Yes! MicroATX is essentially an ATX board with the bottom few PCI slots cut off.

Whilst on the topic, I must also recommend that if you're buying a new PSU, make it a good one. This is something that a lot of people overlook.

Psu's are one of the things you want to buy more than you need, you never know when your gonna decide you want a new GPU, or add a second one. I'm gonna buy a Radeon 7850 soon, I could of bought a 550w but instead I ordered a 750w XFX Core Edition.

You could get a good quality 400W PSU for a system with a single HD 7850; it only requires a PSU with 28A on the 12V rail and one 75W 6-pin PCIe power connector. The Antec EA-380D is actually enough for a system with a single 7850. The XFX Core 550W with 44A on the 12V rail is sufficient for a system running two HD 7850s in Crossfire mode; a crossfire of 7850s requires a PSU with 38A on the 12v rails and two 75W PCIe power connectors. That 750W XFX is a great PSU made by Seasonic, but is WAY overkill for your system even if you planned on CF and some hardcore OC on the CPu and GPUs.

Gikkz: As prezzle stated, yes you can use an ATX PSU on a micro ATX motherboard.

Thanks for that information, as I might get CF HD7850's in the future as well!

And I was afraid my XFX XXX Editions 650W isn't enough for HD 7850 CF... Guess I was wrong. :)
