Doesn't Topcat ship to your country?

Isn't he supposed to add his country info in his profile?

Re: Amacrox AX650-GLN Free Earth

i have the same psu from FSP, 60GLN series

but i replace the 100uF/25v with NCC KZE 100uF/35v or NCC KY100uF/25v
and the 2200uF with panasonic FC 2200/6.3v

thats the only caps that i can get in my country

Re: Amacrox AX650-GLN Free Earth

I did a partial recap on that psu:

1x100uF 25V Capxon bulging -> 1x100uF 25V Rubycon YXF

1x2200uF 6.3V Capxon (5vsb) -> 1x1500uF 6.3V Nippon Chemicon KZE (removed from a dead mobo)

My friend wanted to spend no money for that psu to be repaired, so I replaced only the bad caps and used stock caps as replacements.

Voltages after recap:
5vsb: 5.12V stable
-12V: -12.37V - -12.40V
3.3V: 3.36V stable
5V: 5.08V stable
12V: 12.42V - 12.44V

pc config: Athlon 64 X2 5600+, 2x1GB DDR2 667MHZ, MSI K9N Diamond, MSI 8600 GTS, 2x320GB Seagate Sata 7200 HDD, 2xOptiarc DVD-RW, 5xcase fans with leds.

The psu fan is blowing a lot of air outside the power supply. Definitely not a silent psu.

Re: Amacrox AX650-GLN Free Earth

Fsp psus ar egetting junkier by the hour. They have undersized heatsinks, crap caps, low capacitance crap caps, and are overpirced. The moral of the story: dont buy them.
Ps: my dead ocz stealthxstream looks pretty much exactly the same inside

Re: Amacrox AX650-GLN Free Earth

No

[goodpsusearch]

Re: Amacrox AX650-GLN Free Earth

3.3V:
2x2200uF 6.3V Capxon
5v:
2x1000uF 16V Capxon
12V:
2X2200uF 16V OST

Am I the only one who finds these filter caps a little undersized for a 650W psu?

Re: Amacrox AX650-GLN Free Earth

Is it nice silicone? Lol jk. Yeah thats what i was thiking. But for tue ridiculous price of some of their products, theu should be better

Ps: i opened my nearly new fsp atx-300pa it has capxon primaries and a mixture of ost and teapo everywhere else. At least there are no fukyuus

[c_hegge]

Re: Amacrox AX650-GLN Free Earth

Yes because less surface area means that the fan has to rev like a jet engine to prevent the silicone overheating.

Re: Amacrox AX650-GLN Free Earth

Is it reall bad to make the heatsinks so small?

[stj]

Re: Amacrox AX650-GLN Free Earth

that last cap is obviously on a small circuit board when you replace it you should replace the heatshrink sleeve - it may be used as a heat shield.

i'v seen fsp put that over caps a few times.

Re: Amacrox AX650-GLN Free Earth

FSP and Sirtec/Highpower are really good at using undersized heatsinks.

[shovenose]

Re: Amacrox AX650-GLN Free Earth

Ok! Someone agreeS that sometimes fsp uses inadequate heatsinks and shit caps! Yay!

[japlytic]

Re: Amacrox AX650-GLN Free Earth

Heatsinks appear to be undersized for this wattage, and CapXon and OST electrolytics are known bad units.

[shovenose]

Re: Amacrox AX650-GLN Free Earth

Edit: i meant fsps use of tiny heatsinks.

[shovenose]

Re: Amacrox AX650-GLN Free Earth

Yeah i always wonderabout faps use of ti yheatsinks but anyway mydead ocz stealthxstream is based of that same design

[c_hegge]

Re: Amacrox AX650-GLN Free Earth

Look at that tiny primary heatsink. LOL

[shovenose]

Re: Amacrox AX650-GLN Free Earth

Fsp is decent (not great) but they use crap caps. Replace all the capxons and blow it out well with an air compressor. Then it will be a good psu.
And yes the caps are casuing the voltage fluctuations

[goodpsusearch]

Re: Amacrox AX650-GLN Free Earth

Btw what is this thing?

The last capacitor in my list is placed in there.

[goodpsusearch]

A very good friend has trouble with his desktop.

When he presses the button the fans spin but it never boots.

I checked the voltages with a multimeter and found they were continuously fluctuating, so I tried another power supply and then his computer booted normally.

The faulty psu is an Amacrox AX650-GLN and the OEM is FSP.

After I opened it I found 2 bulging capacitors. Here is the capacitor list of the power supply and some photos:

Capacitor List

1x470uF 420V Capxon
1x22uF 50V Teapo
1x2.2uF 50V Teapo?
1x100uF 25V Capxon BULGED
1x47uF 25V Teapo
5vsb:
2x2200uF 6.3V Capxon 1 BULGED
-12V:
1x1x1000uF 16V Capxon
3.3V:
2x2200uF 6.3V Capxon
5v:
2x1000uF 16V Capxon
12V:
2X2200uF 16V OST

1X16V Capxon

Is that a good psu? Is it able to do 650Watt without ripple going out of specs?

Do you think the voltage fluctuation is related to the bulging caps?
