All I want is a reliable, not too costly, reasonably efficient, low wattage PSU.

All I get are either crap, or 60 000 watts at R 10 000 per watt with 5% efficiency at 50 watts.

I just want to run a simple PC with maybe the option of installing a low end graphics card at some point. Why can't I find a reliable PSU? WHY?????

Also, what size graphics card would I need for smooth playback of 28Mbps AVC video files and maybe some cutting and joining?

Thanks.
 
Yes, Corsair is a good choice.
As to a graphics card... what motherboard and processor do you have? I know the 2500k and 2600k (i5 and i7) have a decent graphics processor that you can use if you make use of the onboard graphics.

It's an office machine, so every hour of downtime is extremely costly. Having said that I don't want to waste money. So, no budget, but as cheap as possible for maximum reliability.

From Rebel Tech for R 442? But the fan seems to be in the wrong place - there's no holes in the top of the box.
 
You can use that power supply and just turn it upside down.

Higher-end cases have the PSU's mounted at the bottom and from there you have two options:
Fan-up, so it uses the inside of the chassis as an air intake
Fan-down, so it uses the bottom intake (grill at the bottom of the chassis) as an air intake.

I've tried it on my Q9550 and i3 2100T, but not the machine that it needs to work on; that's an i5 661.

You should be able to manage with any low-end graphics card. Something in the range of R1000 should work acceptably.
 
Why not get an Amd F1 motherboard? Get a good F1 processor and gpu combo, problems solved. It is designed as a general use system.

Ah, I don't have much experience with high end cases.

You think that PSU will run for a good few years? I'm not used to replacing PSUs, most of mine have lasted 10 years easy.

What about the cheapest one they've got? R 337? It's got no fan, which is nice.

Oh ja, how loud do you think that PSU will be?

Take that one. Just turn it upside down.

I have two Corsair PSU's. A TX750 and a VX450. The VX450 is pretty darn silent so you probably won't hear it. The CX has a 3 year warranty but it should have no problem running for 5 years in an office environment.

As to the gfx, what gfx is it? I don't know how the low-end ones perform.

The specs say this:

Sapphire HD5450, 1GB 64bit DDR3, HDMi ready , Silent heatsink only + extra Low-profile pci bracket , DirectX 11 , built-in HDMi codec+7.1 audio , pci-e 2.0 x16 ,RoPs : 4 , 12.8GB/sec memory transfer , 80 stream processors ( pixel shader engine + vertex pipelines ) , core/memory : 650/1333mhz , dvi+d-sub+hdmi , HDMi+HDTV-out - retail pack

I have absolutely no idea what most of that means. The reviews on newegg are generally positive.

Edit: do you think I should push the PCs RAM to 16GB? the movies are about 200MB/minute.
 
Thanks okes. I'll leave the graphics card till they tell me they want to do editing. Ordered the CX430.
