Bought cheap e3-1245v2 brand new one of these, put in 16gb, an ssd, a 10K velociraptor, a 1tb seagate sata, and a gtx 1050ti. This little thing has a 280w psu, with nothing but the PC on I'm seeing 36w browsing and 160W with cinebench and heaven running on my cyberpower UPS display. It never occurred to me to wonder how accurate, if at all, the load wattage reported by a UPS is. I know most people, myself included, tend to over-watt psu's but can this little thing really be pulling so little power with the GPU and CPU maxed out? I know they are both probably 75 watts each or so in theory at full tilt, so.. maybe so?

I have a Seasonic x-850 I'd been saving for something and I did order a cheap adaptor plug and install it just since I had it handy (and I wanted the larger exhaust fan it has in play) and it worked fine for a few days but has started flaking out on sleep/wake and flat out turned off and would not come back on, so I stuck the stocker back in and all is well. Either the adaptor cable is crap (could not dupe failure on the bench) or there is something on the motherboard not playing nice with the PSU. I'm happy to leave it be if this rig is really only dancing around 150ish watts, it's just for work and some gaming here and there. Thoughts?

Yes, the Ivy Xeon's are pretty miserly. I got an E3 1280v2 not long ago & even during rendering it's 44-46 watts @ 3.7ghz . My GTX 570 is the powerhog, but still does what I need. I'm using a bit more than your PS could deliver, but with your 1050ti you should be fine.

Thanks Burpo, I guess I'll leave it be and marvel at the efficiency of modern cpu/gpu combo's. Far cry from my old FX/crossfire rig lol......
