I can be very lazy at times. For example, I never bothered to even attempt to add up the wattage of all the stuff in my system.
Originally it had 3 hdd's, 1 GPU, the five fans that came stock with the case (Silverstone TJ07) and a DVD writer.
I don't remember what PSU I used but this system has blown about three of them so far.
My last PSU (Corsair 1000 W) got pulled out and was being readied for an RMD because my system kept randomly shutting down. By that I don't me BSD, but it just shut off. Turns out that the heat sink fan on the CPU came unplugged so the power supply is fine and is now a spare.
In the mean time I bought a 1300 W PSU because I had 6 hdd's, 1 SSD and dual GPU's in SLI.
So now I have an inline watt meter and typically the PC is drawing about 225 watts. That's my PC, the monitor and my cordless phone base.
The MOST watts I could get the system to draw was just about 325 when doing 3D Mark benchmarks while simultaneously copying a large file from each drive to another drive. So every drive was being read and written to. The only thing that wasn't active was my blu-ray burner.
Any game I play (Skyrim, Fallout 4, etc.) only takes the wattage up to about 295 with it occasionally bumping to just over 300.
So it looks to me like I could have gotten by with 450 (probably pushing it) to 600.
When I was building the system I was in another forum (can't recall the name) and the recommendations were minimum 600 and preferably 750 watts.
So why am I drawing so much less than I thought?
