[citation][nom]bonabnz[/nom]Yeah... you're wrong again... of course more value to what i choose, i don't have to buy Radeon 7750 which cost $109 mean while i can buy Corsair or Seasonic 400watt PSU (w/ Bronze certified) just 61$ only. And, the most important, the Chieftec FI-01W case with built-in PSU have NO BRONZE Certified and has 200watt only. If fact, you never right answer to give me some comment![/citation]
By not buying the 7750 you are making a trade-off to get much weaker gaming performance. The value of your build is subjective, not objective. It is you who is wrong because of that. Furthermore, although you can buy a PSU, that'll make it more expensive than Tom's build with less performance. Power efficiency takes a back seat when power consumption is already this low, especially when you're literally paying more money for less performance.
From an objective point of view, your build has a mere fraction of the gaming value that Tom's has. Even better, until I pointed out the PSU mistake, your build had no PSU- so it wouldn't even work. I fail to see how a very expensive paper weight has more value than Tom's entry level gaming system. It's not like it even has much value. It's still very expensive for its performance. However, it runs whereas yours does not. Including both a Radeon 7750 and a PSU will make it far more expensive than Tom's for comparable performance, making it again lose in value.
Tom's case's PSU doesn't need to be 80+ Bronze certified nor more than a 200W model to run for this job. It isn't great, but it gets the job done.
