I'm going to replace all caps.
Here is list of capacitors.

Antec NEO HE550 Google Spreadsheet

Most are OST, but there is few Jen Pans (JP) and one Teapo.

I found datasheets for OST RLX and RLS and Teapo, but for some capacitors I could not find values.
For JP I could not find datasheet.

Would Panasonic FM or FR be good replacement for OST caps? Also 68uF 25V I could not find any replacement. Can I have different Voltage / Capacity instead?

How about JP and Teapo, FM or FR good choice?

RLS Datasheet
RLX Datasheet
Teapo datasheet

Fm and Fr will work fine, just be sure that you replace evey cap in the psu including the smaller ones as they are all probably internally failing and could cause the psu to fail shortly after.

Re: Antec NEO HE550 Caps replacement

Ok thanks. Which one is preferred FM or FR?

And how about that large one, 400v 390uF. Does that need to be replaced.

Wha brand is it, and fm and fr are both great caps ?

Just replaced all Antec EA-380 Ost caps with Panasonic FM, FR and FC.

Oh man, this is grandpa

Looks like some kind of modular version of the Seasonic Super Tornado.

According to Hardware Secrets, there is NCC SMQ input cap. I would leave it there. But for 550W unit, I would myself use 3300uF caps. I can provide you with NCC KYA 3300/6,3 and Samxon RS 3300/16, both D10.

Talking of your samxon rs I will be buying some with in the next 2 weeks

Their electrical specs are actually quite similar. FR are often physically a bit smaller for the same capacitance and voltage, so they are sometimes all that fits, but if an FM fits, it will be fine

If you need to, you could replace the 68uF 25V cap with a 68uF 50V if its any easier. Panny FC and Nichicon PW are also good options for those small caps.

by the way, where do you plan to buy your caps from? I'm pretty sure element14 and RS components will ship to Finland from the UK.

**Behemot** · 03-05-2015, 03:21 AM

Re: Antec NEO HE550 Caps replacement

I ship worldwide using airmail, which is often far cheaper than courier services of these big reseller corporations…

Re: Antec NEO HE550 Caps replacement

That is true, but I don't think you have everything he needs, though. There are a number of 2200uF 6.3V caps in there, which I haven't seen on your website. I really wouldn't recommend changing the capacitance and electrical properties of the caps too much in these Seasonic Super Silencer platform based PSUs, as they have much more picky feedback loops than some.

**Behemot** · 03-05-2015, 04:06 AM

Re: Antec NEO HE550 Caps replacement

Yes because I only use 3300uF caps. Why using 2200 when I have 3300 in the same package, maybe 5mm taller? Makes no reason to source extra 1000 pieces I will really "need" in 1 case of 20. And than I can still use KZN 1500 D8 with probably the same ESR as KYA/KYB in 2200 D10.

E8200, yes thank you, that was very good for initial research.

FR having bit longer life time and it is cheaper so I'll get those.
At least Elfa has good stock, but I'll compare other shops as well.

For OST RLS 68uF 25V, would Panasonic FM 35V be OK replacement?

Code:

68uF 25V		Volts	Cap	Dia	Length	Ripple 	Impedance	Part
OST RLS		25	68	5	11	250	0.13		
Panasonic FM	35	68	6.3	11.2	455	0.13		EEUFM1V680

For OST RLS 220uF 16V I could not find Panasonic or Nichicon. Any of these will be suitable?

Code:

220uF 16V	Volts	Cap	Dia	Length	Ripple 	Impedance	Endurance	Part	
OST RLS		16	220	6.3	11	405	0.13		2000		
Rubycon		16	220	6.3	11	540	0.094				6ZLH220MT16.3X11	
Panasonic FM	25	220	8	11.5	950	0.056		3000		EEUFM1E221	
NIC Components	16	220	8	11.5	560	0.16				NRSZ221M16V8X11.5	
Jamicon		16	220	8	14	400	0.18				WGR221M1CF14VU

You have some webshop?

Would 3300uF handle higher loads then better? The bloated one was 6.3v 2200uF. So maybe I'll consider to replace with 3300uF. About impedance should that be about the same? Better to be lower or higher? How about ripple?

**Behemot** · 03-05-2015, 05:11 AM

Re: Antec NEO HE550 Caps replacement

I have a stock overview in english.

KYA 3300/6,3 has impedance of 42 miliohm, ripple 1650 mA. Could be somewhat lower (ripple current higher), I will order KYB next time, but those OST RLX are too low for my taste, those are basically ultra-low ESR caps (motherboard grade) with only 2000 hours life and who knows if they ever even had such low ESR as the datasheet says. Not sure why Seasonic used them in power supply. Maybe there was nothing better at that time…anyway, I use only these caps all the time and everything works fine so far.

If that RLX datasheet is to be believed, than I can offer KZN 3300/16 D10x40 mm with 18 mΩ and 3,6 A, they will be fine there (other supplies may oscillate with such low ESR, but if this one really was designed for MB grade caps, than it will surely be OK). Lifetime of 10000 hours@105 °C.

Ok, I'm checking. For these I could not find replacement:
OST RLX 3300uF 10V
OST RLS 68uF 25V
Jen Pan ce-tur 1000uF 6.3V

**Behemot** · 03-05-2015, 06:23 AM

Re: Antec NEO HE550 Caps replacement

You don't need 10V caps, for lower voltages use 6,3 V and for +-12 V use 16V caps. Instead of that CEC, use KZN 1500/6,3.

Where exactly is that 68uF cap? I usually replace that with either 47, or 100uF cap, depending on what it does. It is very uncommon value.

EDIT: From Pentium4's thread there's a photo, which cap that is? If the bigger one, it does not matter, it is there to filter Vcc voltage for the stand-by rail PWM controller.

That is OST RLS 68uF 25V

**Behemot** · 03-05-2015, 06:39 AM

Re: Antec NEO HE550 Caps replacement

Yeah than you can use KZM 47/35 or LXZ 100/35, both will be fine.

That
OST RLX 3300uF 10V
is found in same picture in lower right corner. What should use for that?

Please check my doc if these would be ok replacement:
Antec NEO HE550 Google Spreadsheet

Yellow ones are the original, green ones replacement.
