StarCraft® II

single vs multiple +12v rail

Posts: 745
I'm planning on buying a new PSU off of newegg and it says that it has 2 +12v rails. My motherboard only has one connector and I was wondering what would happen if I only have one plugged in.

And what is the preferred amount of wattage for a PSU for Starcraft?

Single or 2 rail it doesn't matter -- the plugs available are the same anyway.

As for the preferred PSU wattage, it depends on what graphics card you will use.

So I would be able to have only one of the connectors plugged into the motherboard and it would be fine? I'm still looking for a graphics card.

Im considering this one. SAPPHIRE Radeon HD 6670 1GB 128-bit DDR3 PCI Express 2.1 x16 HDCP Ready Video Card (11192-22-20G)
http://www.newegg.com/Product/Product.aspx?Item=N82E16814102988

And this power supply. SeaSonic G Series SSR-550RM 550W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS GOLD Certified Modular Active PFC Power Supply

If I could find a cheaper power supply (or maybe lower wattage that could support this one) and maybe a cheaper card, Id go for those instead.

You know there's a Black Friday deals going on around?

See this thread:

You also do not need 80 Plus GOLD.

Alright so heres what I'm going for

I went with 80 plus BRONZE instead

I'm still thinking about getting this card.

I have cheap intel e5800 3.2ghz processor. Do you think my system would bottleneck?

I would honestly recommend you save up more money; HD 6670 DDR3 is not a very good card and won't be a huge upgrade from what you get.

Radeon HD 7770 would be like day and night difference, and it's only $30 more.

Power supply is OK.

And yes, you should consider upgrading CPU sometime later, as StarCraft is fairly CPU intensive.

So the Radeon HD 7770 is fine with a 500w PSU? Radeon HD 7770 requires 450w, how much over can the PSU be?

I only have a pci-e gen 2 slot though. would a 3.0 card work?

and with these new parts it would bottleneck?

Don't believe what they say about power requirement; 500W is more than enough for most graphic cards, except the absolute top-ends that have terrible power consumption (IE) GTX 480), or dual-GPU on a single-card solution like GTX 690.

PCI-E slots are forward and backward compatible.

Your CPU may be a bottleneck.

Well thats not good. Ive been looking into the Radeon HD 7770 and it seems your probably right. I'm just trying to run SC2 with higher fps. Im only hitting 20-30 right now on the Hots beta.

Does memory type matter? I have DDR3 RAM, while the Radeon HD 7770 has DDR5

System RAM has no relation to video RAM, if that's what you mean by DDR3.

If you mean to ask DDR3 on graphics card vs. GDDR5, yes, there's a pretty big difference, GDDR5 is plain better.

Alright thats cleared then.

So basically, I won't really find any increase in fps unless I change my cpu?
Even getting a graphics card that wont bottleneck a e5800 wont do much?

You will still get a good FPS boost with normal games; it's just when there are tons and tons of units, FPS will be reduced.

I probably should have said this earlier but Im currently running on g45/43 chipset, and I can play 4v4s just fine, its just hots that runs 20-30 fps. and I play on the lowest settings possible.

Okay, so far I'm thinking about getting either:

SAPPHIRE Radeon HD 6670 1GB 128-bit DDR3 PCI Express 2.1 x16 HDCP Ready Video Card (11192-22-20G)
http://www.newegg.com/Product/Product.aspx?Item=N82E16814102988

This is the one I was thinking about first, however there might not be a whole lot of improvement. Though I have seen videos of people playing on this card and I dont think it looks too bad.

SAPPHIRE Vapor-X 100358VXL Radeon HD 7770 GHz Edition 1GB 128-bit GDDR5 PCI Express 3.0 x16 HDCP Ready CrossFireX Support Video Card http://www.newegg.com/Product/Product.aspx?Item=N82E16814102993

You recommend this one, but I dont want to bottleneck. Im sorta stuck with the e5800.

HIS H675FS1G Radeon HD 6750 1GB 128-bit DDR3 PCI Express 2.1 x16 HDCP Ready Video Card http://www.newegg.com/Product/Product.aspx?Item=N82E16814161395

Ive been reading various threads some say it might be good.

SAPPHIRE Radeon HD 7750 1GB 128-bit GDDR5 PCI Express 3.0 x16 HDCP Ready Video Card ( 11202-00-20G)
http://www.newegg.com/Product/Product.aspx?Item=N82E16814102969

same goes for this one.

Based on what Can I run it says. Everything is good except for the video card.

Buy this instead:

http://us.ncix.com/products/?sku=72479&vpn=R7770%2DPMD1GD5&manufacture=MSI%2FMicroStar&promoid=1030

If you can afford up to $120, this would be better:

Sadly, those two wont fit onto my motherboard. I think I will just have to settle for less for now. I think, unless I get a new motherboard and cpu, I can't really do much. I appreciate the help!

Why wouldn't it fit onto your motherboard? Unless your computer case is a slim-case, they will fit and work.

I think my RAM would get in the way. I could be wrong though.

It should clear, the very back of the card is aligned with the middle of the slot, but I can see why you are worried.

I'll leave it up to you.

Okay I see what you're saying now. So it should fit. Ill keep looking into it. Comparing to the Sapphire HD 7770 it requires at least a 450w power supply.

I'm still concerned about bottlenecking.
