I think that this is the best you can do with that price range http://uk.pcpartpicker.com/p/2eqDw

However I'd strongly advise you not to go cheap with the PSU, especially not when having k-version CPU and powerful card such as 290x.

Hi,

Thanks for both of your answers but should I go with this? http://uk.pcpartpicker.com/part/antec-power-supply-ea650platinum (what Foldalot suggested)

If you can afford it , buy it , it's a top notch PSU.

ko888 · Dec 3, 2013

For a system using a single AMD Reference Design Radeon R9 290X graphics card AMD specifies a minimum of a 750 Watt or greater system power supply. The power supply should also have a maximum combined +12 Volt continuous current rating of 42 Amps or greater and have at least one 6-pin and one 8-pin PCI Express supplementary power connectors.

For a system using two Radeon AMD Reference Design R9 290X graphics cards in 2-way CrossFireX mode AMD specifies a minimum of an 1000 Watt or greater system power supply. The power supply should also have a maximum combined +12 Volt continuous current rating of 68 Amps or greater and have at least two 6-pin and two 8-pin PCI Express supplementary power connectors.

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

Overclocking of the CPU and/or GPU(s) may 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 EVGA 600B (100-B1-0600-KR) is NOT Haswell ready (according to Intel's testing procedure). Neither is the Corsair CX600 or CX600M.

Thanks for all the help and nice post ko888, very informative.

Thank you Blackbird, but will this also handle overclocks ? because I wanted to overclock my CPU to about 4.3ghz and more later on. Also I may overclock my RAM.

Thanks

Dark Lord of Tech · Dec 3, 2013

Yes it will.

Hi,

What about this? http://www.ebay.co.uk/itm/Cooler-Master-Gx-Lite-700W-86-Single-12V-Rail-Power-Supply-PSU-RS700-ASABL3-UK-/380772597755?pt=UK_Computing_PowerSupplies_EH&clk_rvr_id=556045608494

Thanks

Spov :

That's leftover product since Cooler Master has actually discontinued the GX-Lite Series.

Hi,

Is this OCZ ZS Series 650W Power Supply 80 Plus Bronze a good psu ?

Regards

ko888 · Dec 4, 2013

Spov :

OCZ is now under Chapter 11 Bankruptcy. There's no mention of what's going to happen with their PSU division or how long warranty service will still be available. Their SSD business has already been sold to Toshiba.

Spov · Dec 4, 2013

Hi ko888,

Thanks again

. So what psu do you recommend ?

Regards

ko888 · Dec 4, 2013

Spov :

I prefer recommending PSUs that use Seasonic as the OEM or an actual Seasonic branded PSU because I know they are actually able to deliver the power output specified on their label and professional test reviews support it.

Some of Antec's, Corsair's, Cooler Master VS Series, NZXT and all XFX models are made by Seasonic.

I've already recommended http://uk.pcpartpicker.com/part/xfx-power-supply-p1650snlb9

Hi ko888,
