Hi, I'm getting a new motherboard the: MSI 790GX G65 AM3 for my next PC Build, but I wont be getting the new 650watt Power Supply for it for another month, So the ? is Can I Plug my old ATX 350Watt 20pin Power Supply in this board to make sure everything is working? I will just be runnig the onboard video for now, and 1 HDD Drive, and 1 CD-Drive, and no extra case fans. Thanks

Depending on how old the power supply is, remember their capacity degrades as they get older, but without a graphics card you shouldnt be pulling anywhere near its capacity so it should be safe unless its an ancient power supply

Assuming you have a 24 pin ATX connecter, the 350W should allow you to test/ run for a while. I DO NOT recommend you do so. Get a decent PSU (ie 400CX) or better ASAP.

the 20+4 pin connector allows you to connect it to motherboards that require both 20 and 24 pins, it just makes the power supply far more versatile.

Being 4 years old your PSU likely wont output what you need so its best to wait for your new one to come in.

Right now my 350W PSU runs a P4 2.8GHz single core CPU @68Watt, 1 stick of 512mb PC3200 ram, a total of five Fans, an AGP slot ATI 1650Pro 512mb video card, two DVD-Drives, and one 160gig Hard Drive. and 1 PCI tuner card.

Raidmax isn't the greatest brand for PSUs.

You need a new PSU or 20 to 24 pin converter.

Looks like it's 24 pin.
