Where to get nice cases...

[GilesGuthrie]

It'll bump the cost of the build up by £50-£60 but i guess it's better to be safe than sorry. Thanks.

My last self-build blew three power supplies. My new system has a 1000W PSU. This isn't a hypothetical lesson you're getting from me!

What......a computer?

Errr... No, What do you think this thread is about? Just computers? It's about cases and that's what I meant.

A good 400W should be enough for your setup.

You sure that's enough?

 

[ROAD_DOGG33J]

It most likely would be. Though I guess a 500W would be a bit more on the safe side. If it's a quality power supply, it should be able to provide about 100 watts or so over the rated output.

No way in hell is a 400W PSU enough for a 5770 (Hell, they recommend 450 on the ATi site). You're wanting a 600 at least, half decent branded.

Which means that less is OK, since they tend to go on the safe side. They probably had to factor in the most power hungry CPU out there. I would say that a quality 500W is enough for this setup if there are no substantial upgrades planned. That should be provide for the best efficiency.

Here's a quote from overclock.net

i run a 620w with my quad - and have run dual 4870s nad dual 3870s both highly overlcocked (along with the quad) with no issues.....

And that's an AMD processor(more power hungry). Granted the PSU is a Corsair, but that's what happens when you have quality.

With PSU's you don't want to be on the safe side.

There is a lot more to PSU's than Wattage as well, especially if you're running dual GPUs, you really have to look at rail configuration and amperage, perhaps even more than wattage.

The Cosair is probably a HX620 which is an excellent PSU, and is probably something more like he should go for.

 

[ROAD_DOGG33J]

Using this calculator I'm getting 365 watts recommended with:
a Q8200
HD5870
3 sticks of RAM
2 HDDs
1 DVD writer
2 USB devices + 3 fans

And that's at 100% TDP and 100% system load and capacitor aging at 10%, which isn't that much of a factor. Under regular use, not benchmarking, a computer will never load all components 100%.

Any quality PSU will have enough amperage for a CPU and one good video card.

Looks like we're going to go for this baby which should be plenty.

The annoying thing is, Novatech's own brand PSU's are less than half the price for the same power output, but even Novatech's sales advisors told me that was a bad idea!

Are they really that much worse?!!

 

[GilesGuthrie]

Good choice.

If when you're mounting it in the case, the PSU's fan is blowing directly into the roof/floor of the case, don't be afraid to turn it around. The mounts have rotational symmetry.

Thanks for all the help guys. I have built the PC and am about to create a thread for it.
