Is my PSU powerfull enough to run a GTX 660 TI or Radeon HD7950

[The Internaut]

Hi everybody,

I am looking to upgrade from my integrated card to a single dedicated setup. The two cards I'm currently looking at are the Radeon HD 7950 and the GTX 660 Ti. My problem is that my PSU is a Corsair 430 CX, which does not appear to provide enough power and only has one PCIE connector, where both cards require two.

From what I have found online, opinion seems to be divided as to whether this PSU can handle either of the two cards. Apparently, I could use a molex adapter to provide the extra PCIE connector, however I am still not sure the PSU will be up to the job.

My specs are:

PSU: Corsair 430 CX
CPU: Intel Core i5 3450 3.1 Ghz
RAM: Corsair 8GB (2x4GB) DDR3 1600MHz Vengeance Memory

I am also using a single SATA HD and DVD/RW

Any help appreciated!

That is not an efficient PSU for either GPU.

AMD's published requirements for a 7950 is a 500 watt PSU. Nvidia's published minimum for a 660 Ti is 450 watts. Not only is a CX 430 not efficient, it doesn't meet minimums and it's not a well-made unit.

Hi,

Thanks for the quick responses. My budget is limited so I was thinking perhaps upgrading to the 500 CX? I realise that there a lot of criticisms leveled against the CX series but I am on a very tight budget.

Then I would wait and save up for a PSU that will work for sure and is more reliable than a CX. A TX650 is only an additional $30 over a CX500.

Thanks everybody, I will take David M's suggestion and save up for a TX 650!
