Any issues with this upgrade

[simon12]

I just got a Dell Optiplex 390 with a I5 2400 (used for £100) which I plan you use to replace my Phenom x 4 @ 3.6GHz are there any issues with using the dell motherboard it has a PCIE slot and is a standard form factor but only has a 4 pin motherboard power connector instead of 8. I am 99% sure there is no issues but just want to check. I have no idea what the motherboard is as there is nothing to indicate on it and dells site gives no info.

Other components
2 x 4Gb DDR3 1600 RAM
Radeon 6950 2Gb
2 x 500Gb SATA HDDs
Corsair 750W the TX one
Standardish no brand case but a good one (the dell one is to thin for a graphics card)

Components to be replaced
Asrock 880G Extreme 3
Phenom x 2 550BE Unlocked to 4 cores and @ 3.6GHz

I assume I will need to reinstall windows 7. Are there ant other issues & is there any reason to not use the Dell board

It will be ok, but it will always say Dell when you boot it up, and alot of the bios will be locked down.
