Specs: Windows 7
Hy guys, I need some help.

I have a Gigabyte GA-EP35-DS3 motherboard. It has a 24 pin connector. I connect my PSU 20 pin connector to a 24 pin MoBo connector. I have an Intel E5500 processor in the socket. When I startup the computer, It starts but no display. When I connect the ATX12V connector tho the MoBo, the computer starts, but after a few seconds it shut off, and then starts again (endless loop), and no display.

My power supply is an old 300W. I have 2x512MB RAM.

What can I do guys? pls help.

How many Watt PSU do you recommend?

✔ Best Answer
ga-ep35-ds3 power supply requirements

The manual says > it is recommended that a power supply that can withstand high power consumption be used (400W or greater). If a power supply is used that does not provide the required power, the result can lead to an unstable or unbootable system

Look for a PSU with a minimum of 400W, a single +12v rail with at least 30A, 80 plus efficiency rating, active PFC, & a decent warranty. The Corsair 430W fits the bill. It's a good unit & can usually be found for about $25 after rebate.

Agree #3 & #4.
Another note: 2x512MB RAM is not enough if you are running Windows 7.
Your MB supports up to 8GB RAM total (probably 4x2GB) maximum:
Windows 7 32bit will run on 2GB RAM but runs better on 3 GB to 4GB (3.2GB+ usable) and Windows 7 64bit will run on 3GB but runs best on 4GB or more (for multi-tasking 6GB to 8GB is best).

You have to be a little bit crazy to keep you from going insane.

Thank you guys. I know that's not enough memory, later I will upgrade. And XP is enough for me.

If you don't even have a 24 pin power connector then you power supply is really old.

Don't buy a junk power supply. Riider gave you a suggested unit. You won't find anything decent for less.
