Hey great news, You should be able to use a r7 250e. its a 55w tdp so it should work. It is the exact performance of a r7 250

I wouldn't recommend running it on a 250W PSU, especially OEM ones. If the system is put under gaming load (even though you mentioned that it will never be under load), then crashing, kernel power BSODs etc. will be expected. The CPU has a 95W max TDP and the R7 250 at a gaming load consumes 150W according to TH's own review.

Those 2 by themselves consume 245W of power. The GPU is supported by its motherboard due to its PCI-E X16 lane, but not recommended with such a PSU.

Like i said. it could work, but the tdp of 65 is a little risky for 250 watts. But hold on im gonna put it thru a watt calculator.

Web browsing won't put a quad-core Phenom at 100% load, would it? They said they won't be putting it under heavy load; the more power hungry component in this case is the GPU.

As SR-71 Blackbird said however, the PSU will be slowly deteriorating.

Yeah your right. But remember, if it says 250w its only able to output a lower amount. Like my rosewill power supply. it says 400w but ouputs only 374 to the graphics card /fans/pcie/ext., 24 to the motherboard, and 12 to the cpu.

I don't understand your wording. I'm guessing you're referring to the 12V rail/s. Yes, you are correct. However, the PSU's absolute maximum is actually higher than 250W.
