Building a budget day trade computer

I am currently in the process of building a day trading computer.

I have been out of tune with computers for a while so I came here to get some opinions/advice.

This will technically be a budget build since I am not hardcore gaming or anything like that.

This is the build I had in mind...

Rosewill Challenger Mid ATX Tower (3 case fans)
Logisys 550w PSU
Asus P8H61-M Motherboard
Intel Core i3-2120 (3.3GHz)
G.Skill Ripjaws DDR-1600 (2x4GB)
Asus 24x DVD Drive
LG 22x DVD Drive
Western Digital Caviar Blue 500GB @ 7200RPM
Two Acer or LG Widescreen LCD Dual Display (22/23")

Any thoughts on this build? Also HDD's being so expensive...should I stick with HDD or go SSD?

Thanks everyone!

As for HDD vs SSD, buy a SSD for windows and apps, with a HDD for storage of documents, etc. Just as you have it configured now.

Your build is fine except for the power supply. Logisys is a crap maker. Go with a reputable brand such as Corsair, or Antec, or Seasonic.

Thanks abekl, which power supply would you recommend?

And another question, if I had mobo, ram, psu, would I be able to turn on case fans and psu fans with just that? Or do I need CPU to even get the fans on?

If all your doing is internet explorer, ssd is wasted money. $1+ per gb vs $.10 for an hdd. SSD are for performance machines.

"SSD are for performance machines"

True. Some of the trading apps I've seen are very complex and large - it's not necessarily all web based.

My build will be mostly for streaming a lot of data really fast.

It will be software based.

I'm looking for a decent power supply, since abekl said mine blows lol.
As far as HDD I'll probable just go with a Seagate or WD 7200RPM.
How are thermaltake PSU's and what Kim of wattage am I looking for with my build?


Will PSU fans and Case fans work without a CPU?

Sorry, I've been out of the tech sector for a while lol.

Thanks for all your guys time and help.

Asus P8H61-M Motherboard looks like a mismatch with your plan for 2x LCD monitors.
It only has a single VGA D-Sub monitor port. Also has old school PS/2 mouse/keyboard ports, parallel and serial ports which you probably don't need.

ASUS P8H61-M LE/CSM at least has 1xDVI digtal and 1xVGA/D-Sub analog monitor ports - about the minimum you'd want.

Well it has 1 DVI and 1 VGA, I got it open boxed for $47.
I could just end up getting a video card too I need be.
I'm just trying to figure out what power supply an HDD to get.
I read a lot of reviews on newegg and I guess HDDs are unreliable because people are receiving dead HDDs or ones that stop working after a short period of time.

And also, will PSU fans And case fans spin without a CPU?

P8H61-M. That will work.
It was the P8H61-M PLUS model that was a mismatch.

You're very curious about this question.
Does it have a point?

Trying to test whether or not everything is hooked up correctly, and while waiting for CPU to arrive, I want to see the fans spinning.

I'm also hard pressed to find a 5egg rated HDD..I will only need ~250GB of 7200RPM

thing is with hdd ratings, there are sooo many people who buy them and never report how good they are, genrally you only get the negative feedback. I have only had one seagate drive fail (power got tripped while it was writing and locked the read head). seagate warrantied it anyway.

A spinning case fan and PSU fan will not demonstrate that everything is hooked up correctly.
It will show the PSU is providing power to the fans and that the power switch is hooked up the correct motherboard header.
But if you want to see the fans spin - go for it.

Fans connected to psu or motherboard ?
I'm not into powering the mb without the cpu but you can get things to show you some life by shorting the green wire on the 24 pin connector with any of the black grounds.

My motherboard is an open box Asus P8H61-M, so I just want to make sure everything works, that's why I wanted to test fans.

I am ordering the Seasonic PSU now.
What should I do with my Logisys 550W lol?
I've never returned anything to newegg...would it be better to just keep it as backup or something?

And what HDD would you recommend, I'll only need 250 GB max and don't want to spend a lot for a HDD. But also want to go with reputable brand.

Would it be better to just spend $10 more to get the 500GB?

The fans are the least of your worries.
The fans don't even need the motherboard to work correctly in order to run.

Did you get all the usual motherboard accessories?
The NewEgg photos usually show them.

Got everything but the user manual, but I can just look at that online. So far all I got with the mono is a green sn_pwr light when connected to PSU, but PSU fans and case fans don't spin...

The little green light works off of standy by power that is always on, in order to get the psu to start you need to jump it like I posted in my last response here.

If you have the case hooked up - you might be able to just push the power button.

Thermaltake Power Supply 430W W0070RUC review get a very poor review by HardwareSecrets.
Still, it's probably just 'ok' for your build with your very low power requirements.

not a bad review, but its the purepower 430, they didn't test the tr2 430, just said it was the same thing. Its not. PP is 1 12v rail at 18A, TR2 430 is 2 rails at 14A each.

The tr2 700 passed with flying colors

http://www.hardwaresecrets.com/article/Thermaltake-TR2-...

Can't really expect the best ps in the world for $32.99 (22.99 with mir)

I love HW secrets thermal compound tests ... Diaper ointment doesn't work as good as mayonaise. :sol: 

AS for testing without a cpu, most boards won't power up without the cpu.

It likes to get a signal that there's something at the other end to send power to.
If you have it hooked up to the motherboard and the case switch connected it should work, as long as the psu switch is also on.

It was the correct W0070RUC model review for the PSU you had linked at NewEgg. It's made by HEC/Compucase.

Thermaltake TR-700P TR2 is the model with the good review and is manufactured by FSP.
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Thermaltake TR2 power supply, W0070RU, 430 watt psu

Connectors:
1 x 20+4 pin ATX Power Connector
1 x ATX 12V (P4)
9 x 4-Pin Peripheral Power
2 x SATA Power
2 x Floppy Power

-12V@0.8A
+5VSB@2A
Dimensions:
6.3" x 5.9" x 3.4" (L x W x H)

VS

W0070RUC

1 x Main connector (20+4Pin)
1 x 12V (4+4Pin EPS)
6 x Peripheral
2 x SATA
2 x Floppy
1 x PCI-E
Output Current:
+3.3V@20A,
+5V@24A,
+12V1@14A,
+12V2@15A,
-12V@0.3A,
+5VSB@2A

The RUC is updated and changed over the RU but no one has bothered to test the psu quality itself, just stuck with the old review.

Any time I see a PS with huge power on the 3.3v rail and 5v rail and nothing on the 12v, I run away. Most of the time, thats pretty good indicator of a crappy ps, wich RU was that, RUC is more balanced.

Edit, conserning the OP, here is his logisys spec

•Power Specifications:
•115V, 230V switchable power supply
•+3.3V, 28A
•+5V, 38A
•+12V, 17A
•-12V, 0.8A
•-5V, 0.5A
•+5Vsb, 2.A

huge power for 3.3v and 5v, nothing for 12v. Seasonics look to be pretty good balance for 12v rails.

IMO, its like taking a PII C2 review and saying C3 is exactly the same, just not testing it. But powersupplies are in ample supply, no one wants to re-test all updates to see if they are fixed or not.
