Hi all I’m after a bit of advise My old Jeantech 500W PSU went Bang the other night so I’m looking for a replacement.

Now PSU’s seem to have moved on a lot since I bought this one So I would like to know the following, will a new ATX12V v2.2 24pin PSU work with an old ATX v1 motherboard?

My motherboard is an ABIT IC7-G 478 socket with a Pentium 4 3.2 CPU which is ATX12 V1 board I believe and I’m thinking of purchasing a 520W Corsair HX Series Modular PSU.
I know that the 24pin can be split to 20pin and you also get the standard 4pin 12vATX connector but what has made me unsure is that the Corsair states “Supports the latest ATX12V v2.2 and EPS12V 2.91 standards and is backwards compatible with ATX12V 2.01 systems”
Please can someone advise if this PSU will work ok with my motherboard and if they would recommend this particular PSU or another?

Thank you in advance for your advice.

Longshot.
 
Thanks for the welcome and reply Admiral Huddy.

I thought it would be fine looking at the section you listed in the manual, but as i said in my post the statement of “Supports the latest ATX12V v2.2 and EPS12V 2.91 standards and is backwards compatible with ATX12V 2.01 systems” Has made me somewhat wary.
 
I would say it's backwards compatible. It might be worth contacting Corsair Customer Support and ask them directly if you are worried. Personally, I wouldn't invest in such a PSU for a older motherbaord.. there are plenty of cheaper "generic" PSUs that will do the job at a fraction of the cost. I'm using a generic 300W PSU i picked up for £20 for one of my workshop rigs.. This is running a nForce3, AMD64 3200+, 2Gb ram, Geforce 6800GT no probs.
 
Thanks again, I normally would agree with you and just get an older cheaper model but the Jeantech one i used to have went so spectacularly bang after only a couple of years use that i would rather shell out for something a little more robust.
 
The corsair 450w would be better suited to your system, unless you plan on upgrade the rest at some stage, where you might require a bit more power.

To confirm the compatibility a quick Webnote to OcUK should do the trick.

I hope it didn't take anything out with it.
 
I think you were unlucky.. Most PCs run on just generic PSUs. It's only the enthusiast or server market that use the higher rated PSUs even then, there is no guarantee that branded products will last. I have just raised a second RMA on a Asus mobo, I have had two ISBM/Hitachi HDD go in as many years and sent back a pair of OCZ memory sticks a few years back.

The only thing I see as a disadvantge of a generic PSU, is their efficiency, which is a lot less than a branded model, such as the Corsair.
 
I too really hope its not blown anything else or this could get really expensive. I'll soon find out when I get a new PSU. So fingers crossed.
I completly agree that I was unlucky but i dont think i can take the chance on another cheap and cheerful PSU. Would rather spend £20 or so more and get one that wont hopefully go bang within two years. Well hopefully :)
