Cables and Adapters -- Dilemmas

Cables and Adapters --> Dilemmas
I'm a bit worried about the use of adapters of high-current supply. Those seem to be high-current supply:
* 24-pin ATX main power cable
* 4-pin CPU cable
* 8-pin CPU cable
* 6-pin PCI Express Cable
* 8-pin PCI Express Cable

My concerns are bold. If my power supply don't have those cables, what can I do? Can I still use adapters as workaround? What're the problems/disadvantages?

6/8-pin PCI Express Cable has three +12V wires. If I use 4 pin peripheral connector adapters, we use 2 peripheral to convert into PCI Express connector. But I only get two +12V wires in this way.

8-pin CPU cable. It has four +12V wires. If I use 4 pin peripheral connector adapters, we use 2 peripheral to convert. But again I only get two +12V wires in this way.

ATX 20+4 pin main power cable. I wonder if it's ok to use 20-pin power cable + 4 pin ATX +12 volt power cable (for CPU) to match the 24-pin requirement.

Thanks.

If your PSU does not have those cables, it may not even have enough power to supply your CPU/GPU.

More information: i.e. PSU make/model, CPU and GPU you are trying to power, etc. would be helpful.

Personnaly, i would not even consider touching any of those wires to make them fit your system (modding adaptors).

Buy the right one for the right pc requirements.

Yes. And I'm not going to do it. Better safe than sorry. Less headache.
But it's still nice to know the answers of the above questions. I'm curious to know. I have been asked a similar question some time ago. Nice to know so I can answer it next time someone ask me again.

This is just a general question. Well, but it's interesting to know if my old PSU can fire up my new system.

Old PSU is a decent PSU. 500W (able to continuously supply 420-430W if memory serves), serviced me for 4-5 years.

This is my coming build (not purchased yet. Feel free to comment on my build):
Mobo: Foxconn P35A-S, Intel P35 chipset, two PCI-Express x 16
CPU: E2180 O/C to 3.0Ghz
RAM: DDR2 800 2GB*2 or 2GB+1GB or 1GB*3
Graphic card:
A) HD 2600 Pro (will O/C), Dual DVI outputs
B) HD 2400 Pro, Dual DVI outputs [not for Crossfire]
Monitor: 20-22", 1680x1050, * 4
HDD * 1
DVDRW * 1

Purpose of the built: Mainly for working, receiving 10+ streaming data, some video/audio editing and recording.
Occasionally, watch video (maybe HD videos too in future). Light gamer who doesn't care about eye-candy.

Looking at Froogle, it seems you can get a HD 3650 for about the same price as the HD 2600.

The motherboard is a decent choice, I would think about at least an E7200 processor.

A high quality PSU is always good investment.

What brand of graphic cards would you suggest?

A high quality PSU is always good investment.

Yes I will definitely buy a decent quality PSU. I won't go for cheap brands.
But I'm not going to buy a PSU with too much watt. It seems it's a waste of money.

With GPUs, you really only have two choices; ATI or nVidia.

I suppose that depends on whether or not you intend to upgrade to a high-end rig in the future.

With GPUs, you really only have two choices; ATI or nVidia.

I mean the brand of the GPU vendors, not the chipset producers.

There are many brands. I know they're all using boards referenced by ATI and nVidia.
I just wonder if some bad brands will cut costs and give us water-down HD3xxx for example.

Assume the same type and size of memory and the same fan, what brands are safe to pick? What should be avoided?

Thanks.
