PSU recommendation

[Namoshek]

Hey guys,

I'm planning to buy me a new rig and I'm not quite sure how much power I really need. I think one of the following four PSUs should be fine, but I don't want to buy one with 100+ watts that I don't need.

Possible PSUs:
- be quiet! Straight Power E9-CM 480W
- be quiet! Straight Power E9-CM 580W
- Corsair CS Series Modular CS550M 550W
- Corsair RM Series RM550 550W

My rig will look like this:
- ASRock Fatal1ty H97 Performance
- Intel Xeon E3-1231v3
- Crucial Ballistix Sports 2x4GB 1600
- Thermalright HR-02 Macho Rev. A
- TP-Link TL-WN881ND, PCIe x1 (WLan card)
- Fractal Design Define R4 (two 140mm fans)
- Samsung 840 Evo 250GB
- 2,5" 1TB HDD (not sure what brand, don't have it with me)
- maybe also a 3,5" HDD (brand won't matter at all)
- Samsung SH-224DB (DVD burner)

For sure I will be using some USB units, but not that much (mouse, keyboard, maybe sometimes external harddrives and USB sticks, ...).

As graphics card I have two in mind:
- Gigabyte GTX 780 GHz Edition
- Inno3D iChill GeForce GTX 780 HerculeZ X3 Ultra
I would like to go with the Gigabyte, but I read that the power consumption is awful, so I decided to have the iChill as second option. Is there a big difference between them in power consumption? And what PSU should I take (for each of them)?

Best regards,
Namoshek

The RM550 would be fine although you're wasting money with that CPU/motherboard combo.

 

[Namoshek]

Why would that combo be wasting money?

 

[Wraith]

£79 for the Fatal1y H97 Perf
£202 for the Intel Xeon E3-1231v3

You could go 4690K for £15 less and slightly greater performance.

Depends mate, for gaming the i5 would be a better option but for productivity, the Xeon's Hyperthreading will come in nicely. He doesn't seem to want to overclock anyway, considering he's going to be on the H97 platform.

On topic:
450 Watts would be enough for your system, but I personally wouldn't comfortably run that hardware configuration on a 450W PSU cause you'll almost be maxing it out.

The You'd get away with the RM550, but personally I'd get the marginally more expensive RM650, just to have some headroom and enjoy that 0RPM fan feature to keep things nice and quiet and take some stress off the unit.

Well, I have no interest in overclocking the CPU (but maybe the GPU ... after some time), but I want to have a CPU with hyper threading because I'm programming once a while and my programs will make use of this feature. So the Xeon will be a good choice because I do not need an iGPU.

The rig will be running in an environment with room temps of 18-22°C, so it should not reach the highest temps at all. If you say 450W are fine, does that fit for the Gigabyte 780 or for the iChill? Maybe the 480W of beQuiet would be fine also...

 

[Wraith]

True enough, Namoshek what are you going to be using your rig for?

EDIT: The Reference GTX 780 will consume 250W and nVidia recommend 600W Minimum, even though this is an exaggerated number as they always do, a 550w would be my minimum but as Feronix said I'd go that bit further and opt for a 650W to be sure.

Fair enough.

No mate, I said that the system could run on a 450 Watt unit, but it will nearly max out the capacity when you use your rig at full load. Just get the RM550 minimum imo.

Besides developing mainly for gaming (shooter and MMORPGs from time to time). Maybe, but only maybe, I'll be doing some video editing... but that depends on how much time I'll have. But I prefer paying 20 bucks more than regret afterwards choosing the wrong CPU.

Edit:
Okay, that is an answer I can work with.
