20pin psu on 24pin mobo (P5B Deluxe)?

post #1 of 11
Thread Starter 
Putting together my new system (P5B Dlx, e6600) last night I realised that my old psu only has the 20pin atx mobo connector. It's an Antec Truepower 430. Can I simply use a 20-24pin adapter safely?

I've made a scout run to the nearby Frys in case I need a new psu. Recommendations appreciated!

Here are the options:

Antec 550 Truepower TRIO 550w - $120
Antec NeoHE 500w - $110
Coolermaster Extreme Power 600w - $90
Thermaltake Purepower 500w - $70

I'll be running a XFX 7950GT, two sata drives, 1 dvd-r and doing some conservative overclocking (hopefully).


Thanks,
Mitch

As with any PC hardware, you want to try not to use adapters. In this case, a 20-24 pin adapter doesn't really do anything.

And actually, a 20 pin ATX plug will go into 24 pin motherboard safely. The extra 4 pins are for SLI really. And you won't be running it, so I don't think you need an adapter or new PSU.

Antec and CoolerMaster are crap in my book, so here's what I suggest:

-Enermax Liberty $120.

- FSP Group $97.

- Thermaltake $104.

Otherwise, the PC Power & Cooling Silencer 610W for $170.

The adapter is really not necessary. You don't get any more power from the adapter because it's just splitting lines, as opposed to dedicated lines. It really doesn't matter, but the adapter isn't necessary for operation.

I thought that the other 4 pins supply more current to the MB in a situation like SLI...

But about 550W would be the best for this system. 430W is kinda weak.

If the store has OCZ, Tagan or Seasonic check them out

Of the brands you listed I would choose Antec.........had no issues with my 3 Trueblue 480's.......but it's been said that recent Antec quality has been patchy.

That's a very good PSU. 2 12v rails at 18A each is nice. I would recommend a little more wattage, but I think it would run your rig just fine. Mine runs off of a 460W with 30A@12v with no problems at all.

The only thing about that is it has 2 80mm fans. It *could* be loud, but the reviews say otherwise. If you has the choice, I would recommend something with a 120mm fan.
