[SOLVED] Help with replacing capacitor on OEM PSU

I have a Delta DPS-300AB-73 B PSU from a HP Pavilion gaming PC (2017) with a 1050ti.

Awhile ago I had a capacitor fail in a Corsair CX600 (who would have guessed), so I robbed a capacitor from this Delta PSU, which fixed the problem. It was a 10v 2200uF capacitor, from what I think was this spot on the PCB:

Here is the only photo I have of both capacitors:

The top cap was the bulging one in the CX, the bottom one was the cap from the Delta.

Unfortunately, I do not know for sure the temp rating nor brand of the original cap in the Delta. All of this was documented on the jonnyguru forum, but sadly that's gone. I also no longer own the CX, so I cant open it and find out.

I still have the failed cap that it replaced, which is 105c, so I would guess the cap from the Delta was 105c. I would also assume since it was blue, it was Ltech branded like the other blue caps in the Delta. I am not 100% sure of either of these things.

I am looking to use this PSU to power a pc i'm making of spare parts. Nothing fancy, an i3 550 and probably no dgpu, but maybe a GT1030 or something.

Could someone point me in the direction of where to get a replacement capacitor, and what type of capacitor I need?

If the uF and V ratings are the same it should be ok. Be carefuly where you buy caps from (read the sellers reviews). Try to get japanese or taiwanese caps.

I think it's more important to get your capacitors from a reputable vendor that has proper storage practices and good stock rotation. I don't care if it's a Japanese capacitor if it's been sitting in a garage in Florida for five years.

See if a friend or colleague owns an ESR meter. I don't expect you to buy one as they cost more than a new PSU, but it can put your mind at ease that the caps you buy are the correct uF and ESR. Improperly stored, old capacitors will generally have low capacitance (uF) and high ESR.

Solution
3x Panasonic FS 2200uF 10v Low-ESR Radial Capacitors 10000HR @105°C 10 X 20mm | eBay
These are what I ended up purchasing. They should arrive tomorrow.

I didn't consider storing conditions, but that info will come in handy the next time I need to replace the caps in a PSU. I will just have to hope these caps weren't stored improperly.

I figured I would go with a good brand like Panasonic since generally worse branded caps cost similar amounts.

I don't have an ESR tester and don't know of any way to get access to one to be honest. Even my multimeter is on the fritz and I need a new one :ROFLMAO:

Not sure if he's going to buy an ESR, he has been harvesting CAPs out of donors....

Just sayin...
