PCI Express Video Board power cords

I just installed a ASUS EAH4770 PCI Express video board into a machine a few years old. There is an "auxillary power cord" to connect from the board to power. The cord plugs into the board, then splits into two separate standard sized power connectors. Unfortunately, there was only one such available connector.

I seem to dimly recall something about this not being a problem, so I went with it by plugging in the the one, and leaving the other not plugged in. Then I fired the machine up and it works.

But I am wondering if something is seriously wrong with this configuration that is begging for trouble.

I like PranjalB's answer! Feel a bit safer now.

modserv: not going to overclock afaik. However, I am wondering if it makes sense to pick up a splitter so I could plug the other side in. Does that accomplish anything?

Commented:
Sorry, I'm not expertised in that, But in my answer I'm sure that the overclock will make it instable but in the current status it will work like PranjalB said.

Callendor (as in WOT?): machine is not a Dell. Not sure why you thought that.

So -- suggestions? Would a new PS be needed to get the rest of the power?

(Yes, WOT!)

I must have been reading another question about a Dell - sorry about that.

A good power supply is an investment for several years.  It will hold up under heavy power demands and not fail (which is known to have serious bad consequences for the rest of your system).  I would recommend those that have more than 40amps on the +12v rail and a 80+ efficiency rating, such as PC Power and Cooling, Seasonic, Corsair and Antec Earthwatts (Seasonic actually makes them, here's an example: http://www.hardwaresecrets.com/article/526/1).

Just finished WOT 12 last week.

Actually, the graphics board upgrade was purchase by my #2 son, a heavy gamer. Seemed like a good idea at the time. Turned out the system he uses was not up to the job as it did not have a PCI Express slot. It has Althon 64. So instead I agreed to swap him with another more recent system that does have a PCI Express slot, with an Intel 820D (early dual core), as that system is pretty much surplused at this point anyway.

So the board goes in and runs, but so far we have not converted the system to his use. (Just need to set the time for the clean install process.) He does sometimes play continuously, so puts the system to definite heavy duty use. However, he probably stays away from the most demanding games due to the limitations of his current system (the Althon 64).

Just not that happy with having to now upgrade the PS too. Any harm in just "letting it rip and seeing what happens?"

I found out that WOT has a finale - wow, that was some long wait!

>Any harm in just "letting it rip and seeing what happens?"

Do you know what power supply you have and how much it outputs?  A 4770 can beat out a 4850 in many games, yet use less power: http://www.tomshardware.com/reviews/radeon-hd-4770,2281-13.html  If it has a high current on the +12v line, it may work fine.

I'm running an HD4850 with an Athlon64 X2 3800+ and it handles mosts games fine.

I opened the box to take a look at the power supply. It is a XION 450W model XON-450P01N. Now that I think about it, I believe this is a replacement that I put in not too long ago.

While I had the box open, I "temporarily" pulled off the power from the CD drive and connected the other one for the ASUS. I hardly ever have any use for the CD drive anyways as there is also a DVD drive. About the only use would be to copy a CD from one to the other, which I don't do.

Hmm, i am inclined to try it for a while. If we saw crashes, i suppose that would be a telltale sign, but if no crashes, probably ok.

Do you agree?

Ok, will probably go for that and see what happens.

Lot of work ahead, as I need to reburn the two machines, plus while I am at it, I will probably create a set of new VMs in VMWare, as may as well have a "fiesta of system installations."

Thanks for your help. Several points of view, while conflicting have been valuable, so splitting points.
