How To Buy Substitute Low-ESR Capacitors
These are simple, radial electrolyte capacitors.
It was more difficult to buy special low ESR capacitors than we thought, since we kept an eye on cost. We think it makes sense to exchange capacitors if the process is inexpensive - keep in mind that the replacement process itself can go wrong and you would have to purchase a new motherboard plus processor(s) and RAM.
We needed 26 radial capacitors with a 1000µF capacity, 6.3 V and 105°C temperature resilience for our K7D Master. You can find the technical data on the capacitor's case. The capacitor's diameter is about 8 mm, its height is 16 mm, and the distance between the pins (anode and cathode) is 3.5 mm.
These are the capacitors we ordered.
After a little research we placed our order with a small dealer selling capacitors at scaled prices. We didn't get the desired capacitors with 6.3 V, but decided to go with 10 V models instead. Pin distance and diameter are the same on the replacement capacitors, but the new ones are 20 mm high instead of 16 mm. Depending on the motherboard you're repairing, 4 mm can cause some trouble. Before you order any replacement please find out how much space there is between the capacitors and expansion cards such as your graphics card, among others. We did not encounter any problems with a 4 mm difference in height. We paid 50 cents each for our 30 capacitors, shipping and handling not included.
