i have iball baby 306 cabinet with default psu iballLPE223-400(400W) having rating of 17A on +12vrail...... i just want to add radeon hd4650 1gb ddr2 on my mobo but someone told me that my psu is not sufficient for this gfx card!!!! can anyone tell me that can i game with this card on my current psu coz i dont want to change my psu as i've bought this system 2 months ago....or suggest me another entry level gfx card which can cope up with that psu????

Best bet is the HD4670. Is this the case and are you sure the psu is 400w? This data sheet says the LPE223-400 is a 250w psu. Had to ask... Skip

If you're gonna get an HD4650, get one that has GDDR3, not GDDR2. But considering the HD4670 costs almost the same, I suggest you take Skip's advice. The HD4670 is a much better card.

can hd4670 run on that psu???

@skip here is the info for my cabinet and psu----------- http://computers.lapcom.in/online_s... cases/iball-atx-cabinet-with-smps-baby-306.html and http://techshop.in/store/product_in...

"can hd4670 run on that psu???" The HD 4670 requires less than 60W. The PCI-e x16 slot is capable of supplying up to 75W. A 250W PSU may be a bit "iffy" but a 400W PSU should have no problem. And you don't have to get a 1GB card. In fact, many of the 1GB cards are slower than their 512MB brethren because the 1GB memory runs slower. Make sure to compare the specs. I know you're not from the US, but here's a couple of Asus cards as an example. Notice the specs are identical except for the memory. The 512MB runs at 1800MHz, the 1GB runs at 1600MHz. http://www.newegg.com/Product/Produ... And here's two MSI cards...1GB at 1746MHz, 512MB at 2000MHz: http://www.newegg.com/Product/Produ... And here's an HD 4650 w/ 1GB GDDR2. The GPU core runs at 600MHz (150MHz slower than the HD 4670) but the memory only runs at 800MHz: http://www.newegg.com/Product/Produ...

thanx jam....ur suggestion is really helpfull cheers!!!!!!!!!!
