Default PSU Question

I just happened to notice that the PSU I planned on buying for my rig (Cooler Master RS-450-ALCY) doesn't have PCI-E support. I'm getting a PCI-E system (DFI board with 6800GT). Do I need "PCI-E support?" Or is that only required for cards that suck down extra juice and need a direct power link?

My other choice is the Antec NeoPower 480, which does have PCI-E suport. However, it costs $35 more until the rebate check comes.


...n00b question... oh well :P.

Definitely most pci-e cards need that.

Good thing you made this because I had no idea PCI-E cards needed PSUs that support it

Oh riiiiight. Now it all makes sense. In my mind I wasn't connecting those extra four pins to PCI-E. I've heard the DFI board I'm getting is tempermental with the adapter so I'll just get the Antec. The Antec has a more acurate 12v anyway, plus 30 more watts... even though it is less energy efficient.

Thanks for the replies.

So if I wanted this mobo and this PSU, I would need to buy a 24pin-20pin adapter?

First things first...that PSU SUCKS!!!! Only get brand names such as antec, thermaltake, ennermax, PCP&C and OCZ. Everything else sucks.

You could get a 20/24 pin adapter, or u could just get an antec neo power or an OCZ Mod/Power stream. You will also be better off with the DFI Lanparty nForce 4 Ultra-D mobo

If you are buying entirely new and are getting a PCI-E board, get a 24 pin ATX2.0 compliant power supply. A 20 to 24 pin power adapter still poses a problem as the the 12+v pin still gets toasty and can burn in many cases.

You can use a 20 pin PSU with an ATX2.0 motherboard, but I would advise against it.

DO NOT use a 20 to 24 pin adapter, especially with a DFI board. Get this PSU:

Silverstone is the best brand you can get, not counting PCP&C. Just look at it's specs. I am not judging it off the specs alone, read some professional reviews on the PSU.
