corsair in terms of quality but neither are dangerous, both would meet your needs and both are a huge step up from your current supply OP.

on the xfx specs it says it has 0 6pins for graphics cards, would that be a problem?

No because it has an 8 pin, comprised of a 6+2 pin connector - you connect the 6 and leave the 2 hanging :)

Ah i see! So what would be the disadvantages to taking the cheaper option?

Well I'm using the VS450 myself and it works, and is within ATX specifications for ripple and voltage. It comes with a three year guarantee instead of 5 like the XFX, which hints at the cheaper overall build quality.

Lack of power -- system doesn't start or it crashes while you're working.
It blows up - even the best PSU can blow up but they are built with higher quality capacitors and usually do not fry other components when that happens.
It blows up and fries other components - the PSU is literally attached to everything (except the case) and has to power everything, so it can also fry them.
Poor ripple suppression, voltage regulations, etc. will degrade the life span of electrical components.

Having a quality power supply is VERY important.

Wait a minute... you said 270x and one 6 pin connector. I thought all 270x models needed two connectors, not one?

Both of the power supplies I mentioned are sufficient for your needs btw.

By the looks of it, it's plugged in followed by a 6 pin connector from the psu.

here's the model:

That explains it. It's a 270, not a 270x - the 270 needs less power and doesn't need a second 6-pin :D 

Yeah both the xfx and corsair would power your rig just fine
