hello,
I am new in this forum so i don't know much about how to present my problem directly to u.
I am thinking of buying a atx 6770 or gts 450 this year but after searching a lot from the internet i found out that i need to know about my psu.
My system spec...
motherboard:p5G41T-M LX
CPU: Pentium(R) Dual Core CPU E5700 @ 3.00GHz
memory: DDR3 Ram 2GB
SMPS: Frontech JIL-2414I (450Watt)

now my question is that i do't have a 6 pin pci connector in my psu.
so will i be able to install those graphics card without using a pci connector i.e can i connect them by applying different method...
Thankx in advance
 
You can get a standard molex to PCI-E adapter that would work ok. I could not find much info on your PSU so I can't say as to weather you have adequate amps on your 12+ rail to handle those graphics cards or not. If you do then the adapter will work fine and a lot of the cards come with them included anymore.
 
As a generall rule, if you cant find it on an internet search, and it claims 450 watts, its not. Its commonplace for cheap PSU manufacturers to vastly overstate the performance of their units. I would be shocked if that "450 watt" psu could handle 300, let alone 450. And I mean going out in a blaze of glory. Perhaps taking other components with it.

Just get a better PSU.

arijitdutta, your PCIex16 slot will be fine for the cards. A card may be listed as supporting 3.0 PCIe but that doesn't mean it requires a mobo with that spec. You can use a 6 pin to molex adapter but like others have said, your PSU may present a problem if it's low quality. I would get a quality PSU first and then look at graphics cards options. It's possible for a cheap PSU to damage components in your PC and can even start a fire when you may be away from home with it left on.
Having said that, I have a GTS 450 in one of my computers and it's a nice card. You can play older games on high settings on 1080p and newer games on lower settings.
 

Mercer95 is wrong...the HD6770 requires one 75W 6-pin PCIe power connector. What is the amperage rating of the 12V rail on your PSU? Does the label on the side of the PSU state if the power supply rating is maximum or continuous?
 
That is definitely a generic PSU...a decent quality 450W PSU would have a 6-pin PCIe connector. You can attempt to use it, but I would recommend getting a good quality PSU; it's an investment in the most important part of your PC and is reusable.

dont waste time, 7000 series is WAY better. AND 7750 > 6770.
 

The HD7770 and 7750 have a great performance to watt ratio, but a 7750 is not better than a 6770. At best it is almost as fast as the 6770, and has the advantages of: being a single slot card, having a low power draw, and no requirement for a 6-pin PCIe connector to supply extra power. if I was going to spend the money that a 7770 costs right now, then I would buy an HD6850. The HD 6850 is about the same price or cheaper on sale and trounces the 7770.

Yeah, the Frontech one is crap...I had one, added a 5830 (I used TWO 500W frontech SMPS, mind you) and the one feeding the card gave up in mere 3 days...it said about 19 or so Amps on 12 V line but couldnt even feed 100 W (175 total TDP- 75 from the Slot) to the 5830.
If you really wanna add a dedicated GPU, go for a Corsair or Seasonic or something might cost you about 2500 for a good one but is definitely worth it! If you plan on going for the 7750, you might end up spending more than a 6770+ a proper PSU (7750 is pretty cheap abroad but in india, anything from the 7000HD series is wayy overpriced!)
Shop smart, do a little research on ebay or something and then decide.
