Power supply question

[Moopey]

Greetings everyone. I've already had a build topic here, and I'm really satisfied with the build I came up with your help. I'm currently building a budget gaming PC for my friend. I've managed to get him a really good one for 550KM ($380 of your money) but I've gotten a bit of a problem now. The graphics card I'm using for the build is GTX 750 Ti, I've read the specs and it requires minimum 400W and 12v 20A PSU. Since my friend is on such a tight budget, we're gonna reuse his 'old new' PSU; FSP400-60HLN. See, this PSU has the 12v ratings at 14A and 15A. There's two lines of 12v apparently. So, my question here is if this poses a problem, do the 12v amp ratings combine into 29A so it's safe to use or is there more at play here? The build is:

Biostar Hi-Fi B85S3,

Intel Pentium G3220 @ 3GHz,

Gainward GTX 750 Ti,

Kingston HyperX 4GB @ 1600 Mhz (Also reusing case, HDD and DVD drive)

Oh, yes I've got another question. Intel's site says G3220 supports DDR3-1333, so does that mean it supports 1333 maximum or minimum, eg. can I use 1600 with it? I know this won't be that big of an issue even if it only supports 1333 because the RAM will just get downgraded to 1333 MHz.

I have found this to be a very valuable tool. Just plug in the required hardware and click the 'calculate' button. That will tell you how much power supply you really need. I am going to disagree with Linus on multi-rail power supplies and state that a single rail is really the only way to fly.

Seems to be a good calculator, I remember the cooler master one adds like 100watt to the what the total should be

It still adds a little bit of leeway, for insurance sake. I don't think they could actually be sued for recommending 430W and someone getting a $5 430W and having it asplode on them, but there are a lot of stupid people willing to sue anyone over anything *cough*America*cough* and  they'll want to cover there asses. Still, I appreciate a bit of oversight in a PSU calculator, just not 100 Watts worth.

 

To be honest though, you'll get a better answer here, so here does my answer.

 

You need 20A on a single 12V rail. As that power supply does not have 20A on either single 12V rail, then I would not recommend it.

 

Assuming you live in the states, get this:

Highly recommended power supply for a budget.

Unless you know which cables/connectors are provided from which rails,and you are able do a load balancing act and plug from both of them to the gpu to fulfill the power requirement, I would say a big NO to using that psu.

 

Let me know if you any recommendation on a good psu replacement.

 

You can use the 1600mhz kit with that cpu no problem. 1333mhz is the minimum. But you will barely notice any difference between both anyways,unless you are using the igpu.

Hello everyone!

 

Just wanted to ask whether my power supply which is the CM Thunder M 620w would be able to handle the Sapphire R9-280x vapor-x tri-x.

 

I'm still new to this forum so please correct me if I have some mistakes.

 

Thanks!!

You should create a new thread next time. From the psu spec wise, yes it should be able to power that R9 280x just fine. But it is not quite an efficient psu with no 80+ rating at all

Unfortunately, only Corsairs available to me are in the 750w+ range and really expensive so I can't really get any, even though I'd really like it. I've found this Silverstone 400W PSU, says it has 25A single rail 12V and 300W on 12V so it should be fine for me. The calculator didn't have my processor but I chose some Ivy Pentium processor and I got 230W recommended so I think this PSU should be fine, even in the worst case scenario: if it is really not quality and gives 300W, it should still be fine. Adds more cost to me, but oh well. Here's the PSU I'm going with: http://www.silverstonetek.com/product.php?pid=247. If you think I shouldn't get this one, let me know since I'll be waiting a few more days before making the final purchase.

Is that the only psu available in your place? What is your budget? That Silverstone psu will work just fine. 750ti is a really efficient gpu and sips very little power.

Pretty much, there's some RealPower ones as well but they are much cheaper and I can't even find the spec list for it so it's probably not even that great. There's a frontier 500W one for 20$ which is obviously and probably really inexpensive, cheap and just bad, also it only gives 18A on its single 12V rail so it won't work here. My budget is G3220+750Ti and then get the cheapest mobo, ram and psu.

Yeah just get that Silverstone psu. My educated guess would be that your system will use just around 180w or less at full load.

Hmm, what do you think about switching to Ivy Bridge? The Ivy Bridge G2030 is pretty much the same as G3220 only Ivy Bridge (same price too), but the motherboard costs a lot less (128KM - Haswell, 85KM - Ivy Bridge). From what I've read and seen, they're pretty much the same with just some minor improvements. That would curb down the cost pretty significantly for me, as I'm looking to get the most efficiency for my money. Also, this motherboard says it supports PCIe 3.0 but with i5-3xxx and i7-3xxx, what does that mean? I can't use PCIe 3.0 with my Pentium CPU?

If you plan on upgrading the cpu in the future, the 1150 motherboard would be the better option. If not,get the 1155 as there's not much of improvement between those 2 beside different cpu socket and pcie 3.0. You shouldn't worry that much about the pcie 3.0 unless you have a high end multi gpus configuration.
