8 pin power cpu question

[xbcrguy182x]

Hi everyone! Quick question, I am building a new machine and I decided to go with the MSI P6N SLI motherboard with core 2 duo e6300 cpu. I was about to order it but i noticed that the mobo has a 8 pin cpu connector. My current thermaltake pure power 460watt psu only has a 4 pin connector. Will it work? Is the 8 pin for SLI? I dont plan on doing SLI now though. Thanks!

The 8 pin connector on your motherboard has nothing to do with SLI. It is another power connector called the EPS12V.


"What is EPS12V? EPS12V is a special, non-ATX standard adopted by the Server System Infrastructure (SSI) group to provide a more powerful and stable environment for critical server-based systems and applications. EPS12V equipment is not compatible with standard ATX or ATX12V PCs found in homes and offices. Power supplies built to the EPS12V standard include a 24-pin motherboard power connector and an 8-pin +12V connector. However, since some server motherboards also use other connectors, TruePower 550EPS12V comes with 4-pin and 8-pin +12V and 6-pin Aux. power connectors for wide SSI / EPS12V motherboard compatibility and user versatility."

I don't know if your board will work without power to the 8 pin. To be on the safe side, I'd look at a non-EPS12V board.

Ahh...thanks alot. I was looking around and I saw that many SLI mobos have that 8 pin connector. Hmm, should i get this mobo and get a new psu, or look for another mobo? decisions.....lol would 460 watts be good enough for a e6300, 2gb of ram, 2 optical drives, 2 hard drive, 7600gt card? Thanks again

Look at the 7600GT specs and if your current PSU can supply the required amps on the 12V rails, you are good to go. Since the 7600GT derives all its power from the PCI-E bus, there should be no problem at all. Note that the 7600GT manufacturer may not specify amps, but wattage instead.

Whether you get the mobo and a new PSU, or look at another mobo and keep your current PSU is up to you.

Flip a coin.

It basically just provides more stable current to the processor. Until I got the PSU in my sig, I was using my old 350W PSU which only had a 4-pin connector for the CPU. My PC ran fine... WhenI put the 520W in, I used the EPS12V connector and that works fine too

This is where power supplies get tricky.
460 watts for $29.95 won't work (at least not for long)

460 watts for $75 or more will work just fine.
