New PSU Due to PC Failure


OSNN Senior Addict
Hi all

For the last couple of months my pc has been randomly freezing, restarting or just generall messing up, ive asked people on here b4 n they have said it sounds like a PSU Problem instead of a HD one which i suspected, and as Replacing the PSU is the cheaper option i was wondering if any of you could help me out.

Ive found a 450W PSU for £50

and a 550W Triple Fan PSU for £31.87

A Few Questions Why is the 550W Cheaper?

Is there anything i need to know before replacing PSU as this is the 1st i will have done it

Is My motherboard able to cope with 450W or 550w?

Do i need new cables?

And Due to the basic explaination of my pc freezing, do u think it is the PSU Because b4 Pc Freezes or Fails theres a discintive Click noise with wat sounds like a fan stopping?

Pls Help

Clicking noise is the HD going back to parking its head, and then quickly spinning up and being used again.

This is caused by a bad PSU.

Anyways, your mobo can handle everything fine, it will draw just the power it needs.

Anyways triple fan? Holy **** that would generate a ton of noise. Also, make sure they are not rated at 550 watt, and then can only output a continued 400 watt with a peak of 550 watt (Yes, some manufacturers do that, to be cheap). And get a nice silent one as well, unless you want a PC that sounds like a jet engine.

/me goes to find his ear muffs

Make sure the new PSU is P4 compatible (has a small 4 pin connector required for all new P4 systems and some newer AMD MB). It's the way everything is going.

Make sure the +5V rating is 28 amps or higher and the 12V rating is 15 amps or higher.
Make sure the combine 3.3, 5, 12 volt outputs do not have a power limit much lower than the overall supply. Cheapies may be rated 450W but the 3.3/5/12 combination can not exceed say 280W.

Look for a comparably priced Antec or Enermax supply rated 380-400W before you buy an off-brand unit. Quality is higher and they do nice things like replace your PC if the supply blows and takes other parts with it.

PS There is no guarantee a new PS will fix the problem. It can literally be anything (sounds card, video, RAM, CPU, MB, PS, HD, incoming power from the wall). Swapping parts one item at a time is the only way to isolate it.
