Does this GPU require external power?



I am currently in the middle of designing a PC for my Dad.

He doesn't require too much graphics power but he wants more than a 6450.

I have chosen a Sapphire HD Radeon 6670 (

but I do not know whether it requires direct power from the PSU (as the PSU is a fairly basic one

I would usually go with a more reputable brand of power supply but this one although cheap has 9.1/10 from 37 reviews on eBuyer, and my Dad's budget is only around £300/£320 Max.



that 6670 workd fine without external power. As for the psu, it should be fine for your needs.

 For all that is holy, please don't get that PSU. Bottom-line, get a Rosewill Capstone 450, or something that at least has a reasonable ripple and efficiency! I wouldn't be surprised if that PSU blew within a month.

Holy crap a £12 house burining psu!!

Buy one of these 


According to PCPartpicker the system will only require 185 Watts, so I presume although it is cheap, the good reviews and the 600W approximation, that it'd be fine for a very low end PC. This isn't build for gaming, just light web browsing.

Although if I did get an APU (AMD A8 5600k/A6 5400K) Then it would leave some spare money for a Corsair CX 430M etc

The reviews on that psu are fake or idiots.

David score 10 "Well worth the mony"  allen score 8 "Cheap-does the job Slightly noisy"

+ a 600w psu that dosent even have a pcie connector is a joke and will damage your computer or blow its self up or give the computer a consistent wave of dirty power slowly killing off your computers components.

The psu is one thing you never cheap out on however cheap you are biulding.


Haha fair enough. I have a Corsair CX 430 in my PC so I'll probably get a CX-430 Semi Modular. Same price.

Here a £300 pc that will be perfect for web browsing and hd video

CPU: AMD A8-5600K 3.6GHz Quad-Core Processor (£70.27 @

Optical Drive: LG GH24NS95 DVD/CD Writer (£11.99 @ Amazon UK)

Total: £300.13

The intergrated video on that apu is 2 times more powerfull than the HD 6450

That's great, I'll have to look at a few cheaper parts (maybe AMD A6?) and I think 4GB RAM would be sufficient :)

4gbs of ram will cost you £35 so for a extra £5 you are geting a bargin especially as ram is going up again.

I'd stick with the A8 allso rember you will be dedicating system ram to the APU video card (upto 2gbs) haveing the 8gbs will be great so you can run a 64bit operating system the speed of them (1866mhz) will allso make the APU's video run faster.

The zotac gtx 650 only uses power from the motherboard. 

Looks a good card, but unfortunately out of his price range. I expect I'll buy him an APU
