Need Help Picking Psu

I am doing a DIY router using pfSense, and need to choose a PSU. These two seem to be the only ones that will fit my case, and have mostly good buyer reviews:

Seasonic SS-300TFX
Seasonic SS-300TGW

Could use some help picking one. My case is Apex DM-317-A, for any curious.

 

I'd go with Seasonic SS-300TGW.

 

Someone on another forum said both Seasonic PSUs are too wide to fit the case. Can you doublecheck that?

 

Current PSU dimensions: 5.75" x 3.25" x 2.5"

Seasonic PSU dimensions: 6.9" x 3.3" x 2.5"

So it is possible Seasonic is too big.

Many "slim" type cases accept ATX PSU so getting new case may give much better PSU options.

 

I agree. Time to ditch this case. Second choice is HEC Compucase 7K09BBA30FNRX. Haven't been able to track down size of its included PSU, so not sure if either will fit, but hoping for either Seasonic SS-300TFX or SS-300TGW...what do you think? My third choice for case is Apex MJ-16, but not liking its big size at all, so I would see it as last resort.

 

For HEC, PSU is HEC-300W TFX

85x175x65mm (3.3x6.9x2.5)

Same size as Seasonic. So Seasonic should fit in that case.

 

Excellent! HEC may not look as good as the other case, but it will do. Do you have any preference between the two Seasonic models? I could flip a coin, but would like to hear your thoughts. Once I pick the power supply my build will be complete (on paper). Could I impose on you to look it over, and check for incompatibilities or potential problems?

 

My choice would be SS-300TGW.

If you post your system here, I'll check it out.

 

CASE: HEC Compucase 7K09BBA30FNRX
CASE FANS: Noctua NF-R8-1800
CPU: Intel core i3-4160
CPU COOLER: Noctua NH-L9x65
MOTHERBOARD: Gigabyte GA-B85M-DS3H-A
RAM: Corsair Vengeance CML8GX3M2A1600C9
SSD: Either Intel 530 or 535 series; 120GB (whichever I can find at bargain price)
SSD BRACKET: Sabrent BK-HDDF
NIC: Intel EXPI9402PT
NIC LOW-PROFILE BRACKET: Intel E1G42ET
DVD-ROM: Asus DVD-E818AAT/BLK/B/GE
PSU: Seasonic SS-300TFX Bronze or Seasonic SS-300TGW*
MISC: IOgear 2-port KVM #GCS72U

* I am hoping I can get the SS-300TFX to fit, but if you tell me it will not work, then SS-300TGW is the second choice.

 

i3-4160 is old LGA1150 socket so I either recommend waiting for Ryzen 3 or getting Intel LGA1151.

 

That would not fit the motherboard, so far as I know. So is everything on my parts-list compatible?

 

You'll need different motherboard yes. I cannot recommend LGA1150 as it's so old already and motherboard availability will be problem in the future.

Other than that system looks basically OK. Not sure if CPU cooler is small enough to fit case though.
