The Enermax 550W is also a rather good PSU. Has a 36amp 12v rail so can power a lot of stuff with no impact at all...

I get just short of 5700 on my setup.

Thanks Sith et all - I installed 66.81 and got it up to 4446 now i'm thinking of changing my puny 280w power supply to something a bit more substantial, do you think it would help?

Cheers

Don't think changing the PSU will help.

You can also overclock and optermise settings as Alex has done. But if you start uping the voltages etc then you will want a better PSU.

 

Sammy - TBH, the stock GT speeds will get you circa 4500-4600 on a system with a reasonable CPU (although CPU speed barely effects 3Dmark05, it does give you a few more points it seems - proven by o/c'ing the CPU on mine).

Its worth having a good PSU on these systems, if for nothing else but stability.

Emermax Noisetaker is a good PSU, the Antec (true blue / neo power / true power) ones seem very good too, as do the OCZ ones alledgedly (I say this because so far, I've yet to be convinced).

TBH anything > 400W will be more than sufficient unless you are running hundreds of devices (HD, DVDR etc..). You are running a GT right (sorry if you've already stated that).

 

The only GFX card based benefit from a good PSU *can* be better GPU overclocks due to more stable power rails (i've proved that).

 

PPS.. note I've not up'd the GT's voltage (still at stock) the Ultras run 1.4v i *think* and GT's 1.3v... but I noticed the core clock could be taken higher with a more stable PSU.

I have up'd the voltage of the CPU thou, VCORE, to cope with the additional strain of more Mhz (via FSB / multiplier settings).
