Should I go for this one instead? CORSAIR CMPSU-400CX 400W 12v@30A, single rail
How can I find out what "atx?" version my computer case is and if the psu will fit?

Hi again :)

I've been looking for a more powerful PSU since my current is only 300watt and that's too weak for future upgrades. I have a couple questions.

Some PSUs come with a 20+4pin connector and an 8pin connector. My mobo requires a 24pin(this would use the 20+4) and another 4pin separately, so will the 8pin work on the 4pin mobo slot? I heard that some 8pins detach to make 2x 4pins, but does this apply to all 8pins?

Here's the PSU I found for a cheap price:
COOLMAX 600W 140MM LED FAN
(The website doesn't list the specs or serial number, but I couldn't find any other model on google except this one, it lists the specs:
COOLMAX VL-600B 600W )

Could you tell me if that PSU is reliable enough? I'm not looking for something to last 5-6 years, something that'll last around 2 or so.

Additional info about my pc:
My pc: Gateway GT5064
My mobo: Intel (Cortez G2) 945G Viiv Motherboard
Other info: x1 Sata HDD, x1 DVDRW rom, (Radeon HD4670 video card, buying it soon)

PS: I can't buy online, no credit card etc, so I'll have to go in store. If that PSU is utter doo doo, could you spot a better one (under $70) on this list:
Store 1
Store 2

About the dimension of the PSUs, it's universal size right? I shouldn't worry about it not fitting inside my case?

Thanks again.

ATX 2.xx are all the same physical size.

Your second link does not work.

The 600W Coolmax you linked to has 3-12V rails. You should find a PSU with 1-12V rail. In the specs it will say +12V @17A or something like that. If it has +12V listed twice or three times or more then the PSU has multiple 12V rails. These are being cleared out so they may be cheap. You could probably use it though.

Depends on how tight cash is.

Hmm, link works fine for me: http://www.newegg.com/Product/Produ...

Here's the rails outputs:
+12V1@18A
+12V2@18A
+12V3@15A

Doesn't look so bad, my current PSU only has 1-12v@17A

What's so bad about multiple rails?

Ok, just read this article about rails being locked and power wasted.

Should I go for this one instead?
CORSAIR CMPSU-400CX 400W
Single rail 12v@30A
How can I find out what "atx?" version my computer case is and if the psu will fit?

Are u planning to upgrade later? Single +12v rail @30A is a minimum and yes its good for your current system but i recommend single +12v@41 or more(i think i saw one on newegg and its corsair with 550w)

I'll probably buy a better desktop later on, not any time soon though. I rarely play games on pc, just getting ready for a couple releasing soon. I'll buy the 400w for now.

Thanks.

Could someone answer the other questions?

"Some PSUs come with a 20+4pin connector and an 8pin connector. My mobo requires a 24pin(this would use the 20+4) and another 4pin separately, so will the 8pin work on the 4pin mobo slot? I heard that some 8pins detach to make 2x 4pins, but does this apply to all 8pins?"

and how to find out what atx version your case is?

What i think is u can remove other 4 pins and use 4 pins just like 24pins and u can remove 4pins and use 20pins.
