Hello Toms hardware,

I am currently building a new PC and I would like to know the correct wattage for my rig and if the Geforce GTX 550 is the better choice for a GFX card than the GTS 460

Build:
Case: NZXT M59 Gaming Mid-Tower Case with See-Thru Window
CPU: Intel® Core™ i5-2400 3.10 GHz 6M Intel Smart Cache LGA1155
Fan: Intel LGA1156 Certified CPU Fan & Heatsink (I think its the fan that came with the CPU)
Motherboard: [CrossFireX] GigaByte GA-H67M-D2-B3 Intel H67 Chipset DDR3 mATX Mainboard w/ 7.1 HD Audio, GbLAN, 2x SATA-III RAID, 2 Gen2 PCIe & 2 PCIe X1 [B3 Stepping]
RAM: 8GB (2GBx4) DDR3/1600MHz Dual Channel Memory Module
GFX Card: NVIDIA GeForce GTX 550 Ti 1GB 16X PCIe Video Card
PSU: 500 Watts - Standard Case Power Supply
External Network Adapter: Edimax EW-7811Un IEEE Nano 802.11n USB Wireless Adapter

Honestly a Corsair 430CX could run it, but I'd say go for 500-600W range. 600/650W if you might go SLI 550 in the future. That will give you lots of headroom.

Hello Wolfram23,

Thank you for replying, for a PSU would a Corsair or a XtremeGear SLI be the better brand?? I hear that the XtremeGear PSu's give out really fast.

Thank you!

^ That's a GTS 450 :) 

The 550Ti is faster than a GTS 450, but a GTX 460 is faster than both.

Also that PSU calculator is alright but honestly it goes so overboard you can probably use what it recommends and add a second card right off the bat lol. Not that I recommend that, when it comes to power supplies, better safe than sorry.

Hello guys thanks for the input on the graphics cards. I read up on reviews between the 550 and the 460. The 460 seems to have some problems with people and that it requires two 6v connectors. Also Been seeing that alot of people are having defective cards, as well as the cards working great for 2 weeks and then all of a sudden they would die.

That's not true, any GPU comes with at least 1-2 years warranty and the GTX 460 is better than the GTX 550ti (a bit faster).

So what you heard about the GTX 460 is a rumor.

Thanks, I am sticking to a 1280x1084 screen resolution I know it would matter by a little but by sticking to this resolution would the GTX 550 still be faster or would the GTX 460 be? Also wouldn't the 550 be better since it is more new than the 460 by about 1 year?

The 550 Ti will never be faster at stock vs stock speeds, regardless of resolution. Only chance it has it to lower the resolution so much that both cards get CPU bottlenecked, at which point they'll basically be identical (but that's not very realistic usually).

Still, at 1280x1024 (1084??) you should be fine with the 550 Ti since that seems to be the one you really want. The newer model doesn't really mean much to be honest, they didn't implement a whole lot of changes this generation compared to the improvements from 200 to 400 series, and when Kepler comes out that'll be big too since it's a die shrink.

Figuring out how much you need is pretty simple: cpu wattage + gpu wattage + ~100 watts for mobo, ram, hdd, and fans + ~100 for overhead (future upgrades, overclocking, etc).

You selected a 95w cpu, and 120w gpu for 215w. Those parts are 12v, so 215w / 12v = 18 amps (on the 12v rail). Add in the other ~200w, and you'd be safe with a 415w psu that has at least 18 amps on the 12v rail. But, keep in mind you'll need additional amps on the 12v rail if you plan to overclock.

Your system memory is ddr3, but your gpu memory is separate and doesn't have to match. If you're looking for a gtx460 (which I would recommend over a gts450, if you can budget it), add 30-35w and 3 amps (12v rail) to the numbers I provided for your psu requirements.

It's easy. watts = volts x amps. Many times when people are talking about how many watts they need, what they should actually be looking at is amps times voltage, which will tell you wattage. So let's say you need 95 watts (8 12v amps) for your cpu and 150 watts (13 12v amps) for your gpu. That's a total of 245 watts. But that has to be at 12 volts, so what you actually need is a power supply that gives at least 21 amps of power on the 12v rail... or 245 watts. All of this should be clearly stated on the label, and reputable brands will post honest figures. For your other parts, you're not concerned if it's 12v or 5v, as they only need 5 volts. So you figure out how many amps (and therefore watts), you need for your cpu and gpu, and add the total wattage for the other parts (as you're not concerned about amps for them).

To simplify, if you're getting a gtx460, and have a 95w processor (most non-enthusiast models), you'll be safe with a 450w psu that has 21 amps on the 12v rail.

Thanks Hapkido for the long explaination.

I am going to go with a 500watt PSU since it is going to be comming with a case that I am going to get.

Oh and the brand for the PSU that comes with the case is a APEVIA (BLACK) WIN-500XSPX APEVIA 500W JAVA Power Supply is Apevia a good brand?? I cehcked out the other PSu from the same brand on Newegg and the reviews showed that it isn't a good PSU

Also would Wattage still change from 450 watts if I decided to change my PC build CPU from a i5 2400 to a i5 2500? the normal one not the i5 2500k

OK so I am going in circles about the graphics card. Since the GTX 550 and the GTX 460 are just about the same price I would stick with the GTX 550 since I have a friend who is selling it for "cheap". I am giving myself a headache on choosing a GFX card >< since I have Geforce 9500GT DDR2 I just wanted something with alot more power. With that being said would I still be good with a 500watt PSU? or would I have to go for a 600 or 650 watt?
- Also anyone know if the Corsair Enthusiast TX650 is better than the builder series? I have a CX 430 right now and it has been working perfectly. But there is no CX 650 watt only a TX 650 so if I need 600 watts I would go for the CX600.

Oh and a quick question about RAM is it better to have RAM with a high number of GB and have a low number of MHz i.e. 4gb RAM 2000MHz, or 8GB RAM 1600 MHz

Thanks!

gtx 460 is faster than gtx 550. Go with the 460. Don't let the 500 vs 400 naming convention fool you. That indicates what generation it is, not how fast it is. The 460 is faster.

It's better to have more ram than faster ram, to a point. I'd go with 8GB 1600mhz over 4GB 2000mhz. I doubt you'd notice the extra speed, but you'll probably notice the extra amount.

If you would have read my post, I explained why a 450w psu (as long as it 21 amps on the 12 volt rail) is fine for a gtx 460. For example, this psu would work for you. If you look in the pictures, there's a label that shows "+12V 35A". That means the 12 volt rail has 35 amps. It's also stated on the detail screen.

yes the 460 is about 30% faster than the 500 (HWcompare.com) but like I said earlier I havea friend who is selling it for cheap so I would go for it and compared to the GFX card that I have now (9500GT DDR2) the 550 is way much faster than the GFX card that I have now. So I am safe with a 500watt PSU still? since I would go for a 450watt on the 460 and on HW compare the 550 has 40 more watts needed so 500 watts right?

If you already have a Corsair CX430 just use that. If anything, Corsair under rates their PSUs. It'll handle a GTX 460 fine. If you plan to upgrade or get a second GPU in the future then you might need a new PSU as well.

I don't know why you keep insisting that a computer with a gtx 550 needs a better power supply than one with a gtx 460. It's a slower card (read as: uses less power). You could sli 2 460s on a quality 650w psu. It's overkill for a 550. Your money would be better spent saving a bit on the psu and getting a better video card.

For $800, you can do WAY better than a 550.

i5-2500
Biostar h67
Gigabyte gtx 560ti
Kingston 8GB 1333mhz
OCZ 500w 80+
Thermaltake v3

total: $674.94 (before $40 in mail-in-rebates)

That leaves you plenty for a hard drive and dvd burner. You could probably even squeeze a 60GB ssd (~$100) in if you wanted.

Build it yourself. I didn't spend a lot of time looking, and you may be able to find better deals, but what I linked is a way better gamer than what you were looking at from Cyberpower for a lot less money. They have to turn a profit building rigs, but you don't (and putting a computer together is easy), so your money is better spent on parts than labor.

Hmm seeing that building one is way better I might just do that with the sales comming on :D . Also I found a GTX 460 for $100 :D  500Wattage FTW lol. And OMG the GTX 460 I freaking HUge compared to my Geforce 9500GT

I have like no experience as you might have guessed on building computers just upgrading but I guess on the mother board you just screw the board into the case right?

Is there really a performance difference between the i5 2400 and the i3 2120?

Anyone have any suggestions on cheap cases? I know hapkido suggested a case but its around $50, just wanting to know if there are cheaper cases that are the same cooling and "quality". Since there are soo many kinds its giving me a bigger headache than I have now since I am sick ><. Plus he forgot to add the HDD

For motherboards (H67) I have heared that Gigabyte is the brand over Biostar since there are more negative reviews for Biostar's products. and With gigabyte in mind I found 2 H67 Motherboards that are practically the same what is the difference??:
-Gigabyte 6 Series GA-H67MA-UD2H-B3 Intel H67 Motherboard - Micro ATX, Socket H2 (LGA1155), DDR3 1333MHz, SATA 6.0 Gb/s, RAID, CrossFireX Ready, 7.1-Channel HD Audio, Gigabit LAN, USB 3.0
-Gigabyte 6 Series GA-H67M-D2-B3 Intel H67 Motherboard - Micro ATX, Socket H2 (LGA1155), DDR3 1333MHz, SATA 6.0 Gb/s, RAID, CrossFireX Ready, 7.1-Channel HD Audio, Gigabit LAN

RAM: 8GB (2X4GB) 1333MHz or 8GB (2x4GB) 1600MHz. I think someone said that I wouldn't notice the extra speed

I would like some help on Harddrives, I don't even know where it is in my computer even when I opened it up. Also need help on Optical drives for reading CD's or do the optical drives come with the case???

What about sound cards? Once again new on building computers Lol

The only thing concerns me is that the Motherboard is unknown, but I dont think that I would need to worry about it since it is on sale as a fully built PC. It comes with a 450watt PSU I think that I might need to replace it once I get it, and I already have a GTX 460 $100 so technically total projected spending is $660.00.

Also Since I have no idea when it comes to Processors, I was thinking of getting a intel i5 2400 but the PC ^ comes with a i5-2320 I compared them on the intel website but from my knowledge there isn't really a difference. So what I am asking is, is there a difference from these 2 processors? (note: not a really serious Gamer, just want a rig that can run good games on low to medium settings)

You're better off building your own stuff. When I think "I need a new computer", I don't think "I should shop around". I go to newegg to find what I can afford then price check on amazon. There's NO point in buying a pre-built computer for home use unless you need a laptop. Look at the parts I linked. That's ~$440 not including a video card (which you already bought). Why spend more money for slower parts? When you build custom, you can get parts in your budget to fit your need. If you want to get i5-2400, you can save another $20. And you could get a cheaper case, and save another $10-25. You could seriously build a $500 computer yourself that would smoke a $800 pre-built machine. Or you could go the other way and get a second 460 for sli, upgrade to a 600-650w psu and a sli capable mobo, and have more graphics muscle. And you'd STILL spend less than buying from cyberpower, or dell, or whoever. Build it yourself. Trust me, you'll save money, have a nicer machine, and it's fun/satisfying to do it yourself.

I think the only difference between h61 and h67 is h67 has sata 6Gb/s and usb 3.0. You probably don't need them. You'd need a 3rd gen SSD (the latest models) to use more than sata 3Gb/s. I'm not sure if there are many usb devices that would use 3.0, maybe new external hard drives, but you'll be fine with 2.0.

That board has a pci-x 2.0 16x slot, so you'll be fine with your gtx460. It doesn't have a lot of ports, but does include two pci-x 1x slots. That will work for a wireless LAN expansion card or you could go usb. If at all possible, I do suggest you go wired for a desktop, though.

There's no reason a 500GB drive wouldn't work for Windows 7 64-bit. It should be enough space for your OS, all the programs you need, tons of games and music, and some HD movies. For reference, I have about 30GB for my OS and apps (after disabling hybernation and system restore), and about 250GB for all my games. If you had similar files, that would leave about 180GB for music and movies (due to the way HDD manufacturers list size, 500GB is only 460GB usable disk space... you'll just have to trust me without me going on a rant). I actually have a media PC with a 1TB HDD where I keep my other files, but I think you'll be ok on space unless you're looking to archive HD movies/tv. You'll probably just have to watch them and delete them (or burn to disc).

As for that combo deal, that's probably about cheapest you're going to find right now. Hard drive prices are really expensive because of the flooding in Thailand and the cheapest HDD are $100. If this was 2 months ago, you could have gotten a 1TB drive for $50. An alternative is to use an existing HDD or try to buy a cheap used one, and then buy a $20 dvd burner.

After everything, though, buying those parts for $455 + $100 for windows 7 + $100 for the gtx460 you bought, you have a really nice system for $655. Way nicer than that $800 cyberpower system. Maybe price check to see if you can find those parts for cheaper (those are the best deals I could find on newegg), but if I were you with your budget, that's what I'd be buying.

Thanks dude

I am just gonna wait till the HDD's become cheaper/ back to original price. Since I heared about the flooding in thailand when reading some reviews on HDD's and I am not in a real need for a new PC its just that I felt that it is about time to get a new computer. BTW what is the difference between a SSD and a HDD?

But thanks for the help! I will definately use this kind of build in the near future!

A HDD is a hard-disk drive and a SSD is a solid-state drive. Hard-disk drives are mechanical (moving parts) long-term memory drives, while solid-state drives are non-mechanical (no moving parts) long-term memory drives. Each has their advantages and disadvantages. SSDs are faster and more expensive. HDDs are cheaper and have larger capacities.
