Have i got enough power for this new build?


Jul 25, 2011
Hi, im building a new computer in a few days time and there are some area's im not sure if i have enough or too much power.
Im going to be using my computer for recording HD gameplay off my xbox and rendering in sony vegas/adobe after effects in 720p/1080p for youtube as my current laptop isn't powerful enough. Also in the future i want to be able to play some PC exclusive games on it but not alot and i wont be taking it too seriously so can anyone help me with making my build better?
Also the main thing i am concerned about is the power supply. How much should i spend on one so it is future proof and will be able to take a £150 once i have saved up?

One last thing that i still cant work out by looking at forums is will i be able to connect my computer to a HD TV with a HDMI cable so that i can play a BLU RAY DVD on my computer but actually watch it on my TV? Also if my TV set up has a surround sound will the sound come out of it even if its being played on my PC?

Thanks for reading :)

The good modular PSU's run between £100 and £150.
I would recommend either Corsair HX750 or HX850, depending on how much power you want to have.

To play games on your system, you do want to get a discrete video card instead of running the stuff with the onboard graphics.
AMD 6870 or 6950, GTX560 or GTX 560 Ti will do that. It pretty much depends on if you want max settings on them or not.
All of the ones mentioned above will do a good job.

To play bluray's you need a player SW in addition to having the drive that can read the disks. PowerDVD 10 or 11 ultra will work.

Depending on your video card the uncompressed sound should be delivered via HDMI to your HDTV setup, ideally to the receiver that handles the surround speakers.
It may also work so that it goes through the HDMI to your TV and then a SPDIF between your TV and the receiver transfers the sound to the receiver and then gets played from the surround system.

Okay that sounds really good, it will be at least a couple of months before i think of getting a GPU tbh. What would i look for in a good PSU... AMP's/voltage/rails?
Also is a £100 needed for a 6870 for example? i was expecting more like £50-£80 or is £100+ manly to make it future proof incase i get two GPU's.
What sort of graphics would i get off of one 6870? would i be able to max out or maybe come in just under to keep it smooth.

Also i wont be playing Blu ray DVD's off a CD so i don't need the Blu ray player. But if i can play sound through the speakers from the PC aswell, that would be amazing!

Thanks for the advice :)


look for wattage, single rail or very high amp multiple rails. 750W is enough to run 2 of most graphics cards except for the very high end.
If you only go for one graphics card a 500w to 550W will do doesn't hurt to have more, but going for quality brands is adviceable.

Antec, Corsair, Seasonic, Silverstone and XFX would be the preferred brands.

You can really get good XFX units for much less that £100.
650W - 850W XFX PSU's are betwen £66 and £76
Corsair TX 650 V2 is good too at £65

GPU: you are looking at £150+ for the GPU's that can run most games at 1680x1050 at high settings.
6870/560 = 1680x1050 with high settings ~£155
560Ti/6950 = 1920x1080 with high settings ~£180-210
