Graphics Card Upgrade - No Power Supply ??? Help Required please ?

Hi all,

I have just purchased a Radeon R9 270 (not x version)

The problem is that it seems to require a power supply from the PSU/Board which I cannot locate any cables for it?

My board is a Asus F1A55 R2.0 with a PSU Case of 450w?

Do I just need to change PSU so I have the correct supply cable or can I buy some sort of adaptor of some sort to get power from the PSU?

The requirement for the Graphics card states this?
500w power supply or greater with one 75w 6-pin pci express power connector req
600w power supply with 2 75w 6-pin pci express power connector

Your help is much appreciated on this one please?

Thanks

Simon

 

Looks like, as you stated, the manufacturer suggests a 500W power supply for that card. I think the X model requires the 600W. What brand is your power supply? Psu's that come with cases are often of low quality - some claim a certain wattage but in reality they cannot get anywhere near their max ratings. When poorly constructed psu's fail they can destroy your motherboard and other components. Antec, Corsair, Seasonic, to name a few, are considered to be of decent quality. Check your make and model PSU online to see what the chatter is about it. If you determine you need to buy a new power supply, research any models you consider. Check enthusiast sites and the like. A little research now can save big headaches later. Trust me - a power supply is not something to skimp on.

My advice to you is to use one of the wattage calculators that most manufactures of computer components have on their websites. Newegg also has a decent one. You can input what and how many devices, RAM, video card/s, fans, etc. your computer has, and get a pretty good idea of the wattage you will need. Another major consideration when talking PSU and video cards is amperage on the +12 volt rail/s. Check your cards documentation and see what the minimum suggested amperage is.

Your card should have come with a power adapter - bit if not,they are available online for cheap. Not sure if that card uses the 6-pin or 8-pin.
