Is this a "good psu"? Adequate for which GPU?!

post #1 of 21
Thread Starter 
I need help figuring out if my PSU is any good.

http://www.newegg.com/Product/Product.aspx?Item=N82E16817159079

I am currently running a Radeon 4870, and I am considering to buy a GTX 480 or GTX 460.

The output according to NewEgg is...
+3.3V@24A, +5V@24A, +12V1@18A, +12V2@18A, +12V3@15A, -12V@0.5A, +5VSB@2.5A

I have no idea what it means, so can someone explain to me if it will work with GTX 480 and if it is even adequate for my current Radeon 4870?

Stay away from Coolmax PSUs, it only has 3 eggs for a reason. I never could understand why people want to skimp on the quality of the PSU. They will get a $300 GPU and try to power it with a $30 PSU.

Stick with Antec, Seasonic, PCP&C, Corsair, and some of the OCZ models. I would recommend the Corsair 600w.

This! Get a good quality PSU.

I'm really happy that I bought a Corsair VX550W 4-5 years ago and it's still running in my sig rig smile.gif

EDIT: Used to run a GTX 560ti in it as well.

man trust me that PSU is a pecie of junk and not at all worth it its barely a 500watts PSU note that it have only about 480watts on +12v
here this is the cheapest you should except
Antec EarthWatts EA-650 GREEN $54.99 after MIR
or if MIR is fine then
OCZ ZS Series 750W $49.99 after MIR

CX600 isn't very good either.

OP, Big difference between the GTX 460 & 480. 480 uses alot more power, and has alot more firepower.

Single GTX 460?
Hive 550 $60
Seasonic S12II 520 $74 Shipped.

Single GTX 480?
EA650 $65. $55 after MIR.
Hive 650 $80

Hive series is alright, same as the OCZ ZS. I'd prefer the Antec & Seasonic over them if it was me. Affordable modularity is nice though.

- plenty of other good PSU options out there, these are on the affordable end though.

My Antec 520 managed to power my GTX 480 with an i5 2500k both overclocked heavily including extra voltage. I do think the AMD CPU might use a bit more power than an i5 2500k, but I think 500+ watts from a good brand is enough to run a GTX 480 with almost any processor. My PSU doesn't get hot or have any issues and I can never hear the fan speed up. Of course I do run a G850 normally, but I noticed the i5 2500k didn't seem to push it noticeable harder.

Yea you're right. I think the EA650 is a winner just because of it's price and wattage and build quality regardless. Only flaw with that unit IMO is those nasty cables.

What voltage did you have your 480 at and could you bench it on the Neo 520?

Do I still have to upgrade my PSU if I buy the Radeon 6850 (which btw consumes 25w less than my current GPU)?

I had the GTX 480 at 1.138V clocked at 895, i5 2500k at 1.3V 4.7GHZ and the system ran totally stable with Furmark+Prime95.

Edit: Technically speaking the supply you already have puts out enough power to run a GTX 480, but under heavy loads that low quality unit is likely to fail long term. That's why even if you decided to keep the same GPU we would still suggest grabbing a new power supply....

Long term! Great, so for now will it work? Any risks for at least trying it?
I know I am going to have to upgrade it anyway, but for now considering my budget I can't get a quality PSU (above $50).
