PSU

[optimist]

ok this is a n00bish question, but i have to ask it.
ive just got my hands on a A8N-SLI deluxe and a 3200+ Winchester 64 Cpu and an asus N6600GT. but when the last thing i needed to connect was the Main power cord, i noticed the diffrence. the motherboard uses a 24 PIN and my ATX PSU only uses a 20 PINs. now that i was not informed of this by either my dealer or asus site, i kinde got pisse cos i just spend alot of money on a new case and PSU ( they came together so i cant just return the psu). so i didnt connect it, and my question is just to be sure .. can i use the 20 pin or do i need to get a new PSU .. and if so, any suggestions .. cheep one pls ( no money left .. lol)

Most mainboards work perfectly with the 20 pin connector. You could get a new ATX 2.0 PSU but if it works (and the PSU is high quality) never mind. You can also get a converter if you like the holes occupied.

ok .. thx .. whold u by any chance know if my motherboard will work with only 20 pins .. manual says nothing about that.

My understanding is that the 24 pin connector was introduced, so they could do away with the aditional 4 pin 12v ATX connector. So long as you plug in the 4 pin on the mobo, you should be fine.

It depends on the MOBO, but most will work as far as I know. I have run into this once and didnt hat any problems. The worst thing that will happen is it wont power up.

That's funny Optimist, I just experiened the same thing you did--same motherboard and all! I purchased an Antec True550w PSU and the damn thing had a 20 connector pin. Grrrr!

Sending it back and getting one with a 24-pin. Don't want to take a chance with that 4-pin deally.

You're going to want a lot of horsepower for that new rig. E-bay your old power supply and get one that will better serve your new motherboard. They are recommending ATX 2.0 PS with (2) 12v rails and a total of at least 480 watts for that board.

Abit IS7 - 3.0C @ 3.6ghz - Mushkin PC4000 (2 X 512) - Sapphire 9800Pro - TT 420 watt Pure Power
Samsung 120gb ATA-100 - Maxtor 40gb ATA - 100
Sony DRU-510A - Yellowtail Merlot

When calculating watts for your PSU, the max sustained wattage draw from your components should be no greater than 60-70% of your PSUs rated wattage.

You know, I've used that wattage calculator before, and it recommends a 328watt PSU. I just noticed that my specs actually total 278 watts, lol and here I was wondering if the 400w <A HREF="http://www.newegg.com/app/ViewProductDesc.asp?description=17-104-935&depa=1" target="_new"> FSP Blue Storm </A> would be enough power. Once again, here's to paying attention

The more buffer that you ahve between rated wattage and continuous load the better. You will get voltage spikes when components start. The 60% continuous use of max rated load is the absolute MOST that I would allow and I would be more comfortable with less than 50%.

<--Just noticed my upgrade to addict!

Agreed on both points. The cool factor is another reason I recommend ATX12V v2.0 PSUs.
