Power supply upgrade questions

I have a FSP 250 watt (+3.3V 14A, +5V 25A, +12V 8A) PSU, AGP, and a single IDE hard drive. PSU measures 150 x 140 x 85mm (is this the standard ATX PSU size?).

All the PSUs I've looked at have PCIe and S-ATA connectors. Can I use one of these (ie Is the PCIe thingy just an extra that I won't use?), or do I need to find a specialised AGP/IDE PSU?

Confused! Advice needed.......

most existing mobos have a 20 pin socket for the main power supply - the newer ones also have a separate 4 pin socket. The latest have a 24 pin socket. Check what your mobo has and then make sure that what you buy will fit. The atx is pretty standard these days. The higher wattage the better most are nowadays 400 to 500 Watts.

I bought a cheapish PSU to my cost and then invested in an Antec NeoPower 480 and am very pleased with the result (cost about £70 though)!

Thanks for the replies. Embarrassed to say I'd given up on this topic getting any response! Bought and installed new power supply tonight. 400 watt Jeantech, £30. Bloke in shop assured me it was good enough to run any nVidia 6800 ("You could run a street off that!", was his response to my question about said card).

Loads of left over wires/connectors. Just taped them together and left them in the bottom of the case.......

One question. It has two ratings for the 12V rail:-

+12V1 15A, and +12V2 17A

Why two ratings? Was the bloke lying, btw? Is it too weak for high end AGP cards?!

There is a major rail feeding the psu and a minor rail feeding other components.

should read cpu not psu.

Myself, I wouldn't touch a jeantech £30 psu with a bargepole but I hope it serves you ok.

Oh, no! Why, what's wrong with it? Have you seen a bad review of it somewhere?

Seems quiet enough. Is it going to catch fire?!

Please Cybermaxx dont panic,I havn't read or heard anything bad about your psu. Its just that when I buy pc parts I save up and buy the best that I can afford.

hmmm, thinking about it, I just might consider buying one. Are you happy now?. :-) Hope so.
