Can my Chieftec 450W PSU run the GTX 760?

Hi, I posted another thread earlier today trying to figure out what GFX card to get and after some advice settled for the Nvidia GTX 760 being my first choice... (http://www.tomshardware.co.uk/answers/id-1994652/upgrading-system.html)

That decision relied on the GTX 760 being able to get enough juice from my Chieftec gps-450aa-101a 450W PSU. It does seem to deliver enough amps and watts (just barely but still), now my main concern is that it might not have the actual connectors and plugs needed. I'm not at home not so cant physically check and ideally I want to buy my new graphics card before going home. Nvidia mentions that the 760 gets power from two 6pin connectors, and somewhere on the net i see mention of one 8pin and one 6pin. My PSU seems to have neither tho, if you check this image:

Any thoughts? I'm thinking it's a no-go and that I need to get a new 500W PSU.. which will probably make the whole buy a bit unaffordable at the moment... Means I will have to go with a GTX 660 or Radeon R7

That PSU shaped doorstop is not up to the challenge. Sorry to be the bearer of bad news, but it's better to know now than try it and find out the hard way. You really need to invest in a high quality PSU. It's the most important component in your computer if you want a stable long-lasting system. That Chieftec PSU is a ticking time-bomb that should be replaced with a quality unit ASAP.

Yep that was my hunch as well. Dang, I was prepared to settle for the GTX660 but after seeing the 760s specs I really want that one. But all put together makes it 300€, a bit more than what I was looking to spend originally. On the other hand, it the 760 will probably last me a lot longer.

Also, I want to add that I would never myself buy such a cheap and crappy PSU. The fact that I got this one is the result of letting a guy I know who has a PC store do the last upgrade for me because my PC was suffering from a bad MOBO. I guess the former 1000W (!) PSU was decided to be faulty or whatever, and was swapped to this "doorstep" as you put it.
 


Hi - There are several variations of the gtx760, some require a 6pin, some 2 6pin, some 1 6pin & 1 8pin(6+2), and there's an ITX model that requires 1 8 pin.

Your Chieftec should have 1 6pin included. which I believe it does. Some GPU's include a molex (peripheral) to pcie adapter cable. Your PSU does have molex cables, so you can use a molex to pcie adapter.

You are correct, the PSU has enough juice to run a sys with a gtx 760 if it can deliver it's rated specs. That's
not always a given with lower quality units. I do suggest you save up & upgrade your PSU when you can.

If you settle on a lesser GPU than you want, you will surely 2nd guess yourself. I personally upgrade my PSU when I realized I had a POS PSU, and waited 2 more month's to get a GPU. Not sayin that's what you should do, but food for thought.

Ok thanks, that's what I'm thinking. I usually cheap out and buy something less than optimal to save cash and always wind up regretting it, so not gonna do that this time. It is my birthday 15.2 so maybe a new PSU and GPU will be a good birthday present for myself :)
