Re: A8N-SLI Premium PSU and EZ_PLUG Questions

The adapter (20 to 24 pin) will probably work, but getting a new power supply would be a better approach. There's a large variability here in terms of both power supplies and the actual current requirements of different CPUs, so it's hard to be too specific.

The EZ plug is an alternative to the 4-pin square ATX12V connector for getting power to the switching power supply on the motherboard that supplies the CPU Vcore voltage. I've seen advice not to use both of them, only use one or the other (use the ATX12V if you have it). With single rail power supplies, it shouldn't matter, but if you have a split-rail power supply, then using both the ATX12V and the EZ-Plug might cause a problem by tieing the two rails together (the intent of a split rail supply is that one rail is for the CPU Vcore and the other rail is for drives and fans, and that they should remain independent).

I have a ASUS A8N-SLI Premium motherboard which I had planned to use
with my existing power supply unit (PSU) which is a Magna ATX 600W.

1. My existing PSU has a 20 pin connector, whereas the motherboard
expects a ATX V2.0 compliant 24 pin plug. Is it generally acceptable
to use a 20 to 24 pin power converter such as
http://www.maplin.co.uk/module.aspx?TabID=1&criteria=ATX%2020%20pin%2024%20pin%20converter&ModuleNo=46201&doy=14m7
or is it better to buy a new ATX v2 compliant power supply.

2. The motherboard has an EZ_PLUG connector. What is this for, and do
I need to plug anything into it for my configuration?

3. The motherboard came with a U shaped connector (two 2cm black
connectors fixed to a 7 cm circuit board. What is this, and do I need
to plug it in somewhere?

4. Finally, both the NVDIA and Silicon Image RAID controllers support
RAID1. Is either the better (faster) choice as the manual does not
indicate this?

Specification - I have the following components:
- DVD-RW drive,
- Generic CD drive
- 4 x 160GB SATA HDDs
- XFX GeForce 6600 SLI XXX Edition 256MB DDR, PCI-E, Dual DVI, TV Out

Many thanks in advance for any responses. I'm learning as i build.
