Hi guys
I'm thinking that my current power supply doesn't have enough current / power for my system. At the moment it has a 370W High Power brand PSU (http://www.highpowersupply.com/hpc370n12s.html from my previous build.
Currently I'm running:

GIGABYTE GA-M57SLI-S4
AMD x2 4000 @ stock
2 *1gb DDR2 800 ram
Pioneer IDE dvd rw
XFX 8600GT
1 * sata 320gb and 1*ide 320gb
wireless keyboard/mouse

I'm thinking if I put in a better graphics card or another hard drive it might just be running out? It has a 14A and 15A 12V rails.

If I do need another one, could you recommend one from this website:www.tastech.co.nz because I'm in New Zealand and that is the cheapest store in my city.

Thanks everyone!
 
21amps on the +12V I would get another PS. What's your price range on spending on a new PS?

Hoping to spend under 150$ if I can help it. Is it ok to have big amps on a single rail though?
 
Either the Corsair, Seasonic, or Silverstone that are listed on the website.
 
With your setup, you can easily go under $100. Are you planning on using the PS for a future build anytime soon? You can go with the Corsair line of PS. Don;t buy from NewEgg.com. Since these are popular and many people buy these, NewEgg charges alot nowdays on Corsair PS. Look at Buy.com for Corsair PS

Prices of Corsair PS on Buy.com

VX450 - 33amps on the +12V for $60
VX550 - 41amps on the +12V for $65
HX520 (modular) with 40 amps on the +12v for $90
HX620 (modular) with 50 amps on the +12V for $115
TX750 with 60 amps on the +12v for $115

Among this group, the VX550 for the price and amps it puts out on the +12v would be good for you. This is almost double the amps you have on your current PS at only 21amps.
 
Is it ok to run that many amps on one rail though? I thought you weren't supposed to go past 20A? Also, what about Enermax? I was thinking the 535W one on that website and was looking at the NZXT Alpha case to go with it. Any thoughts on that case too? The only seasonics in my price range for that is the 500W and 430W which are both very cheap so maybe bad? Just looking up the silverstone one now it's the 560W one

Thanks very much guys

The ones I listed are all very high quality. You can have more than 20A on a single rail without any problems. All the modern PC P&C PSUs are single rail and the 1200w one has 90A on the 12V line. You really don't need that much power for your system anyway, so the 430w Seasonic will be more than sufficient. Quality over quantity...
