Hello,
I would like to use the following PSU (Coolermaster rs-450-acly)
It has 450watts in total at 80% efficiency and no PCI-E connector (would need to use 2 adapters). On 12v combined 22ampere/264 Watts and Peak 34 ampere/408 Watts. I suppose the "Peak" is the absolute limit before it shuts/burn down and for lifetime/stability purposes I also shouldn't run constantly on the "Continuity" Limits so I guess it is OK to count with 250w on 12v as Target?
It is supposed to run the following Components:
CPU: I5-3350 -> 70W
GPU: 7870xt -> 210w (undervolted about 180w)
RAM: 16GB Crucial Ballistix Tactical LP CL8-8-8-24, low profile (DDR3L-1600)
HDD: Toshiba DT01ACA Series 2000GB, SATA 6Gb/s -> 6W
SSD: Samsung SSD 840 Series 120GB, 2.5", SATA 6Gb/s
Case: Micro ATX Cube Aerocool m40 http://
DVD: 1-2 devices
So I got 250W(408W Peak) on 12v, The CPU,GPU and HDD will suck 300W in the worst case I guess. Obviously that's too much, if I undervolt the 7870xt as intended It will save me about 30 watts, so I'm at 270W, still to much, but not so far from the 264 promised watts. These watts I probably could gain by undervolting the CPU aswell. In the end, I believe it would stay usually below the 250W Target still very tight stuff.
I know, usually it would be recommended to use a stronger PSU, but actually I really want to use that one, possibly even go for a 660ti or standard 7800 if necessary but the above combination is my favourite by far.
Leaving me to the following Questions:

Leaving me to the following Questions:
■Do you believe, this PSU would be capable to run with the above components in the Aerocool m40 cube for several years without emergency shutdowns etc.?
■As the PSU has no PCI-E connector, will two 2x4pin to 6pin adapters work without further problems? (I've seen 1x4pin to 6pin and 2x4pin to 6pin - whats the difference, recomendation for one of them?)
■The operational Temperature is declared as 40°C which seems quite low too me, although in this test http:// it runs fine on nearly 50°C... Do you believe it will cause any Problem regarding the small aerocool cube case?
