How many watts for PSU

This is my proposed build:

CPU: AMD FX-8120 3.1GHz 8-Core Processor
Motherboard: Asus M5A97 R2.0 ATX AM3+ Motherboard
Memory: Corsair XMS3 8GB (2 x 4GB) DDR3-1600 Memory
Storage: Seagate Barracuda 1TB 3.5" 7200RPM Internal Hard Drive
Video Card: Asus GeForce GT 610 2GB Video Card
Video Card: EVGA GTX 650 Ti 2GB

I would like to know if a 500w PSU would be enough (or if I could go as low as 430w).

Or will I need a larger one? Is 750w overkill. The only future upgrades would possible be a few HDDs and an SSD. I might add another 650 ti in the distant future, but probably not. I would like it to be quite future-proof for any other possible upgrades.

It will need to cope with being on for up to 10+ hours a day (only occasionally). I will be doing medium/heavy gaming, plus some minor video editing. (also the quieter the better)

So could anyone please suggest a suitable PSU? My budget is about £60 ABSOLUTE MAXIMUM (if possible). And modular would be good, but semi-modular is fine.

(I am in the UK by the way)

Thanks in advance

As I've said in one of my relies above:

The GeForce GTX 650 Ti does not support SLI mode. If you add another GeForce GTX 650 Ti in the future it can only be used as an independent card with another monitor connected to it.

You would need to start with at least a GeForce GTX 650 Ti BOOST edition card if you're planning to add a second one in 2-way SLI mode in the future.

There is plenty of spare capacity to handle extra HDDs, SSDs, add-in cards like sound card and network interface cards.

500 watt is more than enough for your system..
Even if you're overclocking..

Seasonic 520W M12II-520 80 Plus (Bronze) or Super Flower SF-550P14HE Amptac (Bronze) is a excellent modular PSU..

but if you're stick with that GT610 card, antec VP 450 (450watt psu) is enough to deliver juice..
about antec VP450, read review here => http://www.hardwaresecrets.com/article/Antec-VP450-Power-Supply-Review/1487

btw, why you choose 8150? the new piledriver FX 8320/8350 is significantly faster than that bulldozer version..

The GeForce GTX 650 Ti does not support SLI mode. If you add another GeForce GTX 650 Ti in the future it can only be used as an independent card with another monitor connected to it.

For a system using a single GeForce GTX 650 Ti graphics card NVIDIA specifies a minimum of a 400 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 20 Amps or greater and that has at least one 6-pin PCI Express supplementary power connector.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Total Combined Continuous Power/Current Available on the +12V Rail(s) rated @ 45°C - 50°C ambient temperature, is the most important factor.

Overclocking of the CPU and/or GPU(s) will require an additional increase to the maximum combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock being attempted.

The Antec Neo Eco 520 Watt (0-761345-285209) Modular PSU, with its maximum combined +12 Volt continuous current rating of 40 Amps and with one 6-pin and one (6+2)-pin PCI Express supplementary power connectors, is way more than sufficient to power your system configuration with a single GeForce GTX 650 Ti graphics card.

Antec Neo Eco 520W Modular PSU 80Plus Bronze uses Seasonic as its OEM for £38.52 Ex VAT (£46.22 Inc VAT)

The site you gave me didn't inclde any modular cables :(

What about this one?? http://www.amazon.co.uk/Corsair-Builder-Series-Modular-Certified/dp/B00ALK1GFC/ref=sr_1_1?s=computers&ie=UTF8&qid=1368120432&sr=1-1&keywords=antec+psu+modular

Sorry. Antec tends to leave out power cord and modular cables in their ECO series models that don't have the C suffix in their model number. This is for users that are replacing an existing PSU.

The Corsair CX Series Modular CX500M (SKU# 75-002017 / CP-9020059) power supply, with its maximum combined +12 Volt continuous current rating of 38 Amps and with two (6+2)-pin PCI Express supplementary power connectors, is way more than sufficient to power your system configuration with a single GeForce GTX 650 Ti graphics card.

So will it be good for intensive tasks like gaming, and is there room to upgrade components in the future? (Extra HDDs, SSD, extra GPU etc.)
