Hi, I'm new to this board and would like to start posting with a question.
I was planning on buying a DFI NF4 Mobo and came across the statement that you absolutely have to own atleast a 480 W power. I own a Sirtec 420W power which i bought a year ago. So is it insufficient ? I'm asking because a new power doesn't really fit in my budget. Have to go with a different motherboard in that case..

Here is the rest of the rig i was planning on buying, any thoughts?

DFI LANPARTY UT nF4 Ultra-D
A64 3500+ venice
XFX GF 7800 GTX PCI-E 256MB VIVO EXTREME EDITION
2x1gb Buffalo DDR 400 CL3 or OCZ 2 GB DDR-400 Kit Platinum EL
SAMSUNG 160GB DMA/133 7200 RPM 8MB
Antec SLK3000B/MD
Sirtec 420 W

If I get the money, then i go with the more expensive OCZ memory. But is the buffalo memory ok for gaming purpose? Some oc'ing is expected, but I will propably have to use a divider?

Your configuration is very very good (7800gtx,2gb of ram.::!)...so I advise you to buy a good psu (ex. ocz, tagan, enermax...with at least 480W-530W)....
The psu is very important for a stable pc and for oc...
So have an other "sacrifice", and buy a decent ATX 2.01 psu for optimal power :)

power supplies are really important dont cheap on anything that runs ur pc cuz itl suck in tha end i recommend either gettin 1gb of ram or downgrading cpu to 3200 or 3000 and overclockin past 3500+ then use tha saved money for a better psu...
just my opinion ...but ur rig sounds good , good luck

Man, it's really hard to decide what to sacrifice :( Maybe 1gb of ram is sufficient for now, but which of these two options is better? Buying 2x512 of ram and getting another set later on, or buying only one 1gb stick and getting another later? Is the performance gain from dual channel noticable in games? I heard it's hard getting 4x512 to work properly..

Any comments on these ?

GEIL DIMM 1 GB DDR-400 Kit Ultra-X Series CL2 2-2-5

OCZ 1 GB DDR-400 Kit CL 2-3-3 performance (20 euros cheaper than GEIL)

Tagan TG530-U22 2force 530 Watt 240 Watt Combined, 2x PCIe, 1x AGP

Yup new PSU time. If you ever have any probs with your system the first thing nayone here will say is upgrade the PSUas it's not in the recommended list. The recommended list for the DFI nf4 mobos *has* to e followed unlike the usual recommended hardware lists you see sometimes. THe lists here are required and not just recommendations.

See the PSU thread, but OCZ, Enermax and PCP&P are the best. Alas that will take a fair chunk out of your budget.

Tagans are nice, basicallu OCZ PSU's at the end of the day as they are made by the same people. Good choice for £/performance.

Forton Bluestorm 500 Watt is even cheaper, and was in the recommended section. This will do.. So anyone have some comments on memory?

I'm starting to wonder if it's really worth for me to buy a DFI mobo, if I buy say an Asus A8N-E and keep my old PSU, which is sufficient for that motherboard. The cost will be about 180 dollars less. And thats a lot in my opinion. What do you guys think?

DFI is only recommending 480W to be on the safe (overkill) marginal side.
Any _quality_ ATX12V 2.x compliant power supply with about 25A on +12V (and about 350W) should be enough.

Make sure any power supply you select comes from this thread.

is this your current PSU http://www.extremeov...wer_420W_1.html

if so then this will not be suffcient for any NF4 board nevermind the DFI as the rails do not have enough amps, i ran mine for a few months with a 450w PSU but it had sufficient amps on all rails, ran flawlessly i only upgraded to the Hiper to ensure i have no problems.

Yeah that's the one i've got. Well that settles it then, going with the Fortron bluestorm 500 watt and DFI.
Now I just have to figure out where to get the funds. What do you think of these two options?

1. Get 2 Gigs of memory (2x1gb DDR-400 CL3) and a venice 3000+ and overclock it, even though the memory doesn't overclock well. Dividers will help me here?

2 Get 2x512 of memory(better quality) and a venice 3500+

In both cases I save enough money to buy the PSU. The computer will be used for gaming.
