Hello,

I'm in the works of a new build and I was looking into re-using my current case and, hopefully, the current PSU.

What do you guys think? The current PSU is a 6 year old Corsair TX 650W.

At the moment, these are the parts I'm looking to put together:

CASE: Antec P182B

MOBO: ASRock Z77 PRO3 ATX

PSU: Corsair TW 650W

CPU: Intel Xeon E3-1240V2

GPU: ASUS GeForce GTX 660 2048MB DirectCUII OC

RAM: Kingston 8GB (2x4GB) CL9 1600Mhz HyperX Genesis

+ 128GB SSD och 2TB HDD

My PSU has been running on average 8 hours per day since I bought it.

Would it be unwise to re-use the PSU in the upcoming build? Could it cause harm?

In my experience, dust buildup is the greatest risk factor for catastrophic PSU failure. Make sure the unit is nice and clean.

From what I've read about systematic failure, after burn-in failure rates are roughly constant for most hardware. The PSU fan and non-SS capacitors might be exceptions, though. Neither of those would fry your components upon failure AFAIK.

I'm sure others will have more to say.

Short answer: If it's an economic decision, sure.

Longer answer: Given a benign environment, it's probably good for another 6 years. +1 on the non-solid state caps being the component(s) that will go first. Your proposed system won't see more than ~200-220W while gaming and 260W under stress load. So, the fan won't ramp. If the idle fan annoys you, it might be a good time to put a lower rpm model in there. The only downside is the lower efficiency vs some current models at idle and your load.
