Possible power supply problem, Major help needed!

Hello!
Okay so some relevant system specs:
i7-920 CPU (max of around 130-140W)
eVGA GTX 260 core 216 GPU (max of around 200W and asks for 36A on 12V Rails and 500W min recd)
Antec Earthwatts 500W PSU (2 12V rails with 22A on each)

My earthwatts psu, apparently wasnt enough for my setup.
I had issues with random system restarts while gaming.
Not 100% sure its the psu, but i'm guessing it is.
After being driven completely mad, I struggled a bit but finally got newegg to RMA it for me.
I'm leaving for finland in 2 weeks.
I need to get a new psu before i leave because the RMA window will be closed the day i leave!

The new PSU needs to be this size:
(All below are the same in INCHES, CM, AND MM)
- 3.39" (H) x 5.91" (W) x 5.51" (D/L)
- 8.6cm (H) x 15cm (W) x 14cm (D/L)
- 86mm (H) x 150 (W) x 140 (D/L)


It needs to be almost exactly that size or it wont fit, as its going into a dell case.

I've thought of a few choices.
OCZ StealthXStream 600W
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
I like it. It has 4 12V rails, with 18a on each. So since i cant just add 18, 4 times. How much would that leave for my GTX 260 video card?

Corsair VX 550watts
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
It has 41A max on a single 12v rail. So it should be great for my gtx 260. Right? Also the 550w should be enough, however, my antec earthwatts "should" have been fine too.

I've also gone through some other options, but those are the two im really looking at right now.
Thanks SO much for the help :D

I would run memtest first an each of your ram sticks, one at a time. Pc power and cooling makes a replacement ps for dell cases, and they're a good brand. Newegg had one for around $60 recently with 40 amps on a single 12v rail.

+1 for running Memtest to check your RAM first.
Also, give your CPU a quick check with prime95 just to be sure.
If you have anything overclocked, try running it at stock and see if the problem persists.

I would be surprised if your Antec Earthwatts 500w is at fault.
It is a high quality PSU and should have no issues with your rig.

If you must get a new PSU now, I would would either go with the Corsair 550w or the comparable PCP&C or Seasonic model.

I've tried doing memtest.
It's not the memory.

I saw that PCPower PSU
Are you refering to this?

I think you are, but its only 35A on the 12v rails.
Otherwise i'd love to get it. If it had 40A

CPU is fine, i've done prime95 already.
I've had this problem for a long time so I've tried almost everything and the 2 most likely culprits are the PSU and my video card.

So i'll get a new PSU and if that doesnt work out then ill rma the video card.

The thing about the Earthwatts is that even though its a good psu and has 500W, it has 22A on 2 rails.
I dont know how much of that is actually going through the PCI-E connectors.

Appreciate the help!

I would go for a 750 w - this will give you loads of head room and for expansion too. OCZ or Corsair are good ( some people dont like OCZ but ive never had trouble with them )

I would love to Hellboy. What you need to understand is that finding anything above 600w for my required dimensions is hard.

If you refer back to my first post, you'll see the following:

My dell case is rather small and if the PSU is not that size, it simply won't fit without major modification.

Ah sorry was to interested in getting you a better powersupply that looking at the dimensions..

I would go for the Corsair then..

Its a shame you couldnt go for a bigger wattage as its is well within the reach so it runs cooler than a struggling smaller one..


Sorry I ignored your dimensions :(
