It depends on the PSU, but even a quality 350-400W power supply would be plenty.

 

Are you shopping for a PSU right now?  Where can you order from?

 

How much can you spend on the PSU?

Hi, The cheapest Modular PSU around that wattage i could find was a 680W be quiet Power supply. it gets good reviews and is from aria so it ships to the UK.

Like TwoCables said thought, you don't need 750W for you system unless you are going to upgrade.

Link Although it is 95.56

based on the motherboard and chip that you have chosen - you might be tempted to upgrade to a high-end gpu or two someday, then i suggest get a quality 750w now.

Alright.  :)  Here are a bunch of modular PSUs from Scan.co.uk starting at 520W (I'm taking into account future upgrades):

 

 

 

Any of these are good, but of course the available connectors that each of them has can make or break the deal.  If it were my money, then it would be a toss-up for me between the Corsair TX550M, 520W SeaSonic M12II, and the 620W Antec High Current Gamer M Series.  The reason is that all 3 of them have two PCI-E connectors:  the Corsair and the Antec both have two 6+2 pin PCI-E connectors but are only partially modular PSUs.  The SeaSonic is mostly modular which I would personally prefer (only the necessary cables that everyone needs are hardwired), but instead of having two 6+2 PCI-E cables, it has one 6-pin and one 6+2 pin.  So the only problem there would be if two 8-pin PCI-E cables are required;  it would mean you'd have to use those ugly molex adapters.  :)

 

Although, the NZXT HALE82 has four PCI-E connectors:  two 6-pin, and two 6+2 pin.  :)

 

In other words, it's all up to you and what you feel you may need or want.
