How Much Power Will My Upgrade Need To Run

[lilclungy]

Hello
Need A new PSU (for Cheap)
Ive Currently Got A 300w (Microatx Size) and Im upgrading
I Dont Know What I Should Get

Currently Ive got:

• An Intel D915GAG mobo
• 1 Optical Drive
• 2 HDDs (80 gb and 1tb)
• No Graphics Card (mobo VGA out)
• An Intel Celeron D 2.8ghz Processor
• Microatx Case
• 4GBRAM

And I Am Getting:

• Ati 5770 Graphics Card
• Second Optical Drive

And I Dont Think My PSU Is Going To Have Enough Grunt To Power it

How Much Power Will I Need To Run It and if there's A compatible Micro-atx PSU for that amount??

PS Will a ATX PSU fit into a Micro-ATX Case??
Thx, Lilclungy :blink:

Atx power supply won't fit in a matx case, you'll need a matx psu, I would invest in a 500w psu. your system will use around 390-410w when in use with the graphics card.

The Problem With A New Case Is $$$$$ And Rearangeing Every Thing

I Was Browsing And Found This 470w Athena Power AP-MP4ATX47FE Newegg.com - Athena Power AP-MP4ATX47FE 470W MicroATX / SFX12V / EPS12V / ATX V2.2 SLI Ready CrossFire Ready eMachines, HP Upgrades/Replacement Power Supply - Power Supplies

It Says Micro-Atx Up the top but im not sure if it will fit can someone please help.

The Athena PSU will fit your case. I just built a media centre pc and bought a mATX psu, they are very small, so you won't have any problems.
