What make PSU?

The current psu was 1200W

Though i'm hoping to get a smaller one if possible to save some money.

I used one of the calculators from Admiral Huddys link in another thread and it tells me i only need 500W.

I'll need to look into the gfx card requirements, ive no idea what it is at the moment.

This is the spec:

• Intel Skulltrail, i5400 Express 771x2 PCI-E (x16) DDR2 ECC/Non-ECC 800MHz, SATA II, SATA RAID, E-ATX
• 8 gig ram
• 2 x Intel Xeon Quad E5420 @ 2.5GHz
• 2 x Zalman CNPS9500A-LED CPU Cooler
• Sapphire ATI Radeon HD 5870 1024MB GDDR5 PCI-Express Graphics Card
• 2 x Samsung SpinPoint F1 750GB SATA-II 32MB Cache
• Sony NEC Optiarc AD-7200S 20x DVD±RW SATA Dual Layer ReWriter
• Lian Li PC-A71B Aluminium Tower Case - Black
• Creative Sound Blaster X-Fi Xtreme Music 7.1 Sound Card
• Microsoft Windows Vista Ultimate SP1 64-Bit
• SST 1200W SST-DA1200 MODULAR PSU

A smaller psu won't actually save you money
The computer will only draw the power it needs. So ur pc will be using the same power regardless of the size of psu

However what will make a difference is the psu efficeny. The more efficent it us the the less power needed to supply the same load
 
For those on about the second CPU being idle, it gets used every day to it's max. I freelance doing 3d modelling and visualisations in which the number if cores you have makes a big difference to the speed of your renders. Try doing an animation on a quad core and it will drive you up the wall.
 
One more quick question.

When you get a new psu can you use all the same cables you used before or would you have to use the cables that come with the new psu?
