Do amps matter?

[BoomasuresRex]

so im looking into getting a new power supply so i can get a new video card the one im looking for is the "CORSAIR CX series CX600 600W ATX12V v2.3 80 PLUS BRONZE Certified Active PFC Power Supply" and it says it has out puts "+3.3V@25A, +5V@25A, +12V@46A, -12V@0.8A, +5VSB@3.0A" and i was looking to see if out puts matched what i have and i have the same volts just not the same A (which im guessing is amps) and so i dont know if it will work please help, thank you.

they matter as you need enough of them on certain rails to power those parts, most notably the GPU. With a brand like corsair I wouldn't worry about it. What are your system specs?

 

[Dark Lord of Tech]

The CX , VS , and RM series all use poor capacitors , look for a SEASONIC , XFX , Antec , Corsair AX or HX series.

i was also looking at
"CORSAIR Enthusiast Series TX650 650W ATX12V/EPS12V 80 PLUS BRONZE Certified Active PFC High Performance Power Supply"
just a little more expensive and im already pushing my budget can you elaborate on what makes them bad?

i need at least 600 the card im looking on getting needs 550 and i dont want to get that close so im going to have to say no on that one.

 

[woltej1]

the corsair TX will suit your needs and as of right now your system does not seem to need a lot of power.

ok but will the out puts work with a 660 ti video card is my next question and that needs 550 watts of power.

 

[woltej1]

yea, it'll handle a 660ti just fine, by no means is that a demanding card.

 

[Dark Lord of Tech]

What card are you getting?

 

[BoomasuresRex]

ok you seem to know what your talking about. will the 660 ti be able to handle newer games at high to medium resolution?

 

[Dark Lord of Tech]

The XFX 550W will run a system with a 770 , IT HAS 44 AMPS ON THE 12 V RAIL.

speaking gibberish to me man can u rephrase please?

A Geforce GTX 660ti needs at least 24 amps on the 12 volt rail and a 450 watt power supply , The XFX 550 watt linked above , has 44 amps on the 12 volt rail , more than enough for a 660 ti.

 

[woltej1]

graphics card run off the 12v line of a PSU. There needs to be a certain amount of current through this to support certain graphics card. he is stating the the XFX has enough current to support a 770.

ok ill consider but ill probably stick with the cx just cause its cheeper and it can handle the 660 ti as well ( at least i think it can)

 

[Dark Lord of Tech]

Plus the XFX 550w is OEM sized and a good fit for a prebuilt.

5.5" x 5.9" x 3.4"

ok back to my original question will the cx work for my computer?

its the same size as the cx i just dont understand why think its that much better and idk where you got 400 watt for a 660 ti everywhere ive looked its been at least 500 .

but then again theres a good chance im wrong

 

[Dark Lord of Tech]

Yes , it's not the same quality of a XFX but it's OEM sized and will easily power a 660ti.

Hope this helps , have a great week!
