Motherboard 8 pin connector...

i was thinking about getting this motherboard but it has the 24pin power connector plus the 8pin power cpu connector. The powersupply i have doesnt have the 8 pin connector. is that needed?

Well there's no way around it ... if you use that board you will have to upgrade the psu or it wont even blink from post

[rubberman]

let me ask you another question since it looks like your an AMD guy.

which cpu since they are similar in speed ratings:
-athlon II x3 425
-athlon II x3 435
-Phenom II x3 720

[wingnut2003]

if you could get a spec on the board for what the voltages are for the 8 pin connection, you maybe able to get a adapter plug to work with it, or make your own. just a suggestion.

[aedipuss]

wingnut - you should check the quote in your sig. it makes no sense. hurst is a type of shifter for a car. were you trying to spell "hearse"?

Most of those will accept the four-pin standard connector and boot just fine. Not certain if its the same model, but just did this on a very similar Gigabyte board.

If it specifies the 8 pin requirement for the purpose of warranty ... once out of warranty you can play all you like with the setup ... so it's not worth the risk

In respect to the cpu choices there's not too much between them apart from the amount on on die cache memory

If you into hard core gaming then my money would go on the "Phenom II x3 720" having 6mb cache total ... this really gives the system a major boost over the previous cpu choices listed

As for athlon ... I thought this was extinct, lol ... well the re-carnation ... the "athlon II x3 435" run around 200mhz over the previous listed cpu ... but in reality there's not much to gain ... there is a small cache memory difference again but not enough to justify when used in real world ... the user wont even notice the difference

The only problem is the FSB at the cpu core is still using a multiplier @200mhz ... a bottle neck when considering the memory now runs above 1000mhz ... ddr2 @1066 and ddr3 @1333mhz

I recall the days going through 66, 100, 133, 166, 200, 333mhz ... and a few others ... the faster the FSB for both cpu and memory the better when performing any video conversion process

Beware cpu's come in different versions ... with amd "Black" normally refers to an unlocked multiplier but the board must support some form of overclocking ability

True , I prefer AMD over INTEL but my system specs say intel ... my old amd systems are still running ... athlons of course

I've used 4 to 8 pinn adaptors and they work. newegg carries a couple of types. The board might run with a 4-pin power supply connector but in my expienence you won't be able to overclock. 8 pin power supplies don't have to expensive,I've bought them for as little as $25 on sale. You can certainly find one for $40-50.

[budz]

Most newer power supplies come with 4/8 pin. It's older power supplies that lack the 8pin. The OP can also buy a 4pin/8 pin adapter for the ps.

Is that the EPS12v connection? Aren't most PSUs these days EPS12v compatible? I've been dealing with that connector for years now, but I've always had EPS12v PSUs. An adapter might be the way to go, just keep in mind that the idea of the extra connector is to supply more juice to the board so make sure your PSU is up to the upgrade. That's probably the most important component in your case and you don't really want to skimp. Don't buy simply based on the rated wattage of the PSU either, there are several other important factors to consider like 12v amperage, PFC, etc. That said you should still be able to find a decent PSU for under $100.

Quad Core processors require the 8 pin connector or else they won't boot.

Dual Core require 4 pin connector.

Looks like the Triple Core can use a 4 pin connector.

4 to 8 pin adapters do not work for CPUs that require the 8pin because you do not have the proper voltage.

When all else fails read the documentation for the motherboard and CPU.

I'd have to go back and look up the exact model but the AMD quad-core on the Gigabyte board is booting just fine with the 4-pin connector.

[usually_quiet]

My MATX motherboard's specs say it supports all Athlon II x4 processors, plus some Phenom II x4 processors, and it has a 4-pin connector. More of the ATX motherboards I saw when I was shopping had 8-pin connectors, but I understood it was needed to power multiple graphics cards, not the CPU.

Beg to differ Bjs

AMD's Hypertransport is not a "bottleneck" for any memory, while it has a base clock of 200Mhz it performs several operations per clock cycle to achieve its rated bandwith the SAME way DDR2 and DDR3 achieve their rated speeds by using a base clock of 200Mhz and a multiplier

The day is gone when psus supply voltage to the cpu or memory directly, the 4pin and 8pin connectors simply provide 12v power to the mobo power supply which transforms the 12v voltage to the voltage the cpu and memory and everything else on the mobo need, except 5v which powers the usb

Or did you mean that 8-pin connectors require more current? which would also be an assumption
