i have a shipment of capacitors arriving friday. i'm wanting to try an experiment where i fill all the cap spots(instead of just the 3 spots) in front of the processors with 3300uf caps to see if the extra power being available to the gpu/cpu help the xbox's performance. my question is, is there any chance that this will damage the xbox? also, has anyone ever tried this before?

it should work, but dont expect more speed. -
Re: Wanting To Try Something With Extra Capacitors for my original xbox
That depends on the characteristics of the power supply. Adding caps will make the circuit look like a lower impedance as power is applied. It's likely that the power supply will tolerate the increased load -- but, the suppl(ies) may come up slower than they should. Predicting the consequences of that are likely beyond a casual observer's capability.

Re: Wanting To Try Something With Extra Capacitors for my original xbox
it's a vrm outputComment

Re: Wanting To Try Something With Extra Capacitors for my original xbox
the vrm is a low voltage high current psu for the processor core - those 3/5caps smooth it.Comment

Changing Capacitors will not make your xbox more powerful, give it up already you have been told serveral times in many threads.Comment

Re: Wanting To Try Something With Extra Capacitors for my original xbox
Didn't you post this on reddit as well? It's pointless. More capacitors != faster system.
What capacitors did you buy?
Also, those capacitors aren't "fun" to replace without a de-solder pump. You will be happy when you have finished with the first 3.
BTW, I used 3900uf caps (x3) and no visual difference whatsoever at nearly 12000uf total.Last edited by jayjr1105; 10-08-2020, 12:50 PM.--------------------------------------------------------------

Re: Wanting To Try Something With Extra Capacitors for my original xbox
this is not about changing them, this is about wanting to add more so that it will get more power to the chips. i'd have 5 caps instead of just 3 to deliver power to the chips. that's be like having 5 wires delivering power instead of 3.Comment

Re: Wanting To Try Something With Extra Capacitors for my original xbox
Solder sucker and solder vacuum are not the same thing. $200 price difference there. You are not making sense. Just change caps if they are bad and that's it. Populating two extra caps for the heck of it is a waste of time and 2 capacitors.--------------------------------------------------------------

Re: Wanting To Try Something With Extra Capacitors for my original xbox
Increasing the capacitance will not improve anything. OTOH, you are messing with a carefully designed network that probably has capacitors of multiple types, values, impedance characteristics, and locations. You could probably get away with some amount of changes, but you will get no benefit and will risk screwing up the VRM's loop stability and/or the network's transient load response.Last edited by PeteS in CA; 10-09-2020, 03:25 PM.PeteS in CA
Power Supplies should be boring: No loud noises, no bright flashes, and no bad smells.

As the title says, Xbox 360 Polymer Capacitors, replacing all on a Kronos 1 revision board.
I went over a thread here (Xbox 360 with blown caps) and gather some extremely useful knowledge!
If I have things right, I can replace them TO
x9 : 1500uF 16V 10x20mm
TO: 470uF Nichicon FPCAP R7
x2 : 820uF 6.3V 8x12mm
TO: 2.5V 820uF Nichicon FPCAP R5
On this revision, there are other 820uF polymer capacitors for GPU/CPU - I'll be replacing those anyway with the above FPCAP R5
What's a good replacement for the smaller... -
Hello!
I'm looking at an original Xbox PSU: Foxlink ftps-0002 rev. B. The 12 V output is too low, and the 5 V output is too (?) high. Unfortunately I don't have an oscilloscope but only a DMM for diagnosis.
Measured voltages with no load:
After rectifier diodes
12V: 6.17 V
5V: 5.67 V
Secondary transformer pins AC measurement (really don't know if this says anything)
12V: 2-2.5 V
5V: 1.04 V
I also have another (working) Xbox psu from Delta. The same measures there, in order, being: 10.79,... -
Hi there, I have an Xbox One original in which I have all the 1.8v, 3.3v and 5.0v standby power rails present, however my 12v rail is not turning on and the enable signal PSU_V12P0_EN from the SMC to turn the power supply on is missing. There is high resistance on this line so it's not shorted directly to ground which leaves me with not many options.
Was looking at a schematic and see the enable is created by the SMC. I have 3.3v on SMC_RST_N_IN but I'm a little stuck on where to look next. Is it likely that the SMC has gone bad or am I missing something else (it's my first time with... -
i have a 1.1v and i am having issues with faint wavy lines on the screen that i am trying to make perfect so it will be my main xbox.. also have some 1.0v's that are doing it but to a lesser degree. i really don't want to do a full board recap, especially don't want to have to replace those smds, so i want to find which specific caps that filter the video signal. i have already replaced several caps and messed up one of them that caused a dead short(has been repaired). so i really don't want to just do all the caps. plus, those 1.1v boards have a lot of them. i'd really like to just focus on the... -
Hey there friends!
I have an original Xbox power supply, model FTPS-0002, that isn't showing any signs of life. I have never really done power supply repairs before but I'm eager to learn so I am hoping someone can help me diagnose this.
The issue is that I get no 3.3VSR standby voltage which in turn leads to no 5v or 12v. A couple things I have noticed in my initial inspection.
Resistor 25 and 29 are both reading OL, Capacitor 17 and 20 seem to be leaking as seen in the photos.
So far I have confirmed that 240v, main fuse and the 400v cap is...
