okay so i am about to build a computer but i don't know what watt PSU to get my specs are as follows;

Case: antec nine hundred two

CPU: Intel core i5 2500K

CPU cooler: Thermaltake Frio

Motherboard: Asus p8z68 pro

Memory: 4gb (2x2gb) corsair ddr3

Video card: Two ATI Radeon HD 6870's in crossfire

Hard drive: Western digital 1TB 7200 rpm

Drive: LG DVDRW drive

Sound: Asus Xonar 24

MUST BE MODULAR


So what watt PSU do you think i need? also what do you think of my specs?

P.S Under £100 please


Thanks in advance:);):)
 
Looking at this - I would go for at least a 550W good quality PSU.

Since you are running two cards then a 650W PSU wouldn't be a bad idea as it gives you some headroom. A nice unit like this would a good plan and it is currently on for a great price.

If you are looking for a modular unit then one of the XFX Black edition range would be a great idea (as mentioned by chuggerboom and RJC), these are also really nice PSUs (here is a review).

As for you spec, it looks great. Though I would only go with the Z68 board if you are going to use the new features (compared to a cheaper P67 board).

Aye, it does - but so do much cheaper P67 board like this one.

P67 boards like this also do CPU overclocking and multi-GPUs (SLI/CF) just as well as Z68 boards.

The main benefits of Z68 boards are:

- SSD caching
- Intel Quick Sync
- Access to the onboard GPU

If you won't be using any of these features much then you may as well go for a P67 board and spend the money on a pair of HD 6950 1GB cards instead of 6870s.

Excellent monitor, really good choice.


As for the sound card question, what speakers/headphones will you be using?

Right now im thinking logitech x-530 speakers but that decision is really based more of the price than anything else i dont really care about 5.1 so if any one has any suggestion for 2.1 speakers that are competitively priced then there welcome. I will also be using Razer Carcharias headset when playing online
 
In that case a decent sound card wouldn't be a bad idea. Something like the Xonar DS or DX would be my recommendation.

At their current price on OCUK the X-540s are worth a look.
