this is my power supply:

it's a 550 watt,i have this on my pc and it's a cheap one,not of any good brand...........
i want to buy an hd 5670 with this power supply,is it ok to handle that?
my system is :
intel c2duo e4500 2.2 ghz
2gb 667mhz kingston ram
intel dg33fb motherboard
1 samsung dvd rw
1 250gb seagate barracuda hdd
2 cheap case fans

also,i'm planning to overclock cpu to 2.6ghz,so processor will consume more power.......
so after all this,is it ok to be with my current psu?
if not,then please explain the problem in detail.....

Yeah, you'll be fine, the 5670 sips power as well as your CPU.
It is a VERY OLD PSU though.

It will probably run a HD5670 but it only has the specs of a 350 watt PSU today. A PSU upgrade is recommended.

You need to rephrase that IMO, its was perfectly fine 550W PSU in 2002. It just has the specs of a :modern: 300W. :lol:

Most newer tech isn't able to handle cheaper PSU's of local brands. Add overclocking onto it and BOOOOM!!!!

There's something that people need to understand that PSU's are more important than it seems. Just because they don't add a few FPS to games or reduce the processing time of a video encoding, doesn't mean people can put anything in there.

I would suggest a change of the PSU. Get a Corsair CX400W. Since you would be overcloking, VX450W would be good.

i don't have money for good brands.........
but cheap brands are much cheaper,i mean,can i put a cheap 600-700watt to ensure that it's at least equal to 400watt branded ones?

Skip the PSU, the one you have can drag you along till your next upgrade. a 400Mhz OC on a C2D is nothing.

You can compensate on the power by adding a whole lot more but can you compensate for the ripple, weak rails, PFC and other factors involved in a PSU? Your 550W PSU wont even be able to deliver 20A on its 12V rails. Corsair VX450W delivers a constant power of 33A on its 12V rails plus it can deliver more power than its rated at, i.e. , 450W. I guess you need to do a little bit of reading on what PSU is in modern times. A Corsair CX400W is only 2600 INR and a VX450W is 3600 INR. You can also get Gigabyte Superb 460W at 2200 INR. Which is good.

But anyways, that is upto you.
