Assembling a PC -- Head Here


AtheK

Recommended Posts

This is what i'm gonna go for :

 

Phenom 9850 Quad-Core Black ED (Is the black edition special or somethin?)

ASUS MB with normal 8gb ram support

4 gigs of ram

500GB HDD

And card....ATI 4670 Or 9600gt (4670 if budget gets a down)

what do u think abt the config.....a fair entry or sub-entry level gaming pc?

 

Also wanted to ask.....Is a 450w smps enough for 96gt?

 

Edit: Does an E8400 outperform Phenom 9850?????

Power Supply Myths Exposed!

 

1. DOES A POWER SUPPLY UPGRADE MEAN A HIGHER ELECTRIC BILL?

This is the biggest myth of all. First, it's important to understand that a power supply only delivers the power that's needed by the system, nothing more. If your PC currently has a 400W supply and the system needs 350W, it will still need and use only 350W - if the only change is upgrading to a 500W power supply (the upgrade makes sense since there are many advantages to running a power supply at a lower percentage of its rated capacity). Whether the electric bill goes up or down is solely determined by the efficiency of the new power supply. Greater efficiency means a lower electric bill because more of the AC power is converted into DC for the computer, rather than wasted as heat. The savings can really add up over time. For example, when the money saved in electricity over the course of its 3-year warranty is taken into account, the purchase price of the efficient Silencer 750 is less than $0.00. Here's the math:

 

Model Efficiency @ 550W Input Power @ 550W

Silencer 750 83% 662W

Antec True Power 550 73.8% 745W

 

For the same output power, the Silencer 750 uses 83W less input power.

 

3-year savings = .083KW x $0.10/KWH x 24 x 365 x 3 = $218.12

 

 

--------------------------------------------------------------------------------

 

2. DON'T BE MISLED BY EXAGGERATED WATTAGE CLAIMS

To properly compare power supplies, wattage claims must state the maximum ambient temperature for continuous, full-load operation. Unfortunately for the consumer, this information is usually withheld, opening the door for manufacturers to exaggerate their wattage claims. They do so by assuming an unrealistic ambient temp of only 25°C (77°F), even though the actual internal power supply temp is at least 40°C (104°F). Since the proper full-load rating is 15°C higher for home use and 25°C higher for industrial use, these power supplies produce 33%-50% less power than their advertised ratings. See the derating chart on the right.

 

Elevated Temperature Testing

 

 

 

Turbo-Cool 510 spec: full load @ 50°C.

"500W" Home PSU spec: full load @ 25°C, no load @ 70°C.

 

--------------------------------------------------------------------------------

 

3. DON'T LOSE POWER WITH MODULAR PLUGS

Due to their look, convenience, and cost savings for manufacturers, modular plugs have become a popular power supply feature. Unfortunately, there has been little or no discussion of the impact of this feature on overall performance and reliability. The fact is, modular plugs limit power by adding to electrical resistance. The voltage drop can be as much as would occur in 2 feet of standard wire. Worse yet, modular plugs utilize delicate pins that can easily loosen, corrode, and burn, creating the potential for a major system failure. That's why professional system builders specify uninterrupted wire!

 

 

 

--------------------------------------------------------------------------------

 

4. MARKETING MYTH vs. WARRANTY REALITY

As with all consumer products, the fine print in the warranty will often contradict a manufacturer's marketing hype. Unfortunately, this is especially true for computer power supplies. Take for example this quote direct from the product box of a leading manufacturer: "we've earned a stellar reputation for producing stable, reliable, industrial-grade PC power supplies". Now compare that statement to what is specifically excluded in the company's "legendary 3-year warranty":

 

Sample of What is NOT covered -

 

a. commercial and industrial use

b. wear and tear from moving parts

c. that the product will meet your requirements.

 

In conclusion, don't be mislead by marketing hype, avoid superficial gimmicks, and read the warranty carefully before purchasing your next power supply.

 

 

 

--------------------------------------------------------------------------------

 

5. AN SLI CERTIFIED POWER SUPPLY WILL ALWAYS POWER HIGH-END GRAPHICS CARDS?

We went through three power supplies before we found one that consistently worked with these high-end graphics cards and an FX-60. We initially started with a Silverstone 600W SLI certified power supply, but running some games resulted in the system powering down under full load. We next moved onto a higher rated Thermaltake PurePower SLI certified 680W unit. But while most games ran most of the time, the system would still occasionally shut down. Finally, we ended up using PC Power and Cooling's massive TurboCool 850 SSI. This just goes to show that if you really want to build something that pushes the bleeding edge, make sure you have the right power supply.

6. SHOULD AN ATX POWER SUPPLY BE COOLED WITH A 120MM FAN?

Most low-noise ATX power supplies today utilize a top-mounted 120mm fan rather than a rear-mounted 80mm fan. The 120’s favorable reputation is based on the fact that under low to medium load conditions, the 120mm fan provides sufficient cooling at low RPM and low RPM fans are generally very quiet.

 

However, problems occur with this design when the load exceeds 50%-60%. Because the 120mm fan consumes about 1.5” of vertical space inside the PSU, heat sinks, capacitors, and other components are about 30% smaller in height compared to a PSU with a rear-mounted fan. The smaller parts can handle less current, so the maximum power available with the 120mm design is limited. And, because the heat sinks have less surface area, more air flow is needed with this design to keep the thermal situation under control. With 80%-100% load, the 120’s fan speed can double and the noise level can jump by up to 20dB.

 

In conclusion, for systems that require more than 50% of the power supply’s capacity, a well-engineered PSU with a rear-mounted 80mm fan will provide superior performance and reliability (due to larger components) at a noise level comparable to a PSU equipped with a 120mm fan.

 

 

--------------------------------------------------------------------------------

 

7. ARE TWO POWER SUPPLY FANS BETTER THAN ONE?

No. A power supply with two fans doesn’t exhaust any more air from the case than a power supply with one. That's because due to space limitations, only one fan can be used for exhaust, while the other is limited to spot cooling. Possible explanations for a 2-fan PSU include: thermal engineering problems; an attempt to exaggerate the wattage rating by spot cooling the transformer; or an attempt by the marketing department to create a new gimmick.

 

 

--------------------------------------------------------------------------------

 

8. ARE MULTIPLE 12-VOLT RAILS BETTER THAN A SINGLE 12-VOLT RAIL?

With all the hype about multiple 12-volt rails (ads claim that two rails is better than one, five is better than four, etc.), you’d think it was a better design. Unfortunately, it’s not!

 

Here are the facts: A large, single 12-volt rail (without a 240VA limit) can transfer 100% of the 12-volt output from the PSU to the computer, while a multi-rail 12-volt design has distribution losses of up to 30% of the power supply’s rating. Those losses occur because power literally gets “trapped” on under-utilized rails. For example, if the 12-volt rail that powers the CPU is rated for 17 amps and the CPU only uses 7A, the remaining 10A is unusable, since it is isolated from the rest of the system.

 

Since the maximum current from any one 12-volt rail of a multiple-rail PSU is limited to 20 amps (240VA / 12 volts = 20 amps), PCs with high-performance components that draw over 20 amps from the same rail are subject to over-current shutdowns. With power requirements for multiple processors and graphics cards continuing to grow, the multiple-rai l design, with its 240VA limit per rail, is basically obsolete.

 

PC Power and Cooling is once again leading the industry. All of our power supplies now feature a large, single 12-volt rail. The design is favored by major processor and graphics companies, complies with EPS12V specs (the 240VA limit is not a requirement) and is approved by all major safety agencies such as UL and TUV.

Mobo : ASUS-M2AVM or M2A-H/HDMI(again suggest me a better one if possible)-5k

 

RAM-4 gb Transcend DDR2 800Mhz-2300(Same as above)

 

GPU : XFX Radeon 4850 -9300(I know this is the Best GPU for the price)

 

HDD: 500 GB Seagate-3k

 

Monitor: Entry level Samsung monitor(20 '' 933 SN)(ANy better ones?????)-7700/-

 

Cabinet: Zebronics Gaming cabinet(Not decided on which)-1.7k

 

SMPS- Cooler Master Extreme Power 600W-4k

 

 

Please feel free to make your suggestions guys. I only want the best performance for my money(Who doesn't?)

 

 

Thanks,

 

 

Sriram

Good system all around. Cant say too much on the AMD front (Intel man this gen) but everything else looks good.

 

You wont really need a Mobo with HDMI since you will be connecting the display through the GPU so keep that in mind.

 

Also if you can stretch your budget a bit I would say go for a different display. There are a lot of decent 22" LCDs in the 13k range.

 

Edit Actually having given the procyy a look you would be better off with a E8400. Look here.

Guys...I need a Gaming cum Home Theater PC for 80k.

I would need all components....Let's say i have nothing presently(Not even a keyboard and mouse)

I need my PC to service me well for at least another 2-3 years.

One thing i wouldn't compromise on is graphics.

I don't do any other heavy work on my PC.

 

 

What would you suggest me??

 

Thanks in advance.

Thanks dude for the configuration but......

Yaar it is coming to 86k without even the HDD and the Speakers.....this is a 1L configuration....

What do you suggest with the speakers??

 

Plus i need a better monitor.

I was considering spending around 20k on the monitor and get the Dell 24'' Full HD one........or the IPS paneled 22'' one............

I think i'll have to cut on the processor.

If i say go for a Intel Quad,What would be the new configuration??

You can cut 12k by not going for i7 proc and supporting board...but then you will need to get DDR2 ram also....so you can save like around 20k in that....i totally forgot HDD put a 500 gig...should cost you 3.3k

^^^Thanks again,bro.But some new queries have sprung up now!!

So if i go far a Quad and an equivalent motherboard........It won't make a hell lot of difference right on the speed??

And can i still expect it to run for another 2 years.........?

 

 

And what do you suggest regarding speakers??

well i7 is the latest procs...but saying that the Quads are pretty good as well...i7 doesn't give you a definitve edge in gaming so yes...go for quad...

 

Cut down on the cabinet you dont need to spend 7k on 9000 then you can get a thermaltake or a CM.

 

For speakers if you can stretch the budget a bit pick Z5500 they are very very good speakers will cost you around 15k though.

 

Yes it should last you 2 years...

if u r into music and dont care much about surround sound and sh*t.. go for Altec Lansing Mx5021 (6.5k) and pair them with Asus Xonar Dx (3.6k) ..

 

yeah right now core i7 doesnt show much of improvement over 45nm quads and imho q6600 is still the best quad to get provided u can procure one , coz it overclocks like crazy ..

^^I am not really into overclocking and sh*t........Actually,I dont think i know how to OC...............+ i have heard if you OC you further need to provide extra cooling and crap..................

 

Yeah...5.1 wont even fit on my desk..........SO i guess the 5021 should be good enough for me......

Else i think ll go for 5k headphones...........!!

Athek, I would like to differ. I made the same mistake the previous gen and I'm still stuck with an SLI motherboard which only supports 400 MHz DDR memory.

 

I would suggest he go for the Core i7 coz soon everyone would be transitioning to DDR3 and higher mem clock speeds and he would be stuck with the previous gen hardware. If he decides to change then, he'll have to again end up changing proc, mobo, and the mem. This is the right time for him to take up the new gen hardware. Also, you suggested 4 GB mem for him, this will not help since i7 works on triple channel and he'll either need 3 GB (1x3), 6 GB (2x3), 9 GB (3x3), or 12 GB (4x3) to make full use of the proc and it's integrated memory controller.

 

I would suggest he go for one of the Corsair 3 GB mem kits for about 8k. Once the prices drop, he can go for another 3 GB for a total of 6 GB working in triple channel. This would be a totally kickass setup.

^^^^But bro....It's really getting out of budget.................i can't spend 1 lakh on a desktop..........!!!

 

Isnt there a cheaper motherboard to go with the i7 ????

 

And if i go for the i7 ill have to compromise on the grfx card and get a 10k 512MB ATI 4850.

How long do you think that'll last me??

hmm... there is one Gigabyte mobo but it's just another 2k less. I would suggest you stick to the MSI as it has better features and it supports a total of 24 GB mem with 6 slots. Since you mentioned HTPC, i didn't read that previously, I presume you have a good TV already??? If yes, then the monitor cost can be curbed.

Guys there is a Dell Studio XPS PC.........it has everything i need except that i only has a 512MB ATI 4850...........They haven't mentioned the motherboard on th site so i don't know about that............And it's priced very decently as welll only.........80k

 

My question is:::

 

Once it arrives will i be able to add another 4870 to it in crossfire configuration???

I mean this sort of thing is possible in pre-assembled PC's right.

 

PS::Sorry if it's a noobish question.
