Bought a new video card today...

Thanks Huub and Roger,

missed your answer yesterday. I'll check what I can do to make some improvements.
I know my processor will remain the bottleneck, but this way i can improve my system in bits, nd go for the new MoBo and processor during the next year.

R.

I would go for at least 700W. For my new PC I will have a Scythe Chouriki 2 850W. It will cost you around € 110,-. But it should be a very silent powerful power supply.

Roger said:
Yep Huub's right Rob; a minimum 700W is best as current transients can be very high dragging the volts down. Mine is 700W.

It'd be wiser to invest in an 80+ (efficiency rating) PSU with 600W at best (anything more is for servers or SLI setups) than to go for a ridiculously high powered ineffective one.

Kind of like getting 150 hp out of a 5 l V8 versus 250 hp out of a turbocharged 2 l inline four...

When I need to get a new mobo, any suggestions for a LGA775 board with good OC capabilities?

Depeding on budget, go either for a P45 or X48 board. They come in DDR2 and DDR3 flavors.

If you have a quad core CPU, a P45 it is, as this chipset clocks better in the FSB department compared to the X48s.

Well Bjorn as it seems we're ignorant (compared to you) as to the relative efficiencies of the switched mode power supplies on the market, perhaps you could suggest a manufacturer and model number at a reasonable price that would handle high transient currents at a 600W rating?

Well, I for one am very content with my Coolermaster RealPower M520. An excellent bang for the buck for my S775 rig and undoubtably just as well suited for non-SLI/CrossFire i5/7 systems.

Well actually all of our testing at TechCorp indicates that good power supplies only draw the wattage necessary to power the unit's demands so if you have a 700W unit and your unit only requires 400W the rest is simply reserve and nothing is wasted. Bjoern you are basing your assumption on what you have experienced rather than factual data. While I do agree it is better to be conservative on your power supply purchase using a configurator, it is still wise to have extra power available for upgrades.

Yep, I've always advised system builders to "spec up" their PSU. It makes sense as you can bring it from one system to another when eventually upgrading. I've a Thermaltake Toughpower 1200watt unit in my main pc which has served me well since I built the rig. It'll be more than adequate for when I [LINESTRIKE]am let [/LINESTRIKE]decide to build a new system. :)

I was demanded to spill out a recommendation so I spilt out a recommendation based on experience.

You can read yourself to death about PSUs. I did that before choosing the Real Power M, but as this was two years ago much of the information has been already overwritten.

I don't need excess power, so why waste tons of money for a 3453434589 W PSU?

sounds like a personal choice allow others to do the same!
 
When it comes to PSU's I have a few simple rules.

Never buy off-brand or no-name units, always buy the ones with good reputations.

Never buy a PSU at the minimum rated wattage for your application, it limits future upgrades, overclocking and the PSU will wear out faster. As to how much over the minimums to go is a personal matter, but 100 watts buys a good amount of head room.

Never buy a PSU at the minimum rated 12v amps for application. This can severely restrict your capabilities with drives and video cards.
 
My Real Power Coolermaster PSU went bang last year. One of the loudest bangs I've ever heard.

I replaced it with a HX1000W Corsair Modular PSU which has been a dream ever since.

I will stick to Coolermaster cases but Corsair PSU's from now on.

Working in a small tech repair room for a large well known computer manufacturer a couple of years ago made me immune to the sound of exploding power supplies. :d

It was like a gunshot about a meter away from my left ear. When I took the PSU out there wasn't a mark on it anywhere but it smelt completely burnt :angryfir:
