Help me to get a proper rated PSU

Castout · 03-02-11, 05:07 PM

I'm going to buy a few components which I haven't changed since my last new build.

In the end the system will be

Intel i7 2600 CPU
NVidia GTX 560 Ti
6 Gb DDR3 RAM
1 Tb HDD 7200rpm
1 DVD-RW optical drive
Gigabyte Ultra Durable 3 motherboard
1 External HDD to power from time to time
1 Mic and headphone to power

And I'm thinking to get a 850 Watt good PSU. Would that be good enough?

Should I get an additional 2Gb DDR3 RAM?

i believe 600w should be more than enough

That ^. I got a 750W just because it was the same price than their 600W.

And 6 or 8 GB RAM depends on whether your mainboard supports dual or triple channel.

Thanks My mobo supports dual channel. So does that mean I'm better off with even number of RAM stick?

As for the PSU I always aim a tad high because you need to put in the power factor of 0.8 and I'd like a stable power fed in. Higher power rating usually mean longer lasting PSU in general to my understanding.

I had had a horrible experience where my GPU was fried because the PSU failed. I was advised then to buy a local PSU and though it was rated a 700+W PSU it failed after 2 weeks. The main culprit was the total war game I played. So I only buy proper well known PSU now and with higher rating than what I need.

Dual channel always: 2x or 4x RAM-Bar. These today have 2 or 4 GB per bar.

So with dual channel you either have 4, 8 or 16 RAM

RAM is cheap. Take 8 GB, therefore. I planned for 4 initially, but now I'm happy I did not make that a gospel. I took 8.

Yeah I will add another stick to make it 8.

It seems I have been mistaken about the CPU. I will be getting either i7 880 or i7 875K. It's the socket.
picked me a LGA1156 mobo and I didn't know better.

I can live with either i7 875K or 880. I assume 880 price has come down to reasonable value. If not I'll settle with 875K.
