Mercury AP-2400

Voltage 115/230 V
3.3V 5V 12V
20A 14A 14A

Current
10A/6A
+12V -12V +5V
13A 0.3A 2.5A

These are the specs of my 400W PSU. See sig. for sys. specs.
I want to OC the HD 4850 too, so would like enough power for that.

Is this PSU enough?

Should I get the HD 4850 512MB or wait for the 5xxx series?

I think ocing the HD4850 is out of the question, i,m not even sure if your psu can handle a stock HD4850. :s

No, your PSU will die a fiery death.
You need a QUALITY 450w+ PSU from Corsair, PCP&C, Enermax, Seasonic or the Antec Earthwatts line.

450 Watt or greater power supply with 75 Watt 6-pin PCI Express® power connector recommended (550 Watt and two 6-pin connectors for ATI CrossFireX™ technology in dual mode)

A 4850 will be much, much better than your current 8600GT.
As cheap as they are now, why put off the upgrade.

I just want to reiterate how bad your current PSU is.
The Mercury website no longer has your 2400 PSU listed but it's next of kin, the 2450, only has a 65% efficiency rating!! Even if you do not upgrade your GPU now, you really need to get a better PSU. The one you have now is a disaster waiting to happen.

True. Even the HD 3850 is twice as fast as the 8600GT in most benchmarks I've seen. The HD 4850 would be just incredible compared to that. The 8600GT is just not a gaming card.

If you need a decent PSU for as little cash as possible, the StealthXStream 600W is $50 after rebate and shipping.
