MoBo compatibility with power supply

Tornik · Feb 16, 2017

Hi, I'm planning to buy the GIGABYTE G1 Gaming GA-Z170N MoBo and would like to check if it is compatible with these two power supplies:

Thermaltake 730W - SMART FAN 120mm SP-730P
Thermaltake SMART SE 730W (SPS-730M)

If other specs are important for this question: i5-7600K | GTX 1070 | G.Skill Ripjaws V Series DDR4-2666 16GB (2x8GB) | Samsung 850 EVO 500GB SSD | Cooler Master Hyper 212 Evo | Phanteks 140mm Case Fan

Thanks in advance.

In terms of compatibility, yes. But in terms of price/performance/reliability, I would look into other brands and lower wattage.

The two power supplies you are looking into have been reviewed and categorized as Tier-4 in this oftenly-referenced PSU Tier List.

Tier Four
Built down to a low price. Not exactly the most stable units ever created. Very basic safety circuitry or even thin gauge wiring used. Not for gaming rigs or overclocking systems of any kind. Avoid unless your budget dictates your choice.

I would highly recommend looking a PSU listed in the Tier-1 and Tier-2 categories for their quality and safety. Note that not all upper tier power supplies are expensive.

With regards to the actual wattage you need, a good ballpark reference would be your GPU (i.e., a GTX 1070). Have a quick look at another oftenly-referenced site by RealHardTechX listing the Recommended PSU Requirements. A rig built around a single GTX 1070 GPU is recommended to only have a PSU wattage of 500W (for the whole system). If you plan to SLI the GTX 1070s in the future, the wattage can be 700W (close to the 730W you are initially looking at).

Note that these recommended PSU wattage already takes into account the other components of your rig.

Personally, I would recommend the following affordable but better performing PSUs:
- Seasonic G Series
- Seasonic X Series
- Corsair RMi or RMx Series (not the RM series, which is of lower quality)
- Corsair HX or HXi Series
- EVGA SuperNova G2 or GS Series
- Fractal Design Edison M Series
- XFX TS Gold Series
- XFX XTR Series

Many thanks for the detailed reply and explanation.

As I will need to go through recommended PS models, what are the specs I should look at to be sure about their compatibility with the MoBo I mentioned?

Here's a very good reference you may want to browse if you are comparing PSU specifications/models: http://www.gamersnexus.net/guides/866-psu-dictionary-understand-psu-specs

Generally, in the list of PSU models I have recommended above, there will be no issues in terms of compatibility with your motherboard. You may want to take a closer look, if you are that detailed, on the included cables the PSU have (including cable lengths and number of connectors) against the case and components you would put in your rig. I would pay close attention to the number of PCIe connectors your chosen PSU will have because your GPU will depend on it. The number of SATA connectors and Molex connectors is also important if you have a lot of HDD, SSD, ODD, fan controllers, and other miscellaneous components that require such connections to the PSU.

Another spec to consider is the physical size of the PSU (some are smaller and some are longer, but the difference is only a few cm). This is only important if you have a small/tight case with less room to manuever your cables (like obstructing a bottom fan slot or hard drive cage).

I would also recommend not paying too much attention with the "80PLUS Rating" system, as they are highly subjective. You can get by with a "lower" 80PLUS Rating such as 80+ Bronze or 80+ Gold compared with the "higher" and more/ridiculously expensive 80+ Platinum and 80+ Titanium models for almost the same efficiency based on average use. I highly suggest looking at the 80+ Gold models as the max. for best price/performance.

Hope these infos help.

Absolutely. Thanks again, your help is greatly appreciated.
