Hello DJready;

What make and model is the PSU?
It should have more than enough power to run all your parts.

This is interesting - and not very good news for you. You'll need to seriously think about replacing your PSU.

If the people over @ Guru3D are correct:
Jewel Black SP-ATX-420WTB-PFC-1 has only about ~15Amps +12V.

That is really low (and I mean REALLY low) amount of +12V power for a 420W PSU. Something we'd expect to see in a 300W PSU. For a decent 420W PSU we'd expect to see 24Amps or higher for +12V.

Here is a budget $25 300W PSU: FSP Group ATX300-PA 300W
And it has 22Amps of +12V. (12V1+12V2=264watts Max / 264watts divided by 12volts = 22Amps)

The Corsair CX400 will be able to handle your rig adequately.. Don't count on your current PSU.. WR2 has explained everything properly anyway..

uhm, i just wonder why does most PSU that are even 500 or 600 watts have 15-18Amps +12?

Where i live that Crosair CX400 is 76 euro/96$

Likely you're not reading the data label correctly.
What is your budget for a replacement PSU?

Can you find an Antec EA-380D for a decent price? It has 28Amps +12V.

Don't forget you can look up the the +12V total power for lots of different PSUs in that link in my 2nd post.

I would recommend getting at least a 650w or 850w and any Ultra or Silverstone Stryder 650-850 will work.

I recommend Silverstone and Ultra for anyone that is into PC gaming.
