I want to bench AM2+/AM3 but not (bulldozer/piledriver). with ln2 ofc.

 

What's a good PSU? Some light research suggested AX1200, but it's a really old unit, and I don't think I need that kind of wattage for 2d.

 

Thanks

Any high quality PSU with ~600 W and more will be totally fine for that. The power consumtion of CPUs on LN2 is not that high anyway.

 

I used an IKONIK 1000W PSU for years and now changed to a LEPA 1600W for my normal bench-rig. This week I did some benching on a different Setup and they only had a Fractal Design 600W PSU. It was enough to do 3D Benchmarks with Ivy-Bridge on LN2 and a GTX 780Ti on air.

PSU requierements are often way too exaggerated, both by companies and users. That said I would recommend 700W+ single rail with good efficiency (gold or better) and many pci-e contacts. Simply because that's my view of a good benching psu. Now running Cooler Master V1000 and happy with it. You never know when you want to start benching graphics

Yea, i'm a big fan of single 12V rails for benching.

 

Something like a 760i would be great for 2D and if you want to add 3D into the mix, i'd suggest something like a fully-modular 1K+ unit.

I'd say quality is more important that wattage for those things. I've always used singlerail PSUs, so I recommend that as well. Corsair AX series is rather good. I'd also recommend a PC Power & Cooling 610w or 750w silencer if you find the original units for sale benched a ton of older stuff on those units before I got my first AX1200w.

Thanks very much for the advice!
