tell me what pc psu I need

[colin1]

I've got an old PC which is from 2003. My PSU is on the way out. I guess that PCs have different power supplies. So if I get one off ebay, what keywords do i need to know ?atx maybe ?

what power supply have you got in there at the moment? What connections do you need? I tended to go for a slightly higher PSU than I needed. I always go for at least 750w (think they are from about £35 upwards)

Yes you need an atx one. The main board connector is the same, but modern PSU's will come with some extra connectors you don't need. Check if it comes with the old style chunky hard drive power connectors and not the smaller SATA ones.
Most come with both, or converters.

My last psu was a 750w CiT, OK so it only lasted 4 years with the PC being switched off for a total of 4-5 nights in the whole 4 years, the rest of the time it was worked hard.... and that cost me about £30-40. But thanks for the advice there carvell, I'll remember in future to buy a lower powered branded one that probably wouldn't even get close to starting my system....

PSU Wattage claims are pretty much up there with vast pixel counts on cheap cameras, that big shiny number doesn't actually mean it's any good. A smaller quality unit from a respected manufacturer will not only last longer, but will usually come with a better warranty just in case it doesn't.

It's also worth noting that very few PCs from 2003 will need anything close to 750w. It's likely going to be a northwood P4 or late Athlon for a machine of that vintage, a good 400w will cover that in it's sleep.

i am running a corsair cx 400w with an ati 3870 and a stock clock phenom 9950. i would think if its a pre-built machine it will only have a 350w PSU in anyway.

that PSU was £33 2 years ago from OCuk. i havent been in the market for a PSU in a while so cant tell you how much something like that would cost.

on a side note, i have seen cheap PSUs take out motherboards as well, granted its very rare for that to happen but bare that in mind before you spend next to nothing on a PSU

Job done. 500w is way more than you'll ever need. If you're running a PC from 2003 then even if you do upgrade chances are you'll buy something low spec in which case you can reuse that power supply in your new system. Or you'll probably just buy some pre-made system in which case it doesn't matter

Yes clearly his 9 year old PC needs one of these or he will be laughed at where ever he goes.

i got me one of these in my mian rig

you have to run at least 2 of these in a 9 year old PC seeing as they they need power per flops of processing power, so putting a big PSU in it you can make even more powerful

It was an eBay thing as far as I can tell, and yes, totally agreed with the whole shooting their faces off thing. I had to grit my teeth many a time when people commented on that at work
