Is my Pc upgradable to Ati Radeon HD 4770 ?

[varunmehta11]

I've been gaming on my XFX Geforce 8400GS PC with just 300W PSU for 2 years now & had no problems.
Now i'm planning to upgrade to Radeon HD 4770. I can't upgrade the PSU since its a Lenovo OEM Pc.
Will 4770 be compatible with my pc (also my pc doesn't have a PCI Express power connector and my current gpu draws the current from the motherboard) ?

My PC Config :
Intel Pentium 4 3.06 Ghz HT
Intel 945G chipset
2 GB dual-channel DDR2 ram
80 Gb hard disk
Windows Vista Ultimate SP1

Do you know which model it is? You'll need a PCIe power plug for the 4770.

And no you can't upgrade that setup to a Radeon HD 4770 for many reasons.

The Lenovo might be low profile, so we need to know the model.

Someone tell him you CAN upgrade the PSU and WILL have to upgrade the psu...Ed im all for telling him how sucky his pc is but don't act like that or your just as bad as sharken....mention its his psu and you think he will be bottle necking the card badly etc....don't troll man

My pc is Lenovo 3000 series 8822 11Q.
Also the problem of upgrading the PSU is that it also supplies power to my Lenovo LCD monitor.

for many reasons? doesnt he just need to upgrade the PSU? or will his motherboard bottleneck the card's performance?
