Power Supply Issue(based On Intel Core I7-3770k & Nvidia Geforce Gt 730 Ddr3)(critical)

hallo everyone, i recently visited on this website for psw calculator
http://www.coolermaster.outervision.com
and, put this information as described below:-

System Type: 1 physical CPU

Motherboard: Desktop
CPU Brand: Intel

CPU Socket: Socket LGA 1155
CPU: Intel Core i7-3770K 3500 MHz Ivy Bridge

VGA Brand: NVIDIA
Video Card NVIDIA GeForce GT 730 DDR3, 64-bit
Optical Drives: DVD-RW / DVD+RW Drive : 1 Drive
Blu-Ray Internal Drive : 1 Drive

Hard Drives: SATA 2 HDDs

and when i put all those info and calculate to see, how much power i need, this message shown on site below:-

"Your Recommended Minimum Power Supply is 281W"

and, it shows also some cooler master recommended 450W and 500W power supply results.

is it okay with the configuration i described? i'm not sure even about that.

(my old cpu configuration actually is:-

CPU: Intel Pentium G2010 2.8GHz Dual-Core Processor

Motherboard: Intel DH61WW Micro ATX LGA1155 Motherboard

Memory: PNY Electronics DDR3 4GB

Storage: Seagate Barracuda 1TB 3.5" 7200RPM Internal Hard Drive

Video Card: Zotac GeForce GT 610 2GB Video Card

Case And Power Supply: iBall i9090 with SMPS(AC 230V)

Optical Drive: HP DVD1265I DVD/CD Writer)

and i want to change this configuration with this one i built (pcpartpicker.com reference):-

(1) Intel Core i7-3770K 3.5GHz Quad-Core Processor(SR0PL,BX80637I73770K)(QTY: 1) replacement for existing intel pentium G2010 processor

(2) ZOTAC NVIDIA GeForce™ GT 730 4GB DDR3 64-bit Graphics Card(ZT-71115-20L/ZT-71108-10L)[QTY: 1] replacement for existing zotac GT610 DDR3 2GB Graphics card

(3) Seagate Desktop HDD 4TB 3.5" 5900RPM Internal Hard Drive (ST4000DM000)[QTY:1] add with existing seagate 1TB HDD

(4) Lite-On IHBS312-98 Blu-Ray/DVD/CD Writer[QTY: 1] add with existing hp dvd writer

(5) Deepcool GABRIEL 61.9 CFM CPU Cooler(QTY: 1) add with intel i7 3770k processor

(6) Cooler Master Elite 311 ATX Mid Tower Case (RC-311)(QTY: 1) replacement for iball i9090 case with power supply

now, i'm confused for choose power supply max wattage, so tell me which one is better, 450W or 500W?

 

Wattage is only part of the story. Unfortunately, not all power supplies are quality, so you may have a power supply claiming 500W, yet be of such poor build, a lowly 350W may be a better unit. A good 500W unit should suffice, but going up to 600W wouldn't be bad in the interest of future expansion or just leeway.

As a general rule, any power supply that comes with a case is garbage: they're a bottom of the barrel unit. It may seem like a good deal until you realize a quality power supply runs about as much as those combos. Cooler Master is OK on power supplies, but they're inconsistent. Unless you've read a comprehensive power supply review (as seen on JonnyGURU, HardOCP, PC Perspective, etc.) that vets it, I'd move away from it. Buy a new case if you like, but don't cheap out on the power supply. A general list of companies to look at include Seasonic, Antec, Enermax, Silverstone, XFX, beQuiet and Thermaltake (specifically the Toughpower line). I've never seen a bad review of Seasonic, but in general the other brands tend to be overall solid choices. There are a lot of models out there, so if you're not sure, ask. Also, keep in mind that the cheapest thing (barring a sale) is probably not going to be a quality unit, so don't try to skimp here.

 

so, will choose 350W PSW will ok? 'cause i've got lot of recommended suggestion of 500W PSW On other sites.
but, it'll okay if i go with low wattege PSW for good as u suggested....
@Big B

 

That makes absolutely no sense unless you are buying very cheap one (means: used one). LGA1155 platform has been obsolete years now and absolute maximum price for that processor is about 200 dollars. Anything more is total waste.

If you want new i7 processor, you need new motherboard also. Welcome to Intel pricing policy.

Recommended suggestions always have many extra watts. That system will work even with 250W psu, but I'd still take at least 350W one. Just remember to consider processor again.

 

And there's the trick. There are three major lines (also referred to as rails) coming from the typical unit: +3.3V, +5V and +12V. In the past, the 3.3 and 5V lines were the heavy hitters until the introduction of the Pentium 4. That's when a shift towards a higher use of the +12V rail was used, and now your major parts run off them: CPU, video cards (including the power connector on some) and hard drives. A Pentium 4 era unit may have a +12V line with 22A, which was fine for that day, and may have been a 350W unit. Today, you're more likely to see a 350W unit with 30A on the +12V rail while at the same time seeing less amperage on the +3.3V and +5V ones. It's not just one level of power being put out.

Wicked Mystic is right that a 350W is probably fine for what you need, assuming it's a solid unit.
Now, the 730GT isn't a powerhouse, but what if you move to a power-hungry 960?
What if you want to overclock your CPU?
A 350W power supply may not cut it anymore. Sure you can go really, really low, but you may not want to. I don't need a Ford Excursion SUV, and most people don't need a 1500W power supply either. At the same time, a Smart Car doesn't cut it either, or in your case a power supply that cuts right to the edge. That's why you might want to consider something in the 500W range versus just sticking with the 350W. I do like those PSU calculators, but for practical reasons, not every measurement is spot on. It's better to have more room, in my opinion that to run short.

 

ok, which models are best suit for the spec i descripted(based on Cooler Master Elite 311 ATX CPU Case?

and i have to say sometghing. i can't buy gtx/radeon series card 'cause i didn't got any compatible gtx/radeon series GDDR5 graphics card for this motherboard. the Intel dh61ww had a limit of support graphics card is pci express 2.0 bus maximum.

and beside, my rig is build for currently only for personal work, not for gaming!

but ya, i'm planning to build a gaming rig with geforce gtx/amd radeon separately soon.

@Big B

 

That's incorrect info. Any Pci express video card should work fine.

 

The RAM on a video card has no bearing on what RAM works on a motherboard.

What work are you looking to do with this system? Depending on what you do, the graphics provided on the CPU may already be sufficient and negate a need for a discreet card.
Also, how much were you looking to spend on this upgrade?
