| Squilliam said: Benkenobi that PSU is cheap and it only has one 12v rail. I would seriously advocate that people purchase a PSU which meets ATX specifications and uses 2 12V rails to ensure stable power delivery but in any case I would probably add another $10-20 for the power supply if you're going the build your own route instead. |
I don't know if I'd advocate buying a cheap PSU since that's the one component that has the highest potential for bricking a system.
If you do the pre-config route and do a low(er) power GPU upgrade like the 4670, assuming the factory PSU is about 350w, I wouldn't upgrade it unless you were planning on using a better quality unit, in addition to supplying more power.
One 12v rail is all you need if you're only running that one low power video card. It's also all you probably should be using in the 300w range.
Quality PSUs tend to run a bit closer to $100, less if you can find a rebate or sale. IMO, the PSU is one component you really don't want to cheap out on in terms of quality.
